Blending different data sets
Hello,
I am trying to overlay a set of patches of elevation data obtained by drone survey and SFM to large coverage data similar to Aster. I can import them fine and it all works great but i would need to blend the fine data in the coarse one smoothly and not suddenly as it happens when just overlaying them. Is there such a function or workaround?
Best regards
Michele

You can use the Feathering tab found under Options to blend the edges of your surface(s) with the Aster below.
- Select the layer(s) you want to soften e.g. one or more of the drone surface grids
- Options (at the bottom of the Overlay Control Center)
- Feathering
- Choose a relevant radio button (see bullet list below)
- Set the 'Border Size in Pixels (distance it will feather in pixels - you can go back and change this distance so feel free to experiment)
- If your data is rectangular then choose 'Feather Along One or More Edges'
- If your data is irregular you will need to create a polygon/coverage area to use with 'Feather Within Currently Selected Polygon(s). Just make sure you select it with the Digitizer Tool first
- If required you can export out the final composite surface using File > Export > Export Elevation Grid Format

Thanks a lot.
