This implementation IS FULLY 30W-compliant.

Please double check the output - it's been tested but ...

This calculator creates a KML file.

If you install Google Earth or other applications such as Marble that understand this file format, it should launch and display the hashpoints for your specified date and graticule.

Usage

Use this input form or modify the web address below ...

http://nbest.co.uk/kmlGeohash/index.php?date=2008-05-21&lat=52&lon=0&skins=2

If any URL parameter is omitted, a default value is used instead.

• date - formatted yyyy-mm-dd - the default is today's date - alternatively try for example, 1 for tomorrow or -2 for the day before yesterday.
• lat - your graticule latitude - the default is 51 (Grenwich London).
• lon - your graticule longitude - the default is 0 (Grenwich London).
• skins - like an onion, the number of layers of points surrounding the home point - the default is 1 giving 9 hashpoints - the limits are 0 to 6.
• debug - check this or add '&debug=debug' to expose the guts of the algorithm.

Bugs and feature requests

Please put bug reports and feature requests on the discussion tab.

• Google earth street view is very useful if your country allows this.
• UK geohashers will like the Bing Map (UK OS) link. This shows the hashpoint and rights of way for access.
