GeoJSON Coordinates?

由 痞子三分冷 提交于 2019-12-11 09:51:23
问题 I have a GeoJSON file that I am trying to process in order to draw some features on top of google maps. The problem, however, is that the coordinates are not in the conventional latitude/longitude representation, but rather some large six/seven figure numbers. Example: { "type": "FeatureCollection", "features": [ { "type": "Feature", "id": 0, "properties": { "OBJECTID": 1, "YR_BUILT": 1950.0 }, "geometry": { "type": "Polygon", "coordinates": [ [ [ 772796.724674999713898, 2960766

Flutter - Get geocode address from coordinates

由 最后都变了- 提交于 2019-12-11 08:52:18
问题 I've implemented a reliable way of getting user lat,long coordinates in an app I'm creating, but can't seem to turn these coordinates into a placemark. I'd also like to figure out what I need to use to print this data. This is what I'm trying to get this data with: List<Placemark> place = []; void _getPlace() async { List<Placemark> newPlace = await _geolocator.placemarkFromCoordinates(_position.latitude, _position.longitude); print(newPlace); setState(() { place = newPlace; }); } Thanks Edit

HERE Batch Geocoder Accepted but never Finishes

问题 I've been evaluating moving our Mapping and Routing apps to use HERE's Rest API. I've been testing some scenarios to proof it out and one I can't seem to get working correctly is the Batch Geocoding. The submission of the data to Geocode works fine and I do get a valid RequestID back but when I poll for the status of the Batch Job the status always says "accepted" but never seems to change. I am using a developer account that has a 90 day trial. Could there be a limitation due to the type of

Google's GeoCode Convert City, STATE into Latitude Longitude

由 偶尔善良 提交于 2019-12-11 06:07:29
问题 The following code works asynchronously. I only have it set up to convert a City, State into latitude and longitude. That value is then alerted. How can I write a function that actually returns these values? var map; var geocoder; function initialize() { geocoder = new GClientGeocoder(); } // addAddressToMap() is called when the geocoder returns an // answer. It adds a marker to the map with an open info window // showing the nicely formatted version of the address and the country code.

Android 4.1 Geocoder.getLocationFromName() throws IOException: Unable to parse response from server ONLY over 3G

问题 I am using the Geocoder in my android app to resolve a string in to Addresses. The following snippet of code works normally over Wifi, but not over 3G. When over 3G, it throws an IOException: Unable to parse response from server . In other discussions about this, a common answer is that a probable cause is that the Geocoder is used many times/minute, surpassing the threshold, and that causes the service to temporarily throw the exception. The I am sure this is not my case, because I never got
