April 2009 Archives

The panoramic images are now displayed using a new comparison viewer. This allows you to view panoramic photographs taken at the same location but from different years. A slider fades the view from one image to the other image.

Note: As the 2009 images have not yet been taken these appear black. When using the viewer, you will need to move the slider from 2009 to 2008. This will fix itself as we create the new 2009 images next month.

Also, last week I added a new aerial photograph to the Virtual Earth version of the maps. As with the ASTER image on the same map, this was converted into map form using Microsoft's MapCruncher program. It was tied to the real world using GPS coordinates taken during the 2008 field season. The aerial photograph is much higher resolution than the ASTER image. It was taken after the cabins were built but before the first plantations were planted.

Yesterday I published an article at GeoWebGuru about how the ASTER satellite image was added to Virtual Earth using Microsoft MapCruncher and Amazon S3 & Cloudfront:

Add your own Satellite Images to Virtual Earth with MapCruncher and Amazon S3

A new version of the Virtual Earth map is now online:

(Click on the map image to reach the main map application)

This version is a completely native Virtual Earth application and does not use OpenLayers or MapServer WMS. The map is now full-window sized, without the header and side bars. You can zoom in much more than the original version, and it also now supports the Virtual Earth 3D control!  Yes you can fly around a reasonably high resolution 3d Volcan Arenal, or soar along the Leaves & Lizards ridge.

The above map will probably become the main map in the next few weeks.

The satellite image was tiled using Microsoft's MapCruncher, and the tiles are stored on Amazon S3 servers and distributed using CloudFront. I shall be publishing a how-to article at GeoWebGuru about this on Monday.
