PE&RS February 2005

Cover Image

This month’s cover image is provided by NIIRS10, the Madison, Alabama based company that has developed GeoCue, a family of geospatial workflow management tools. The cover images are a series of views of a large county-wide lidar project being managed in GeoCue. The background image portrays the lidar strips outlined with their true ground footprint. The upper left image (with smaller inset) shows the project partitioned into 975 lidar “working segments” of approximately 1.5 million points each superimposed on a lidar“ Ortho” backdrop. The center inset demonstrates using the lidar ortho for coverage analysis by rendering void areas as transparent and viewing the image superimposed on a red backdrop. Note that gaps between adjacent flight strips are clearly visible. The lower inset shows the utility of visualizing voids caused by water body mirror effect by superimposing the lidar ortho over EarthSat’s NaturalVue LANDSAT data. These tools provide enterprise (multi-user) management of large projects, significantly reducing the time spent in analysis and production management. The March issue of PE&RS will include an in-depth GeoCue product family article.
