What programs can I use to view the PAMAP LiDAR data?
This can vary with the type of PAMAP LiDAR data used. The shapefile contours and breaklines, as well as the GeoTIFF DEMs can readily be utilized in ESRI’s ArcGIS. Extensions such as 3D Analyst, Lidar Explorer 2.0 from ProLogic (http://lidar.prologic-inc.com/lidar/MainPages/LE_Main_Index.html ), and LP360 from QCoherent Software (http://www.qcoherent.com/product.htm), can extend ArcGIS’s capabilities with utilizing LAS file data. A number of free software choices are available. GeoCue (www.geocue.com) offers free downloads of both PointVue LE software, a 3D LiDAR visualization tool which can be used to view LiDAR data in ASPRS LAS Version 1.1 format, and their LAS Reader for ArcGIS 9 extension, which adds LAS Version 1.0 File read capability to the ArcGIS 9 family of products. Merrick & Company (www.merrick.com) offers a free LiDAR viewer called the Mars Viewer (http://www.merrick.com/servicelines/gis/mars.aspx). ESRI offers ArcGIS Explorer software (http://www.esri.com/software/arcgis/
