GK Mapping Services · Topography Mapping

Farm topography mapping that shows where water wants to go.

Send GK your RTK data, or let GK work from LiDAR where it is available. The team builds the watershed model and delivers your topography maps in digital format and printed, ready to plan drainage.

Four GK topography maps of one field: aerial boundary, elevation contours, depressions, and color relief elevation

What you get

Move water where it needs to go.

Topography mapping covers two things, the data and the map creation. These maps show you where water wants to go, and help you be much more efficient in getting it there.

See the lay of the land

Elevation maps with contours and color relief show every rise and fall across the field, built from your RTK or LiDAR data.

Find the wet spots

Depressions, hills, and flow paths show where water stands and where it runs, so you fix the acres that need it.

Know your watersheds

Each watershed region is mapped, so you see which areas drain together before you plan tile or ditches.

The deliverables

What your topography maps show.

Real GK topography mapping output for one field, from RTK processing to watershed regions.

GK elevation map of a field with contour lines over color relief
Elevation

Contours and relief

The rise and fall of the field in feet, with contour lines, the base every other map is built from.

GK color relief elevation map of the same field
Color relief

The shape of the field

Elevation shown as smooth color relief, so high ground and low ground read at a glance.

GK depressions map with contours, showing feet below in color
Depressions

Where water stands

Low spots shown in feet below the surrounding ground, the wet spots that need drainage work.

GK flow accumulation map with flow paths over elevation
Flow accumulation

Where water runs

Flow paths drawn over the elevation, showing where water wants to go across the field.

GK watersheds map dividing the field into color coded regions with acres
Watersheds

Which areas drain together

The field divided into watershed regions, each colored and labeled with its acres.

Why GK

35+ yrsIn precision ag
US & CanadaWhere GK works
48 to 72 hrsTypical map turnaround

GK pioneered RTK watershed modeling and in-cab drainage displays, with patented technology behind its SD Drain machine control.

How it works

From elevation data to finished maps.

1

Get the data

Collect RTK data (an RTK quality signal is recommended), or GK works from LiDAR data where it is available.

2

GK builds the model

Watershed modeling turns elevation into a surface drainage map, flow paths, hills, depressions, and watershed regions.

3

Confirm the details

GK may ask you to confirm outlet elevations and the location of culverts and utilities on site.

4

Get your maps

Maps are delivered in digital format and printed, most within 48 to 72 hours.

Pricing

$2.25 / acre

Watershed Modeling, built off LiDAR or RTK data: a surface drainage map, flow paths, hills and depressions, and watershed regions.

Drainage maps may be larger or smaller than tillage acres to give the best product. Most mapping is turned around in 48 to 72 hours. A minimum field size applies. GK does not provide soil sampling, product application, or seeding, and can help you find equipment and service providers if you ask. All prices are subject to change.

Questions

Common questions.

Your collected RTK data, with an RTK quality signal recommended, or LiDAR data where it is available for your area.

A watershed model of the field: a surface drainage map, flow paths, hills and depressions, and watershed regions. Maps are delivered in digital format and printed.

Ask GK about compatibility with your system when you request a quote, and the maps can be delivered in a format that fits.
