Synopsis of Topic
We will recap the information covered on Day 2 with an emphasis on realizing that there are many ways to undertake change detection analyses. At the heart of change detection is appropriate, independent models of errors for each DEM being compared in the analyses. We emphasized today a variety of choices you have in building spatially uniform or spatially variable error models. We are not advocating any single technique, but instead trying to equip you to make an informed and appropriate decision based on your circumstances about how to proceed through the process of geomorphic change detection. Ultimately, Day 2 is boring, due diligence you need to undertake in order to explore interesting applications and make reasonable interpretations of your repeat topographic surveys with some confidence.
Why we’re Covering it
To make sure that workshop participants are confident in understanding the basics of change detection and surveying principles, before using these techniques in any sort of interpretative fashion (Day 2).
