With the advent of newer earth imaging satellites with daily overpass and capture possibilities, it is now even easier to monitor land use change. For example, we can examine the history of development of two Economic Land Concessions (ELCs) inside the Beng Per Wildlife Sanctuary. The concessions were granted in... read more →
Well I've finally manged to get my hands on some SPOT DEM data for Cambodia for a project in the Southern Cardamoms. Quite an improvement over the SRTM (90m) data. The SPOT DEM has a resolution of 30m at the equator. From Astrium: A SPOT DEM is a digital elevation... read more →
The declaration of the accuracy by Garmin GPS receivers often leads to confusion. What does it mean if the receiver states an accuracy of 4 m? This readout refers to the so-called 50 % CEP (Circular Error Probable). This means that 50 % of all measurements are within a radius of 4 m. On the... read more →
We often get asked about this question, so here are the full instructions on how this can be done: Topographic maps in Cambodia use one of two datums; Indian 1954 and Indian 1960. By default, your Garmin GPS unit is set up to WGS84 datum, which is about 500m different... read more →
