Issue with geolocation timeout callback firing whether response received or not

由 試著忘記壹切 提交于 2019-12-08 09:08:28
I've implemented a timer for a HTML5 geolocation request as per this post Geolocation feedback while accepting the request However I'm having an issue where the timer is called regardless of whether the navigator.geolocation.received response is true or not. Perhaps I'm missing something very obvious but I can't see what. Basically, if I get the geo-location information I run the geo_success_action() function, but in every other case (geo-location failure, timeout on accepting location share, or non-existence of html5 geo-location support in the browser), I want to run the geo_failure_action()

Geohash-Java Search Nearby LatLongs

由 可紊 提交于 2019-12-08 08:19:30
问题 I've been searching everywhere for a clear example of how to use the ch.hsr.geohash to search for nearby locations. I mean, I just need to implement the following situation: 1 - I have a Long latitude and Long longitude. 2 - Convert this latitude/longitude to hash. (I believe it's done by using "GeoHash.withBitPrecision(latitude, longitude, 64)" but I'm not sure what precision is here. I suppose 64bits would be to have the same precision as long 3 - Retrieve a list of latitudes/longitudes

问题 I want to develop one mobile app using cordova/phonegap which will find distance traveled , avg. speed and acceleration for particular fixed time frame say 20 sec. provided by user. I have read that geolocation or accelerometer api of phonegap can be used over there , but I am confused and unable to understand which formula or method to use and how to calculate those values? Please help me to achieve this functionality. 回答1: The Javascript library at the bottom of this page is really useful

How can I capture altitude on an Android phone?

问题 I want to be able to capture altitude in my Android app. I know I can use GPS for where I am, but is there any way I can derive roughly how high the phone is off the ground using a combination of sensors? If not, what is the closest estimation I can get? 回答1: If the phone has a barometric pressure sensor, you can use SensorManager.getAltitude to get the altitude based on a pressure reading. This method also requires the current pressure at sea level, which can either be obtained from local

MySQL GeoSpatial function for ST_Distance_Spheroid? Metric used in return Type of GLength?

由 醉酒当歌 提交于 2019-12-08 06:55:28
Is there a ST_Distance_Sphere, ST_Distance_Spheroid equivalent function in MySQL's GeoSpatial Support? If not, any way to emulate this? What is the metric used in return type of GLength (length of the LineString)? The manual for GLength says that GLength() is a nonstandard name. It corresponds to the OpenGIS Length() function. But I couldn't find any Docs for OpenGIS Length(). All I found was for ST_Length are they the same? Also for accuracy do I need to specify the SRID(4326)? How Do I do this in MySQL? Since MySql 5.1 there are provided GIS functions distance_sphere() and distance_spheroid(

问题 When trying to get geolocation on iPhone the first time - I declined. Every other time I want to get the location (before another reload of the page) I get no response (no error and no success): navigator.geolocation.getCurrentPosition( function (location) { ig_location.lat = location.coords.latitude; ig_location.lng = location.coords.longitude; alert('got it!'); }, function(PositionError) { alert('failed!' + PositionError.message); } ); Is there a way to notify the user every time I fail to
