Relating data accuracy with slope values

Post by juliet »

Hello everyone,
Please I need suggestions with regards to a write up I am working on. I am trying to assess techniques in Topographic mapping and I utilized a time of flight laser scanner, phase shift laser scanner and UAV for data collection. I have been analyzing each technique based on cross sections I acquired from their respective DEMs. Now I want to use their slope values to evaluate data accuracy but I am stuck here. Although I have superimposed Linear Trendlines on each cross section to obtain an equation of a line in the form of y=mx+c with m been the slope. Now I need to assess the accuracy of the techniques (data accuracy) with slope values.

I would appreciate any information on this. Thank you.
