Biomass Estimation Using Digital Photogrammetric Cameras
Estimating and modelling biomass can be helpful for biomass management. It is also interesting to calculate the amount of biomass in a certain area for carbon implications, as indicated by the Kyoto protocol. In the past remote sensing techniques have been able to estimate biomass by using reflectance in the both the red and the near infrared wavelengths. Nowadays the sensors in the digital pho...
متن کاملDevelopment of Digital Aerial Cameras
Digital aerial cameras have replaced analogue aerial cameras in several countries. The development for operational aerial photogrammetry started with the line scan camera ADS40, followed by Z/I Imaging DMC and Vexcel Imaging UltraCam. Recently the line scan camera Jena Optronik JAS-150 was introduced. The capacity of the UltraCam was enlarged by replacing the used CCDs with 9μm pixels over 7.2μ...
متن کاملGeometry and Information Contents of Large Size Digital Frame Cameras
Large size digital aerial frame cameras like Intergraph DMC and Vexcel UltraCam are becoming standard for photogrammetric application. It is difficult to compare the information contents of such cameras with this of analogue photographic cameras. Also the rules for project planning have to be checked if the old relation between photo scale and map scale is still valid. The photo scale has no lo...
متن کاملRecent Developments of Digital Cameras and Space Imagery
Digital aerial cameras have replaced analog film cameras. An information contents corresponding to aerial photos up to 2010 was only possible with digital system cameras as Vexcel Ultracam and Z/I Imaging DMC or line scanning cameras as Leica Geosystems ADS80 or Jena Optronic JAS-150. Now with very large size CCDs the panchromatic band of the DMC II has between 140 and 256 Mega pixels from one ...
متن کاملThe Ultracam Large Format Aerial Digital Camera System
The race is on to introduce an aerial digital camera system to outperform the current aerial film cameras in quality, accuracy and economics. We introduce the UltraCam-D large format digital aerial camera. It achieves superiority over conventional aerial film imaging. The system produces aerial "photography" as if a film camera had taken film images that then were scanned. As a result, images t...
