What is Global Mapper Forum (globalmapperforum.com)?
Global Mapper Forum is the official user community for Global Mapper, the GIS software produced by Blue Marble Geographics. It is a discussion site where roughly 40,000 GIS professionals ask questions, report bugs, and share workflows. It is not a download or purchase page — you go there to get help and compare notes with other users, not to buy or install the software.
Who runs it and who uses it
The forum is operated as the official user forum for Global Mapper, which places it closer to the vendor than a fan-run message board. The community is described as around 40,000 GIS professionals. In practice that means the people answering questions are a mix of other users and Blue Marble staff — several threads show replies from accounts tied to the company, such as a moderator handling a beta announcement and a technical support question.
What actually gets discussed
The board is organized into topic sections rather than one flat feed. From the visible discussion list, the sections include:
- Announcement and News — release and beta notices, plus policy or pricing discussions
- Technical Support — troubleshooting and how-to questions
- Bug Report — reproducible defects in the software
- Suggestion Box — feature requests and workflow complaints
- SDK — scripting and development questions
- Vector Data, Elevation Data, Downloading Imagery, Features Discussion, Other Discussion — data-type and task-specific areas
Threads carry status labels that tell you at a glance whether a question is resolved. You will see tags like Answered and Question, and some answered threads are marked with a check. That labeling is useful when you are searching for a solution: an "Answered" thread is more likely to end in a working fix than an open question.
Examples of the kind of help available
The visible threads show the range of problems users bring here:
| Thread topic | Section | Status |
|---|---|---|
| "Flatten 3D area Features" option greyed out in the create elevation grid dialog | Elevation Data | Answered |
| Curves on a line | Elevation Data | Answered |
| How to popup the setting dialog box when importing a .s file | Features Discussion | Question |
| Max Likelihood Classification of UAV LiDAR | Technical Support | Open |
| Display full length of path profile in Illustrator | Vector Data | Answered |
| How do I thin X,Y,Z data? | Elevation Data | Answered |
| Locked out of World Imagery | Downloading Imagery | Answered |
| Option to open Surpac .str and .dtm files | Suggestion Box | Answered |
| Exporting a geotif raster with overviews/pyramids | SDK | Answered |
| Coordinate transformation bug | Bug Report | Open |
Two things stand out. First, the questions are specific and technical — dialog-box behavior, file format support, raster export settings — which is what you want from a support forum. Second, the answer rate looks healthy: most of the listed threads are marked Answered, and reply counts range from a single response to more than a dozen.
When it is worth your time
Use the forum when you have a concrete Global Mapper problem and want either a fix from other users or confirmation that you have hit a genuine bug. It is also a reasonable place to check before upgrading, since Announcement and News carries beta notices — one visible post announces that a Global Mapper v28.0 Beta is open.
It is less useful if you are looking for:
- Software downloads or licensing — this is a discussion board, not a storefront or download portal
- Pricing decisions — pricing does appear as a discussion topic (one thread is titled "New pricing model thoughts"), but that is user opinion, not an official price list
- General GIS theory — the content is tied to Global Mapper's specific tools and menus
Practical notes before you post
Search the existing threads first, and filter mentally for the Answered label — a large share of common questions already have a resolution attached. When you do post, put it in the right section (Elevation Data, Vector Data, SDK, and so on) and state your Global Mapper version, since dialog options and file-format support change between releases. If you believe you have found a defect rather than a usage question, Bug Report is the section that matches, and a reproducible description is what makes those threads useful to everyone after you.
