Create Altimeter Point Plotting Function

[Jack-Hayes]

Hey @scottyhq ! Just wanted to get your thoughts on the below idea after I spent a lot of time messily plotting PCD candidate sites:
Idea to create a quick plotting function for LiDAR extent, stereo extent, and GEDI and ICESat-2 point overlaps. Probably need a separate package 'plot' (ie. coincident.plot.plot_altimeter_points() ?)

Take the results of cascading_search() (and the input GeoDataframe/GeoSeries into cascading_search()) and plot all overlaps onto a small figure with a quick method call.

ie. If you know a 3dep site (variable name gf_wesm) has overlaps, plug it into this function:

• Call the cascading_search() function inside this larger plotting function
• Plot the gf_wesm and gf_stereo extents
• Use the granule names for GEDI and ICESat-2 from cascading_search() to pass into a SlideRule call (to get filtered/quality-flagged ICESat-2 and GEDI points)
  • Not sure if building all SlideRule dependencies into this library is desirable
• Plot the GEDI and ICESat-2 points (ensure same color ramp scale)

This way you can do a quick check if your overlap area contains a satisfactory amount of filtered/quality-flagged ICESat-2 and GEDI points unaffected by clouds and such.

I've gone back and forth on including built-in plots beyond basic geopandas.plot/explore and xarray.plot versus just focusing on search and I/O and leaving all visualizations up to users. On one hand, everyone has different aesthetic preferences and it tends to require many dependencies, on the other, as you mention it's ultimately nice to have a quick visual check of results! Your plan sounds good if you want to open a draft PR!

Yes, I think we should add it #6, I'll wrap that up tomorrow!

Hi @scottyhq ! I'm thinking we can close this issue and focus on flushing out #33 for plotting efforts?

yep, sounds good to me!
