Surface Model Download, from aerial photographs

Surface Model Download, from aerial photographs consists of height points, with or without colour, created from aerial image matching. Previously, the product was called Surface Model from aerial photos. The product name in Swedish is Ythöjdmodell Nedladdning, från flygbilder.

Brief information

A Surface model is a type of elevation model that describes what can be seen from the air. The top of vegetation, buildings and other artefacts above ground are included (unlike a terrain model where such over ground features are omitted). For open spaces where there is no vegetation, buildings or other artefacts the surface model shows the ground surface. The points that make up the surface model are not a 3D swarm of points, it is a layer of elevation-based points (2.5D model).

The surface model contains elevation points created from aerial image matching. The product is available in two variants: Surface model from aerial colour photographs and Surface model from aerial photographs, which is delivered without colour scheme. Metadata for the product is included in the delivery.

Examples of the use of Surface Model from aerial photographs

The surface model has several uses, for example it can be used to elevate 2D data to 3D, calculate forest growth or carry out change detection between different years of photography or simulate how gas emissions are spread.

Maintenance and update frequency

The production follows The national image provision programme. New data is added as new aerial photographs become available over approximately 1/3 of Sweden each year.

The areas that can be ordered from each year of aerial photography are reported under the tab Plans and outcomes.

Plans and outcomes

The production follows the The national image provision programme and new data is added annually as new aerial photographs become available.

Production status

Production status is updated every day and reports which areas are ready to order from each year of aerial photography and what resolution each area has.

Missing areas

When matching images over areas that are largely covered by water, i.e. some lakes and in the archipelago, some areas may be missing. This means that some islands, skerries and headlands are not included in the surface model. Where the missing surfaces are is shown in the shapefiles below and in the pdf-file on production status.

The Shape files show:

  • Missing areas - index tiles (shows tiles with missing areas).
  • Missing surfaces - polygons (shows the exact extent of missing data).
