Example of masked areal interpolation #197

Open martinfleis opened 7 months ago

martinfleis commented 7 months ago

Do we have an example notebook for masked area interpolation? The one using raster. I thought I have seen it before and wanted to share it with a student but can't find anything now. @knaaptime do you have it in some research code available somewhere, at least?

knaaptime commented 7 months ago

dang. the logic is here, but that's all been wrapped into the function now and it doesnt look like i ever pushed up an updated example. Lame on my part. Let me find something for you

I've seen that one but was hoping to find a direct application of masked_area_interpolate

knaaptime commented 7 months ago

yeah i'll grab you one

knaaptime commented 7 months ago

not much explanation here (and it works a lot better with the interactive map), but here's a barebones example https://gist.github.com/knaaptime/7067008cac2837aa131793f0f3f1faca

You're the best! Thanks!

@martinfleis unrelated, but whats up with shapely sending those invalid value encountered in intersection warnings?

GEOS issue that in fact does not affect the outcome. Some of it was fixed in GEOS 3.12 but I'm not sure if all.
