VerticalGeo spent time this past summer creating road networks for most of the islands in the Caribbean. The screenshots below came from our St Kitts and Nevis Road Network Update Map. You can view our work there on the simple webmap we have posted online. Every year the islands in the Caribbean get slammed with hurricanes and need humanitarian aid to help overcome the disaster. The people of the Caribbean are very resourceful and resilient, and we decided that we could help them by providing updated road network maps.
We started with satellite imagery and began with Open Street Map files of the entire Caribbean. We then took these Open Street Map files and used them to show us where the existing road networks were at. When we came across Open Street Map files that weren’t accurate we updated them. When we came across areas where we saw road networks on the satellite imagery, but no roads documented in Open Street Map, we added the roads. When we came across roads documented in Open Street Map that we did not find on satellite imagery we deleted them from our Open Street Map files. In the screenshot below the purple roads are the road network we created for the country of Nevis.
Here is a close up of the road network of the town of Charlestown in Nevis.
We have completed road network mapping for the following countries:
British Virgin Islands
St Kitts and Nevis
St Vincent and the Grenadines
Trinidad and Tobago
US Virgin Islands
We see this as an opportunity to help out the international disaster relief organizations that need data like this to help plan relief efforts around the world.
Welcome to our second QGIS training video. In this video we will show how to create a point feature shapefile and add cultural landscape icons a small portion of Route 66 in QGIS. We will be adding new videos to our YouTube channel frequently.
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. We use a VerticalGeo proprietary process to determine the location and height of each vertical obstruction, increasing the accuracy and quality of the data we create. 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.

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!
