so i’ve recently started using Rstudio using Milos Agathon’s ‘How to Make Amazing 3D Vintage Topo Maps’. I’ve noticed I lose quite a lot of quality when converting my GeoTiff to PNG (timestamp 13:00), and it’s affecting legibility of my maps. PNG left, vs GeoTiff Right

I’ll attach my code below, I wanted to know how I can avoid this?

# 6. RESAMPLE OLD TOPO MAP

africa_topo_resampled <- terra::resample(
  x = africa_topo_tif,
  y = africa_dem_3857,
  method = "bilinear"
)

img_file <- "fourteen_minutes_twenty_seconds.png"

terra::writeRaster(
  africa_topo_resampled,
  img_file,
  overwrite = T,
  NAflag = 255
)

africa_topo_img <- png::readPNG(
  img_file
)
