Format notes

What this previewer is checking.

AGD

Native Ditch Assist import.

AGD files can be loaded directly in Ditch Assist. This page is mainly a visual check for grid points, balance boundaries, benchmarks, and cut/fill direction.

XYZP

Before and after surface.

Four-column files are treated as latitude, longitude, existing elevation, and proposed elevation unless a header says otherwise.

XYZ

Single elevation surface.

Three-column files can show an elevation surface. True cut/fill needs both existing and proposed elevations, so use XYZP or AGD for that check.
