Understanding and protecting cultural heritage involves the detection and long-term documentation of archaeological remains alongside the spatio-temporal analysis of their landscape evolution. Archive...
The problem of accuracy determination of the UAV position using INS at aerial photography can be resolved in two different ways: modelling of measurement errors or in-field calibration for INS. The pa...
The assessment of anthropogenic impacts on the marine environment is challenged by the accessibility, accuracy and validity of biogeographical information. Offshore wind farm projects require large-sc...
Automatic image matching algorithms, and especially feature-based methods, profoundly changed our understanding and requirements of tie points. The number of tie points has increased by orders of magn...
Aerial photography has been acquired regularly for topographic mapping since the decade of 1930. In Portugal there are several archives of aerial photos in national mapping institutes, as well as in l...
Seasonal snow plays a vital role in the world's water resources. In some areas, seasonal snow melt provides water for agriculture, industry, hydro-electricity generation and urban water supply. Accura...
Giant reed is an invasive weed throughout the southern half of the United States, with the densest stands growing along the coastal rivers of southern California and the Rio Grande in Texas. The objec...
Texture measures are commonly used to increase the number of input bands in order to improve classification accuracy, especially for panchromatic or true colour imagery. While the use of texture mea...
A study of back-barrier salt marshes was conducted to investigate whether or not urbanization has impacted the distribution and fragmentation characteristics of the marshes. Topsail Island and Masonb...
In order to adequately model ecosystems services of the urban environment, it is necessary to accurately inventory urban vegetation abundance and spatial distribution. An object-based, methodological ...
COLOUR AERIAL PHOTOGRAPHY FOR RIVERBED CLASSIFICATION     Hydrology  Classification  Scale  Texture  Orthoimage  Land Cover  Aerial       font style='font-size:12px;'> 2015/7/30
Colour aerial photography has the potential to identify and classify the size characteristics of exposed riverbed sediments over large areas efficiently. This paper describes the findings of a pilot...
The theoretical conclusions and practical results described in this article are based on the extensive experience of geodetic, photogrammetry and aerial survey works that are being implemented by Geok...
The report reviewed the algorithm fuzzy c-means, performs image segmentation, give an estimate of the quality of his work on the criterion of Xie-Beni, contain the results of experimental studies of ...
Kite aerial photography (KAP) involves large kites for lifting cameras 50-150 m above the ground. Either soft (airfoil) or rigid (delta, rokkaku) kites may be utilized in wind ranging from 10 to 40 ...
It has been demonstrated that the height of forest canopies can be measured with a good accuracy using small footprint lidars. This is essentially accomplished by subtracting the last return altitude ...
