Precision Land Surveying Equipment & GNSS Receiver

Join a community of professional land surveyors using Reach devices

Reach RS2 helped our users design a gold mine pit in Alaska. The team surveyed drill collars with centimeter accuracy and exported the results to a GIS app for pit design. Then they used established base points to place GCPs for progress monitoring.

Photogrammetry for a maritime concession in Punta Arenas, Chile, was a challenging project for Kenos Drones. The team used Reach RS2 for RTK land surveying equipment at sub-zero temperatures. They lifted high and low tide lines from the coast of the Strait of Magellan.

Point collection

Collect points, write detailed descriptions, and perform quality control using our responsive interface. The app has built-in support for projections, grids, and geoids and a library with hundreds of verified coordinate systems.

Coordinate systems wizard

Emlid Flow has a wizard for manual coordinate system creation for areas without a predefined coordinate system. To start your survey, you just need to specify the datum, enter transformation parameters or projection, and choose your geoid.

Intuitive stakeout tool

Emlid Flow displays East-North and straight-to-line distances and supports cut and fill indication. When you get close to a point, the indication switches to a close-up alignment mode helping you to center exactly above the point.
Additionally, the app comes with a close-up alignment tool for when you need to be precise.

Fermat Topografia, Costa Rica

With Reach RS2, our users defined initial points for future earthworks in Guanacaste, Costa Rica. They then used the initial points as reference points and ran an RTK survey for volume calculations to verify the amount of removed material. Reach RS2 had great reception even in tight spots.

Jaime Martinez, surveyor, Chile

With Reach RS2, the surveyor placed 200 points to establish farmland properties in San Pedro, Chile. He then imported the dataset to Civil AutoCAD to bring the cadastral plan up to date. After that, he placed stakes with centimeter accuracy to mark the boundaries of each plot.

Grzegorz Krukowski, surveyor, Poland

RReach RS2 helped our user conduct a topographical land survey in Northern Poland woods. Even though the terrain was pretty challenging, the surveyor managed to measure points in places where the sky wasn’t quite visible.

Brent Wiebe, drafting technician, Canada

Using Reach RS2, Brent Wiebe from Canada placed GCPs for a drone mapping project. When the CAD files were finished, our user imported them to the ReachView app for laying out  the project on-site. Ultimately, this helped to approve the construction of a new dairy barn.

Fermat Topografia, Costa Rica

Our users undertook the topographic survey as a part of a floodplain research project. The team used Reach RS2 to determine the deepest areas of the Aranjuez River most likely to be affected by flooding. This dataset helped them create a contour map of potential flood zones.

Vermont Land Integrity, USA

This pair of Reach RS2 was used for a survey in East Montpelier, Vermont. Reach devices are designed to work even in frosty conditions down to -20ºС / -4ºF. These features allowed surveyors to get the job done even in cold weather.
