We need to set this protocol down. The disturbance to consider would be flooding, fire or development.

Development - any polygons with pixels within 30m of a built up area in any land cover are filtered. Water - make a worst case water mask using ABMI,NRCan land cover and any polygons with pixels within 30m of this should be filtered

I would make a second filtered site with burnt areas removed (but keep the one with all valid areas as well) Fire - use thr CFS fire database together with any ABMI/Alberta layers - filter out burnt areas after the abandoned date.

Using all the filter (dates and intersections) we have a total of 61885.

When filtering by polygons that weren't disturbed, we end up with 49872

This is without including polygons that can be included if I fix the issue #112
