Tree Canopy Classification – Vanderbilt University Campus Nashville Quantifying tree canopy cover across expansive areas has historically been a time-consuming endeavor, often reliant on labor-intensive field surveys or manually analyzing traditional aerial imagery. Such methods are not only cumbersome but also prone to error. Through the innovative application of Unmanned Aerial Vehicle (UAV) technology, significant […]

UAV Vertical Asset Inspection: Techniques and Benefits
Vertical assets such as communications, tall buildings, or water towers are difficult and dangerous to inspect. For this reason, UAV technology is quickly becoming the preferred method of vertical asset inspection. Three primary reasons UAV inspections are becoming prominent are safety, time savings, and superior documentation; these are just some of the immediate benefits we […]
Multi-Rotor vs. Fixed Wing UAV Platforms: Considerations for Evaluating Capabilities and Limitations
Using the correct equipment is critical to the success of any project. UAV projects are no different, knowing how to select the best tool for each specific application is fundamental to efficient data collection. We use both multi-rotor and fixed wing UAV equipment, depending on project goals and constraints. Below are some considerations for selecting […]
Change Your Point of View With Photogrammetry
Photogrammetry is the art, science, and technology of obtaining reliable information about physical objects and the environment through processes of recording, measuring, and interpreting photographic images and patterns of recorded radiant electromagnetic energy and other phenomena (Wolf and Dewitt, 2000; McGlone, 2004). How does Photogrammetry work? Triangulation is the basis on which all photogrammetry is […]
Why “Drone” Is a Dirty Word: The Difference Between Drones and Professional UAV Equipment
Common terms and abbreviations: UAV = Unmanned Aerial Vehicle sUAS = small Unmanned Aircraft System (less than 55lbs) RTK = Real Time Kinematic, high accuracy gnss positioning using local controls for correction and validation. GNSS = Global Navigation Satellite System(GPS-United States, BeiDou-China, Galileo-Europe, GLONASS-Russia) Photogrammetry = science and technology of making measurements using photographs. This […]
GEO Jobe Welcomes Reed Davis as UAV Business Development
GEO Jobe is pleased to welcome Reed Davis as our new UAV Business Development lead. Previous to GEO Jobe, Reed was a GIS Analyst at the City of Biloxi in the Engineering Department. While at the City of Biloxi, Reed worked on processing LIDAR, developed databases and management for ArcGIS servers and SQL servers. In […]
State of the Drone
Winding down the year is a good time to reflect on the changes, applications, and direction of the small Unmanned Aerial Systems in the mapping industry. This has been another year of rapid and dramatic changes in the drone world. Waivers and authorizations are still big topics. Drone for delivery is creeping into the picture […]
Sharing (GIS Data) is Caring
Sharing data can be a touchy subject. In general, it seems that people and institutions do not like their research and findings being freely accessible to the public. If you have worked on any project requiring data you could not collect on your own, you have more than likely jumped onto the World Wide Web […]
Case Study: GEO Jobe UAV and the Sandestin Owners Association
It is not uncommon for organizations to supplement their GIS data with aerial imagery captured from a manned aircraft or drone. This perspective may come as an after-thought to some, being procured after a GIS program has already been established; however, for the Sandestin Owners Association, aerial imagery came before their GIS. Three years ago, […]
Making the point with UAV
A question came up recently in a conversation about the different products and stages of processing and presenting data captured by UAVs. I’ll use a recent construction monitoring project to demonstrate some nice examples of the various stages of the photogrammetric processing workflow. This will also show and describe some of the products and deliverables […]
