Surveying and Mapping with Fixed Wing UAS: A Fly-Off Between Leading UAS Providers

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.

ASPRS Technical Presentation February 17 at SLU

The Heartland Region of the American Society for Photogrammetry and Remote Sensing (ASPRS) will hold a technical meeting on February 17 at 4:30 PM at St. Louis University. Details are below:

Title: Better Data, Better Decisions: East-West Gateway’s Spatial Data Enhancement Initiatives

Abstract: East-West Gateway Council of Governments has invested in several datasets to improve geospatial analysis and planning efforts in the St. Louis region. This presentation will showcase investments in orthoimagery, detailed land cover mapping, and wetland mitigation/restoration potential. All of the data presented is available for anyone to use at no cost. Come learn about what we have, how we use it and how you can use it too!

Bio: Jennifer Reiman is the Manager of GIS Services at East-West Gateway Council of Governments, serving the St. Louis region of Missouri and Illinois. Ms. Reiman supports the transportation, environmental and community planning efforts of the Council by providing maps, database reports and spatial analysis services. She earned a B.S. in Environmental Studies & Regional Planning from the University of Kentucky in 2004 and has been at East-West Gateway since 2007.

Location: Des Peres Hall, Room 204, 3694 West Pine Mall, Saint Louis, Missouri 63108

Time: February 17, 4:30PM

Using ArcGIS Online as Part of a Data Collection Workflow

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 LiDAR Tiles: Tug and Barge

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.

New LiDAR Project

Half way done tonight with our 5 week LiDAR classification/cleanup project for the Arkansas Department of Fish and Wildlife. The screenshot below is a 1 mile by 1 mile tile that includes over 8 million points. Airborne LiDAR uses an aircraft equipped with a laser scanner to image the earth’s surface. It doesn’t take color pictures, but takes a snapshot of the earth’s elevation. So the below tile includes a creek running through a culvert under a road. The creek is the lowest elevation and is represented by a magenta color. The road is the highest elevation and is represented by a green color. I enjoy working with LiDAR and the tools you can produce from the data. It just takes forever to process, classify, and clean up.

Using Terrestrial LiDAR for Cultural Heritage Documentation

In July VerticalGeo hosted the ASPRS Heartland Region‘s monthly Technical Presentation. Brittany Mabry, a graduate student from the University of ArkansasCenter for Advanced Spatial Technologies (CAST), presented on “Using Terrestrial LiDAR for Cultural Heritage Documentation.” It was a fascinating presentation that highlighted how Brittany, and the CAST team has used, and taught others to use, Terrestrial LiDAR to digitally capture 3-D imagery of cultural heritage resources around the globe. This is wonderful technology that will allow us to capture and preserve in 3-D those historic places that define our world. Here is Brittany’s presentation:

US National Map Corps

Last week I attended a web-based presentation by USGS on the National Map Corps. I don’t know if you are familiar with USGS’s National Map or not, but it is a great resource for finding and downloading information. I had not heard of the USGS National Map Corps before, so this was good news to me.

USGS has adopted the same editing environment for the National Map Corps that OpenStreetMap has used for a few years (Potlatch). It works well, is simple to use, and they use it to update a few features for the US Topo Map. The features you can currently edit across the US are: schools, fire, police, and EMS locations, state capitals, and cemeteries. Not a lot of features to update, but it is nice to see USGS opening up to crowd sourcing to keep features current and accurate. The updates you make on the map are reviewed by peers and then added to the new US Topo Map quads.
