hi all I have been able to import a dgn file into grass using the v.in.ogr but I have all the point, line and poly features in the same layer. Next When i use v.what then I get a attribute listing which I can't quite understand Anyone who can help me out with - how to seperate the point , lines and polys into three different layers. Also if possible there could be different things represented as lines - roads and rivers both are line features. So how to extract these from the .dgn file into two different layers. I am attaching the output of v.what command for ease of anyone who wishes to help me out. Output of Grass v.what command :-
East: -21786.9555969 North: -23164.1739966 Map: nkd Mapset: PERMANENT Point Layer: 1 Category: 9362 driver: dbf database: /ramdisk/grass/locations/43p/PERMANENT/dbf/ table: nkd key column: cat cat : 9362 Type : 17 Level : 3 GraphicGro : 0 ColorIndex : 0 Weight : 1 Style : 0 EntityNum : MSLink : Text : Paswal When I try to see the layers in the .dgn file using the option list available layers in the dataset and exit from v.in.ogr I get the output Data source contains 1 layers: elements But I think the data source contains more than one layer - atleast one line, one point and one poly for sure. What is the meaning of the above output..... Thanks in advance. Nishith
