Cloudpoint Aerial Services is a division of Cloudpoint Geographics, providing professional GIS and mapping services in the fields of surveying, engineering, transportation, utilities, and remote sensing. We are sharing some of our secrets of success to achieving professional, high-resolution aerial imagery using drones that will help you get up and running with your first drone (UAV) flight. This list is not all inclusive but gives you some key points that you will want to accomplish for providing quality aerial services with professional results.
A look back: Cloudpoint's 2014 Year in Review
First Flight: We've come a long way from Kitty Hawk, NC
It's been over 111 years since the birth of powered aviation and its amazing to think of where we've gone. Cloudpoint conducted its first successful GPS-guided aerial mapping test flight on June 9, 2014 at the Roanoke Apostolic Christian cemetery. Height: 150 ft, Speed: 6 mph, Flight time: 8 minutes
Mapping at Sonic Speed
In July we purchased our first company vehicle, a Chevy Sonic, from Sam Leman in Eureka, IL. The logo and lettering by Kat-n-Mouse Graphics of Roanoke. This has been a great vehicle for us as we put many miles on traveling throughout the state to our various clients.
Signs of Success
On May 1 we successfully rolled out our first custom application solution called SignOps, a sign inventory management solution using barcode tags for asset management. LaSalle County was the first project where we tagged over 6,000 signs with barcodes and provided a complete turn-key mangement solution with the SignOps application.
Piecing the Plots together: High-Accuracy cemetery GIS
It's safe to say that the smaller the block, parcel, or lot; the more difficult it can be to accurately represent your features in a GIS system. When it comes to cemetery lots, this can be just the case as we start to go from feet to tenths to inches. If your objective is to just locate a grave with respect to a certain area or section within the cemetery, then maybe a simple smart phone app searching for relative points may be all you need. However, if you need to see the layout of lots, blocks, and graves, using polygons to identify specific graves (which may be the case for cemetery management tools) then high-accuracy GPS is the way to go.
This sample project consisted of collecting cemetery markers with a Trimble Geo-XH 6000 (cm Edition) GPS unit to obtain high-accuracy coordinates which were used as control points to lay out the blocks, lots, and graves or the cemetery. Once the layout was completed, GIS data was populated from an existing database of information obtained from personnel responsible for managing the cemetery. OK, so your next question is "where does the high quality imagery come from?". Google??? NO, this was actually collected with a unmanned aerial vehicle (UAV or commonly known as a drone) outfitted with GPS guidance and a professional grade camera. You can read more about the drone project in separate upcoming blog. The surrounding ground around the cemetery markers was painted with a white "X" to be used as ground control points when stitching the photos together. The final map was served up as a feature service on ArcGIS Server and can be searched by last name using the magnifying glass search tool in the top right corner. Notice how the head stones appear in the aerial image with precise accuracy over their designated grave polygon. There will be more on these tools and methodology to come.
