UTM interface to Google maps

lat/lon, UTM or MTM to Google maps interface

The conversion application on its own with short instructions (below). See utmgoogle.htm for full usage notes, and utmgoogleappQC.htm for a version supporting MTM for Quebec only.

Select ellipsoid:
Traverse Mercator:	UTM MTM Canada MTM ref meridian: (see notes)
Latitude (dms)
Longitude (dms)
xTM Eastings
xTM Northings
xTM Zone
Display with:	Google map NRCan topo map USGS topo map
Display window:	here separate

Computed values (for cut&paste):

lon dec:
xTM:
lat/lon:

Usage in short:

Select a different ellipsoid if needed.
Select UTM or MTM if you are interested in the conversion or inputting of UTM or MTM data. MTM is for Canada only. If using MTM, you can specify an explicit reference meridian (otherwise, leave blank). See here for some extra notes on MTM.
Enter geographic coordinates in either lat/lon group, or in easting/northing/zone (xTM) group.
- Lat/lon: accepts various formats: "[+|-] deg [min [sec]]", spaces and non numeric characters are ignored. If no sign is used, then set the N/S and W/E fields to the right as appropriate (defaults to North America). Eg.
  · 45° 30' 43.8" (needs explicit N)
  · + 45 30.73 (implicit N)
  · -73.54574 (implicit W)
- xTM group: enter the values in meters (no spaces or letters), specify the zone number (gore), and, for UTM, the zone letter.
If you wish to display the location, select display options (map, window).
Click the "Calculate" (convert) or "Display" button of the group where you entered your geographic data. In both cases, the cut-and-paste fields at the bottom will be updated.

There is also a bulk xTM to lat/lon conversion tool on the full page.
