The Right Tools Saving Time and Money!

Ever been in the situation where you’re working on a task without all the information at hand? It’s a much more difficult job! GM Tree Consultants found this when they came to carry out BS5837 surveys on developer sites where there were trees present requiring much more detail than was possible with their current kit.

Consulting with MGISS, the Arrow 100 GNSS receiver with GeoGrafi-M and Keytree was identified as a toolkit that was going to allow them to plan and map accurately whilst being cost effective. The Arrow 100 is a GPS/GNSS receiver manufactured by Eos Positioning Systems and distributed in the U.K. exclusively by MGISS.

The Arrow 100 is designed to be strapped to a utility vest, a backpack, a nylon pouch or a rangepole. It can capture high accuracy location metadata in the field. It can then communicate this data, accurate to within a metre, to the GeoGrafi-M software via Bluetooth. GeoGrafi-M runs on Windows, Windows Mobile and Android and is capable of delivering positional accuracy from 1m to 1cm in real time onto your survey drawing or GIS layer.

Gary Marsden, Director and Principal Tree Consultant of GM Tree Consultants said:

“I’m getting high quality results which has improved my efficiency and productivity. I also use Keytree which enables me to combine collecting the data in the field with producing accurate CAD drawings.”

“I can complete the BS5837 surveys in the required detail in less time and I also now have the equipment to speed up surveying VTA and mortgage surveys, which allows us to be more productive. The products are all compatible with each other and I feel that in taking this step I’ve taken measures to futureproof my business.”
