Like:</p> <ul> <li>Firefox supports GeoLocation (which varies in accuracy, but is really accurate for me)</li> <li>Stephen Hood released the <a href="http://blockchalk.com/developers">Blockchalk API</a></li> <li><a href="http://twitter.com/joshu/status/3679085168">Google Maps lets you use GeoRSS feeds as a term</a></li> </ul> <p>This solves the problem I had with BlockChalk, which is I wanted a way that I could see what's going on near where I am - and I don't have an iPhone.</p> <p>So I wrote two bookmarklets:</p> <p><a href="javascript:navigator.geolocation.getCurrentPosition(function(p){window.location='http://maps.google.com/maps?q=http://blockchalk.com/api/v0.6/chalks/'+p.coords.latitude+','+p.coords.longitude;})">Blockchalk Me</a> which will list Blockchalk listings near you</p> <p>and</p> <p><a href="javascript:c=gApplication.getMap().getCenter();window.location=%22http://maps.google.com/maps?q=http://blockchalk.com/api/v0.6/chalks/%22+c.lat()+%22,%22+c.lng()">Blockchalk this Google Map</a> which only works if Google Maps is open. It will load Blockchalks that are near the center of the open Google Map.</p> <p>Unfortunately Blockchalk doesn't have a lot of data yet, and will return no results if there's nothing within a mile radius. Hopefully a radius parameter will be included for the API call.</p> <p>So there's no guarantees on the first bookmarklet, but the second bookmarklet should yield nice results for <a href="http://maps.google.com/maps?q=37.74339,-122.428924">this location</a>.</p> <p>Enjoy.</p>
