Grass gis vector export
WebGRASS GIS 3D raster maps use the same coordinate system as 2D raster maps (row count from north to south) with an additional z dimension (depth) counting from bottom to top. The upper left corner (NW) is the origin. 3D rasters are stored using a tile cache based approach. This allows arbitrary read and write operations in the created 3D raster. Webt.vect.export exports a space time vector dataset (stvds) to a tar archive as either GML (using v.out.ogr ) or GRASS pack files. In addition to the pack or GML files, several metadata files are also created in the archive that describe the temporal layout. All time stamps are stored in the file "list.txt", for each map one row.
