I have LiDAR files in two ESRI formats and don't know which would be the<br>
better one to use: .shp and .adf.<br>
<br>
My research taught me that .adf is Amiga Data File, and I thought that<br>
Amiga died several decades ago. Seems that ESRI is using that format for<br>
some reason and it does not appear to be supported by gdal.<br>
<br>
The directories with the adf files also contain .dat, .nit, and .dir<br>
files and come in three versions: bare earth, highest hits, and intensity.<br>
<br>
My use of these DEMs is for hydrological modeling, including storm runoff<br>
with times of concentration for specified 24-hour storm hydrographs. So, I<br>
want to become informed about my choices. Recommended readings also<br>
appreciated.<br>
<br>
Regards,<br>
