geojson

问题 I'm making a globe in three.js and will be adding some data layers. All of the layers will be created from geoJSON. I have set it up so that the globe (the first data file, which is of countries) shows up as lines. This uses ThreeGeoJSON. However, I do not want just outlines. I'd like to fill the countries with color. My current project can be seen here: http://bl.ocks.org/jhubley/321232d4ccefefcdc53218fd0adccac5 The code is here: https://gist.github.com/jhubley

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

问题 I'm trying to extract geoJson values and store it to an array and listing array of values in a tableview to show the route in mapview. Here I am using Mapbox for mapview because it supports indoor navigation. Right now I am able to show routes in the mapview directly from geoJson file. But I need to extract values to an array for listing values in a tableview. Here is the code I tried for extracting geoJson value: Struct which I have created for extracting values: struct Collection :

问题 I have some data in this format: Dep Dest geom ---- ---- ----- EDDF KIAD LINESTRING(3.961389 43.583333, 3.968056 43.580.... Which contains flight trajectories. The geom column contains the coordinates in WKT format. It is possible to convert them via the library geomet to GeoJSON format, which I want to do in a new column. In order to do this efficiently with Pandas, I am trying to do: from geomet import wkt import json df = .... #load data to df df['geojson'] = df['geom'].apply(lambda x:

问题 I am using angular-openlayers-directive to build my project. I try to rewrite the example of geojson part cause I will get point information dynamically. So I made the source part of geojson inside instead of loading from json file. However, the position of my code is totally different as I expect. The result suppose to show a point at that coordinate I set. But the point is like at the [0, 0]. If I change the to use loading from the json file, that will work. I have no idea why the

问题 This is the follow up question from here. Given : A geojson file with 3 different geometry types (Point, Polygon, Line) and multiple properties ( AssetType , GeoID , etc.), write each geometry type and its corresponding properties to a single Azure SQL record which uses a Geography-type column. Work so far : I have separate SQL statements that will push the properties alone, then push the Polygon alone into a Geography-type column. But this results in the properties in one record and the

问题 I've looked at other solutions to this, such as: Mongodb: Connection reset by peer Mongodb : AutoReconnect, Connection reset by peer But still have this error. I'm trying to load a large GeoJSON file into MongoDB. Here's my code: https://gist.github.com/mittenchops/6499844 using the iterative json parser here: https://github.com/isagalaev/ijson Here is my error: Traceback (most recent call last): File "upload2mongo.py", line 57, in <module> main(sys.argv) File "upload2mongo.py", line 52, in
