Finding your graticule

From Geohashing

There are a few ways to find your local graticule. You need to know it in order to find where to go on your expedition, and you should probably bookmark the wiki page for your home graticule because you'll use it to communicate with local geohashers.

If you know your home GPS coordinates

Start by figuring out which graticule you are in. If you already know your home latitude and longitude coordinates, then look at the whole degree portion only. If the latitude is north consider it positive. If the latitude is south, put a minus sign in front of it. Likewise for the longitude. An east longitude is positive and degrees west are negative. For example, I am writing this sitting at N58 48.157 W122 41.335. My current graticule is therefore 58,-122. Note the comma, no space. You can type that right into the search box at left and hit Go. That should redirect you to a page showing the name of that graticule. If it doesn't work, try one of the following methods.

By place name

If you live in or near the largest city around, chances are your graticule is named after that city, or at least named on the graticule page. Try typing the name of the city into the search box at the top of the page and clicking or tapping the magnifying glass, or pressing Return/Enter on your keyboard. Look for a page in the results list that describes the one degree square in which you live. It may be that you are in the next graticule over and can click the links above the map to get there.

The graticule page typically has a map and description of the graticule, a list of local geohashers, and links to previous expeditions. There should also be a today's location link on that page. Click it and it will take you to a map, with a map pin indicating the day's location.

If you can't find the page, or the today's location link is absent, go to the next section.

Using a graticule map

Pick a graticule map to use, then zoom and pan around the world as necessary to find your home. Click on where you are so that a rectangle appears around it. Note the coordinates that GPS receivers uses, plan a safe route, bring anything you'll need, and go!

We all hope to see you at our coordinates someday, and look forward to reading your report when you get back.
