fmegeotiff-tiffraster-conversion
I was wondering if anyone knows how to convert a raster .tif file into some thing that PCI Geomatica (Focus) can use, such as a .pix or .gpr file?
I have tried to run it through FME, but I cannot seem to come up with a transformer that lets me do it.
Alternatively, does anyone know of a way to open a .tif file in Focus, as it already is in RGB?
This problem is addressed in part by http://blog.hexagongeospatial.com/help-ecw-speckled-edges/
The only way to achieve consistent background color values after compression is by using an AllOpacity band which doesn't appear to be supported by the version of ECWJP2 SDK used in FME.
NeighborFinder will do what you need. New = base, old = candidate. Parameters: 1 candidate to find, distance 5m. The only challenge is to prevent matching the wrong candidate at intersections. Snipping off first and last point of both the base & candidate features should do the job.
======= update 20160620 As Mark suggested adding the AzimuthCalculator should solve the wrong match problem. You need to calculate the overall bearings from both sets, find the matching lines with the NeighborFinder and then test the result based on the difference between the bearings from the matched lines. See added screenshot.
You need to iterate what variables for Distance (NeighborFinder) and difference in bearing (Tester) works the best for your data.

Try using the PCI Geomatics Database File (PCIDSK) format in FME.
That's a raster format that writes .pix files. I don't know that format well enough to be sure, but it seems the logical format to try.
