I am trying to read in multiple (hundreds, thousand) LiDAR ascii files into Grass. They contain elevation data. I think I have managed one, and I can make a map of elevations, using File, Import Raster Map, Multiple formats using GDAL. The format is as follows:
ncols 1000 nrows 1000 xllcorner 562000.000 yllcorner 7124000.000 cellsize 1 nodata_value -9999.0 108.93 108.92 108.97 108.99 109 109.01... ... ...
1000 lines, 1000 columns, representing 1 sq km with values at every 1 m. Files are called
572000-7144000_dem_1m.asc 572000-7145000_dem_1m.asc 572000-7146000_dem_1m.asc
My question is, how do Y read in multiple files? I have tried concatenating them, no luck.
Thank you for your help.. regards, Szilard
