Gtif potential assessment

[lubojr]

Adds Micro Hydropower potential as a new REP5 indicator

Places of potential are simple geometries with a tooltip showing a limited subset of properties from the original data.

following keys are shown:

['ws_code', 'area_sqm', 'flowrate', 'head', 'pr_mw', 'annp', 'gwh_pot', 'z_min', 'z_max', 'z_mean', 'slength', 'min_slope', 'max_slope', 'avg_slope', 'max_sl_nor', 'meanrunoff', 'meanannflo'],

following keys are hidden:

created_at, fid, annp, pr_w, pr_kw

The display style of points utilizes the property gwh_pot setting the circle radius in pixels:

• 5 for gwh_pot between 0 - 1 GWH
• 8 for gwh_pot between 1 - 10 GWH
• 12 for gwh_pot between 10 - 50 GWH
• 16 for gwh_pot between 50 - 750 GWH
• 20 for gwh_pot between higher than 750 GWH

Watershed polygons are shown as a light blue layer for a given potential location after clicking (or touching on mobile) on the location.
