![]() But using the entire dataset as input makes the processing time too long and I figured this would be a way to drastically cut down the time spent on making tables from the NetCDF file and some of the subsequent tools I have to use. Keywords: data format, NetCDF, R, Apologies for the extreme hiatus in blog posts. I've briefly discussed this with one of my academic supervisors who didn't think this was possible in ArcGIS Pro but perhaps with R.Īs mentioned it's a large dataset and I'm planning on using it in the Model builder to produce raster-layers. netCDF (network Common Data Form) is a format of file used for storing multidimensional scientific data (in the form of variables) such as temperature, humidity, pressure, wind speed, and direction. You can do that like this: x <- as.list (rc) s <- sds (x) names (s) <- names (rc) longnames (s) <- longnames (r) units (s) <- units (r) Note the use of longnames (r) and units (r) (not rc ). I tried to read only one of my files and it is working fine, it took about 10 or 15. To write the layers as variables to a NetCDF file you need to create a SpatRasterDataset. ![]() I still need the vertical distribution and the entire time-period, but only for certain areas (that can be defined by lat/lon values).Ĭould it be possible to extract all (vertically distributed) values pertaining to a certain lat/lon point by setting some "extent" or condition for lat and lon values? So that I can extract only a certain spreading in these values while keeping the other dimensions. I have XMS data files from a Scion GC-MS that I converted in netCDF. I am wondering if there is any way to extract data for certain areas based on lat and lon values already stored in the file.

I have a large file (~26GB) containing vertically distributed variable values for a large area of ocean over several weeks.
