Automated Georeferencing of Historic Aerial Photography
Historic aerial photos are typically very popular, sought-after collections in library archives. Their ability to be used in GIS is limited, however, by the laborious and painstaking georeferencing process. A method is presented for automating the georeferencing of historic aerial photography. In this method, the Harris Corner Detector is used to detect corner points in already-georeferenced an...

متن کاملColour Aerial Photography for Riverbed Classification
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 project that sought to assess this potential and consider the impact of photo-scale on the accuracy of classifications obtained. Colour multi-scale digital imagery was acquired of a test area (120 x...
متن کامل3-d Terrain Reconstruction with Aerial Photography
This paper presents the 3-D terrain reconstruction with aerial photography. The results of 3-D reconstruction using intensity-based matching and hybrid intensity-based and epipolar geometry approach matching are shown and compared. The intensity-based image matching uses maximum normalized cross correlation to find the displacement vector between two images. This method can overcome the effect ...
متن کاملWhale Detection & Identification from Aerial Photography
The North Atlantic Right Whale is a critically endangered species of baleen whale, with an estimated fewer than 500 individuals living in our oceans [1, 2]. In the interests of science and conservation, it is necessary to track and monitor these animals. Currently, only a few experienced researchers are able to identify and tag individual whales through the use of custom software and this proce...
