Geological Remote Sensing in eCognition
Firstly I am very new to eCognition cloud-based software application with limited remote sensing experience.
Question - Which Expert Rule Set(s) in eCognition might prove to be useful to meet my objective defined below?
Objective - to map geomorphological and lithological characteristics in a remote dry desert landscape in eCognition. I have the ability to ground-truth some of the classified areas to assess accuracy although not all.
Data Considerations
- Image Data - Hyperspectral Imagery if available that includes VNIR-SWIR datasets WorldView 3 or other if available
- Surface elevation data - High Resolution lidar nDSM
- Vector data-existing vector shapefiles I have to assist in verifying the analysis
Workflow in eCognition Rule Sets being Considered
- Rule-based eCognition experimentation to detect lithological/geomorphological features in the AOI (error detection early on)
- Use-Update Vector Rule Set>Reset>Load Data
- Use Support Vector Machine (SVM) and Classification and Regression Training (CART) Rule Sets combined with other Expert Rules Sets to resolve incorrectly classified issues.....?
- Data Fusion Rule Set-apply other thematic datasets to tweak the analysis by fusing together the three datasets (raster, surface model, and vector) layer arithmetics rule set followed by vector algorithms
- Accuracy Assessment Rule Set?
Thank you
Nadia
