Examples for doing spatial analysis with R in CSC computing environment:
- roihu - examples for different job types in Roihu: simple serial, array and parallel:
snow,parallelandfuture. - Working with Allas data from R
- Reading NLS topographic database geopackage with R
- R for LiDAR data - examples and exercises
- Some R packages have in-built support for parallization, for example
terraandlidR.- lidR
terra- mainly follow terra manual. Withterrait is important to set memory settings manually, because by default it does not understand memory availability on supercomputers correctly. For example if reserving 8Gb memory from batch job, tell it also toterra. Adjust also used memory share, the default is 50%.
terraOptions(memmax=8)
terraOptions(memfrac=0.9)
