This is an important acquisition for CSDS, as it will offer California clients a single point of contact for all their precision positioning and workflow optimization needs. With 3 new offices in Ventura, Anaheim and Escondido it will position CSDS as a leader in Trimble Geospatial solution distribution and expand our expertise into innovative surveying solutions such as 3D laser scanning, UAV, mobile mapping and the largest and most reliable commercial real time network surveying networks (RTN) in the Western US.”
