Hi! Start off by stating I'm VERY new to python, so please excuse my utter confusion.
Here's the deal. I have a model that simulates snowpack, which produces rasters (.tif). The model produces one raster for each day of the year, therefore I have 365 snowpack.tif files. I want to make time-series plots at specific points to compare to actual snowpack data from SNOTEL stations.
Is there a script that can efficiently extract the snowpack value at specific points of all the 365 .tif files, and then export that data (say to a .csv file)?
I have a shapefile of the SNOTEL locations (SNOTEL.shp), which lists the latitude and longitude in the attribute table. I'm trying to figure out a script that will read the rows (the latitude and longitude values) in a SNOTEL.shp file's attribute table, which will then tell the script to extract snowpack values from the rasters (snowpack.tif). The raster's are a matrix, so I may need to convert the lat/long to col/row, but the raster does derive lat/long in the attribute table.
Again, sorry if this is confusing and please ask for clarification where needed. Any advice is appreciated.
