| 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. |
| 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. |
| Remote sensing data using satellite images or photogrammetry to analyse land use cover, classification of vegetation and forest inventories. |
| These subjects include computer, cartography, meteorology, survey and photogrammetry, remote sensing and geographic information system and nutrition. |
| 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. |
| Training in photogrammetry is offered and has promoted the establishment of mapping facilities and programs in many of the collaborating countries. |
