<div>Hello,</div><div>It is my very first attempt to use Grass. Or any other Gis program for that matter.</div><div>I am trying to read in multiple (hundreds, thousand) LiDAR ascii files into Grass. They contain elevation data. </div>
<div>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:</div><div><br></div><div>ncols 1000</div><div>nrows 1000</div>
<div>xllcorner 562000.000</div><div>yllcorner 7124000.000</div><div>cellsize 1</div><div>nodata_value -9999.0</div><div>108.93 108.92 108.97 108.99 109 109.01...</div><div>...</div><div>...</div><div>1000 lines, 1000 columns, representing 1 sq km with values at every 1 m. Files are called</div>
<div><br></div><div>572000-7144000_dem_1m.asc</div><div>572000-7145000_dem_1m.asc</div><div>572000-7146000_dem_1m.asc</div><div>etc.</div><div><br></div><div>Can this data be loaded as is, or it needs to be converted to a format where</div>
<div>X Y Z are columns 1, 2, 3 etc.. </div><div><br></div><div>My question is, how do Y read in multiple files? I have tried concatenating them, no luck.</div><div><br></div><div>Thank you for your help.. </div><div>regards, </div>
