can't implement L.mapbox.simplestyle with geoJson

由 一个人想着一个人 提交于 2020-01-06 12:57:44
问题 I'm trying to implement simplestyle's options for marker size and color , but can't get them to render. In this simple test case, I'm trying to follow Mapbox's own example quite closely: var myData = [ { "type": "Feature", "geometry": { "type": "Point", "coordinates": [4.509373,51.932994] }, "properties": { "marker-size": "large", "marker-color": "#ffcc00" } } ]; var map = L.mapbox.map('map', 'examples.map-20v6611k') .setView([51.932994,4.509373], 8); L.geoJson(myData, { style: L.mapbox

Android WebView : disable geo: for addresses

由 巧了我就是萌 提交于 2020-01-04 06:15:52
问题 In my Android application, I am using a WebView to render a list of locations. For some reason, when I click on a list item, it interprets it as a "geo:" address and opens the default browser to show the location. How can I configure the WebView to not interprete the location's addresses. I don't want the "geo:" handling to swallow the "normal" list item touch event. If I tap carefully just on the location name then the "normal" list item touch event is fired. The WevView must interprete

Transforming Data from GeoJSON to SQL Geography

由 两盒软妹~` 提交于 2020-01-03 03:01:06
问题 The basics first, server is MS SQL Server 2016 developer edition, and I'm transforming county shape data that is stored in a NvarChar(max) column as GeoJson to a sql geography field for better storage and spatial indexing. Right now the data is stored as blobs, and I'm trying to optimize storage and create spatial indexes to speed up location comparison (EG: Does X highway intersect with Y county). There is a lot of documentation on going from sql geography data to Geo-JSON, but not so much

Soundcloud api: Geo Tag search not working

问题 Geo search tags appear not to be working. I have an app that has been running for months with no changes. It broke recently and upon troubleshooting I found that geo tag search, both specific and with wild card, returns no results. $(document).ready(function() { SC.initialize({ client_id: 'my id here'}); SC.get("/tracks", {limit: 200, tags: 'geo:lon=-118.*'}, SearchTracks); }); var SearchTracks=function Search (tracks){ for (var key in tracks) {console.log(tracks[key].title+" "+tracks[key]
