The core pattern shows on the map as small marks around each point so whoever is pulling the sample walks the same shape every time.

Numbering & route

Order

Start number ID prefix

Start from points you already have

Re-sample the same holes as last year, or take a layout somebody else laid out. A CSV needs Lat and Lon columns; a point shapefile works as it comes. Imported points arrive locked, so a regenerate leaves them alone.

CSV Shapefile

Skip points that fall outside this field’s boundary

Build

Generating replaces every unsampled, unlocked point. Points already sampled, and any you have locked, are kept where they are.
