I've got geodjango running using openlayers and OpenStreetMaps with the admin app. Now I want to write some views to display the data. Basically, I just want to add a list of points (seen in the admin) to the map. Geodjango appears to use a special openlayers.js file to do it's magic in the admin. Is there a good way to interface with...
I want to create some heat-map style tiles to overlay over our base maps using Open Layers. Basically, I want to divide some some bounding box into a grid, and display each square of the grid using a different color based on how many points of a sample fall within that grid square. The technologies involved are C#, OpenLayers, SQL Serv...
I'm using an OpenLayers-map and I want to use in it different mapservers, that use different coordinate systems. Can OpenLayers integrate it in the same map and automatically converts coordinate-systems? ...
I've seem to have hit a bug or i have overlooked something. I written some code that enumerates through all the vector features on a OpenLayers Vector layer - to check if the mouse is inside a vector feature - if so then it displays some info based on the feature. I had to write my own methods to do this because the existing OpenLayers...
I am using OpenLayers to create a box of interest with my program. I am using this code: var control = new OpenLayers.Control(); OpenLayers.Util.extend(control, { draw: function () { this.box = new OpenLayers.Handler.Box( control, {"done": this.notice}, {keyMask: OpenLayers.Handler.MOD_SHIFT}); ...
I am using an image to display my map with OpenLayers. My JS code looks like this: map = new OpenLayers.Map('map'); var options = {numZoomLevels: 7, isBaseLayer: true, }; var globe = new OpenLayers.Layer.Image( 'Globe ESA', 'http://upload.wikimedia.org/wikipedia/commons/0/07/World_map_blank_blac...
In open layers library, below is the method used to convert a screen co ordinate to latitude and longitude. I am not able to figure out the logic this method encapsulates? getLatLonFromPoint: function (point) { var center = this.getCenter(); //map center lat/lon var res = this.getResolution(); //pre defined by the u...
Due to browser restrictions I need to use a proxy to make an openlayers map work. The OpenLayers.ProxyHost javascript object handles the generation of a URL like: http://webhost:8080/app/proxy/?url=http://WFS_server/options/... Some of the requests will be GET's and others will be POST's. I've written a Servlet Filter that will recie...

I've got it so you can click on the map to add a marker and I want to then be able to click on the markers and drag it around the map. Is there a simple way to do this using either the OpenSpace or ...

I am getting this error when the map loads. The error is in the original, unmodified OpenLayers.js file on this line: return!!(document.namespaces); I have tried rewriting it to: return (typeof(document.namespaces) != 'undefined'); and it worked but then I get same "unspecified" errors on further referrals to document.namespaces: ...
I am trying to make an interactive map of a really big warehouse. I have scanned blueprints and am using OpenLayers with a TMS data source (generated using GDAL2Tiles) to display the map. Everything looks fantastic, but I'm at a total loss as to how to create a vector layer on top of it! Ideally, I'd have ~100 or so vectors on top of m...
Actually I need only the full functionality of the map but with no tiles and no requests to the server for them. Can I somehow skip them on the initial load? Is there any default parameter I can set? If not I'll make the patch myself but I'm not sure it's not done yet. ...
