Zooming to a LAT/LONG.   Its possible to zoom to a particular latitude and longitude by first converting your desired latitude/longitude to decimal degrees.  To convert from degree minutes seconds (ie., 38° 32’ 43”) to decimal degrees (38.54527°) add the degrees plus the minutes divided by 60 plus the seconds divided by 3600 (38 + 32/60 + 43/3600).  Next put the resulting coordinates into the end of the web site address in the URL box using the format below:
  • http://gis.gunnisoncounty.org/stable/mainpage.asp (web address)
  • PLUS: ?xstrt=-106.9264&ystrt=38.5452 (lat/long zoom command)
  • EQUALS: http://gis.gunnisoncounty.org/stable/mainpage.asp?xstrt=-106.9264&ystrt=38.5452
  * Don't forget the minus sign in front of longitude since Gunnison is west of the prime meridian.
