You need to know the coordinates of at least one point in lat/lon degrees. If you don't have any surveying points, you might take coordinates from a GPS unit if the point is visible. Using QGIS, you could create the other points of the polygon with the Azimuth and Distance Plugin. Take care to convert the degree-minute bearings into decimal degrees. EDIT ...

Trying to find a solution, I've changed OpenLayers.js file, provided by plugin authors (which had 'Release 2.11' version in his body and was placed at ~/.qgis2/python/plugins/openlayers_plugin/weblayers/html folder in my system) to last 2.13.1 version from official OpenLayers site (pay attention, 2.+ version!). Just download the archive, extract to ...

Your Gauss-Krueger projection uses +datum=potsdam. Up to 2012, this was hard coded in proj4 to a very unprecise value using a 3-parameter-transformation. You find more exact values for 7-parameter transformations in this topic: http://forum.openstreetmap.org/viewtopic.php?id=12723 There is an even better ntv2-grid transformation available here (take the ...

Good question. You can achieve this in an ArcGIS Web Map by providing a custom value in the popup window. I added a sample New Zealand schools layer by searching for "school" within ArcGIS Online. This sample dataset contains a field called ADDRESS which lists the school's address. Next choose > Configure Popup: Choose a Custom Attribute Display, and ...

It will never work. You are using code for the deprecated Google Maps API v2. Trying what's happened with the sample, I get a message like below Control is no longer supported in the Google Maps Javascript API v2. Please visit developers.google.com/maps/documentation/javascript/v2/v2tov3 to migrate your application to v3. I didn't dive into the ...

here.com's API can, supposedly, give you up to 100 addresses within a circle. This is how I create the URL for the API call function makeURL ( point, radius) { return 'http://reverse.geocoder.cit.api.here.com/6.2/reversegeocode.json' + '?app_id='+config.Here.App_Id + '&app_code='+config.Here.App_Code + ...
