Maps
A version of this map using a Virtual Earth base map is also available. Virtual Earth gives better coverage of wider Costa Rica. Originally it had limited coverage of the Leaves and Lizards property, but as of 2009, the Virtual Earth implementation includes both satellite and aerial imagery of the property.

All of the blue map icons have been supplied by Sue Pichotta of Icons-icons.com. All of these icons are © Copyright 2008 Icons-Icons.com.
Country and administrative boundary data (Outline Map layer) are shapefiles provided by the US Centers for Disease Control and made available for their Epi Info™ system.
The ASTER Satellite Image layer is a near infra-red daytime image taken by the ASTER imaging instrument flying on the NASA EOS Terra satellite. This is taken from the ASTA Volcano Archive (AVA) for Arenal. These images are available via Smithsonian's Global Volcanism pages for Arenal. This particular image was acquired on 29th August 2005, and has a Granule ID of SC:AST_L1A.003:2030725270.
The Synthetic Stream data plots rivers/creeks/streams that have been derived from DEM (digital elevation model) data. Ie. these are theoretical river positions based on height data. This works well for hilly areas, but is poor for flat and low gradient areas. The data was calculated and is available from the Inter-American Biodiversity Information Network (IABIN).
The remaining layers are KML files, created using student field data. The boundary of the main Leaves and Lizards property is taken from Costa Rica Land Registry data.
