The downside is that the user has to deal with a huge amount of data, longer processing time, higher required hardware resources.
80% or even 90% forward overlap used for multiray photogrammetry). Since film and it’s processing costs are eliminated in a modern digital workflow, it looks alluring to specify higher overlaps ( e.g. The overlap (forward and side overlap ) has to be specified as well.
Video Bandwidth - (Measured in Bit Per Second) - Video Bandwidth filters noise and is used as time-domain low-pass filtering for averaging. of individual picture elements or dots that can be distinguished in a horizontal scanning line. It is recommended to specify a target GSD and a minimum GSD to allow some flexibility because of terrain elevation variation. Horizontal Resolution - Horizontal Resolution is determined by 4.2 MHz bandwidth and it can be defined as no. 5 cm) more flight lines will be required and the amount of data per area will increase. And there we have it In the next lesson, well look at web resolution, the popular belief that you need to lower the resolution of an image before uploading it. If the GSD is specified too high (high GSD means small pixel size on the ground, e.g. The selection of GSD has a major impact on flying cost and data processing cost.
