Basin Analysis Report V2 spec - Fire Disturbance

[jdduh]

The Batch Tool needs to have new analyses that incorporate fire disturbance data. These functions will be integrated into the AOI Summary Tool (#45) as well. The new tools will produce maps and tables (charts) for individual AOIs and a summary .csv file.

Fire Disturbance Tables/Charts

Fire Statistics 1981-current
Fire Statistics 5-year increments up to 30 years (i.e., 2019-2023, 2014-2023, 2009-2023, 2004-2023, 1999-2023, 1994-2023)

• Year (or 5 years)
• Number of new fires for that time period
• Newly burned area
• % AOI area newly burned
• Area of forested land cover newly burned
• % forested area newly burned
• % AOI area with high, medium, and low burn severity newly burned

Fire Disturbance Maps

• Annual / newly burned area on elevation zones
• Annual / newly burned area on land cover
• Annual / newly burned area on other basin analysis report maps (TBD)
• Burn severity of annual / newly burned area on elevation zones

Do we want to implement the maps as multi-pane maps similar to the snodas SWE maps?

[jdduh]

The spec hasn't been finalized but it's very likely that the multi-pane layout is needed.

[lbross]

Are the fire disturbance maps at the same time grain as the charts? This is, will we have 6 versions of each map for: 1981-current, 2019-2023, 2014-2023, 2009-2023, 2004-2023, 1999-2023, and 1994-2023?

Thoughts on not creating maps where the # of new fires = 0, at least for the annual maps? You could generate 40 plus maps that look the same with no fires.

[lbross]

Write the Excel tables to maps_publish\fire_statistics subfolder of the parent directory selected in the GUI. This will be a new subfolder of maps_publish.

[lbross]

Do we want to delete any old .csv files from the fire_statistics directory before writing the new ones? I am testing changing the years/intervals. Right now it overwrites any existing files but won't delete a file if it isn't included in the requested range. We would delete any files with "_annual_statistics.csv" in the file name.

New statistics are added to the spec sheet: https://docs.google.com/document/d/13ip8w16rglsIEex3yszv3FK60vv6Be00DpR9AXLDXJ0/edit?usp=sharing
These new stats are the burned forested areas and percentages with low, medium, and high burn severity data from MTBS.

FYI. NWCC has decided to generate annual reports and time period reports separately using different Report End Year value. Annual reports' Report End Year is the current calendar year (i.e., the latest year with NIFC data). The time period reports' Report End Year is the last year when MTBS data are available. This will prevent time period reports containing misleading statistics caused by the missing MTBS data.
