Through long-time development, researchers in different fields at home and abroad combine the fields, put forward a plurality of related theories and technologies from different angles, put forward different methods to create a three-dimensional geological model, and simulate a complex geological structure. For example, from the perspective of the storage structure, it can be generalized to grid-based data models, vector-based three-dimensional space models, and three-dimensional models of vector-grid hybrid structures; from the modeling morphology point of view, we can generalize into face models, voxel models, and hybrid models.

From a three-dimensional modeling data source, two-dimensional multi-source geological survey data are key bases of a three-dimensional geological model.

In particular embodiments, the two-dimensional multi-source geological survey data includes digital elevation models, remote sensing images, regional plan geologic maps, digital earth survey plane data, borehole data, profile data.

It should be noted that, the two-dimensional multi-source geological survey data related in the step is half-result data or result data obtained by geological professionals through collection or actual measurement and professional processing, and does not include original data and process data. For example: differential correction of multi-source topographic data, production of regional planar geologic map, topology error detection, inspection and arrangement of geological drilling data from engineering geological drilling, in-situ testing, logging and the like, and section data from different sources.

Step S20: and classifying and storing according to the two-dimensional multi-source geological survey data to obtain a plurality of geological space databases corresponding to different data types.

It should be noted that, classifying and storing refers to classifying and classifying two-dimensional multi-source geological survey data according to a scale range, generally, the multi-source geological survey data in one scale range should only have one space geometric element form, and the scale range should not span too much.

It should be understood that the two-dimensional multi-source geological survey data are respectively stored in different independent databases for management according to different data types after being classified and stored.

In the implementation, in order to lighten the data storage pressure and simultaneously meet the requirements of flexibly and conveniently calling each two-dimensional multi-source geological survey data in the data fusion and three-dimensional modeling work, a distributed data structure is adopted, an independent database is established to store each two-dimensional multi-source geological survey data in a distributed mode, and the independent database is managed and called in a form of cloud services such as restful or grpc.

Further, in order to classify and store the two-dimensional multi-source geological survey data, step S20 includes: determining unstructured geological survey data, a digital elevation model, remote sensing images, regional plane geologic maps, digital ground quality survey plane data, drilling data and geological section data according to the two-dimensional multi-source geological survey data; and respectively establishing independent databases for storing the unstructured geological survey data, the digital elevation model, the remote sensing image, the regional plane geological map, the digital ground quality survey plane data, the drilling data and the geological profile data to obtain a plurality of geological space databases corresponding to different data types.

In a specific implementation, the storage structure of the digital elevation model, the remote sensing image and the grid geologic map is shown in fig. 3, the storage structure of the vector geologic map is shown in fig. 4, the storage structure of the digital ground texture survey is shown in fig. 5, the storage structure of the geophysical prospecting inversion section is shown in fig. 6, the storage structure of the geological drilling is shown in fig. 7, and the storage structure of the geologic section is shown in fig. 8. The two-dimensional multi-source geological survey data facing the three-dimensional geological modeling, including the digital elevation model, the remote sensing image, the regional plane geological map, the digital ground quality adjustment drawing plane data, the drilling data and the section data are respectively built into independent databases for storage, and the distributed database structure is adopted for unified management, so that the two-dimensional multi-source geological survey data can be integrally stored.

It should be noted that in this step, the data may be generally classified according to a range of 1:10,000-1:50,000, 1:2,000-1:10,000, and 1:500-1:2,000, so as to ensure that the multi-source survey data has only one space geometric element form in a scale interval, for example, the landslide element is only a point element in the scale interval of 1:10,000-1:50,000, and is only a face element in the scale interval of 1:2,000-1:10,000.

By the method, the multi-source heterogeneous data characteristic of the two-dimensional multi-source geological survey data is reduced, the processing method and the storage structure of the two-dimensional multi-source geological survey data are defined, the interactive processing flow of modeling data with large data volume is simplified, and the storage management of the modeling data source is realized.

Further, in order to store different processing modes for different types of data, the steps of respectively establishing and storing the unstructured geological survey data, the digital elevation model, the remote sensing image, the regional plane geological map, the digital geosurvey plane data, the drilling data and the geological section data into independent databases, and obtaining a plurality of geological space databases corresponding to different data types include: converting the unstructured geological survey data into additional space geometric elements with geological information according to a preset scale range, and establishing an independent database for storage to obtain a first geological space database; interpolating and encrypting the digital elevation model to obtain an elevation reference digital Gao Chengmo molded surface, and storing the elevation reference digital elevation model surface in blocks according to a slicing mode to obtain a second geological space database; performing operation processing on the remote sensing image through radiation correction, geometric correction, gray stretching, color synthesis, wave band combination and image fusion, and storing the remote sensing image in blocks according to the wave band layer slice mode to obtain a third geological space database; obtaining a grid area plane geological map and a vector area plane geological map according to the area plane geological map, and respectively storing the grid area plane geological map and the vector area plane geological map in blocks to obtain a fourth geological space database; storing the digital geotexture adjustment drawing plane data according to a layer to obtain a fifth geological space database; obtaining stratum demarcation data, hydrogeologic data, comprehensive logging data and in-situ test data according to the drilling data, and respectively storing the stratum demarcation data, the hydrogeologic data, the comprehensive logging data and the in-situ test data to obtain a sixth geologic space database; and the geological profile data is stored by adopting the space index binary data type of the space database, so as to obtain a seventh space database.

The non-structural geological survey data such as photographs, videos, reports, etc. should be converted into a form of a certain spatial geometric element of the current scale by knowledge of geological professionals, and geological information contained in the non-structural geological survey data such as photographs, videos, reports, etc. should be added to the spatial geometric element as an attribute. For unstructured geological survey data such as photos, videos and reports, geological information needs to be decoded by geological professionals, then the geological information obtained through interpretation is used as an attribute to be added to space geometric elements, such as photos and videos in the process of geological survey, and the obtained geological information can be used as an attribute to be added to a geological survey point, so that a first geological space database is obtained.

It should be understood that, for the digital elevation model, the elevation reference digital Gao Chengmo profile of the surface three-dimensional geological model is constructed by fusing and connecting the digital topographic map, three-dimensional point cloud data and different-precision digital elevation models into a new irregular triangle network through interpolation, encryption and other methods, and adopting the methods of gram Lv Jin interpolation or inverse distance interpolation and the like. And storing the digital elevation model into a space database in a blocking mode according to a slicing mode, and simultaneously recording metadata information, coordinate projection information, boundary range information, the number of slices and contained slice record information of the digital elevation model, so as to obtain a second geological space database. Specifically, according to the interval requirement of the scale, a digital elevation model meeting the requirement is preferentially used; in addition, the digital elevation model can be obtained by fusing a digital topographic map, three-dimensional point cloud data and digital elevation models with different accuracies in GIS software.

In specific implementation, for the remote sensing image, the remote sensing image is processed through means of radiation correction, geometric correction, gray stretching, color synthesis, band combination, image fusion and the like, the remote sensing image is stored in a space database in a blocking mode according to a band layer-slice mode, metadata information, coordinate projection information, boundary range information, layering quantity, slice quantity and detailed record information of the contained band layer-slice of the remote sensing image are recorded, and a third geological space database is obtained. Specifically, according to the interval requirement of the scale, the remote sensing image meeting the requirement is used. The common remote sensing images comprise TM, landsat, ASTER, ALOS, worldView and the like, the remote sensing images are preprocessed in Erdas and Envi software, control points are selected, and the remote sensing images are corrected to correct spatial positions by using a software geometric correction function.

The regional plan geologic map is processed according to the data type. And (3) adopting the same processing method as that for the remote sensing image for the grid area plane geological map, selecting control points in GIS software, and correcting the grid area plane geological map to a correct spatial position by using a software geometric correction function. For a vector area plane geological map, using GIS software, projecting a point element map layer onto a digital elevation model of a corresponding scale in the Z-axis direction by using 'point projection to plane'; and projecting the boundary line of the line element layer and the surface element layer after the nodes in the encryption line on a digital elevation model of a corresponding scale in the Z-axis direction by using the line projection to the surface, thereby obtaining a fourth geological space database.

It should be understood that the digital geosurvey plane data includes digitized vector geosurvey plane data obtained by mutual verification of engineering remote sensing geoplan interpretation data, field geosurvey points, geosurvey point boundaries, field geosurvey routes, and the like. The digital ground quality survey plane data is divided into different layers according to the "element-point/line/surface layers". Projecting the dot element layer onto a digital elevation model of a corresponding scale in the Z-axis direction by using 'dot projection onto a plane'; and projecting the boundary line of the line element layer and the face element layer after the nodes in the encryption line on a digital elevation model of a corresponding scale in the Z-axis direction by using the line projection surface. In addition, the original recorded space Z-axis information can be adopted for the three-dimensional digital ground quality transfer drawing data which is directly collected through the field ground quality transfer drawing, and projection processing is not needed. And finally, storing the digital ground quality adjustment drawing data into a space database according to a layer division table, wherein geometric space form and coordinate projection information of the digital ground quality adjustment drawing data are stored by adopting space index binary data types of the space database, and geological attribute information of the digital ground quality adjustment drawing data is connected with geological elements of the corresponding digital ground quality adjustment drawing data by using a structured two-dimensional table to obtain a fifth geological space database. Specifically, GIS software is used, and a 'point projection onto surface' is used for projecting a point element layer onto a digital elevation model of a corresponding scale in the Z-axis direction; and projecting the boundary line of the line element layer and the face element layer after the nodes in the encryption line on a digital elevation model of a corresponding scale in the Z-axis direction by using the line projection surface. In addition, the original recorded space Z-axis information can be adopted for the three-dimensional digital ground quality transfer drawing data which is directly collected through the field ground quality transfer drawing, and projection processing is not needed.

In specific implementation, compared with other investigation data, the drilling data is three-dimensional data in space, can reflect three-dimensional geological information most intuitively, accurately and in detail, is an important source of comprehensive investigation data, and mainly comprises stratum demarcation data, hydrogeological data, comprehensive logging data, in-situ test data and the like. The specific processing process of the drilling data is as follows:

extracting, mapping, cleaning and converting basic information of the drill hole, in particular three-dimensional space coordinate information of the depth of the drill hole and the hole opening of the drill hole, thereby determining the space position and depth of the drill hole. The geometrical space position and coordinate projection information of the drill holes are stored by adopting the space index binary data type of a space database, and the related information such as depth, aperture, inclination azimuth angle, inclination zenith angle and the like is connected with the corresponding drill holes by a structured two-dimensional table.

The boundary data of the drilled stratum is mainly obtained through engineering geological drilling, is a contact surface between the upper stratum and the lower stratum, and can uniquely determine the current stratum through the stratum top surface elevation and the stratum bottom elevation. And connecting formation lithology related information such as the depths of the top and bottom plates of the drilling formation, the formation name, the formation yield, the formation age and the like with the corresponding drilling holes in a two-dimensional table.

The hydrogeologic data of the drill hole is mainly obtained through a hydrogeologic test of the drill hole, and the hydrogeologic test and engineering geological drilling are commonly used for drilling the drill hole, so that the hydrogeologic test comprises test result data of a water lifting test, a water pumping test, a water pressing test, a water injection test, a permeability coefficient, a unit water inflow amount, a unit water absorption amount and the like, and the hydrogeologic data of the drill hole is connected with the corresponding drill hole through a two-dimensional table. For water lifting tests, water pumping tests, water pressing tests, water injection tests and the like, data types such as json or blobs and the like are adopted for storage in the form of test record result-time.

The comprehensive logging data comprises various geophysical exploration tests such as a ground stress test, a gas test and a rock-soil mass wave velocity test, and is commonly used for drilling holes together with engineering geological drilling, so that the information such as the depth of the top and bottom plates of a comprehensive logging interpretation stratum and the interpretation stratum is connected with the corresponding drilling holes through a two-dimensional table. In addition, for the tests such as the ground stress test, the gas test and the rock-soil mass wave velocity test, the data types such as json or blob are adopted for storage in the form of test record result-time/depth.

The in-situ test data mainly comprises an interpretation stratum and an interpretation stratum lithology parameter combination, and the in-situ test is also used for acquiring deep underground stratum layering information in a drilling mode, so that the in-situ test basic information adopts a storage structure identical to that of the drilling basic information. In addition, the information of the interpreted stratum top and bottom plate depth, interpreted stratum and the like is connected with the corresponding in-situ test holes through a two-dimensional table, and the interpreted stratum lithology physical parameter combination is stored in a test record result-depth mode through json or blob and other data types, so that a sixth geological space database is obtained.

In the step, the geological drilling data are processed according to engineering geological drilling, drilling test, comprehensive logging and in-situ test. And (3) using a database SQL programming to store the basic information, the test result, the test record and other data in a json, blob or two-dimensional table form.

It should be understood that a geologic profile is a vertical representation of regional geologic structures on a cut line, using polylines or curves to reveal regional topography, stratigraphic ordering, and geologic structures. The geological profile data integrates the topographic data and the stratum data, and compared with the drilling data, the geological profile data can reflect the lamellar structure and the topological relation among the geologic bodies through manual interpretation by geological specialists. The geological profile data mainly comprises a geological map profile, a geophysical prospecting profile, a measured profile, a drilling continuous layer profile and a map cutting profile.

In a specific implementation, the geological profile data is processed as follows:

geological elements such as stratum lithology surface, geological boundary line and construction boundary line in the geological section are divided according to element-point/line/surface layer. The X, Y coordinates on the map of the geological elements are stored by adopting the space index binary data type of the space database, and meanwhile, the geological attribute information of the geological elements is connected with the geological elements of the corresponding section by using a structured two-dimensional table.

And projecting the earth surface trace line corresponding to the geological section on a digital elevation model of a corresponding scale in the Z-axis direction by using a line projection plane, and storing geometrical space morphology and coordinate projection information of the earth surface trace line after conversion by adopting a space index binary data type of a space database.

And setting a geological profile conversion control point, storing X, Y coordinates and actual three-dimensional space coordinates on the geological profile of the control point in the 'on-map-actual' pair by adopting the space index binary data type of the space database, and connecting the corresponding geological profile.

For the geophysical prospecting inversion section, X, Y coordinates of inversion interpolation points are converted into actual three-dimensional space coordinates through control points in pairs of 'on-graph-actual', and a three-dimensional geophysical prospecting inversion section is constructed by adopting methods such as gram Lv Jin interpolation or inverse distance interpolation. And storing the three-dimensional geophysical prospecting inversion section into a space database in a blocking mode according to a slice form, and simultaneously recording metadata information, coordinate projection information, boundary range information, the number of slices and contained slice record information of the geophysical prospecting inversion section.

The geological section is divided into three parts. The geological profile data is only a vector geological profile for CAD or GIS related formats, and comprises geological profile geological elements, surface track lines and conversion control points. Firstly, a geological element in a geological section is processed by a reference vector area plane geological map processing method. In contrast, the geologic profile does not need to be corrected for projection to a real spatial location, only storing X, Y coordinates on the map of geologic elements. And secondly, for the ground surface track line and the conversion control points, using database SQL programming to store geometrical space form and coordinate projection information of the ground surface track line in the actual space and a pair of control point coordinate pairs of 'on-the-map-actual'. And finally, for the geophysical prospecting inversion profile, converting the inversion interpolation point into an actual three-dimensional space coordinate by using a conversion control point, and converting the inversion interpolation point into a three-dimensional geophysical prospecting inversion profile in Surfer software.

In this way, a way of handling the different data types and how to store them in a separate database is achieved.

The grid independent database is obtained by processing the grid area planar geological map used for reference mapping through means such as geometric correction, space projection conversion and the like, storing the grid area planar geological map into a space database in blocks according to an RGB layer-slice mode, and simultaneously recording metadata information, coordinate projection information, boundary range information, RGB layer number, slice number and contained RGB layer-slice detailed record information of the grid area planar geological map.

It should be understood that the geological elements of the vector area planar geological map, such as the lithology surface, the geological boundary, the construction boundary, the occurrence points, etc., are divided by the element-point/line/surface layer. Projecting the dot element layer onto a digital elevation model of a corresponding scale in the Z-axis direction by using 'dot projection onto a plane'; the boundary line of the line element layer and the surface element layer after the nodes in the encrypted line are projected onto the digital elevation model of the corresponding scale in the Z-axis direction by using the line projection to the surface, and the purpose of the encrypted nodes is to enable the boundary line of the line layer and the surface layer projected onto the digital elevation model to be completely overlapped with the digital elevation model. Finally, the geological elements of the vector region geological map after projection transformation are stored in a space database according to element-point/line/surface layer sub-tables, the geometric space form and coordinate projection information of the geological elements are stored by adopting space index binary data types of the space database, and the geological attribute information of the geological elements is connected with the geological elements of the vector geological map of the corresponding region by a structured two-dimensional table, so that a vector independent database is obtained.

In a specific implementation, after the grid independent database and the vector independent database are obtained, the grid independent database and the vector independent database are combined into a fourth geological space database.

And setting nodes in the shallow surface geological boundary and nodes at the geological drilling stratum boundary point as control nodes, modifying the low-reliability geological boundary according to the high-reliability geological boundary, and performing DSI (discrete smooth interpolation DSI theory) on the connecting line.
