geojson

问题 I've a massive geo json in this form: {'features': [{'properties': {'MARKET': 'Albany', 'geometry': {'coordinates': [[[-74.264948, 42.419877, 0], [-74.262041, 42.425856, 0], [-74.261175, 42.427631, 0], [-74.260384, 42.429253, 0]]], 'type': 'Polygon'}}}, {'properties': {'MARKET': 'Albany', 'geometry': {'coordinates': [[[-73.929627, 42.078788, 0], [-73.929114, 42.081658, 0]]], 'type': 'Polygon'}}}, {'properties': {'MARKET': 'Albuquerque', 'geometry': {'coordinates': [[[-74.769198, 43.114089, 0]

问题 I am trying to plot individual data points and also a line path that runs between these points like this example D3 stop and restart transition along path to allow click through to geo data coordinates that I have been helped with before. Now I want to use my actual data rather than a test set of coordinates but am running into trouble. I have tried both a geoJson file and also csv for my data. I am using a csv file with lon and lat for the points and was hoping to make the line from that

问题 I have extracted models of some PostGis layers with sequelize-auto, giving: module.exports = function(sequelize, DataTypes) { return sequelize.define('table', { id: { type: DataTypes.INTEGER, allowNull: false, primaryKey: true, autoIncrement: true }, geom: { type: DataTypes.GEOMETRY('POINT', 4326), allowNull: true, }, ... On GET sequelize sends the geom to the client as GeoJSON: { "type":"Point", "coordinates":[11.92164103734465,57.67219297300486] } When I try to save this back PosGis errors

问题 I have a google map that loads markers from a GeoJSON file that runs on localhost in Visual Studio 2013. It also runs in chrome (from an IIS server) but will not run in IE version 11. The map shows up, but the markers from the JSON file do not. Why would this work in Chrome on IIS 8, and IE 11 through VS, but not IE 11 on IIS 8? var map; var infowindow = new google.maps.InfoWindow({ }); function initialize() { map = new google.maps.Map(document.getElementById('googleMap'), { center: new

问题 Problem: I'm attempting to create an interactive map of the US in which state, county and national boundaries are displayed. Counties are shaded based on data, and hovering over a state should highlight all counties in the state, and the state should be clickable. I want to achieve this by having a SVG with the county shapes inside of state shapes, inside of a US shape. I can generate a county map based on a CENSUS county shape file, and I can shade the states based on data in an external CSV

问题 I tried out this code and it works perfectly, until I try to change the position of the markers. For example, in the geojson array, I changed the first variable's properties and when i click it on the list, it only shows the marker (no map). Could anyone see what the issue might be?? Here is the code: http://plnkr.co/edit/ohumVwCE0CqcZOIkzPTa?p=preview var geojson = [{ "type": "FeatureCollection", "features": [{ "type": "Feature", "geometry": { "type": "Point", "coordinates": [ 34

问题 I have a map that is loading markers from a local geoJSON file. This works fine in all browsers I have tested (FF, Chrome, Safari, Opera, IE10, IE11) but not in IE9. I added a marker to the map without geoJSON (the yellow bus marker) which does show up fine in IE9. Here is the relevant code: // set up mapbox var map = new L.mapbox.map('map', '########', { tileLayer: { detectRetina: true, minZoom: 2 }, zoomControl: false }); // marker without geoJSON L.marker([-37.9, -77], { icon: L.mapbox

问题 I am working on a project that uses openlayers (version2.14)to display a Bing layer(GeoJSON format), I have no problem reading the GeoJSON and display features, but I want to select a feature programmatically, for example, there is a table displaying all the features attributes(GeoJSON format.sample: {"type": "FeatureCollection", "features": [ {"type":"Feature","properties":{},"geometry":{"type":"Point","coordinates":[-7923751.4232522,5233536.7371399]},"crs":{"type":"name","properties":{"name

问题 I am trying to convert a kml to geojson with geotools 20.5 and i am getting ArrayIndexOutOfBoundsException.
