We have been using the free and open source Quantum GIS (QGIS) quite a bit over the last few months. The newest version of QGIS, version 3.0.0 (Girona), has been released and is available for download free of charge here:
It is amazing to see the capability of QGIS these days. If you are just getting started in the GIS world I would start by learning QGIS. If you are experienced in your GIS capabilities then give it a try.
We have been locating, documenting, and mapping vertical obstructions for one of our many customers. As a retired US Air Force C-130 Navigator I flew low level missions at 300 feet almost every day. I know the value of knowing where your vertical obstructions are located before you go fly. We recently worked on an area with an incredible amount of new obstructions. The red dots on the above screenshot represent powerline pylons and the blue dots represent light standards either along roads or within athletic areas. Every dot on the map represents an obstacle that is taller than 50 feet. Most are between 50 and 100 feet, but there are occasional vertical obstructions that reach up to 1,000 feet or more. Those could ruin your fun day of flying whether you are in a C-130 or a Cessna 172. For safety of flight reasons it is imperative to know where these obstacles are. The work we do eventually makes it into FAA and DoD flight charts to help promote safety of flight.
VerticalGeo exhibited at the Society of American Military Engineers (SAME) Industry Day in O’Fallon, Illinois on April 27. We met a lot of great military and civilian engineers and were fortunate enough to listen to the local United States Army Corps of Engineers Districts present their project forecasts for the near future. It was a very informative day with an opportunity to meet a lot of new people and see some old friends. We had so many people come up to our booth and talk about the UASs we had on display. We had a great time.
Exhibiting at the AAAE Airport Geospatial Technologies Conference in Reno this week. Meeting lots of great geospatial professionals all focused on airfields. Only 5 exhibitors here, so a good opportunity to stand out.
Last week we exhibited at the Missouri GIS Conference. We brought our large DJI S1000 Spreadwings UAS with the FLIR Thermal Camera attached to show conference attendees what you can learn from thermal imagery. We had a great time at the conference and met lots of wonderful people. We will see you again next time!
I just came across a great White Paper by Black Swift Technology that compares their Swift Trainer Fixed Wing UAS with the Sensefly Ecobee and the Trimble UX5. Of course, it shows how well the Swift Trainer does compared to the others. Shocker that their study shows it out pereforms the rest! If you are interested in Fixed Wing UAS Technology you should read the comparison.
Here is VerticalGeo’s 2015 Story Map. This map contains an overview of the major projects we worked on for 2015. When people ask what you do sometimes a maps speaks a thousand words. Please feel welcome to share this:

Bethany Marshall is speaking about using ArcGIS Online in our workflow during a Tree Survey we recently completed at the next American Society of Photogrammetry and Remote Sensing (ASPRS) Heartland Region Technical Meeting. Here is a copy of the ASPRS Flyer. So proud of her!
Cleaning more LiDAR tiles today. This one includes a Tug and Barge combination that I found in the middle of the Mississippi River near New Madrid, Missouri. No one will ever know it was there when I get done with the tile. The top view is a cross section elevation and shows what the elevations look like from the side. The bottom view is an overhead look at the Tug and Barge.
Thanks to our friend Brittany K. L. Mabry for putting together a great article on the International Year of Light for LiDAR News. Expect to hear lots of information regarding the use of LiDAR and other light-based technology over the next year. Here is a link to the article:
