geolocation

问题 I am having problems with GPS detection over Google Maps in Ionic App. When I start the App with GPS off and later I change from Settings device to GPS on, clicking by Find Me button - centerOnMe() function - the GPS is not working. The function responses always `Error: GPS Timeout! ERROR = 3` At the beginning I thought that was a cache problem but I have found out that is not that. It doesn´t matter the using $state.reload from the view. ¿does anyone get the same issue? Thanks for the

问题 I am using openlayers 5 to implement a simple geolocation functionality : When check the geolocation checkbox, the geolocation starts, zooms to the position with an animated transition and it automatically tracks the position constantly. It adds a feature in a vector layer. When uncheck the geolocation checkbox, the geolocation is turned off, along with the tracking and that vector layer is cleared. My problem is that I don't know how to wait until the geolocation has a value , so I can

问题 where can I get a list of that? I need the coords of the distrits and cantons of Costa Rica, is there a place to get those? thanks in advance 回答1: geonames.org is a public database of all cities/towns with a population over 1000. The data for each city includes geo coordinates and administrative division, which I believe would be your districts, provinces or cantons. 回答2: Check out the Costa Rica link here - it may suit your needs. I found it with this search: http://www.bing.com/search?q=

问题 I've got a test app that fetches lat/lng values from the HTML5 geolocation service. Unfortunately, it's firing at rather inconsistent time intervals, anywhere from 500ms to 10000ms. I've tried changing the maximimAge and timeout parameters for the watch but those don't seem to change anything. I'm testing it in Chrome as well as via a simple Cordova app on an Android Lollipop build. The code below simply displays the timestamp value of the watch to eliminate any other delays that could be

问题 I have a documents contains list of location "boxes" (square area). Each box is represented by 2 points (bottom-left or south-west, top-right or north-east). Document, for example: { locations: [ [[bottom,left],[top,right]], [[bottom,left],[top,right]], [[bottom,left],[top,right]] ] } I'm using 2d index for those boundaries points. My input is a specific location point [x,y] and I want to fetch all documents that have at list one box that this point is located in it. Is there any geospatial
