Results for 150m buffers:

eva0marques commented 9 months ago

Steps:

[x] Download 2019 and 2021 NLCD data based on the preexisting function "download_nlcd_data.R". Data stored in /ddn/gs1/group/set/Project/NRT-AP-model/input/nlcd/raw/.
[x] Create function add_nlcd_class_ratio to compute NLCD ratio in buffers around points in SpatVector
[x] Test the function in tests/testthat/test-extract-nlcd-ratio.R (on a few specific points?)
[x] Apply the function to AQS monitors data in vignettes/extract_nlcd_ratio_monitors.Rmd

Question:

should I extract nlcd from nearest or latest published NLCD data? Eg: for 2020, do I get 2021 or 2019?

MAKassien commented 9 months ago

If the data is not present for every year, I would start by downloading the available years and then we can decide how we want to process the years without data (i.e. nearest year, latest year, interpolation of any kind)

Difficulties in opening the .img data downloaded from the USGS website. After further investigation, we think that it is due to .img format storage on the ddn server. The problem is fixed when we use .tif data format, need to convert default .img data to .tif. For now, the conversion is done manually but a new issue (#204) has been opened.
