User-Created
Google Maps
The
following links point to various Google Maps I have created. Most of them are designed for use with a GPS
after conversion to one of several supported GPS formats for point-of-interest
(POI) files:
Public
Safety Locations
Long
Island Maps
Weather
Radio Maps
Retrieving Longitude
and Latitude from Google and Bing Maps
During
the development of the above maps, there were times when obtaining the latitude
and longitude of a specific location was a necessity. Latitude and longitude make it easy to move
back and forth between Google Maps and Bing Maps. Google and Bing each have various ways of
interpreting coordinates presented to them but both respond to coordinates
presented in NSEW format using positive numbers. As such, I developed two Javascript
URL’s, one for Bing and one for Google, that will present me with a prompt box
containing the latitude and longitude of the center of the map. In order to find the location of a specific
point on a map, one needs to center the map on the desired point and then enter
one of the following URL’s to get the location of the point:
For
Google:
javascript:c=gApplication.getMap().getCenter();lat=c.lat();lon=c.lng();void(prompt('Coordinates:%20Latitude%20and%20Longitude',(lat<0?-lat+'S%20':lat+'N%20')+(lon<0?-lon+'W':lon+'E')));
For
Bing:
javascript:c=map.GetCenter();lat=c.latitude;lon=c.longitude;void(prompt('Coordinates:%20Latitude%20and%20Longitude',(lat<0?-lat+'S%20':lat+'N%20')+(lon<0?-lon+'W':lon+'E')));
The
easiest way to use these URL’s is to create a bookmark for each one. Then the appropriate URL can be called when
needed from the list of bookmarks.
For
the really adventurous, a single bookmark can be setup to use the following
code which will work for both Bing Maps and Google Maps:
javascript:if(typeof(gApplication)=="undefined"){c=map.GetCenter();lat=c.latitude;lon=c.longitude;}else{c=gApplication.getMap().getCenter();lat=c.lat();lon=c.lng();};void(prompt('Coordinates:%20Latitude%20and%20Longitude',(lat<0?-lat+'S%20':lat+'N%20')+(lon<0?-lon+'W':lon+'E')));
Search Google Maps
Recently, Google removed the ability to search their site for
user-created maps. The functionality is
still available but there is no method on the Google web site to access the
feature. This form will allow you to
search Google Maps for user-created maps.
Note that your search will open in a new window/tab.
NOTE:
Google appears to have disabled the hidden search functionality. This form may or may not work!
