LIDAR Analyst 4.2 Released

Version 4.2 of LIDAR Analyst was released today for the ArcGIS platform.

The biggest new feature is the ability to process your LIDAR tiles in batch. The implementation itself is unique and similar to the way in which batch is implemented for Feature Analyst. You first run through your extraction for one tile which is representative of all the other tiles that you wish to process as a batch. As you run through the extraction manually - all your custom settings are stored to a model file. You then launch the Batch Processing dialog, specify the model file, set all the input tiles and start the extraction process. You can then go home, take a coffee break or whatever - depending on the size and number of tiles - after a while you will have a folder hierarchy of your extracted results. As simple as that!

Some of the other exciting new features that we added are - an export to Google Earth (KML) command and an Extract Contours command. The API was also improved as well as many of the underlying algorithms, etc - which should allow you to process data-sets with better accuracy and higher speeds.

Below is the Press release:
