$ v.info map=utm10_3132 [...] | Number of points: 0 Number of areas: 43280 | | Number of lines: 0 Number of islands: 1 | | Number of boundaries: 87166 Number of faces: 0 | | Number of centroids: 43280 Number of kernels: 0 | [...] | Projection: Lat/Lon | | N: 72:05:57.201093N S: 27:05:25.520375N | | E: 12E W: 0 | $ v.info map=utm10_3334 | Number of points: 0 Number of areas: 43280 | | Number of lines: 0 Number of islands: 1 | | Number of boundaries: 87174 Number of faces: 0 | | Number of centroids: 43280 Number of kernels: 0 | | Projection: Lat/Lon | | N: 72:05:57.201093N S: 27:05:25.520375N | | E: 24E W: 12E | $ v.info map=utm10_31to34 # patched map | Number of points: 0 Number of areas: 85544 | | Number of lines: 0 Number of islands: 0 | | Number of boundaries: 174340 Number of faces: 0 | | Number of centroids: 86560 Number of kernels: 0 | | Projection: Lat/Lon | | N: 72:05:57.201093N S: 27:05:25.520375N | | E: 24E W: 0 | So, both input maps have the same number of polygons and centroids (as expected), but different number of boundaries - is this normal? The original maps were shapefiles that I imported with v.in.ogr. Should I do any additional cleaning of topology? Also he two inputs have an island each, but the output has none. The geographic limits are as expected for two longitudinally adjacent tiles. And the output has the sum of the number of centroids of the two inputs, but less areas...
