People who are interested in using drones for real-world mapping are invited to attend a three-day intensive drone workshop in the Monterey Bay Area. The third annual DroneCamp will be offered June 18-20 by UC Agriculture and Natural Resources' Informatics and GIS Program. No experience with drone technology is needed to participate.
Drone mapping involves taking high-resolution photos with drones and stitching them together with software to make extremely accurate, orthorectified maps. More difficult than videography, it is widely used in agriculture, construction, archeology, surveying, facilities management and other fields. DroneCamp will cover all the topics someone needs to make maps with drones, including:
- Technology - the different types of drone and sensor hardware, costs and applications
- Drone science - principles of photogrammetry and remote sensing
- Safety and regulations - learn to fly safely and legally, including tips on getting your FAA Part 107 Remote Pilot Certificate
- Mission planning - flight planning tools and principles for specific mission objectives
- Flight operations - hands-on practice with both manual and programmed flights
- Data processing - processing drone data into orthomosaics and 3D digital surface models; assessing quality control
- Data analysis - techniques for analyzing drone data in GIS and remote sensing software
- Visualization - create 3D models of your data
- Latest trends - hear about new and upcoming developments in drone technology, data processing, and regulations
On the first day, DroneCamp instructors will discuss drone platforms, sensor technologies and regulations. On the following two days, participants will receive hands-on instruction on flying safely, using automated flight software, emergency procedures, managing data, and turning images into maps using Pix4D mapper and ArcGIS Pro.
Registration is $900 for the general public and $500 for University of California students and employees. Registration includes instruction, materials, flight practice and lunches. Scholarships are available.
This year DroneCamp is being held in conjunction with the Monterey Bay DART (Drones Automation & Robotics Technology), which is holding an industry symposium on Friday, June 21. DroneCamp participants get a $50 discount to attend the symposium.
In the late 1800s, when automobiles started replacing horses in the United States, farmers were likely pondering how the new technology could be adapted for agricultural production. Before long, tractors revolutionized the industry.
A similar scenario unfolded in June at a UC Cooperative Extension field day in Merced County. Farmers, scientists and entrepreneurs gathered at Bowles Farm in Los Banos to learn how drones may be deployed on farms of the future to improve irrigation, fertilization and pest management practices and monitor the crop to maximize yield and profit.
Instead of driving a pickup truck around the perimeter of the field, pushing through hip-high row crops, or meticulously sampling dozens of tree leaves, a quick fly-over with the right equipment could provide farmers all the data they need to make production decisions.
This won't happen tomorrow. Regulations still hamper drone use and the cost of some equipment is prohibitive. But UCCE advisor David Doll is working with scientists at UC Merced and Fresno State to find low-cost alternatives for data collection and analysis that will make the information collected by drones of value to farmers.
“We were able to get good correlation with plant water stress using a thermal camera, however the platform is too expensive,” Doll said.
Doll's research, funded by a grant from UC Agriculture and Natural Resources, uses data from hundreds of drone flights over an almond orchard. The project has shown that monitoring perennial cropping systems from the sky presents challenges.
“Perennial crops will have water stress before the crops show stress,” Doll said. “We need to find an algorithm to identify water stress before it's too late for the orchard.”
Bowles Farming Company, which hosted the field day, flies drones over its farms three days a week, said Justin Metz of the company's technology integration team. The high-definition imagery is shared with the on-staff agronomist, who can diagnose emerging issues.
“Our use of drones is in its infancy, but we're ahead of others,” Metz said. “Knowing the capabilities is really exciting. Drones are here, and they're going to stay.”
UCCE agronomy and weed science advisor Lynn Sosnoskie attended the drone field day to gather ideas and make contacts. She believes drones have the potential to monitor crops for herbicide injury.
“I want to ground truth drone images to see if they can predict yield loss,” Sosnoskie said.
Retired pest control adviser Richard Stewart, one of about 100 attendees, is considering how drones could be used to monitor for rodent damage in irrigation ditch banks.
“I've never see anyone do that,” he said. “I'm just looking into it. It's a new idea.”
The drone fly is an identity thief. It's often mistaken for a honey bee. Hey, isn't every floral visitor a bee? No, not by a long shot. One's a fly and one's a bee. That came to mind last weekend when we saw a large number of honey bees (Apis mellifera) and drone flies (Eristalis tenax)...

Pull up a chair and engage in a little "girl-watching." That is, honey bees heading home to their colony. Many beekeepers, especially beginning beekeepers, like to watch their worker bees--they call them "my girls"--come home. They're loaded with pollen this time of year. Depending on the floral...

Beekeepers sometimes see a white-eyed drone in their hives--a genetic mutation.All drones (male) honey bees, have these spectacular wrap-around eyes that are perfect for finding a virgin queen on her maiden flight. After all, the drone's sole purpose is to mate with a queen and then die. So, every...
