Digital Elevation Model for Peru:
HIGH RESOLUTION TOPO ONLINE
Our team of Geoscientist and spatial analysis experts have put together the entire Peruvian territory with a high resolution topographic dataset. The derived products were generated from a 30 m cell size DEM that present a vertical accuracy of 4 m. These products were extracted using satellite images at a resolution of 15 m. This topographic information is equivalent to a 1:20 000 topographic scale.
TILES & PROJECTION
The country is divided into 106 tiles projected in PSAD56 WGS84 Datum. Each tile overlap it's neighbour with 1 km permitting to create a perfect mosaic for your study area. All 3 products are available for the entire country.
Hillshaded relief were generated by illuminating the DEM with an azimuth angle of 45 degres and an elevation angle of 35 degres. These values provide the perfect hillshaded effects. This product is offered in grey levels. The grey level is useful when the user needs to overlay a satellite image with transparencies. This product is offered in .tif 8 bits.
CONTOURS (25 m)
Contours are generated applying new algorithms over the original DEM. Since the original data present a resolution of 15 m, we have extracted the contours for each 25 m intervals. This is comparable to a 1 : 20 000 Scale topographic map. This vector layer is formatted in .SHP for ArcGIS.
