Determining Latitude and Longitude of Your Site

Mobile Mapping App

If you have adequate reception at your site, you can use your mobile device to determine your site’s coordinates (latitude and longitude).

  1. Open your mapping app (Apple or Google). A blue dot will mark your current location.
  2. Press briefly on the blue dot to drop a pin marker.
  3. Scroll down (Apple Maps) or pull the bottom tab up (Google Maps) to see the latitude and longitude in decimal degrees.
  4. For accuracy, record your coordinates with as many decimal places as possible (six digits is standard, e.g., 39.858663, -75.782880).

Google Maps on a Computer

If you don’t have adequate cellular reception at your site to use the methods above, you can determine your site’s coordinates (latitude and longitude) when you get back to your computer.

  1. Open Google Maps in your browser.
  2. Use the search bar or map tools to move the map until you locate your site.
  3. Click on your site location to drop a map marker.
  4. The site coordinates will be displayed in a pop-up near the bottom of the map.
  5. For accuracy, record your coordinates with as many decimal places as possible (six digits is standard, e.g., 39.858663, -75.782880).

During Site Registration on Monitor My Watershed

If you are sharing your Leaf Pack Network data on the Monitor My Watershed data portal, during the site registration process, you can zoom in on the map, click to place a pin at your deployment location, and the lat/long will be auto-generated. See step-by-step instructions on WikiWatershed.org.
