Abstract

The invention discloses a vector spatial data model conversion method from a national standard model to a military standard model. The method comprises the following steps: S1, preparing vector data in a Shapefile file format; s2, traversing the Shapefile under the catalogue, and then layering the data according to a file list; s3, constructing a national standard code and military standard code classification comparison table; s4, performing hierarchical conversion on the national standard data stored in the database, and performing framing in the conversion process; and S5, converting the national standard code into a military standard code, calculating a map sheet where the image is located, obtaining an image type, judging whether the image is a directed point or not, and storing conversion process data in a military standard database. The working efficiency and the drawing efficiency are improved; automation of data model conversion is realized; batch vector data conversion is supported; and the generated vector map data meeting the military standard can be directly used for military map production operation.

Description

technical field

[0001] The invention belongs to the technical field of geographic information, and in particular relates to a vector space data model conversion method from a national standard model to a military standard model. Background technique

[0002] According to the coding rules of the national standard (GB25529-2010-T geographic information classification and coding rules) and the national military standard (GJB1839B-2012 military basic geographic information element classification and coding) coding rules, the coding comparison items are given, and the coding comparison table is constructed. Military standard data model such as figure 1 shown. GDAL is an open source spatial data transformation library under the X / MIT license agreement, which uses an abstract data model to express various supported file formats.

[0003] In the academic journal "Ocean Surveying and Mapping" in the fifth issue of September 2010, the idea of ​​data conversion is disclosed: construc...
