I did a simple comparison a year ago showing eleven different geocoding services, free ones as well as pay services, and the results are in a google spreadsheet. I work at SmartyStreets, so you'll see that listed in the first column but not in first place. I tried to make the comparison unbiased so the results are actually useful. I have now opened the ...

The Texas A&M Geoservices site has a comparison of the main features of several geocoding systems - http://geoservices.tamu.edu/Services/Geocode/About/GeocoderList.aspx. We try to keep it as up to date as possible.

You should be able to adopt the following Python code to the language of your choice. Grab the coordinates of your map center and determine if it falls within the bounding box of the contiguous 48 states. #More accurate values can be found @ #en.wikipedia.org/wiki/Extreme_points_of_the_United_States top = 49 #northern-most latitude left = -124 ...

If you need the map only to apply a vector layer on it, why didn't you use the OpenLayers Plugin? Now, about the MapQuest: remember that map consists of a lot of 256 x 256 px tiles. As stated here they currently offer two tilesets: the MapQuest-OpenStreetMap Tiles and the MapQuest Open Aerial Tiles. You can freely use only the MapQuest Open Tiles (under ...

The controls on the map appear to be OpenLayers. Here's how you can find out yourself what kind of data it's using in the client in Chrome or Firefox: In Chrome, go to Menu > Tools > Developer Tools and switch to the Network tab. In Firefox, go to Menu > Developer > Network Refresh the page, pan around the map a few times, see what resources load.

I'm afraid it's impossible. Mapquest provide this service for free and quite reasonably do not wish to allocate resources to unreasonably large requests, as they would take up disproportionate server time and degrade the server for other users. As an aside if you are doing this for either large amounts of data or frequently, you should consider using a ...

Tools: TileMill can export a map to MBTiles out of the box, there is an item in "Export" drop-down menu. And yes, you can add GeoTIFF as a layer. Data: If you want complete freedom, download a PBF extract (geofabrik's are good), install PostgreSQL and import data there (see this tutorial). This way you can use any data that OpenStreetMap provides. For ...

You need to geocode the addresses, I would use mapquest, then you have a list of points, so you could calculate the shortest distance between two points(house and POI): function getDistanceFromLatLonInKm(lat1,lon1,lat2,lon2) { var R = 6371; // Radius of the earth in km var dLat = deg2rad(lat2-lat1); // deg2rad below var dLon = deg2rad(lon2-lon1); ...

The current version of openlayers plugin has solved the blur effect in a better way than the blogpost did. Changing CRS to EPSG:3857 might also improve the picture.

Lot of posts says that OSM currently doesn’t have much "house numbers" loaded. Indeed, here in Buenos Aires, a very few streets have house numbers on it. In OpenStreeMaps.org, if I enter this: "750 lavalle, ciudad autonoma de buenos aires, argentina" ... and click in the first suggested option, the viewer shows the correct street, but the place mark is on ...
