Elevation and coastal bathymetric model for Bonaire

Improved AsterDEM for Bonaire rescaled to 1-meter spatial resolution and 1m height resolution.

The ASTERDEM has been improved amongst others for making a bathymetric model and for that reason the ASTERDEM was converted to contour lines, and to improve the calculations extra height points were added for the lowlands of Bonaire, as well as extra measured sea depth points that were collected in a separate campaign to calculate a new bathymetric model that interpolated the improved DEM with the measured sea depth points.

Improved ASTER elevation model for Bonaire

Improved AsterDEM for Bonaire with a 10-meter spatial resolution and 1m height resolution.

The ASTERDEM has been improved amongst others for making a new bathymetric model and for that reason the ASTERDEM was converted to contour lines, and to improve the calculations extra height points were added for the lowlands of Bonaire, as well as extra measured sea depth points that were collected in a separate campaign to calculate a new bathymetric model that interpolated the improved DEM with the measured sea depth points.

The coastal bathymetry is not included in this dataset. Please see this dataset for a 1 meter resolution elevation model including the coastal bathymetry.

Production of Digital Terrain Models for the Dutch Caribbean

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.
