| The organization also disseminated information on new techniques and equipment in the fields of surveying, photogrammetry, and cartography. |
| The first session of a training course in documentation using photogrammetry took place in Riga in June 2004 and concentrated on archaeological sites and historic buildings. |
| Although aerial photogrammetry was used primarily for military purposes until the end of World War II, thereafter peacetime uses expanded enormously. |
| At that time, a bunch of European and North American groups were just obtaining the first practical results of GPS positioning for airborne photogrammetry and remote sensing. |
| Such areas of survey work also rely more on modern techniques, such as satellite imagery, digital photogrammetry, and global positioning systems. |
| He and his colleagues borrowed ideas from photogrammetry, a technique used by topographers and aerial surveyors to create three-dimensional views from two-dimensional images. |
