Our clients have a choice. Utilities, municipalities, and consultants use Westwood's Scale-Accurate Digital Imaging (SADI) and LiDAR solutions for site and infrastructure studies, facility design, right-of-way records, environmental support, and operations and maintenance functions. Every project is unique and there are distinct advantages to each technology. We help our clients to choose the best solution to meet their aerial mapping needs.


Aerial photo-based, ortho-corrected imagery and feature-coded digital terrain model data that is geo-referenced, highly-accurate, and scalable.

SADI is best when a wide corridor of data is required for routing new lines and allow for potential re-route options. SADI provides the ability to deliver imagery and/or terrain data up to two miles wide in one flight pass; which allows T&D designers the ability to assess multiple corridor options, study planned ROW access, and adjust routes without added flights.  


High-density, geo-referenced points for fast acquisition and processing of high-accuracy data using the latest, state-of-the-art technologies.

LiDAR is recommended when heavy detail of existing conditions is needed for upgrading existing lines or identifying clearance issues. The data provides an in-depth look at existing features, which allows for infringement identification and vegetation management. LiDAR is preferred in areas containing dense vegetation or above-ground obstructions .
