Tenth DIFMR meeting. Another example of trial design, in a more challenging field, was presented. Most of the process is the same as shown before, but instead of using a single AB line, all the path lines must be available. The field was split into three parts to make the blocking easy and was merged together to produce a single map in the end. The last part was a demonstration of the functions being developed to integrate the package with a PostGIS database to store all the spatial data.
