Geo Hashing:Coordinate calculators
From Geo Hashing
A coordinate calculator is any tool which can perform the geohashing algorithm. There are many different implementations of calculators, but there are a couple which get the majority of use.

[edit] Peeron Maps
This is the original implementation, and the one used most often by geohashers. It offers an easy to use interface based on Google maps.
[edit] Basic Usage
- Pan the map around, and click on the location you wish to geohash in.
- Ensure the date in the entry box, which is in the lower left corner, is correct for the day you wish to geohash on, and hit the Update button.
- The coordinates are provided in the lower right corner in three formats, all of which describe the same location.
- ddd.dddddd, ddd.dddddd
- ddd mm.mmmm, ddd mm.mmmm
- ddd mm ss.ss, ddd mm ss.ss
[edit] Other Useful Things
- If you wish to have the currently selected region, known as a graticule, be your default for each time navigate to the page, click the Set Default button. Cookies must be enabled for this to work.
- Below the date entry box, there are various different helpful links:
- Link to this page: This is a link to bring up the page you are currently looking at, including the selected graticule and date.
- Google map: This shows the current hashpoint on the standard Google maps. This is useful for getting driving directions to the nearest point on a road.
- Nearby food: Because eating is often a fun activity to do with people you met a geohash, especially if it is a location you can't stick around at for too long.
- Day: A link to the date page on the wiki for the date you selected.
- Meetup: A link to the expedition or planning page for the graticule and date combination you selected.
- Graticule Name: This will take you to the page corresponding to the graticule you selected. The text of this link will vary based on the graticule you have selected.
[edit] Small Hash Inquiry Tool (a.k.a. anthill)
Ekorren created this tool out of a desire to have something which perfectly suited his needs. As it turns out, many people found out they have similar needs to Ekorren, and started using his tool. It is a little more complex to use than the Peeron tool, but provides some very useful added functionality.
[edit] Basic Usage
- Fill in your actual latitude and longitude in ddd.dddddd format. Use '-' for South or West.
- Click the Go button.
- Your current graticule will be shown as the center of the 9 maps, and each of the surrounding graticules will be shown in their relative positions.
- Below the map images, there is some useful information:
- A link to the wiki page for that graticule
- The coordinates in ddd mm.mmm format
- A straight-line distance to the point from the coordinates you entered
- Links to the point on Google, and Open Street Maps (OSM)
[edit] Other Useful Things
See the tool's page for more information on usage and features of this rather feature-rich calculator.
