All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, a flow chart of a method for constructing a homeland space planning "a map" according to an embodiment of the present invention is shown.

The three-adjustment result data is required according to the third national soil investigation technical regulations (release of 1 month in 2019), and includes, but is not limited to, rural land utilization status investigation results (quantity, distribution and quality status of agricultural lands such as cultivated land, garden land, forest land, grass land and the like, and the distribution and utilization status of various lands such as cities, construction towns, villages, independent industrial and mining areas, water conservancy facilities and the like), and urban village internal land utilization status investigation (urban village internal business suit, industry, warehouse, residence, public management and public service, special land and the like); the basic mapping data comprises, but is not limited to, basic geography, image map, topographic map and the like; the resource investigation data comprises, but is not limited to, data such as geographical national condition census, water resource investigation, forest resource investigation, wetland resource investigation, ocean resource investigation, mineral resource investigation, geology and environment investigation and the like; the resource sensing data comprises, but is not limited to, data such as water environment quality monitoring, atmospheric environment quality monitoring and the like.
S12, performing data format conversion processing on the acquired state data related to the territorial space so as to convert the data format of the state data related to the territorial space into a target data format.
Specifically, the current situation data required for compiling the homeland space planning "a map" includes multiple types of data such as basic mapping, resource investigation, resource perception, etc., and these data may include CAD (Computer AIDED DESIGN, aided design) and GIS (Geographic Information System ) related formats; wherein, the CAD related format mainly comprises DWG of AutoCAD, DXF format and DGN format of MicroStation; the GIS related format mainly comprises data formats of platforms such as ArcGIS, mapGIS, mapInfo, superMap; for example, the topographic map result data of basic mapping adopts DWG and DXF formats of AutoCAD, and the land change investigation result data adopts ArcGIS or MapGIS formats. Therefore, in order to form a unified working base map, the format conversion needs to be performed on the current data with different formats, so that the data format of each state data related to the homeland space is converted into a unified data format.
And S13, performing coordinate conversion processing on the acquired state data related to the territorial space so as to convert the coordinates of the state data related to the territorial space into the coordinates under a target coordinate system.
It should be noted that, due to historical reasons, the coordinate systems adopted by departments of planning, construction, homeland, environmental protection, water conservancy, agriculture and the like of various cities in China are not unified at present; for example, the planning or construction department mostly adopts the local coordinate system of the city, while the homeland or land management department mostly adopts the 1980 western security coordinate system, other departments or adopts the Beijing 1954 coordinate system, the western security 1980 coordinate system, the WGS84 coordinate system, and the like, and the homeland space planning and establishment needs to collect the existing data of the different departments, and because the coordinate systems of the existing data of all departments are inconsistent, one of the first works of homeland space planning and establishment is to perform coordinate transformation on the collected current data according to the data standard or technical guideline of planning and establishment, so as to form the homeland space association current data with unified coordinate system.
S14, generating a working base map according to the state data of the national soil space association after the data format conversion and the coordinate conversion.
Specifically, after data format conversion processing and coordinate conversion processing are performed on the state data related to the homeland space, a working base chart is formed by using the processed state data related to the homeland space.

Specifically, the homeland space planning data are acquired, and the homeland space planning data are converged on the basis of the working base map, so that a homeland space planning 'map' which can be overlapped and opened layer by layer on the basis of the working base map is formed.
It should be noted that, the execution sequence between the step S12 and the step S13 is not limited in the embodiment of the present invention; for example, step S13 may be performed first, then step S12 may be performed, or step S12 and step S13 may be performed simultaneously, which will not be described herein.
In the embodiment of the invention, the acquired state data related to the homeland space are subjected to data format conversion and coordinate conversion, a unified working base map is generated according to the processed state data related to the homeland space, and homeland space planning data are converged in the working base map, so that a 'one map' of homeland space planning is formed. In the embodiment of the invention, the unified working base map is formed by adopting the three-tone result data, the basic mapping data, the resource investigation data and the resource perception data, and the homeland space planning data are converged in the working base map to form the homeland space planning 'one map', so that the accuracy of the constructed homeland space planning 'one map' is effectively improved.
In a preferred embodiment, in step S12, arcGIS software may be used to perform a data format conversion process on each acquired state data related to the homeland space, where the data format conversion process specifically includes:
1) Selecting Data Interoperability Tools (data integration) tools in the ArcGIS software module ArcToolBox;
2) A Quick Import (quick import) tool is selected, and in the pop-up data import dialog box, the current data to be imported is selected to be converted, and the tool automatically completes the format conversion.
3) After the format conversion is completed, the ArcGIS software module Arcmap is used for editing the converted data.
It should be noted that, here, only one specific implementation manner of performing the data format conversion process is provided, the specific manner of performing the data format conversion process is not limited in the embodiment of the present invention, and those skilled in the art may also perform the data format conversion process in other manners according to the specific situation in practical application.
In a preferred embodiment, in step S13, coordinate transformation processing is performed on each acquired state data related to the territorial space by using a three-parameter method or a seven-parameter method.
Specifically, arcGIS software may be used to implement coordinate conversion processing for each acquired state data related to the territorial space by using a three-parameter method or a seven-parameter method, where the process of the coordinate conversion processing specifically includes:
1) Determining three parameters (delta X, delta Y, delta Z) in the three-parameter method or seven parameters in the seven-parameter method respectively;
2) Selecting DATA MANAGEMENT Tools in ArcGIS software module ArcToolBox;
3) Selecting Create Custom Geographic Transformation (creating a custom coordinate conversion) tools, and in a pop-up custom coordinate conversion dialog box, firstly selecting state data (such as special traffic planning data of a certain city) related to a territorial space which needs to be subjected to coordinate conversion;
4) Selecting a three-parameter method, and inputting three parameters (delta X, delta Y and delta Z) in the step 1) to finish conversion; or alternatively, the first and second heat exchangers may be,
And selecting a seven-parameter method, and inputting seven parameters in the seven-parameter method determined in the step 1) to finish conversion.

As shown in fig. 2, in a preferred embodiment, in order to update the working base map in time to ensure the accuracy of the "one map" of the built homeland space plan, the method for building the "one map" of the homeland space plan of this embodiment further includes steps S21-S24:
S21, after the working base map is generated, the generated working base map is simultaneously stored in a database of a background;
s22, when new state data related to the state soil space is obtained, updating corresponding layers in the generated working base chart according to the new state data related to the state soil space to obtain updated layers;
S23, updating the corresponding layers in the working base graph of the database according to the updated layers;
S24, converging the homeland space planning data in the updated working base map to update a map of the homeland space planning.
It will be appreciated that a work base graph includes data for basic mapping results, resource surveys, resource awareness, etc., and thus these current data in the work base graph need to be updated in time. In the process of planning and compiling the homeland space and applying the later achievements, the current bottom map data also need to be updated in time; the updating in time can be divided into regular updating and real-time updating according to the relative length of the updating time or period, and a base map updating mode of the current state of the national and local space planning is as follows: the basic mapping results such as basic geography, image map, topography map and the like are updated regularly, the resource investigation data such as third national investigation, geographical national condition census investigation, water resource investigation, forest resource investigation, wetland resource investigation, ocean resource investigation, mineral resource investigation, geology and environment investigation are updated mainly in a regular manner, real-time update is performed as an auxiliary, and the resource perception data such as water environment quality monitoring, atmospheric environment quality monitoring and the like are updated in a real-time manner. Whether updating regularly or in real time, the purpose is to update a base map in time, so as to ensure the behavior of the national and terrestrial space planning Zhang Detu.
Specifically, the generated work base map is located in a front-end data platform because the generated work base map needs to be displayed, and after the work base map is generated, the generated work base map is stored in a background database at the same time. When new state data related to the state soil space is obtained, correspondingly updating a working base map in a data platform positioned at the front end according to the new state data related to the state soil space, and obtaining an updated map layer in the working base map; and then, updating the corresponding layers in the working base graph in the database according to the updated layers, thereby completing the updating process of the whole working base graph. And after the working base map is updated, the homeland space planning data are assembled again, so that an updated homeland space planning 'one map' is obtained. According to the embodiment of the invention, when the new state data related to the homeland space is acquired, the working base map is updated in time, and the homeland space planning 'one map' formed by the working base map is updated in time, so that the accuracy of the constructed homeland space planning 'one map' is ensured.
Further, each element in each layer of the embodiment has an additional attribute; wherein the additional attributes include unique identification code, acquisition time and update time; then the first time period of the first time period,
In step S23, the updating the corresponding layer in the working base map of the database according to the updated layer specifically includes the following steps S231-S236:
s231, according to the updated layers, obtaining corresponding layers in the working base graph of the database as layers to be updated;
S232, comparing each element in the layer to be updated with each element in the updated layer;
s233, deleting any element in the layer to be updated when the unique identification code of the element is different from the unique identification codes of all elements in the layer to be updated;
s234, when the unique identification code of any element in the updated layer is different from the unique identification codes of all elements in the layer to be updated, adding the element in the updated layer to the layer to be updated;
s235, when the unique identification code of any element in the updated layer is the same as the unique identification code of any element in the layer to be updated, judging whether the update time of the element in the layer to be updated is the same as the acquisition time of the corresponding element in the layer to be updated;
s236, when the update time of the element in the layer to be updated is different from the acquisition time of the corresponding element in the layer to be updated, replacing the element in the layer to be updated with the corresponding element in the layer to be updated.
It will be appreciated that each element in each layer of the working base graph stored in the database has an additional attribute, and each element in each layer of the generated working base graph (the data platform at the front end) has an additional attribute. Specifically, for the work base map stored in the database, taking all the ground feature elements in each layer in the work base map in the database as elements, and adding a unique identification code, acquisition time and update time on the basis of the existing attribute of each ground feature element to serve as the additional attribute of the ground feature element; for the working base map of the data platform at the front end, before updating, the additional attribute of each element in each layer of the generated working base map is the same as the additional attribute of the corresponding element in the corresponding layer in the working base map in the database, and after updating the corresponding layer in the generated working base map according to the new state data related to the territory space, generating a new unique identification code, acquisition time and update time for the newly-increased ground feature elements in the updated layer, wherein the acquisition time and update time of the newly-increased ground feature elements are all the current time; for the modified (including attribute and graph change) feature elements, the unique identification code and the acquisition time of the feature elements are kept unchanged, and the update time is modified to be the current time; and directly deleting the feature elements to be deleted. Thus, different elements in the updated layer and the layer to be updated can be determined according to the additional attribute of the element in the updated layer in the generated working base graph and the additional attribute of the element in the layer to be updated in the working base graph stored in the database, so that the layer to be updated is updated.
Specifically, in step S233, when the unique identifier of any element in the layer to be updated is different from the unique identifiers of all the elements in the layer to be updated, it indicates that the element corresponding to the element in the layer to be updated has been deleted, and thus the element in the layer to be updated is deleted. In step S234, when the unique identifier of any element in the updated layer is different from the unique identifiers of all elements in the layer to be updated, it indicates that the element in the updated layer is an added element, and thus the element is written into the layer to be updated.

publishing each homeland space planning data into a standard OGC service;
And calling the corresponding homeland space planning data through the OGC service.
It should be noted that, from the view of planning level and content type, the new national soil space is divided into three categories of five levels, and five levels are corresponding to the administrative management system of China from the longitudinal view, and five levels are the national level, provincial level, urban level, county level and village and town level; three categories refer to the types of planning, which are classified into overall planning, detailed planning and related specialized planning. Preferably, the homeland space planning data of the present embodiment includes data of an overall plan, data of a detailed plan, and data of a special plan.
The embodiment of the invention adopts a map convergence method of SERVICE GIS (service GIS) homeland space planning, namely adopts standard OGC (Open Geospatial Consortium, which is a non-profit, internationalized and voluntary negotiated standardization organization, and mainly aims at making space information and standard service related to location service, and the problem of convergence of a map of homeland space planning among different platforms and different levels is solved by publishing various general plans, detailed plans and special plans of each level into standard OGC service including data service and functional service, so as to support sharing and convergence among heterogeneous GIS platforms, such as a certain GIS platform is adopted in a city level, and homeland space planning (including general planning, detailed planning and special planning) of the city level is published into standard OGC service which can be called and accessed by a provincial or national level platform or system. In addition, the convergence mode provided by the embodiment of the invention can share the map data of the homeland space planning among departments such as the national level, the province level, the city level, the county level, the village-town level and the like, and can also release specific application functions (such as space analysis functions based on overall planning and the like) in a Web service mode for other departments or units to directly call.
Preferably, the embodiment may use ArcGIS software to issue the homeland space planning data of a certain city into a standard OGC service, and the process specifically includes:
1) Opening a map of a certain urban and homeland space plan to be released into OGC service in an ArcGIS software module Arcmap;
