Overpass API Android Example?

由 ∥☆過路亽．° 提交于 2019-12-11 02:06:46
问题 for study we have to develop an Android game which is location based. Currently we use OSMDroid to show the map. There are resources (like wood, stone, ...) which the player has to collect. These resources are currently stored in our backend with hardcoded long/lat and will be added with setMarker onto the current map. To provide this game globally, we want to set the resources dynamically based on the "real" world. So we need different layers from OSM (like forest, sea, ..) to set our

Display Markers, Popups with OpenLayer3

由 自作多情 提交于 2019-12-10 20:10:24
问题 I'm trying to understand how can I display markers/popups on osm map with openlayers3, I have found examples in examples on ol3 web page, but... Is there more examples for coding markers/popups with javascript or jquery, preferably something like this or similar examples. The idea is to mark a building, by clicking on the marker it will popup some info for the building, further more I would like to connect important places from the city to this building (library, restaurants, bus stops, etc).

Android OSM zoom level 19 and above

由 人盡茶涼 提交于 2019-12-10 19:59:57
问题 I'm new to Android Development. I have an application that shows a MapView and I've set a bounding box to restrict the user to only viewing the tiles in a specific area. The issue I have is that I need to zoom in, past level 18. Which I've also been able to do so by setting the max zoom level. However, there aren't any tiles available from the default tile provider for zoom 19 and above I really only require up to 20, 21 max too. Is there a way for me to create my own tiles? Have custom tiles

Using Mapzen tiles with Leaflet

由 牧云@^-^@ 提交于 2019-12-10 15:50:38
问题 My reading of the Leaflet and Mapzen documentations suggest that in order to use a custom tile provider with Leaflet, one needs to do just two things: Specify the tile provider in L.tilelayer(urlTemplateToTileProvider) Set this provider to MapZen var urlTemplateToTileProvider = 'http://tile.mapzen.com/mapzen/vector/v1/all/{z}/{x}/{y}.mvt?api_key=apiKey' However, when I try this I end up with an empty map which then proceeds to display markers etc correctly. And yet a manual test for a

Leaflet OSM: Center mapview on polygon

由 ╄→尐↘猪︶ㄣ 提交于 2019-12-10 13:48:52
问题 I want generate a html file including Leaflet library to show an OpenStreetMap view with a polygon. The polygon on the map should be centered. To do so i followed this discussion, but its still unclear to me, how to center an arbitrary polygon and autozoom it. Autozoom means to me, that the polygon is completly in the visible map excerpt and fills it. As example this would be the desired result: This is my code so far: var map; var ajaxRequest; var plotlist; var plotlayers=[]; function

Open StreetMap Reverse Geocoding

由 寵の児 提交于 2019-12-10 13:16:05
问题 Does anyone know of any open source projects that will allow reverse geocode lookups over Open StreetMap data? I'd prefer not to use an existing hosted webservice such as Nominatim since my dataset is large. 回答1: You can install Nominatim on your own, it can do reverse geocoding pretty well. There is also a Nomiatim instance hosted by MapQuest with a less strict usage policy. 回答2: there is also Gisgraphy that use openstreetmap data and geonames. it got 5 web services (geocoding, reverse

问题 Disclaimer: Any API is NO OPTION for me because of the vast amounts of places I want to process. I know there are plenty of services out there but I'd like to have my own solution Ok, after this is said here my question :) There are platforms like OpenStreetMap and maybe others who are doing very well in bringing the world of maps into the open source community. What I need I have an address located anywhere in the world and I want to compute the latitude and longitude, elevation would be
