<div dir="ltr">Hello Eran,<div>Another possibility is to create DEM files from the LIDAR data, then use GDALDEM to create hillshaded tiles. I'm not exactly clear how to create the DEM files however...</div><div><br></div>
<div>One you have DEM files, I wrote a tool that can create a seamless hillshaded layer for GeoServer, then it is served up to OpenLayers the usual way via GeoServer.</div><div><br></div><div><a href="http://rasternormalizer.codeplex.com/">http://rasternormalizer.codeplex.com/</a><br>
