google.maps.Geocoder.geocode() geometry.location lat/lng property names change frequently

由 此生再无相见时 提交于 2019-11-27 01:23:40
I have an application, and I'm using the Google Javascript Geocoding API to fetch lat/lng for an address. The code goes something like geocoder = new google.maps.Geocoder() geocoder.geocode({ 'address': query }, function(results, status) { addresses = {}; $.each(results, function(index, value){ addresses[index] = {"lat":value.geometry.location.$a,"lng":value.geometry.location.ab} }) }); All is fine and dandy, but the thing is that the property names of the location object periodically change. Each time they change, my site breaks. Twice I've had to change my code to accommodate the weird lat

Bearing from one coordinate to another

由 喜欢而已 提交于 2019-11-27 01:22:10
问题 I implemented the "bearing" formula from http://www.movable-type.co.uk/scripts/latlong.html. But it seems highly inaccurate - I suspect some mistakes in my implementation. Could you help me with finding it? My code is below: protected static double bearing(double lat1, double lon1, double lat2, double lon2){ double longDiff= lon2-lon1; double y = Math.sin(longDiff)*Math.cos(lat2); double x = Math.cos(lat1)*Math.sin(lat2)-Math.sin(lat1)*Math.cos(lat2)*Math.cos(longDiff); return Math.toDegrees(

How does IP geolocating work?

由 主宰稳场 提交于 2019-11-27 01:00:46
问题 I'm not looking for a service that does this. I'm just curious as to how geolocation works. 回答1: Mapping IP addresses to geolocations is done via tables, where an IP maps to a particular location. This location, however, does't need to be accurate, since IP addresses don't carry any information about their locations, these are approximated . From http://en.wikipedia.org/wiki/Geolocation_software: The primary source for IP address data is the regional Internet registries which allocate and

Which Devices Support Javascript Geolocation via navigator.geolocation?

由 送分小仙女□ 提交于 2019-11-27 00:23:17
The iPhone supports geolocation in mobile Safari via the following call: navigator.geolocation.getCurrentPosition( function(pos){ var lat = pos.coords.latitude; var long = pos.coords.longitude; }, function(){ /* Handler if location could not be found */ } ); I'd like to build a good list of devices that have one of the following: support this feature out of the box , or support this feature with an upgrade, or support geolocation with equivalent fidelity of data with some other snippet of Javascript. I'm only familiar with my own device, so this is my list so far: Out of the box: iPhone 3GS

Converting latitude and longitude to decimal values

由 旧街凉风 提交于 2019-11-27 00:06:26
I have GPS information presented in the form: 36°57'9" N 110°4'21" W I can use the javascript functions of Chris Veness to convert degrees, minutes and seconds to numeric degrees, but first need to parse the GPS info into the individual latitude and longitude strings (with NSEW suffixes). I have read related posts on stackoverflow, but am not a regex expert (nor a programmer) and need some help with the parsing function. What's the best way to parse this string into latitude and longitude for use in the conversion function? The result of all this will be a Web link that one can click on to see
