Shiny, assign index class, more checks

[leppott]

Is your feature request related to a problem? Please describe.
More checks on station in the assign index class file builder function in Shiny.

• Level 3 ecoregion check. flag sites outside these ecoregions: Coast Range, Puget Lowland, Willamette Valley, Cascades, and North Cascades.
• Xeric region check. Flag sites with mean annual precipitation < 650 mm (based on StreamCat PRISM 1981-2010 local catchment scale data)
• ICI/IWI. No flags for now. Just something I’ll want to plot to check anomalous results (samples that have BCG outputs better or worse than expected based on ICI and IWI scores)

Additional context
Not sure if have the information to compare or will need to generate.

[leppott]

Only require SiteID, elev_m, and pslopeNHD.

With a GIS layer can assign Level 3 ecoregion in the get parameters section.

Annual precip will need to get info from StreamCat.

Not sure where ICI and IWI info is obtained.

[leppott]

Level III ecoregions
1 = Coastal Range
2 = Puget Lowlands
3 = Willamette Valley
4 = Cascades
77 = North Cascades

[leppott]

StreamCat PRISM 1981-2010 local catchment scale data

FINAL_TABLE = PRISM_1981_2010
METRIC_NAME = Precip8110[AOI] (units are mm)

[leppott]

ICI and IWI also available using StreamCatTools

[leppott]

Ecoregion would need to extract from a shapefile using provided lat-longs.

[leppott]

Only ecoregion left to implement.
