bing-maps

问题 I am trying to show bing maps on my React Application using props. The Maps are properly displayed on load but when the props change it will not reload the map component. I know the issue is componentDidMount() will be called only once when the component loads but I am not sure how to resolve it. interface IState { addresses: Array<PropertyDetails>; } interface PropertyDetails { fullAddress: string; propertyNumber: number } export class Map extends React.Component<{ data }, IState> {

问题 I wish to add the Bing Maps Autosuggest API to two fields in my form. When I execute the code, the autosuggest API works just for one field and not the other. Below is what I got so far : <script type='text/javascript'> function loadMapScenario() { Microsoft.Maps.loadModule('Microsoft.Maps.AutoSuggest', { callback: onLoad, errorCallback: onError }); function onLoad() { var options = { maxResults: 8 }; var manager = new Microsoft.Maps.AutosuggestManager(options); manager.attachAutosuggest('

问题 I have two coordinates of a street. Either both Odd or Even. So for example 15 ABC Street and 77 ABC Street (with their reverse geocode). I'm trying to draw a path line that is near the sidewalk. I used google maps api and did not find a way to do it. The directions api draws a line in the middle of the road, and I cannot find a way to do a geometric translation to either side of the street. I don't mind using any other API as long as I can solve the problem. 来源： https://stackoverflow.com

问题 A little about the application; The application allows the user to draw and save polygons onto bing maps WPF api. The piece of code we are interested in is finding weather a point is whithin the polygon or not. The following function simply loops through the LocationCollection of the polygon on the bing map, and creates a SqlGeography object (OpenGisGeographyType.Polygon) which is an instance of a polygon. We then convert the mouse click into SqlGeography object (OpenGisGeographyType.Point)

问题 I'd like to work out the distance between two points. No map. No javascript. Just the distance. I understand Google maps prohibits this and it's against their terms of service. But Bing Maps doesn't have this restriction. I want to give the points in a general format, i.e "Cambridge" "Church Street, Newcastle" How would I go about doing it? As basic as possible. It's for a mobile device. 回答1: 1.) Sign up for a Bing Maps key at http://www.bingmapsportal.com. A key is a alphanumeric string of

问题 It's any public maps API (google, microsoft, openstreet...) that returns the height of the roof for certain points? Imagine: you request some address and the API returns the coordinates, some information and the height of the building, if available. 回答1: OpenStreetMap has a height tag and various other building related tags like building:levels from which you could estimate the height. However note that currently most buildings lack those tags as they aren't widely in use so far. Still you

问题 I'm working on a site that makes use of v7 of the Bing Maps AJAX Control. One of the things I need to do is restrict the zoom level so as to prevent users from zoom in past a certain level, or zoom out past a certain level. I found a "getZoomRange" method on the Map object, after inspecting it, it simply returns an object literal with "min" and "max" properties. So, I figured overloading it would probably do the trick: // "map" is our Bing Maps object map.getZoomRange = function () { return {

问题 I have a question very similar to this: How to know if a line intersects a plane in C#? I am searching for a method (in C#) that tells if a line is intersecting an arbitrary polygon. I think the algorithm by Chris Marasti-Georg was very helpful, but missing the most important method, i.e. line to line intersection. Does anyone know of a line intersection method to complete Chris Marasti-Georg's code or have anything similar? Is there a built-in code for this in C#? This method is for use with

问题 I have the requirement in my WP7 application to display pushpins on a bing map from multiple data sources and I am not sure of the best way to do this. So for example it would be something like this, I receive from a web service a list of people, a list of buildings, a list of POIs etc. I would need to display these individually in their own views but also display them on a map with different images for each type. I am trying to use a MVVM approach so have a class for a Person, class for a

问题 Was wondering if anyone has any experience or could help with the logic, to track a user (car) with Bing maps As the user travels a line should be drawn of their journey, but snap to roads, the way I have things set at the moment, lines will be drawn through buildings. Because whenever there is an update to the position, 2 points are calculated and a line is added to the map (At the moment am using watchPosition but in future will get position every 30 seconds) watchPos() { let options = {
