Plan the route before the shovel hits the ground.

Draw a field, keep management zones separate, generate durable sample and core IDs, collect with GPS, and leave the field with a laboratory-ready audit trail.

Mapped

Lab samples

Collected

Draw

Trace or import the actual field boundary.

Design

Choose composite, grid, or management zones.

Collect

Navigate, record GPS, and export the audit trail.

Field setup

Use the polygon/rectangle tools on the map. Multiple polygons remain separate zones and samples.

-- acres mapped across 0 zones (0 polygons).

Estimated: 0 lab samples / 0 cores.

Map tip: zoom in before drawing. Use edit to tune vertices and the trash tool to remove one polygon.

The PDF includes the field map with sampling points, a field sheet, route table, bag labels, flags, and evidence notes. GIS exports preserve planned and actual coordinates.

The planner preserves this hierarchy in every export, preventing unrelated zones or samples from being flattened into one result later.

Evidence layer

Defaults are prompts, not universal rules.

Representative areas, consistent depth, multiple cores, careful labels, and separate atypical areas are durable principles. Exact counts, spacing, depth, timing, handling, and grid intensity must follow the selected laboratory and local protocol.
