GeoTIFF is a file format for geographical raster data. It is an image file format containing additional Geo metadata, such as the CRS (Coordinate Reference System) and the spatial extent. The metadata also include the resolution, pixel size and an optional NO_DATA value.
GeoTIFF in the Tygron Platform
A GeoTIFF in the Tygron Platform can be used to/for:
- Exporting Overlays
- Creating a GeoTIFF Grid Overlay
- Changing the Elevation model of the current situation of your project.
- Changing the elevation when applying a measure in the future situation of your project.
- Adding Groundwater data for use in the Water Overlay
- Adding foliage height for the Heat Overlay
How to create a GeoTIFF
Any Geo Data (vector or raster) can be transformed to a GeoTIFF file. Keep in mind that when transforming vector data to raster, only one attribute can be used for the raster data, since a raster dataset consists of pixels or cells with one value and optional a color value. Transforming Geo data can be done with for example a GIS (Geographical Information System).
Requirements
The following requirements for a GeoTIFF file apply:
- The file should have a CRS defined, for the Platform to properly translate the coordinates to the right location.
- The file should have a resolution
- The file should have a pixel size
- The file should have a spatial extent
How-to's
- How to export a Grid Overlay as GeoTIFF

- How to import a foliage height GeoTIFF
- How to use a default groundwater GeoTIFF (Water Overlay)
- How to upload and use a groundwater GeoTIFF (Water Overlay)
