DJI L1 LiDAR Drone 

Gromatici has added another drone to our equipment list that performs LiDAR mapping for use in tree covered areas or areas of heavy vegitation.  This drone also has an on-board comera, so we can use photogrammetry to get accurate grades and details on hardscapes and natural ground and use the LiDAR data to get underneath tree canopies for the most accurate topographic basemap posible. 

DJI Phantom 4 RTK with D-RTK 2 Mobile Station Drone system

Call us for a free quote and if your parcel fits certain criteria, we can use our new drone to survey your lot.  

High Definition Laser Scanner (NOVA MS50)

The Leica NOVA can provide a high definition laser scan for your project or we can use it to streamline our data gathering for projects.  This allows us to use the fastest robotic instrument on the market to gather topographic, boundary, and as built data for clients. 

Four GPS RTK units (5 Static)

Gromatici can perform static, RTK, and cell phone modem surveys with our two units.  Our newest GPS is the Leica GS19i, which is Static, RTK, and imaging GPS!

Lieca GS18i RTK Units

With our imaging GPS units, we can capture point clouds and increase the cost-efficiency of our work-flow.  Here we have created a point cloud from imaging to capture trees and utility boxes.  



Gromatici using Carlson Survey with AutoCAD OEM engine embedded.  This allows us to produce licensed AutoCAD DWG files to our design clients, and accept CAD files from them without any issues like in-compatibility. 


This program is designed for surveyors, by a surveyor, and gives us a competitive edge over other local survey firms due to the customized commands that streamline Legal Descriptions, staking of walls, roads, and utilities.  It also uses "Field-to-Finish Technology" that reduces the amount of time drawing up a Topographic Map by 50% to 100% depending on the project compared to traditional CAD programs.
