You guessed it! It was the 25th Anniversary Blue Marble User Conference.

So, there might be a chance that you haven’t actually heard of this event. That’s ok! I’m writing this to convince you that, whether you are a Blue Marble software user or not, you should know about this conference.

Here are the five reasons why you should join us at the Blue Marble User Conference next year:

Yes, I’m there running around taking pictures and recording video (and eating the food), but what’s more valuable to you are the software developers and resellers who are there to hear your questions and requests.

This particular Blue Marble User Conference was especially valuable because the Global Mapper guru Mike Childs and our international resellers were there. After the day’s presentations and software demonstrations were over, Mike answered questions and heard software  suggestions from attendees while our product manager jotted down the ideas.

It’s a part of Blue Marble’s core values to welcome and encourage users to be part of the development process. That user-to-developer communication is usually in the form of emails, but at a Blue Marble conference, users can communicate directly with the experts and know their ideas will make it to a discussion in our development meetings.

2. You will be inspired by presentations from distinguished GIS professionals

Did you know that scientists know more about the surfaces of Mars and the moon than they do of the Earth’s ocean floor – aka 75% of the world’s surface? I didn’t.

At this Blue Marble User Conference, Larry Mayer, Director of the School of Marine Science and Ocean Engineering and Director of the Center for Coastal and Ocean Mapping at the University of New Hampshire (phew! Long title!), delivered a presentation on the advancements in sonar and visualization technology for exploring the sea floor. He explained how the technology has helped in the discovery of 3,000-meter high mountains in the Arctic, D-day wrecks, the behavior of whales, and the history of climate through the impact of ice on the sea floor. He touted that investing in more ocean research would help us, people of the world, gain a better understanding of our planet.

Ron Chapple, CEO of Aerial Filmworks, discusses his role in the making of the Pulitzer Prize-winning documentary “The Wall”.

Our second keynote speaker and CEO of Aerial Filmworks, Ron Chapple took attendees from exploring the deep with Larry to examining the Earth from above. Ron talked about the challenges that came with producing the Pulitzer Prize-winning documentary “The Wall”, which analyzes the impact of the proposed wall along the border between the U.S. and Mexico. His role in the project was to shoot aerial footage, over which he highlighted the location of the 2,000-mile long border using Global Mapper.

I was surprised to learn how difficult it was for the team of “The Wall” to accurately represent the curvy U.S.-Mexico border in the video.

My point is that BMUC includes amazing presentations by distinguished GIS professionals that give insight into projects that are relevant to the industry today.

3. You will leave smarter and gain Global Mapper “Tips and Tricks”

In between presentations at this year’s BMUC, Senior Applications Specialist David McKittrick took a few minutes to share some “tips and tricks” on how to use Global Mapper. The tips ranged from how to use the multiview display, smooth contours, view data in Google Earth, and create a terrain cutaway.

David also presented on the recent release of Global Mapper 20 and the LiDAR Module, which offers streamlined map layout tools, the ability to create a point cloud from a 3D mesh, a new eyedropper tool for selecting features, dramatically faster loading speeds for working with vector files, and a lot more.

All of these demonstrations were followed by an opportunity for attendees to ask questions that would help them apply these techniques to their own projects.

4. You will eat with other GIS professionals and have a chance to win a prize

Geo-Challenge Tie Breaker

Throughout the day, drinks and snacks were available, and at noon we provided lunch. During lunch, we challenged our attendees to participate in a Where in the World Geo-Challenge, in which they were asked to guess the names of geographic features in a slideshow.

At this year’s BMUC, we came prepared with a tiebreaker question, since we expected that a room full of GIS professionals would easily be able to guess all of the features correctly. The winner of the challenge went home with a gift card to the Blue Marble Emporium.

5. You will spend only $25 to attend

So why wouldn’t you attend BMUC if it’s only $25 for a day full of GIS presentations, networking, and lunch?!

They had me at “lunch”, so … I’m not sure why you wouldn’t register.

Stay tuned for future Blue Marble User Conferences

All jokes aside, BMUC truly has a lot to offer GIS professionals, even if you aren’t a user of Blue Marble software. From the insights of our keynote speakers, to the latest software developments and one-on-one interactions with our experts, BMUC is a great opportunity to connect with Blue Marble staff, have a direct impact on the software you use, and to network with members of the GIS community.

US Fish & Wildlife Service: Global Mapper plays a key role in monitoring coastal habitats of mice

Monitoring a Coastal Dune Ecosystem

Cultivating a sense of moral responsibility for the environment involves more than public service announcements — it’s based on scientific knowledge.

A Peromyscus Polionotus

The U.S. Fish and Wildlife Service works to conserve and protect natural resources, such as species on the federal endangered list, through observing changes in the environment and what those changes impact. As one of the bureaus of the Department of Interior, the agency chooses Global Mapper to assist in this environmental research.

The bureau’s Spatial Ecologist Paul A. Lang specifically monitors the habitat of three subspecies of beach mice:

  • St. Andrew beach mouse (Peromyscus polionotus peninsularis)
  • Choctawhatchee beach mouse (Peromyscus polionotus allophyrs)
  • Perdido Key beach mouse (Peromyscus polionotus trissyllepsis)

The mice inhabit the coastal dune ecosystem along the northern Gulf Coast of Mexico in the panhandle of Florida – an area vulnerable to impacts due to tropical storm events and sea level rise. Lang is interested in gaining a greater understanding of the habitat for the long-term conservation of the beach mice. Lang uses Digital Terrain Models (DTMs) for 2015 in order to investigate sea level changes.

 

A Lack of High Resoultion DTMs

The most important consideration when embarking
on any GIS project is ensuring access to appropriate and clean data.

One of the challenges that Lang has faced in his work is the lack of a high resolution DTMs of the area in which the mice live for certain years. As a solution, Lang accessed publicly available Topobathy LiDAR data from the U.S. Army Corp of Engineers (USACE). This high density point cloud data was collected aerially and was obtained directly from the USACE and from the National Oceanic and Atmospheric Administration’s (NOAA) data clearinghouse.

In order to integrate this data into his research, Lang needed software that had the tools for generating accurate DTMs from the LiDAR data without a steep learning curve.

Raw LiDAR point cloud

Generating DTMs in Global Mapper

Lang chose to use Global Mapper and the accompanying LiDAR Module for his habitat mapping.

With a few simple steps, he generated the high resolution DTMs he needed for his research. First, he imported the .las files into Global Mapper and cropped them down to the area of focus. After visualizing and examining the characteristics and metadata of the point clouds in the software, Lang determined that further classification and clean-up was unnecessary. Second, he examined the inherent statistics of the data to get a better sense of the resolution he could create in the resulting DTMs. Third, he used the Create Elevation Grid tool to generate several DTMs that tested different values of No Data distance in order to fill gaps in the point clouds. After these tests, Lang arrived at high resolution DTMs based on the LiDAR data he obtained from the USACE.

From there, Lang was able to use the Simulate Water Level Rise functionality in Global Mapper to visualize potential water inundation on the mice habitat.

The Benefits of Global Mapper

According to Lang, he chose Global Mapper for his analysis because he didn’t find other software as “straight-forward” for processing LiDAR data. Global Mapper’s easy-to-use platform allowed Lang to quickly and accurately generate the high resolution DTM he needed without taking time away from his research.

Global Mapper allows for easy visualization, editing, and filtering of LiDAR and other point cloud datasets. The addition of the LiDAR Module, expands this functionality with auto-classification tools, automatic and custom feature extraction, point filtering options, and numerous other point cloud editing capabilities.
