Layer from cnigshd, 6 ans ago

This layer is a topographical raster map showing hillshade for Haiti. It is based on a Digital Elevation Model (DEM). This kind of map is commonly used as a background to other layers to improve the realism of the visualization. Created in June 2010 by the NATHAT mission. It needs information regarding the DEM features.

This raster layer shows the relative relief [m/Km2] of Haiti, with pixels of 30 meters. It was created by NATHAT project in May, 2010, using a digital elevation model (DEM). The relative relieve shows the range (maximum elevation minus minimum elevation) in an analysis area, generally 1 Km2. [It needs improvement by improving the scale, and improving the DEM]

This raster layer shows the relative relief factor for Haiti, with pixels at 30 meters. Relative relief factor is the slope angle difference between the hill top and hill bottom, expressed as a factor (percentage, in this case, apparently classified in categories with a range from 1 to 5). It was created by NATHAT project in May, 2010. This factor was created from Digital Elevation Model. [It can be improved through by improving the data elevation model. The current layer needs information about the classification]
