Using Global Mapper and Global Mapper Mobile to Prepare for a 186-Mile Bike Ride

After I crossed the finish line of the Trek Across Maine in 2018, I immediately signed up for the next ride without hesitation.

The cycling event takes place over three days and spans 180 miles — starting in the western mountains of Maine and ending on the state’s coast. It benefits the American Lung Association, which is why I chose it as my first cycling event to participate in. I rode in honor of my grandmother who had COPD.

Me in Belfast, Maine after finishing my first Trek Across Maine in June 2018.

When I finished the 2018 Trek, I was so excited that:

  1. I survived!
  2. I got to see a beautiful part of the state I live in
  3. I would be so much more confident on the next Trek because now I knew the route

But then the Trek organizers changed the route for 2019. *womp, womp, womp*

Instead of starting at Sunday River and ending in Belfast, the 2019 Trek would start and end in Brunswick, making a 186-mile loop in central Maine. The route wouldn’t “trek across” anymore, it would “trek around”.

On top of learning about the new route, I hurt my knee badly in January while doing a simple leg stretch (lame!) which was a training-changing injury. So, with a lowered confidence, I wanted to learn more about the new route.

Here’s how I used Global Mapper to visualize and mentally prepare for the 2019 Trek, and how I used Global Mapper Mobile to record my 186-mile journey.

Using Online Data and the Path Profile Tool in Global Mapper

The Trek provides GPX files for each day of the ride on the organization’s website. I downloaded these files; dragged them into Global Mapper; and uploaded elevation data, satellite imagery, and a street map from Global Mapper’s free online data sources.

Using the elevation data, I created path profile views of each of the three riding days. This allowed me to see which of the days would have the largest climbs and where those hills were located. After only a few minutes looking at the data, I could see that Day 2 would be the most challenging. Only ten miles into the 62-mile day, there would be a 375-foot climb, four 225-foot hills, and another 375-footer at mile 45.

Day 1 of the Trek Across Maine
Here’s the elevation of Day 1, the route from Brunswick to Lewiston, Maine.
Day 2 of the Trek Across Maine
Here’s Day 2 from Lewiston to Waterville, which looked like (and proved to be) the hardest day of Trek 2019.
Day 3 of the Trek Across Maine
Here’s Day 3, which appeared to be much easier than Day 2 with only one 250-foot climb at mile 31.

I also explored the “design” of the route by looking at it over satellite imagery to see the vegetation and water bodies I would be riding by. Although Day 2 appeared to be the toughest, it also looked as if it would provide some beautiful views over lakes in the rural Fayette and Readfield area.

Planning Training Rides in Global Mapper

Looking at the path profiles helped me plan my own rides for training. After talking to some cyclists and looking up popular routes in my area, I planned a 28-mile training ride from my apartment in Portland to Gray that included a 375-foot climb — a hill similar to those two big ones on Day 2.

Using the Digitizer in Global Mapper and my online data, I mapped out this training ride, too.

Here is the 28-mile training ride I planned with the computer cursor hovering over the top of the 375-foot climb around mile 10.

Exporting my Map for the Road

In addition to using Global Mapper to look at the path profiles of each day of the Trek, I also used it to add vector points representing each rest stop along the route. After adding these points, I was ready to export my map as a Global Mapper Mobile Package (GMMP) file. Global Mapper 21 and Global Mapper Mobile v2 will allow for a native projection to be retained in a GMMP file. So as I exported, I chose to retain my projection, in my case just for visualization purposes.

I uploaded this file to my Global Mapper Mobile app, and planned on adding data to it while on the 186-mile ride.

Picture Points and the Measuring Tool in Global Mapper Mobile

June 14, 2019 was the first day of the Trek. I had my map in my Global Mapper Mobile app, and I was ready to start documenting my ride!

There are a few ways I could add photos to my map in Global Mapper Mobile. I could create points on my map from geotagged photos, or I could take photos right in the app and add them as attributes to previously existing points. Since I take so many photos with my iPhone camera, I chose to add photos using the Picture Point Create Mode — creating points from photos I had taken outside of Global Mapper Mobile.

Creating a picture point in Global Mapper Mobile
Here are screenshots of the process of creating a picture point on my map in Global Mapper Mobile. I added a photo of my coworker Jeff and me at the second stop on Day 3.

I originally planned on using the app primarily for documenting my ride, but I found it useful in other instances.

When Day 2 really turned out to be the hardest day, I opened Global Mapper Mobile at the third rest stop to see the distance between me and Colby College — the destination of that day. It was a long 21.6 kilometers (13.4 miles) to ride with sore seat-bones and my disappointment in the shortage of fluffernutter sandwiches at this stop.

Using the Measure tool in Global Mapper Mobile
Using the Measuring tool, I figured out how much further I had to go to get to the last stop of Day 2 of the Trek Across Maine.

Global Mapper and Global Mapper Mobile: Easy as Riding a Bike

As Day 2 proved to me, riding a bike isn’t always easy. But GIS software can be!

I am not a GIS professional. I know that editing and exporting a simple map of a bike route isn’t rocket science. But Global Mapper’s user-friendliness made that non-rocket science even easier.

It took just a few minutes of viewing the route with elevation, street, and satellite data to get a better idea of what the 2019 Trek would be like. Even though exporting my Trek map to Global Mapper Mobile was the first time I had used the desktop and mobile apps in tandem, it was a very straight-forward process.

Uploading a map from Global Mapper Mobile to the Global Mapper desktop
A screenshot of the final photo I added to my map in Global Mapper Mobile. It’s a photo of my team and I just after crossing the finish line.

When I returned back to the office after my second Trek Across Maine, I exported my GMMP file from Global Mapper Mobile and imported it to my Global Mapper desktop. I clicked the vector point labeled “Finish Line” with the Feature Info tool, and up popped a photo of me and my Trek Across Maine team.

Immediately after that picture was taken, I signed up for Trek 2020 without hesitation.

Five Reasons to Sign Up for Global Mapper Training

Chelsea E | Projections
Application Specialist Katrina Schweikert leads a Global Mapper training course in Hallowell, Maine in January of 2019.

Blue Marble Geographics offers several training options to help users get the most out of their all-in-one GIS software, Global Mapper: Customized Trainingfor companies or organizations needing tailored instruction based on specific workflow needs; Self-Training, comprised of a series of lessons that users can tackle at home at their own pace; and Public Training courses that cover the extensive functionality of Global Mapper and the LiDAR Module.

While all three options have their benefits, the public training courses, which take place at a variety of locations around the world, come with a handful of perks on top of being great opportunities for users to increase the return on their Global Mapper investment.

In this blog entry, I will list the top five reasons why you should sign up for a public training class, and outline what this training journey looks like.

1. GIS training for both beginners and professionals

Public training molds to the GIS –skill levels and knowledge of the attendees.

A couple of weeks before the class, attendees receive a Getting Started package, which includes the following resources:

  • A PDF of the training manual
  • The data files that will be used in the course
  • Links to the Getting Started Guide and video
  • The Self-Training materials

While it’s not required for attendees to look at these resources, the package gives them the opportunity to see the topics covered in the courses. It also gives attendees time to reach out to Blue Marble’s training team with any specific questions or concerns they may have about the material.

This pre-course communication helps trainers understand attendees’ skills in GIS, ensuring that all attendees get the most out of their individual training experience.

2. Hands-on instruction from GIS experts

In a public training class, Blue Marble’s applications specialists walk through workflows that attendees follow, and provide plenty of opportunities for attendees to ask questions.

Introducing functionality that attendees may not have previously known, this hands-on experience allows trainees to apply new knowledge with real data and in meaningful ways. Their earned skills – ranging from basic Digitizer usage, to more advanced functions such as a variety of terrain analysis functions– can later be remembered and practiced at home with the training manual and data files trainees will take with them.

See the agenda for the Global Mapper class here.

3. A resume builder with an official certification

The complete Global Mapper training course is a three-day program incorporating two separate courses that attendees can sign up for individually or as one continuous program. The first two days are dedicated to the core functionality of Global Mapper, and the third day focuses on the LiDAR Module and point cloud processing.

Individually, the courses are great resume builders, however when, taken together, they earn attendees an official Global Mapper User certification. If an attendee is just starting their GIS-related career, a certificate can be a valuable credential proving their broad range of terrain analysis, 3D data editing, LiDAR processing skills, and more.

4. An introduction to LiDAR and point cloud processing

With increased access to affordable ways of collecting LiDAR and point cloud data, it’s become more important for GIS professionals to understand what to do with this data and to have access to tools that can efficiently process it.

The third day of training focuses on point cloud processing, covering a range of topics, including: LiDAR filtering and editing techniques, photogrammetric point cloud creation, feature extraction, and more. Whether trainees are just starting to use point cloud data, or if they are experienced, this one-day intensive class will cover everything they need to know about Global Mapper and the LiDAR Module’s capabilities.

See the full LiDAR agenda here.

5. A networking opportunity – connecting with GM users

Supplementing the learning experience, the public training courses also offer the opportunity for trainees to meet other members of the Global Mapper user community and to network within the industry. A broad range of professionals – from government workers to UAV pilots– attend and benefit from Blue Marble’s training courses, which makes these courses rich in a different way every time.

Public Training – A valuable GIS experience

Whether it’s to boost a burgeoning GIS career or to re-energize and enrich a mature one, Blue Marble’s public training is a valuable experience that provides insight into the basics of Global Mapper, lesser known software features, certification, and networking opportunities.
