Abstract
A system and method for generating land maps of a land area. The land maps can include two-dimensional and three-dimensional land maps. The land maps may be efficiently generated based on field data obtained by mobile machines configured to traverse the land area, with the mobile machines associated with one or more sensors. The land maps may be used to accurately and efficiently guide other mobile machines as such mobile machines traverse through or operate within the land area.

A mapping system for generating terrain-adjusted waylines on a two-dimensional land map of a land area, said mapping system comprising one or more computing devices configured to:
- obtain position data for a plurality of locations within the land area;
- generate a triangulated irregular network using the position data from the plurality of locations, wherein the triangulated irregular network comprises a plurality of triangular surfaces representative of the land area;
- project an initial wayline from the two-dimensional land map onto the triangulated irregular network to generate a projected wayline on the triangulated irregular network, wherein the projected wayline comprises a set of one or more connected line segments with each extending across one of the triangular surfaces of the triangulated irregular network;
- generate a parallel wayline on the triangulated irregular network, wherein the parallel wayline comprises set of one or more connected line segments with each being parallel with a line segment from the projected wayline;
- and
- project the parallel wayline from the triangulated irregular network onto the two-dimensional land map to generate a terrain-adjusted wayline spaced apart from the initial wayline.
