Re: [Qgis-user] lidar visualization in qgis
Dear Vincent thanks for the interest in this discussion. I am not a developer but a qgis user and my intention is only to discuss with other users about those minimal functionalities so that somone who is going to develop a plugin/add core functions has a shared idea of what qgis users expect. So I am not able to discuss about technical questions of what kind of library should be used. However I agree with you about adding the support for PostgreSQL PointCloud support since this is already an available datasource.

Re: [Qgis-user] lidar visualization in qgis
The issue with these tools is that (at least last time I looked), some of these tools can't be used in government or commercial sectors without additional licensing. I wasn't able to use the tools via Processing without obtaining a license from the creator. http://www.cs.unc.edu/~isenburg/lastools/download/LICENSE.txt On Tue, Mar 25, 2014 at 3:36 PM, Gino Pirelli lui...@gmail.com wrote: did you tried LASTools as qgis/processing tool? http://rapidlasso.com/ On 25 March 2014 21:08, antonio valanzano anval...@gmail.com wrote: I would like to start a discussion about the minimal functionalities that a new lidar plugin or a core function should present.

Hi Antonio, You may wish to review this recent discussion on the developer mailing list concerning how to best implement it [0]. I believe there may be a Google Summer of Code project as well [1].
