Have a look at leaflet maps - gps plugin (http://labs.easyblog.it/maps/leaflet-gps/) It automatically updates the gps location received from the device (html5 geolocation). I suppose you can attach a javascript to that updating event, to look up any POI's within a certain buffer around that gps point. These POI's can then be fed back into the leafletmap ...

I have been using OpenGeo Suite to publish maps online. It is a geospatial platform for managing data and building maps and applications across web browsers, desktops, and mobile devices.

you can find the current storage folder of the Mapillary Android app under Settings-> Developer in the app. If you go there with a file explorer, you should be able to see the originals before they are uploaded. Otherwise, clicking on an image in the approval view will open an image in the phones default picture viewer, from where you can save and share a ...

"Low cost" and "minimum development effort" are relative terms. I recently converted a Silverlight application to use the ESRI JavaScript API. I developed the app in-house so it didn't cost anything other than my salary. However, if you take this approach you will have to take into account your current knowledge of Dojo and AMD as this could impact how much ...

Check out Crowd Map from Ushahidi. It's an open source crowd sourcing map application. It definitely does points, not sure about lines and polygons. They also have a hosted version.

Use the plugin QGIS2leaf for QGIS. The plugin exports a portable leaflet map. This is basically a html-file. Your data will be in a separate data-folder, and the necessary libraries, css, etc also saved alongside. You can place the main file (index.html) and the associated files on a file share or on a intranet. The latter depends a bit on how the hosting ...

OL3 use the HTML5 Full Screen api to open the map in full screen. This api is not supported by IE 9, as you can see here. As far as I know there is no workaround.

I believe this occurs because the ESRI JavaScript API actually adds separate graphics layers for different feature types within the KML file. These layers are added after the KML file is loaded and so loaded on top of any previous maps. Perhaps you could explicitlyreorder the KML layer(s) from within an invisible widget once all the layers have been loaded. ...

You can do this by using CartoDB in combination with the Leaflet Draw plugin. You can check all the information in this blogpost. Basically, with the plugin people will be able to draw geometries on top of your map. You'll need to save these geometries in your database, and you can do this, as the example shows, by adding a security definer to your table so ...

I guess you are using GeoExt as you are talking about a "LayerTree", right? If yes, just use a OverLay-Layer-Container: http://geoext.org/lib/GeoExt/widgets/tree/OverlayLayerContainer.html var layerList = [ { nodeType: "gx_overlaylayercontainer", text: "Overlay Layers", expanded: true }]; var tree = new Ext.tree.TreePanel({ title: "Layer", loader: new ...

Leaflet is certainly a good option, out of the box leaflet does not support kml but if you add a plugin like omnivore you should be able to get things work reasonably simply. Perhaps have a shot and post your code to jsfiddle if you get stuck then someone can provide more assistance. Regards, Rowan

Currently, I don't believe ArcGIS desktop or online has an input for HEX codes. However, you can always use websites like http://www.colorschemer.com/online.html to convert a HEX code you already know or a RGB combination you have on ArcGIS to find the HEX code.
