In this embodiment, the data set generated by the cas software is 28 layers, the result data set is 31 layers, and the layer names and the stored elements are inconsistent. Therefore, the case software can not directly obtain normative data results, and the results output by the case software have the problems of non-normative code and non-normative element classification (the layer names and the elements are inconsistent).

Referring to fig. 3, fig. 3 is a schematic structural diagram of an embodiment of a cases data processing method according to the present application, in the embodiment, the cases data processing method may include steps S110 to S130, where each step is as follows:

s110: drawing a terrain basic data set in a dwg format based on drawing in a cas software environment.

cas software is a software system developed based on a CAD platform and integrating the functions of terrain, cadastral, space database construction, engineering application, earth and stone calculation amount and the like. Can be used for carrying out land survey delimitation, urban component investigation and earth calculation functions.

Land surveying and delimiting: the land surveying delimitation is an important content of a 'gold-soil engineering' plan, and the contents of defining a land use range, determining a boundary position, calculating land area and the like are technical service work for providing scientific and accurate basic data for land approval and cadastral management of a national and soil resource administration department. The survey delimitation report may also be updated according to the land survey delimitation protocol.

Urban component survey: the city component management method is a method for managing materialized city management objects as city components, positioning the city components on a ten-thousand-meter unit grid map according to geographic coordinates by using a geocoding technology, and performing classification management on the ten-thousand-meter unit grid map through a grid city management information platform. Each component is given a number of bit codes, which are marked in the corresponding ten-kilometer unit grid, and are equivalent to the 'identity card' of the component. The main functions of CASS urban component investigation are: the method comprises the steps of city component uniform coding, city component drawing and displaying, uniform attribute data structure, and convenient attribute data entry, modification, inquiry and statistics.

The earthwork calculation function: the CASS system provides rich earth calculation methods such as a square grid method, a DTM method, a contour method and a section method, and can flexibly adopt appropriate earth calculation models for different engineering conditions.

In this embodiment, based on a drawing in a cas software environment, a terrain basic data set in a dwg format is drawn, where the terrain basic data set in the dwg format may include 28 image layers and a 7-bit code.

S120: and carrying out data processing on the terrain basic data set to obtain the attribute of the terrain of each map layer.

In the case software environment, the drawing of the surface feature mainly comprises a text, a point, a line and a closed line (surface), and with the help of a software express function module, more attributes of the surface feature can be checked.

S130: and combining a preset conversion rule, performing data element classification, similar combination and code conversion on the terrain basic data set according to the attributes of the terrain to obtain a result terrain data set, and outputting the result terrain data set.

The preset conversion rule may be formulated according to the specification requirements, for example, according to the standard specification of "1: 5001: 10001: 2000 basic geographic information data element attributes "to make conversion rules so that the final output production terrain data set meets specifications. For example, according to "1: 5001: 10001: 2000 basic geographic information data element attribute, the final output result terrain data set comprises 31 layers and 8-bit code codes.

According to the attributes of the ground features, the terrain basic data set is divided into four types of elements, wherein the four types of elements comprise texts, points, lines and surfaces. The code conversion process is to convert the cas codes of the corresponding ground objects into the classification codes of the city update through the international codes through the unique identification codes.

For example, in a transportation and facility layer under cas software environment, in this aspect, under the tool module, DLSS layer data is read, all attributes thereof are exposed (read), attributes related to specifications are proposed, data processing is performed, and data sets of the layers are reclassified and output: text (note), point, line and surface (closed line), then making code conversion, and finally making data output. Referring to fig. 4-5, fig. 4 is a schematic diagram of layers of an embodiment of a terrain basis dataset and a production terrain dataset of the present application; fig. 5 is a schematic flow chart of an embodiment of DLSS layer output of the present application.

The outcome terrain dataset may be stored in an outcome database. Optionally, the achievement database is an ArcGis vector database. As ArcGis software has no function of converting code codes in batches, manual conversion is needed, the process is complicated and complicated, and the efficiency is low. Therefore, the method and the device can also improve the conversion efficiency of the code.

The cas data processing method is simple to operate, saves enterprise cost, does not need to specially and independently customize related software, and can obtain normative data results by using the tool; the database can be output by one key, so that complicated procedures and data distortion caused by human factors are avoided, and the working efficiency is greatly improved; if the tool is slightly changed, such as the coding comparison table is changed, the data achievement of other mapping tasks can be met.

In order to more clearly illustrate the cas data processing method of the present application, the following description is made in conjunction with the case:

basic data survey of City update project

1) And (3) drawing related ground features by cas software, and after the drawing is finished, preprocessing data, wherein when the attribute of the ground features is checked, the element classification and the coding of the ground features do not meet the standard of the technical index related to the project if the existing topological problem is processed. Wherein, the concrete room of the original data set belongs to JMD layer, and the code is 141111; the result data set concrete room belongs to the RES _ PY layer and is coded as 31030131.

2) And (4) performing data conversion on the original data set to output a gdb database.

3) The project is applied to the project, the work of cockamamie and low efficiency is avoided, the work efficiency of the project is greatly improved, the final project is successfully checked and accepted, and therefore the project can be popularized to the middle of actual production and application.

In summary, most enterprises currently use experience-based cases software, which cannot export shape files. The method can export the shape file and the database by consuming time intervals and expanding the attributes of the seamless belt; the functions of the flow modules are perfect, the modules are relatively independent, and the conversion from the dwg format to the shape format or the gdb database result of other surveying and mapping results can be met only by slightly modifying certain contents, such as modifying an encoding comparison table, element classes or names contained in the layers, and the like.
