Take a look at our API directory and you will quickly note that the Google Maps API continues to reign as the most popular API used for mashups. As the API continues to gain momentum, several new utilities have emerged to improve the user experience (or UX as it has come to be known).
First up is GeoStart, a startup from the Netherlands, which has open-sourced two helper utilities to the Google Maps open-source utility library: ProgressBar Control and SnapToRoute. The ProgressBar Control creates a status bar that shows the progress of markers being added and removed from the map. SnapToRoute lets you snap a marker to the closest point on a polyline, ensuring that the marker is always somewhere on the line. [via Google Geo Developers Blog]
We are excited about these new utilities, and we're looking forward to seeing the innovative ways that developers will use these in the ever-growing number of map mashups out there.
