[GRASS-user] Pygrass vector package: write geometric feature in a specific layer
Hello all, I'm writing a GRASS module with pygrass to import data from a text file into a new vector map. Those data have topological relationships: they are nodes and links of a sewer network. But those objects may have different types of attributes. For example a link could be a pipe or a pump. Therefore I think that the use of vector layers is the right way to store those data. With pygrass I managed to set DB links and import the attributes in different tables. But the only way I've found to change the layer of geometric features is with .open(mode='w', layer=X). This works well for one layer, but I've to write different objects in different layers. I tried to close the map and re-open it with another layer, but if I pass mode='rw', the map refuse to open because the layer not yet exist, and with mode='w', it overwrite the existing map. I know there is a way to create a new map for each layer and then use existing GRASS modules to merge them into a single map, but I feel that this is overly complex. So my question is: Is there a way to decide which layer to write new objects, and change this layer during the import process? I'm using grass70-svn with the following version of libgis: libgis Revision: 62395 libgis Date: 2014-10-26 18:17:27 Thanks for you help.
