Shaping Cambodia through accurate surveying.
Since 2015, EZ Surveying Co., Ltd. has built the geospatial backbone behind Cambodia's most ambitious infrastructure, urban and natural-resource projects — combining world-class technology with deep local expertise.
From a single office to a national geospatial platform.
EZ Surveying began with a simple conviction: Cambodia's rapid growth deserves world-class spatial data. What started as an equipment supplier in 2015 has grown into an integrated platform — instruments, CORS infrastructure, drone services, software and a training academy.
Today our teams work alongside government agencies, engineering firms and developers, delivering the precise measurements behind highways, bridges, smart cities and the irrigation systems that feed the nation.
Our Mission
To empower Cambodia's engineers, surveyors and decision-makers with the most accurate, accessible and modern geospatial technology — from instruments to infrastructure to people.
Our Vision
A Cambodia where every road, building, farm and natural resource is mapped with centimeter precision — enabling smarter planning, safer construction and a digital future built on trustworthy data.
The principles that guide every project.
Accuracy
Every measurement matters. We hold ourselves to international survey standards on every project.
Integrity
Transparent delivery, honest reporting, and accountability from quotation to handover.
Innovation
We bring proven global geospatial technologies to Cambodia first — and adapt them to local needs.
People
We invest in the next generation of Cambodian surveyors, engineers and GIS analysts.
