Hello all, I've been trying to use the i.image.mosaic command in GRASS 6.4.1 in Ubuntu to stitch two raster image files (technically I'm trying to stitch only the blue channel of an RGB truecolor image) but I'm just getting a blank image file as the output.
I set the region to the proper region and it's not a "NULL" file, but rather, it just doesn't show up. If I use the r.patch command they both patch into one single raster, but unfortunately the colors aren't really balanced. Does anyone know what's up? Here's the output from r.info on the mosaicked image using i.image.mosaic: (Tue Nov 12 17:52:43 2013) r.info map=Warehouse17.blue.georectified.Warehouse18.blue.georectified.mosaic@Warehouse_Mosaic +----------------------------------------------------------------------------+ | Layer: Warehouse17.blue.georectified Date: Tue Nov 12 16:57:08 2013 | | Mapset: Warehouse_Mosaic Login of Creator: user | | Location: Parking_Lot_Test_4_UTM | | DataBase: /home/user/Documents/grassdata | | Title: ( Warehouse17.blue.georectified.Warehouse18.blue.georectified.m | | Timestamp: none | |----------------------------------------------------------------------------| | | | Type of Map: raster Number of Categories: 511 | | Data Type: CELL | | Rows: 5232 | | Columns: 5487 | | Total Cells: 28707984 | | Projection: UTM (zone 17) | | N: 3280373.34673833 S: 3280265.18938071 Res: 0.02067228 | | E: 372335.90758975 W: 372236.78889019 Res: 0.01806428 | | Range of data: min = 0 max = 511 | | | | Data Description: | | generated by r.mapcalc | | | | Comments: | | if(isnull(Warehouse17.blue.georectified), | | Warehouse18.blue.georectified + 256, Warehouse17.blue.georectified) | | i.image.mosaic "image1=Warehouse17.blue.georectified" "image2=Warehouse | | 18.blue.georectified" | | | +----------------------------------------------------------------------------+ (Tue Nov 12 17:52:43 2013) Command finished (0 sec) Thanks, and let me know what you guys think.
