Orthophotos 2.5D (DTM)

Digital terrain models (DTM) in 2D raster images illustrating relief (using the Z-Value of LiDAR data).

File formats:

  • Colored: .jpg, .png, .gif, .tiff (GeoTIFF);
  • Digital: .tiff (GeoTIFF, BigTIFF).

Specifications when ordering:

  • The geographical coverage (a city, a boulevard, a neighborhood, any area specified by you ...);
  • The geographical dimension of the tiles (square tiles of 100 x 100m, 500 x 500m 1 000 x 1 000m);
  • The pixel size of the tiles (pixel size in land units, e.g. 1x1 pixel covers 10 cm x 10 cm of territory);
  • LiDAR source points of the GROUND class;
  • Selected LiDAR points per pixel: images generated from the HIGHEST point (to highlight roofs and vegetation tops), the LOWEST (to aim for the most accurate representation of the ground), the AVERAGE (average value of the points in a 10 cm x 10 cm pixel or cell) or the CENTER (value of the most central point in the cell)
  • Possible delivered files:
    • Fixed option: With fixed colorization (conventional or customer specified) in grayscale or RGB;
    • Flexible option: Values of the chosen LiDAR point (low, high, middle, or central point) in order to let the end-user choose his use (colorization, visualization, interpretation ...);
  • Flexible multiband option: Results according to different choices (low, high, medium, and central point), on different bands.

Consult the coverage map to see if your territory has already been digitized!

If your geographic area is not yet in the Jakarto catalog, and according to our geographical coverage planning, the data can be produced as a priority. For an area outside of our planning, a request for production can be made after an evaluation. In this case, you can expect a production and delivery time between 5 and 10 weeks.
