Description
I'm trying to save several images as rasters via drive. Whenever I try, it doesn't give me any errors but returns rasters with only NaN values. The ideal images I want to save are mostly empty with just a few areas with values (clipped to smaller polygons) that are disjoint, but I also tried saving them while clipping to a larger geometry (geeBbox below) and had the same problem.
The issue doesn't seem to be on the earth engine side because I can do Map$addLayer(image) for the version of the images right before I run ee_as_rast(image) and the images look great before conversion.
I'm going to put the simpler code here that just pulls NAIP imagery since that is easier to reproduce, but I have the same problem with some processed Sentinel-2 imagery.
What I Did
#create our focal region (for output geometry, is from a shapefile)
Region <- st_read("../01Data/ChicagoS23/FocalRegion/FocalRegion.shp")
bbox <- st_bbox(Region)
bbox_Poly <- st_as_sfc(bbox)
geeBbox <- ee$Geometry$Rectangle(bbox)
NAIP <- ee$ImageCollection("USDA/NAIP/DOQQ")$
filterBounds(geeBbox)$
filterDate("2019-01-01", "2023-12-31")
#to use to filter the images
randomPts_center <- ee$FeatureCollection$randomPoints(region=geeBbox, points= 100, seed= 0, maxError= 1)
randomPoints <- randomPts_center$map(function(f) {f$buffer(60, 10)})
#get NAIP Imagery
N19 <- ee$ImageCollection(NAIP)$filterDate("2019-08-01", "2019-08-10")$mosaic()$clip(randomPoints)
N21<- ee$ImageCollection(NAIP)$filterDate("2021-09-01", "2021-09-15")$mosaic()$clip(randomPoints)
#switch them to terra rasters
rastN19 <- ee_as_rast(N19, region=geeBbox, via = "drive")
rastN21 <- ee_as_rast(N21, region=geeBbox, via = "drive")
##write the rasters
writeRaster(rastN19, "../01Data/QualityCheck/NAIP_2019.tiff")
writeRaster(rastN21, "../01Data/QualityCheck/NAIP_2021.tiff")
