Hi,<br>
I am creating a Windows .bat files with a Python script to make DEMs
with LiDAR points. The idea is simple.<br>
1) read input txt file to get the cloud geometries<br>
<br>
2)gdal_grid with nodata value marker set to -32768<br>
<br>
3)gdal_warp with -dstnodata to set the value marker (of grid
created in step 2)<br>
<br>
4)gdal_fillnotdata.py to replace the no data values (of grid created
in step 3)<br>
<br>
5)gdal_warp again with -dstnodata to set the value marker (again as
some values may still be outside of spet 4 search radius)<br>
<br>
6)gdaldem hillshade made with DEM of set 5<br>
<br>
7)gdal_warp again with -t_srs srs_def: to set the CRS of the
Hillshade created in step 6.<br>
<br>
It looks like I am loosing time with gdal_warp (step 3,5 and7) as I
am reading a file, adding novalue data or setting CRS, then writing
the new file and then deleting the old file.<br>
<br>
Question: Is there another way of doing this without steps 3, 5 and
7 or did i get it right? <br>
<br>
Thanks,<br>
Nicolas<br>
P.S.<br>
I am using win7_64 and gdal 1.11.2.<br>
