@Frank and Hermann: Thanks a lot! My other question is as follows:
1) gdal_translate -of AAIGrid a.tif a.asc it creates the following: a.asc (ASC File), a.asc.aux (XML Document), and a (IDL project file)... now to do the reverse i do the following: 2) gdal_translate -of GTiff a.asc a.tif it creates: a.tif (TIF Image) but when i open a.tif with ArcGIS it shows that its statistics are not calculated... Can you tell me how to create the 2) with statistics already computed? So that when i open it in ArcGis for example I do not have to ask ArcGIS to compute the statistics? Thanks a lot! =================================================================== @Joaquim: when the AAIGrid is created its format is of the following form: ncols 250 nrows 398 xllcorner X.Y yllcorner Z.W cellsize 30.863820105342 NODATA_value 255 255 255 255 255 255 255 255 255..... Now, I will be changing the for example this to the following ncols 250 nrows 398 xllcorner X.Y yllcorner Z.W cellsize 30.863820105342 NODATA_value 255 255 255 2 255 1 255 0 255..... (this is only to show my intention...) ========================================================= Best wishes all of you, Riki _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
