[GRASS-user] r.contour generates no lines
Hi, I tried to create contours from a DEM with the following information: | Type of Map: raster Number of Categories: 255 | Data Type:FCELL | Rows: 9856 | Columns: 4844 | Total Cells: 47742464 |Projection: Transverse Mercator |N: -3704977.57894189S: -3803537.57894189 Res:10 |E: -15589.63705055W: -64029.63705055 Res:10 | Range of data:min = -39.681747 max = 1084.584839 The command I used was: r.contour --overwrite input=ct_dem_...@permanent output=ct_contours_1...@permanent step=100 cut=2000 However, the resulting vector file contains no lines. This is the output of v.info: | Type of Map: vector (level: 2) | | Number of points: 0 Number of areas: 0 | Number of lines:0 Number of islands:0 | Number of boundaries: 0 Number of faces: 0 | Number of centroids:0 Number of kernels:0 | | Map is 3D: Yes | Number of dblinks: 1 | | Projection: Transverse Mercator | N: 0S: 0 | E: 0W: 0 | B: 0T: 0 The attribute table does contain 10 categories starting from 100m and ending at 1000m. Leaving out the cut parameter doesn't change anything. Any ideas about why the file contains no features?
