Street View now in Full-Screen

Thank the Google Maps team!!!

Now, we get to see impressive street view sights in full-screen. I believe its even more eye-catching and stunning navigating around in full-screen if you got a sizeable lcd monitor.

User taken photos of the location are also available for viewing in full-screen.

Launch street view in full-screen by clicking fullscreen at the top right corner of the map viewer.

Check out the Roman Colosseum in full-screen

Read XML files using the Google Maps API

Looking to build a Google Maps mashup by reading geo-enabled information from an XML file?

Here’s a post from GeoChalkboard explaining by way of examining a simple application that displays geologic points of interest from around the state of Texas available in an XML file format.

The tutorial highlights the usage of two methods (GXmlHttp and GDownloadUrl) provided by the Google Maps API to read XML files.

Lat long coordinates and information associated with each point of interest are read from the file and markers are generated with location information being displayed via an information window.

If you are just beginning to create Google Map mashups and looking for some simple examples on using XML files and the maps API, check out my previous posts.

ESRI Videos on YouTube and Viddler

Among the GIS blog world, this is the fourth posting today on ESRI’s official YouTube channel.

ESRI operates a channel on YouTube under then name esritv which is a useful resource with videos on product demos, conference presentations, howto’s, process work flows and other interesting stuff.

It so happens that many of the videos uploaded on YouTube can also be found on Viddler, probably uploaded by the same professionals. Just in case you happen to have problems accessing YouTube, don’t’ panic and remember that there’s Viddler.
