由 笑着哭i 提交于 2020-01-03 04:52:11
问题 I have a table in MySQL db which two of it's columns are the latitude and the longitude of a given geo-point. it's defined as Float(2,6). I want to select only the records within a specific radius from a given point. I found the following code in Java, that checks the distance between to geo-points: public class Location { private int latitudeE6; private int longitudeE6; ... } public static double CalculateDistance(Location StartP, Location EndP) { double lat1 = StartP.getLatitudeE6()/1E6;

Localstorage my geolocation

由 删除回忆录丶 提交于 2020-01-03 02:55:10
问题 I want to make an app which gets my coördinates and shows them in google maps (using phonegap and testing on emulator 2.2). Then stores those coördinates in localstorage. I have never used localstorage before so i am not sure on how to do this. I got the geolocation part working. If anyone could adjust my code or show a tutorial which explains how to save the lat/long that i will retreive as i don't have a lot of experience using web-langauges. It would be greatly appreciated. <!DOCTYPE HTML

由 只谈情不闲聊 提交于 2020-01-03 02:21:14
问题 I know the formular for conversion from Degree to Milliseconds and vice-versa. It can be implemented like that: protected function decimal_to_milisecond($dec) { if (!empty($dec)) { $vars = explode(".",$dec); if (count($vars) == 2) { $deg = $vars[0]; $tempma = "0.".$vars[1]; $tempma = $tempma * 3600; $min = floor($tempma / 60); $sec = $tempma - ($min*60); return round((((($deg * 60) + $min) * 60 + $sec) * 1000)); } else return false; } else return false; } function milisecond_to_decimal($sec)

iOS 5 Region Monitoring: Can new regions be created based on users current coordinates from coreLocation?

由 风格不统一 提交于 2020-01-02 18:24:12
问题 My question is regarding the creation of regions for regionMonitoring in iOS 5. Can new regions be created based on user of the app's current location? Or do all regions need to be predefined by the developer in the applications binary? I know you can have certain regions register based on the users current location, because the os puts a limit on the number of regions that the phone/app can be monitoring at one time, and you should only register the regions within close proximity to the

由 自闭症网瘾萝莉.ら 提交于 2020-01-02 17:39:12
问题 I have a array of point with latitude and longitude. Next, I add all points to my map. I need solution/algorithm to move user to the nearest point from my array using geoloation on page load.

I combined both HTML5 geolocation to find the user's current location and Haversine function to calculate distances from a set of locations and the user's current location. The set of locations is defined in the JS array 'locations'. <

问题 So, I am trying to develop an application that will display user listings. The site should detect user location (I am using maxmind api for that) and then show listsings from user's location + cities within a user-specified radius. How do I do this? MaxMind API lets me detect user's city by IP address but how do I find nearby cities? Reference site: www.oodle.com (you can also manually change city+radius). Sanguine 回答1: Rather than store and compare cities, store and compare latitudes and
