Terrain Model Download, grid 1+ is a terrain model containing points with coordinates and height values in a regular grid with 1 meter spacing with high altitude accuracy. The product name in Swedish is Markhöjdmodell Nedladdning, grid 1+.
About this product
Terrain Model, grid 1+ is a grid in raster format with one meter resolution created through interpolation from the National Elevation model.
Examples of applications
- generation of height contours and for development of digital terrain models that depict the landscape in three dimensions
- calculations and analyses for creation of altitude- and terrain shading in maps
- gravity determinations
- geometric correction of satellite images
- climate adaptation measures, such as flood mapping
- planning and building permits near water
- planning for climate and environmental change
- optimal location of wind turbines, transmitter masts for mobile telephony
- base material for orienteering maps
Geographical selection: Index tiles (2,5 x 2,5 and 5 x 5 km), polygon, cut-out with min/max-coordinates, county, municipality, Sweden.
Delivery formats: LZW-compressed GeoTIFF
Coordinate systems: SWEREF 99 TM (EPSG:3006), SWEREF 99 local zones (EPSG:3007-3018).
