The method specifically comprises the steps of establishing a nationwide uniform surveying and mapping benchmark and surveying and mapping system, carrying out basic aerial photography, acquiring remote sensing data of basic geographic information, measuring and updating national basic scale maps, image maps and digital products, and establishing and updating the basic geographic information system. The basic mapping is carried out in the national or local area according to the national unified planning and technical standard.

Example one

The embodiment aims to solve the problem that the current mapping software can only map one version of map data, and provides a multi-version local geographic information integrated mapping method for achieving the aim.

And establishing identification tables of all data versions and drawing templates of all data versions in advance.

(1) Establishing an identification mark table

The identification mark table comprises corresponding relations between all data versions and identification marks. Specifically, the identifier table includes a plurality of fields such as a version number, a special layer, an attribute, a classification code, and a graph name, where the special layer, the attribute, and the classification code are identifier fields.

After map data is produced, visualization of the data is only shown in the form of three types of elements, namely points, lines and surfaces, but each of the forms of the points, the lines and the surfaces comprises a plurality of layers, for example, the data in the form of the surfaces comprises layers of reservoirs, lakes, residential sites, construction sites and the like, the data in the form of lines comprises layers of roads, rivers and the like, and the information of the layers can be only shown in an attribute table. The point, line and surface forms all correspond to an attribute table, wherein fields such as element codes, place names, place codes, located maps and the like are recorded.

In this embodiment, the identification identifier is identified through the special layer, the attribute and the classification code.

For each data version, determining the identification thereof according to the following steps:

①, comparing the version with the layers of other versions, finding out whether the version has layers without other versions, if so, using the layers without other versions as the identification mark, writing the identification mark into the 'layer' field of the corresponding version in the identification mark table, otherwise, executing step ②, for example, if the number of the layers of version 1 is more than that of other versions, finding out the more layers, and marking as the identification mark of version 1.

② comparing the version with the attribute table fields of other versions, finding out whether the version has fields that other versions do not have, if yes, using the fields that other versions do not have as the identification mark of the version, writing the identification mark into the' field of the corresponding version in the identification mark table, otherwise, executing step ③;

③ comparing the version with the land codes of other versions, finding out whether there is a land code that other versions do not have in the version, if so, using the land code that other versions do not have as the identification mark of the version, writing the identification mark into the 'land code' field of the corresponding version in the identification mark table, otherwise, indicating that the version has the version consistent with the version data standard and shares the identification mark with the version consistent with the data standard.

The data version automatic identification mark is determined by a special layer, an attribute and a classification code, but the data version automatic identification mark is not limited to this, and any feature unique to the version data can be used as the data version automatic identification mark.

(2) Creating drawing templates for all data versions

Each data version corresponds to a drawing template, namely a configuration file, and the drawing template comprises element and surface feature layer sequence configuration, symbol configuration, drawing rule configuration, marking rule configuration and administrative region adjacency list configuration. The charting template for each data version is based on the charting standard for that version.

Specifically, each drawing template includes information such as data and layout views, the sequence of each layer, color, symbol size, field on which the label is based, and size of the label text when drawing is performed on the corresponding data version.

On the basis, the multi-version local geographic information integrated drawing method comprises the following steps:

step 1: receiving a chart data file; the mapped data file includes graphic data and attribute data.

Step 2: judging the version of the mapping data file according to the identification identifier table;

and determining the version of the mapping data file according to the identification mark contained in the mapping data file. Specifically, according to the identification marks of the versions, the identification mark of which version the mapped data file contains is sequentially searched, so that the version to which the mapped data file belongs is determined.

And step 3: calling a drawing template of a corresponding version, and adjusting a data view and a layout view;

the drawing tool provides functions of data view, layout view, layer management, common tools and the like. The data view provides a browsing interface for the geographic information data. The layout view provides a drawing interface for the geographic information data. The layer management tool is used for controlling layers of the geographic information data, and can control addition, deletion, display, closing and the like of the layers.

And 4, step 4: according to the drawing template, map symbolization is carried out;

the map symbolization comprises the following steps: the method comprises the steps of sequencing three elements of points, lines and surfaces and contained layers, modifying the color of each layer, modifying the shape and size of symbols and the like, and finishing outside the graph, hooking the symbols and the like aiming at the point element layers.

The map symbolization also includes collision detection and handling. The conflict detection and processing function is to optimize the drawing effect and detect and process the drawing conflict of all elements one by one after the automatic symbolization reaches the basic drawing effect, and the conflict detection is to detect whether the superposition, the intersection and other phenomena of map symbols exist. The processing link is implemented by man-machine interaction, and the conflict detection and processing function detection is used for finding problems and manually editing and modifying the problems, so that a high-level drawing effect is achieved.

And 5: drawing based on the symbolized map; the graph is exported or printed.

Those skilled in the art will appreciate that the map export format may be set to various file types such as MXD, JPEG, AI, TIFF, PDF, etc.
