big picture.

What is Photokan ?A digital photogrammetry tool

Enhances the quality of the image.Takes into account the parameters of the

cameras that take the photographsGeographically aligns the images on earth

surface, provides spatial coordinates of points on images

Products of PhotokanDigital Elevation Models (DEM)

A height map of the terrain

OrthophotosGeometrically corrected aerial imagesEquivalent of mapsCan be used to measure true distances

Products of PhotokanMosaics

A combined image of intersecting photos, or frames of a video

Application Areas of PhotokanAfter disasters

Analyzing the effects of the disaster on earth surface, and creating an emergency plan accordingly.

Military Tactical OperationsGathering information about critical terrain

topologyPolice InvestigationsArcheological Terrain Surveys etc.
