Production of Digital Terrain Models for the Dutch CaribbeanSubmitted by Peter Verweij on Thu, 12/11/2014 - 15:24
Bonaire, St Eustatius and Saba, islands in the Caribbean, became Dutch municipalities in October 2010. These islands are considered hotspots of biodiversity. This brings along specific responsibilities, including a thorough conservation plan. Each plan and monitoring of it demands good basic knowledge and data. It is of great importance for many studies to have proper altitude maps, in addition to good topographical maps. Detailed elevation maps (Digital Terrain Models) are important not only for preprocessing of high resolution satellite imagery , but also for e.g. geomorphological studies, soil surveys, hydrological modelling, species niche modelling, that all need altitude as an important input data layer. At present there are no detailed digital terrain models for these islands, while these are especially important for Saba and St Eustatius that have a very varied and complex topography.
