Re: Pls help: extract LIDAR data from .all files

thanks anyway. The guy is on leave for long and I can't get hold of him.

Here is some general advice. LIDAR data is
supplied to clients as a cloud of X, Y, Z
coordinates. There is no standard format for
such data.

The data are often presented as columns in
plain text files or as spread*** files. A
search on the Web showed that Lotus 1-2-3
spread*** files use the extension ".all",
so I suggested you try to read a file using
the Excel spread*** program. I don't know
whether Excel can read Lotus 1-2-3 files.
Maybe you can find a copy of Lotus 1-2-3
somewhere and try that.

Sometimes, in addition to the X, Y, Z cloud,
the client is supplied with a raster grid.
This is derived from the cloud and, hopefully,
is geo-corrected. GeoTIFF files are popular
for this. However, the ".all" extension
doesn't fit well here.
