The algorithm, because of its ability to extract and fully exploit the elevation information derived from a digital model, it can prove particularly useful in forested areas with steep-sloped terrain.
To generate prismatic shaped structures with vertical walls and flat roofs, building shape is retrieved from the cadastre database while elevation information is extracted from the DSM.
The elevation information was extracted from the SRTM database (a digital terrain model obtained from the Space Shuttle mission).
The upper ring of antenna elements in the ODA was not operative on one link end, so elevation information was not extracted from the measurements.
However, we generated our phenological information from herbarium specimens: few had elevation information, so effects of elevation on flowering phenology cannot be examined particularly in light of the coarse spatial resolution of our weather data.
The important observation from the data in Figure 3 is that using solar elevation information to influence the interpretation of the outputs from colour constancy algorithms might improve the results obtained.
Ground surface elevation at well location was obtained from SRTM 30 m DEM, since elevation information in the toposheet was limited due to the relative flatness of the terrain.
