• Extract edge features or line-shaped objects: From photogrammetry, such as single images, stereo images or multiple images
• Planar feature extraction: Often relies on texture recognition and therefore recommended to acquire from laser point clouds

• Contours are lines along which the surface orientation sharply
  changes. They are important features for structuring point clouds.
• With the help of contours, one can convert the point clouds into high-quality surface or solid models, which are widely used in graphics and mapping applications.

• Orthophoto is a geometrically corrected aerial photograph or satellite imagery that is an accurate representation of the Earth’s surface.
• An Orthophoto is adjusted for topographic relief, camera tilt and distortions caused by the lens.

Our Orthophoto Production Services include:

• Base layer maps for GIS
• Geo-referencing
• Construction of Orthophoto Mosaics
• Digitization and transformation between digital formats
• Orthophoto color balancing, seam-line editing and tile cutting

• We produce Trimble Locus 3D base maps that are compatible with LOD2 level roof vectors.
• The Open Point Cloud from the National Land Survey can be used, but the best result is obtained from a more dense point cloud
• We can make a cross-comparison between building points and point cloud-rated buildings if the construction points are available.
• In addition, missing stone foot vectors can be generated by standard indentation roof vectors.
