What are the most important developments in photogrammetry and remote sensing?
There have been many developments over recent years. The most significant include both high- and medium-resolution digital aerial cameras and Lidar with ever-increasing capabilities, including pulse repetition frequencies of over 200kH, multiple pulses in flight and full waveform sensing. There have also been the proven demonstrations of applications of interferometric synthetic aperture radar (SAR) for digital elevation model (DEM) generation and ground subsidence. Many countries have launched commercial high-resolution satellites, including the new generation of small satellites. There have been applications of ISPRS technologies for disaster management, Web-based GIS applications have been developed, and Web 2.0 has impacted the acquisition and distribution of spatial information. Where in the world are developments taking place most rapidly? Most developments in new technologies for data acquisition are coming out of Europe and North America. That said, new technologies are also be
