I have been working in the GIS industry since 1992, with prior programming experience dating to the mid 1980's. Much of my career has focused on topographic sciences, and until recently, the creation and maintenance of the National Elevation Dataset (NED). The heart of NED production was a program dubbed "Assemble", which I initially wrote in C for execution on UNIX platforms, and later completely rewrote in Visual Studio for execution on Windows desktops and servers.Using the NED data in a practical application, I created a robust application for the Federal Aviation Administration that rapidly determined the highest elevations within a user-specified area. It was hosted at USGS/EROS and made available as a web service.I have the dubious distinction of having inspected and reviewed nearly all of the 7.5-minute series digital elevation models (DEMs) produced by the USGS, but also large amounts of elevation data produced by more modern methods, such as lidar and ifsar. Most recently I've tried my hand at producing DEMs myself from aerial photography using Agisoft's Photoscan Professional.Colleagues know me as an all-around problem solver, and I've happy taken on all manner of challenges in GIS, programming, data analysis, and even data compression and storage. I'll often come up with something new, such as the "Squish" algorithm currently under development which combines quadtrees and space-filling curves for the compact and efficient storage of sparse raster data.Feel free to contact me if you'd like to connect.
