The state of Oregon commissioned a private company to map the service boundaries of the 911 public safety answering points (PSAP) and create a Google Earth data file, and it’s now posted on-line for download. Oregon law requires that each county have just a single PSAP, unless the county can justify more than one. So, the map file turns out to be pretty simple–county boundaries with one or two dots. However, it’s still an interesting datafile, since it includes PSAP names, telephone numbers and other information. Download the .kml format file here, then use Google Earth to open the file and display the map. (Do other states have similar files/maps?)
