由 青春壹個敷衍的年華 提交于 2019-12-10 10:56:08
问题 I'm trying to query Hotels in a specific area. Unfortunately I need to query nodes and ways, because some Hotels are only stored as way and some as nodes. http://overpass.osm.rambler.ru/cgi/interpreter?data=%28way[tourism~hotel]%28around:5000,50.10707,8.76040%29%29;out; The result of a way-query doesn't contain any coordinates, only lots of node-refs: <nd ref="1438833423"/> Is there a way also to include the coordinates of the nodes in the output or do have to start lots of additional queries

Animating markers on OpenStreet Maps using osmdroid

由 前提是你 提交于 2019-12-09 07:05:12
问题 I'm using the google Maps marker animation logic given here. My marker gets animated,but after each marker.setPosition(newPosition); I need to call mapView.invalidate(); which refreshes the map resulting in very sluggish animation. Is there any workaround? 回答1: The next solution is working correctly for me: import org.osmdroid.api.IGeoPoint; import org.osmdroid.api.IMapController; import org.osmdroid.util.GeoPoint; import org.osmdroid.views.MapView; import org.osmdroid.views.Projection;

Mapbox GL using external maps

由 只谈情不闲聊 提交于 2019-12-09 05:50:53
问题 I want to use Mapbox GL in my Android application. This service is going to be released soon and I have a tricky question about using the renderer. I like the renderer itself, but I really want to use my own maps data in the application (not the data, offered by Mapbox and which is paid). For instance, I want to parse OpenStreetMaps data on my own, customise it somehow and then put inside of a renderer to show it in my application. And now the question: is it possible to use my own maps data

Read cities and streets into a database without api

由 一曲冷凌霜 提交于 2019-12-08 10:49:07
问题 I managed to download and extract an osm-file into a mysql-database, like: osmosis --read-xml myfile.osm --write-apidb dbType="mysql" host="localhost" database="osm" user="osm" What I now need is a way to get only cities and their streets into the database and query them. So how do I limit the data passed from the osm-file to the database to cities and streets? I don't need any additional data. I do not want to use any only APIs or services. 回答1: Osmosis supports so-called data manipulation

Disable scrolling in Osmdroid map

由 纵然是瞬间 提交于 2019-12-08 06:04:00
问题 I have an Osmdroid MapView. Even though I have set mapView.setClickable(false); mapView.setFocusable(false); the map can still be moved around. Is there a simple way to disable all interactions with the map view? 回答1: I've found a solution. You need to handle the touch events directly by setting a OnTouchListener . For example, public class MapViewLayout extends RelativeLayout { private MapView mapView; /** * @see #setDetachedMode(boolean) */ private boolean detachedMode; // implement
