[gdal-dev] LAS support
Hello everyone, Is there any interest in having LAS as one of the OGR supported formats? Would there be any particular reason for not supporting it? I would be willing to collaborate on this effort, if deemed useful. Regards, Rui ___ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev

Re: [gdal-dev] How to get GDAL
- From there I've tried both the msi (plus python bindings extra) and the zip Compiled binaries in a single .zip package- both work for the pure-GDAL stuff (gdalinfo) but none of the python scripts works (i.e. gdal_merge.py). I prefer the zip version, expand it to a folder of my choice, and run the SDKshell.bat. In the command window I can do the things I want to do in GDAL, without any interfering of other programms, even not from QGIS. Inside the shell, all varaibles are set correctly, and therefore all python modules run too. And it is no problem installing an experimental new GDAL version and keeping the old one in parallel. That would be my preferred option, but as noted, the python stuff doesn't work. I was getting a python error whenever I tried to run them. Fortunately the OSGeo4W version works fine.

-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Rui, IMHO point clouds are special form of vector data. But still, an OGR driver would not be a viable solution. Did you have a look at PDAL (http://www.pointcloud.org/)?

Re: [gdal-dev] LAS support
IMHO point clouds are special form of vector data. But still, an OGR driver would not be a viable solution. ... or as already mentioned of rasters (or grids as I prefer to call them when they are so). By accident I found that that grids stored as XYZ in laszip are 3 times smaller than the same grid in netCDF with a deflation level of 9 (the maximum). That makes it a REALLY interesting grid storage format. Joaquim Did you have a look at PDAL (http://www.pointcloud.org/)?

[gdal-dev] .csvt file doesn't allow space after comma
I am trying to use a .csv file in a qgis project. After not getting what I expected, I learned about .csvt files and wrote a file that looked like "String", "Integer" with a space following the comma. This did not work - both fields were still read as String. After removing the comma I got a String field and an Integer field. The documentation states the list is comma-separated, which I suppose if strictly interpreted could mean no white space. However, in general .csv files ignore whitespace following a comma. I'm posting this in the event that someone is working with a more complex .csvt file that fails might have a chance of finding this when they search for a clue as to why their file isn't working. ___ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
