Experienced Surveyors: Have You Encountered Multispectral Sensing in the Field?
Posted: Wed May 06, 2026 4:20 pm
As drone technology continues to become more integrated into the land surveying profession, I’m curious how many surveyors here have come across or actively used multispectral sensing or other remote sensing technologies in the field beyond standard aerial mapping and photogrammetry.
As I continue studying toward my professional land surveying licensure while working in the industry, I’ve started looking deeper into emerging technologies that may shape the future of surveying workflows once I am fully licensed. Most discussions around UAVs in surveying tend to focus on orthomosaics, topographic mapping, LiDAR, volumetrics, and control workflows. However, multispectral imaging seems to be expanding into areas such as vegetation analysis, environmental monitoring, drainage identification, soil condition assessment, thermal anomaly detection, and even possible site contamination indicators.
While many of these applications are traditionally associated with environmental science, GIS, or agriculture, they appear to be crossing into areas that overlap with surveying, civil engineering, infrastructure management, and construction monitoring. With drone programs continuing to evolve in both public and private sectors, I’m interested in hearing how professionals in the field see these technologies fitting into the role of the modern surveyor.
For those working in public agencies, transportation, utilities, mining, or large-scale development projects:
* Have you encountered multispectral or remote sensing requirements on projects?
* Do you see practical value for surveyors, or is it still largely handled by environmental or GIS specialists?
* Are clients beginning to request these deliverables alongside traditional mapping products?
* How do you think this technology fits into the future role of the professional land surveyor?
I’d be interested in hearing real-world examples, lessons learned, limitations, or even where you think the profession is headed as these technologies continue developing.
