Map Shape Classification | |
---|---|
Name | SYSCLS_MAPSHAPE |
Inheritance | SYSCLS ARCHIVECLASSIFICATION |
Namespace | System.Classification.Map |
ID | {5DF644AE-E0EC-43B0-9F55-A20BD0A2488C} |
Purpose | Marks an archive document as Map Shape file |
Version | 3.6.0+ |
If a Document object fullfills the Map Shape Classification it contains the necessary files for a Map Shape as compressed archive (zip).
The shapefile is in fact a grouping of several files formatted to represent different aspects of geodata:
- .shp — shape format; the feature geometry itself.
- .shx — shape index format; a positional index of the feature geometry to allow seeking forwards and backwards quickly.
- .dbf — attribute format; columnar attributes for each shape, in dBase IV format.
There are also several optional files in the shapefile format. The most significant of these is the .prj file which describes the coordinate system and projection information used.
