The PSAP for my area does not - last time I was there - have the direct ability to handle cell phone delivered GPS coordinates. They use Google Maps (really) if they have coordinates available, but the CAD system simply can't handle that data input so (last I heard) it was ignored.This is a known issue and it's been over a year since I last asked about it, but it was definitely a problem, especially along the river which is the border between two states and cell sites pick up across borders.
