Abstract – The first step in any and all digital modeling endeavors is obtaining field
data. Measurement techniques vary in complexity and accuracy from the most basic
tools such as a measured piece of rope, to the electronic total station, to aerial
photogrammetry and LIDAR and satelite imagery. One of the most accurate and
efficient methods is aerial photogrammetry because it can cover extended areas quicker
than land based measurement systems and has much better accuracy than satellite
measurements. Also it is becoming more affordable and easy to operate, to the point that
it requires very little operating experience. As such, measurement trials using UAV
photogrammetry have been carried out in preparation for a study that requires digital
modeling of the terrain for rainfall parameter analysis and comparison.
