Hi Everyone, I'm using GRASS 6.4.0/6.4.1 on Ubuntu Lucid to orthorectify aerial imagery. When I try to export the orthorectified images using r.out.gdal, every pixel gets NoData value, whereas the image displays perfectly in GRASS. For some strange reason it was working last week. Then I included the unstable ubuntugis repository (http://ppa.launchpad.net/ubuntugis/ubuntugis-unstable/ubuntu) and installed qgis. I probably installed some updates coming from this repo, including gdal-bin and GRASS. I tried to remove qgis and ubuntugis-unstable and reinstall GRASS, but I just can't get it to export any of the raster maps. I tried to export my images in both 6.4.1 and 6.4.0 without success. I use the following command (tried explicitly defining file type (byte) and nodata value (255) as well, nothing worked): r.out.gdal -c input=FIM90271_0008blue.ortho@PERMANENT output=blue.tif
the metadata of the input raster map: Type of Map: raster Number of Categories: 241 | Data Type:CELL | Rows:15181 | Columns:15348 | Total Cells:232997988 | Projection: Transverse Mercator | N: 6734134.5 S: 6726544 Res: 0.5 | E: 3352185.5 W: 3344511.5 Res: 0.5 | Range of data: min = 0 max = 241 Data Description: | generated by i.photo.rectify Comments: | i.photo.rectify -a group="FIM90271_0008" extension=".ortho" resolution=0.500000 memory=1000 method="nearest" The same problem appears with WinGrass 6.4.1. Could someone enlighten me what might be the problem? Thanks a lot in advance!
