The map has had a major overhaul which includes a lot of new functionality. The reasons for the overhaul were: a lot of the files were bloated, which caused slow download speeds; the interface was a little sloppy; there was limited area for extensions in the old system.
So, what's new?
- Completely new interface, written from scratch
- An accordian has been added on the left for ease of navigation
- Mouseover information panels
- Tile overlays instead of raw data processing
- Use of the Gaia framework for Ajax capability
- Printable details
- User-defined KML layers
- User comments area
- Photo layer from Panoramio
- Now defaults to the Terrain layer
- Data exports from the map
- Right click menu on the map
- Automated Amazon reading lists
What's in the pipeline?
- Multiple external overlays using Tile
- Street Views
- Google Earth API overlay
- User contributions via the map
Now that the map has a solid base I will be adding more tools and data over the coming weeks and months.
Hope you like the new look
