A hierarchical-scale of landscape configuration and habitat characteristics was measured for eight seagrass beds using aerial photographic analysis (e.g. core area, contiguity and other landscape metrics), digital echo-sounder data (e.g. depth, canopy height) and diver surveys (e.g. epiphyte load).
The state bureau of cultural relics is conducting a study of the wall using aerial remote sensing equipment, simple tape measures, GPS systems and photography, to find out its precise length.
First, we mapped individual lava flows using aerial and satellite (ASTER) imagery, and validated our remote observations during field campaigns, when we also measured lava flow thickness.
This information can be corroborated using aerial or satellite photography.
It was lost for many years until the French rediscovered it in 1917 using aerial photographs.
We used monthly averages for 13 sites within community spaces, geocoded by hand using aerial photography.
The original map was produced using aerial photographs and ground truthing.
Census block group data from the 2000 U.S. Census (U.S. Census Bureau 2002) were used to measure neighborhood demographic and socioeconomic characteristics (including percent poverty, defined as the percentage of residents with incomes below the federal poverty line), with block group–level data aggregated to neighborhood buffers using aerial weighting interpolation.
Furthermore, We also established toxicant bait stations, using strychnine, to augment aerial shooting and to target wolves that could not be found or removed using aerial-shooting.
We used aerial and satellite imagery, coupled with field observations, to measure and characterize the changes in the landslide dams and lakes over time.
