The 3D PAWC and constraints mapping project utilised R to create software pipelines that process field boundaries, access privately available proximal surveys, and download private and publicly available terrain and climate data. These datasets are stored as a datacube which is used in the following 3 steps of the project: producing a stratified random sample design, summarising lab analysis results to report to growers, and running an automated modelling process to map soil properties. 
Within each section, there is a working script that can run on a predefined farm from the project. 

Sample design: This pipeline transforms the compiled datacube into strata across a farm and then randomly samples these strata given a predefined sample size. The R code can be made available for this summary reporting process, subject to an agreement with the University of Sydney and the GRDC.
Models and mapping: This pipeline extracts covariates from a farm's datacube to the point locations of lab analysis sites. For any measured soil property, several models are compared for prediction quality over analysis depth intervals (0-15 cm, 15-30 cm, 30-60 cm, 60-100 cm). The best performing model is selected for each soil property and used to produce maps across the sampled fields of the farm. The R code can be made available for this automated modelling, subject to an agreement with the University of Sydney and the GRDC. 
Files are stored in .rmd format and require input from .csv files.


The software pipelines are stored on the USYD-RDS at \\shared.sydney.edu.au\research-data\PRJ-MLCons. Data access is restricted as the code links to private APIs with access to restricted and sensitive private farm data. Third-parties will need to request access from GRDC and the University of Sydney, subject to a data supply and/or licence agreement
