Thermal Drone Technology

Our thermal drone technology enables real-time detection of heat on surfaces, streamlining inspection processes, reducing labor costs, and providing easily interpretable data for informed decision-making.

360° Tours

Our fast-capture drone photography captures aerial, roof, or ground level imagery to create 360-degree tours that place future development plans in the context of existing spaces, helping you make better decisions faster.

LiDAR

Flexible for use on an unmanned aerial vehicle (UAV) or mobile platform, our advanced LiDAR system facilitates topographic mapping, volumetric analysis, slope stability, shadow analysis, and more.

HyDrone Boat

Our compact unmanned surface vehicle, HyDrone, paired with a portable echosounder facilitates accurate and safe hydrographic surveying even in wet or windy conditions.

Geographic Information System (GIS)

Using geographic information systems (GIS) integrated with Esri software, we develop valuable geospatial mapping tools that enable informed decision-making by incorporating demographic, psychographic, and socioeconomic data into visual representations.

Pipecrawler

Precise and non-invasive pipe crawling surveys ensure accurate identification and measurement of critical project elements in hard-to-access areas—surpassing the accuracy of manual surveys while maintaining safety.

Drone

Our in-house FAA certified drone pilots capture aerial survey photos, quickly model surfaces, and efficiently develop site plans, all of which can be used for everything from facilitating community engagement to construction observation.

3D Scanning

We harness hyper-detailed 3D imagery and incorporate it into critical design software to create 3D as-built conditions documentation that helps designers pinpoint and quickly solve clashes—ultimately saving time and money.

Videography

Engaging videos combine visualizations, drone footage, copy writing, music, and photography to capture each unique project stage from conception to completion.

"ISG is a trusted design partner that solves problems before they arise. The culture of ISG is reflected in the interactions with each ISG team member. The employee owners take an elevated sense of purpose into each client engagement."
