Best way to store location information for data extraction? #1

@7yl4r

Currently, I have ROI information saved in MATLAB format (.mat).

There are two types of extraction for the dashboards (points and polygons). Points are simply a center pixel, which is then "buffered" by a number of pixels to create a box where data is extracted. Polygons are a list of points where data is extracted. Going forward, as we move to using GOM only and potentially going away from MATLAB, in what file format(s) should these points and polygons be stored?

Well Known Text (wkt) seems to be a good standard. Is it easy to read/write .wkt into MATLAB?

I think so. If not, JSON would also be an option.

I have added a file to the repo.

"FK_ROI_WKT.csv"

We can try this to extract values from sat images in the new py workflow when the time comes.

It looks like the "box" extractions are in MULTIPOINT form with corners defined rather then just the center pixel. so, in the WKT file, we have POLYGONS and MULTIPOINTS.

Added a notes file to the repo.
