User:Eupeodes/Geohashing Map/v1

This implementation IS FULLY 30W-compliant.

http://gh.eupeodes.nl

Why another one

None of the calculators really worked like I wanted, so I decided to write my own based on the google maps API V3 and geo.crox.

Supported platforms

• Desktop: (all?) modern browsers support on any OS
• iPad: Works very well with multi touch

Not tested

• Android: but for that there is geohashdroid
• Smartphones of any type (but iPhone is expected to work just as good as iPad)

If anyone tests the app on any system, feel free to report if it works, either here (if it works) or on the discussion page (with bug report).

Features

• Uses geolocation to determine location, also possible to provide url parameters or store home in a cookie
  • When no location is provided the map will center on the Netherlands
• Shows hash in home graticule + 8 surrounding graticules
• Download 1 or 9 hashes as gpx
• Select previous date, next date and today with buttons
• Display distance from home to hash in kilometers and miles
• Clear popup message when hashes not yet available
• Link to the meetup on the wiki

Planned features

• Implement send to gps (for at least Garmin, maybe more)
• Display global hash
• More than one day on the map (with different colors/numbers/letters)

Want another feature? Feel free to ask on the discussion page. I don't promise I will do something with it, but I can take it into consideration.

Usage

Parameters:

• lat - latitude of the initial graticule
• lon - longitude of the initial graticule
