Also been using this for UK-I found it checked out fine for my location, which i had originally defined using old ordnance survey maps-its the easiest way i have found yet for getting (and checking locations) co-ords-I have a link to mapblast on my website http://www.amos39.f9.co.uk ------- Forwarded message follows ------- Date sent: Mon, 23 Apr 2001 23:12:10 -0500 From: "Tom Wagner" <sciteach1950@home.com> To: "SeeSat" <SeeSat-L@blackadder.lmsal.com> Copies to: "Tom Wag." <sciteach1950@home.com> Subject: Checking your coordinates To anyone in the US that wants to verify the coordinates of their location: I don't know how the rest of you do it but I determined my latitude and longitude here in the States using the data provided by Map Blast at http://www.mapblast.com/myblast/index.mb By clicking on the latitude & longitude shown just above and to the right of the map of my location, a person can switch back and forth between the decimal coordinates and the degrees/minutes/seconds form. I just checked the accuracy of the Map Blast figures against the Digital OrthoPhoto Quadrangle Image information at Microsoft terraserver http://terraserver.homeadvisor.msn.com/default.asp . The info supplied by Map Blast was within a second of arc each way of the USGS image info. Using Terrserver, a person here in the states can find a picture of their house (unless its too new) on one of the photos supplied by the US Geological Survey. To verify your exact coordinates, choose "Image Info" next to the upper left corner of the photo. Typing in the coordinates under "advanced find" will only get you within a couple miles of your location. The only way to actually find your place is to look for it the hard way as you zoom in closer and closer. Using Terraserver a person could locate the exact position of any vacant lot or spot on a country road and so on.
