Managing West Nile virus with GIS; monitoring mobile assets with FleetScape

If you’re one of the 359,000 people living in Ada County, Idaho (2006 population estimate according to http://quickfacts.census.gov), you can feel the sting of the West Nile virus. According to the Idaho Department of Health and Welfare, "in 2006 Idaho led the nation in reports of human illness associated with West Nile virus, with 996 cases being reported to the state health department. In addition to people, West Nile virus was also detected in 338 horses, 127 birds, and numerous mosquitoes" (http://www.healthandwelfare.idaho.gov).

Like any concerned resident, you’re probably keeping a close eye on the ponds and rivers in your neighborhood. If you happen to find a suspicious-looking cluster of larvae, you can request a mosquito inspection by visiting the Ada County Mosquito Abatement District’s home page. You fill out an online form, enter your address, and then hit the Submit button. What you probably don’t know is, once you’ve done that, your request is geocoded in the County’s GIS database. For the efficiency of this setup, you can thank Jacob Mundt, GIS/mapping coordinator for Ada County Weed, Pest, and Mosquito Abatement District (WPMAD), and his colleagues.

The Bug Squad
As a graduate student of Idaho State University, Mundt studied the effects of noxious weeds. His graduate thesis was on remotely detecting and testing the harmful species. When he joined the WPMAD, he turned his combat skills against the insects that had been causing a buzz. Read more>>


Cad Clinic: Harness Google Earth Tools in Civil 3D 2008, Part 1

By Mike Choquette

For years, the Internet powerhouse Google has collected and served geospatial data from all over the world. This massive library of street mapping, satellite and aerial photographs, digital terrain model data, and more is available for browsing through a free utility called Google Earth. Although Google Earth is similar to other online mapping systems such as Microsoft's Virtual Earth, there is one big difference -- Civil 3D 2008 can import terrain and image data directly from Google Earth, as well as publish its own 3D data for viewing within the Google Earth utility. Some of these tools were available in the Technology Preview Google Earth extension for Civil 3D 2007, but the under-the-hood functionality in 2008 has matured quite a bit. Everyone who uses Civil 3D should be familiar with this extremely useful feature set. Read more>>
