A SWOT analysis of the sources of 3D information, from laser scanning and imagery, is conducted as a comparative analysis. This paper presents a review of the present integration methods. ![]() ![]() In addition, the challenges represented by four dimensional (4D) modeling require additional adjustments and modifications, due to restoration procedures, excavation, weather conditions or natural phenomena factors. The integration of both output data sets from the two techniques, photogrammetry and laser scanning, is a prerequisite to take advantage of the complementary characteristics. Both technologies provide dense 3D point clouds, neither represents a clearly superior result in terms of quality. In contrast, photogrammetry Dense Image Matching (DIM) generates dense colored point clouds and concentrates on representative structures of the object.

Point clouds are currently the most popular laser scanning approach. Also, new methodologies in cartographic production have become possible. Developments in photogrammetry systems together with terrestrial laser scanning workflows are creating increasingly comprehensive and accurate 3D colored point cloud data.
