bloom frequency #12

Closed aignatius closed 5 years ago

aignatius commented 7 years ago

As a developer, I would like to create a coverage of bloom frequency for each cyan pixel so that I can identify areas with frequent cyanobacteria blooms.

Acceptance criteria: given a set of geotifs, I would expect a heatmap spatial coverage output showing how often bloom occurring at each pixel location.

Start with GEE script "03MERIS_pixelMax_ImageCollection". Create new script to calculate percent of geotifs where cells/mL > 19,999

Completed script to generate cyan bacteria frequency heatmaps. Able to specify thresholds of 'low' (cell/mL < 19,000), 'moderate' (cell/mL > 19,000 and < 99,999), 'high' (cell/mL > 99,999), 'low moderate' (cell/mL < 99,999), and 'moderate high' (cell/mL > 19,999). Outputs a geotiff of the result image.
