Frequently Asked Questions
What's this app purpose?
This application is intended to extract magnetic alignments from geotiff files.
How the alignments are detected?
We use the methodology from Holden et al. (2012). In a nutshell, the pipeline can be describing as follow: calculating the standard deviation, calculating the entropy, calculating the phase symmetry, thresholding and skeletoning.
Why it takes so long to calculate?
First, python (in which this app is written) is slow by itself. Second, as we use a free app-host server, it doesn't have much processing power. If you upload big images, it'll naturally take longer to process.
Why I am waiting so long for downloads?
The app produces the fused Geotiff and Shapefiles on the fly, so the download might take a bit to start due to processing needs. Just keep waiting.
