Inverse Distance Weighting



This is a raster map (created by the inverse distance weighting technique) using NASA SRTM data as an elevation source. I've used red panda (Ailurus fulgens) presence/absence data collected by my colleague Tanushree; the scale is a gradient from white (high probability of presence) to black (low probability of presence). The underlying layer is a Landsat false-colour image.

There's no scale on this map because the skewed perspective means that the scale increases towards the horizon, and decreases towards the observer.

This is a section of the Brahmaputra that flows through Assam. It's a beautiful river.


The Tso Kar Basin

The Tso Kar basin in southern Ladakh is one of the most beautiful places on Earth. It contains freshwater, saltwater, desert, alpine and wetland ecosystems in close juxtaposition at a height of 4600m above mean sea level. These maps show water surface and wetlands in 2000 and 2006. Play spot the difference?

Salutations to Ganesha

As the first post, this one has the dubious honour of explaining what this blog is about. Come on then, step up to the mike.

Maps.



This is a portion of the Pangchen valley, in Western Arunachal Pradesh. It's sourced from bands 4 and 5 of the Landsat 5 Thematic Mapper sensor.
