I am using satellite imagery data obtained from NEODAAS to record sea surface temperature, salinity, chlorophyll-a/turbidity and thermal fronts around wales over the past 5 years and I have been sent the data as GeoTIFFs and netCDF files. I have inputted the TIFF files into ArcMap 10 and can read and interpret those files no problem, however I now need to find a way to extract individual pixel data values in order to establish parameters at specific coordinates. I am aware that this should be possible in R, however I am unsure if such a package to extract data from a TIFF or netCDF file already exists. I would so hope so as I don’t really want to reinvent the wheel if a programme already exists for such a purpose. Can anyone point me in the direction of such an R package or code? I am using ArcMap 10.4.1 and R Studio version 4.1.0

I am using ArcMap 10.7.1 and I have some GeoTIFF files I have been sent from NEODAAS with some oceanic environmental data. I have managed to add the files as layers and can see them when the scale is 1:1000000 but if I zoom in any further the layer becomes invisible. It is like this for three different environmental variable layers. I have checked in "Properties > General" that the option "show layer at all scales" is selected but the layers are still becoming invisible when zoomed in beyond 1:1000000. Does anybody have any idea as to what the issue might be? I can send screenshots if this will help.
