I would like to explore the texture information in several SAR images. I plan to use the following workflow:
- Apply orbit file (only for Sentinel-1 images)
- Calibrate (to gamma, to correct for the effect of incidence angle)
- Deburst (only for Sentinel-1 images)
- Terrain correction
- Data conversion
- Mask (I am only interested in a certain part of the images)
- GLCM (texture analysis)
My main question is the following: I want to scale every image between 0-255, before the relative step of GLCM texture analysis. For 0 I want to use a certain value (let’s say -19dB) and for 255 another (-10dB). I want to have this specific range for all the SAR images. Can I use the Convert Datatype operator to do so? I cannot find where to specify my min. and max. values if I select ‘Truncate’. Could anyone help me with this?
Furthermore; do you think this workflow is appropriate for texture analysis?
Thank you in advance!
