The short version

  • Only OpenStreetMap has a free tier, so it costs nothing to try first.
  • Each has a real cost: Global Mapper it is Windows only with no macOS or Linux build, so mixed-platform teams end up running a virtual machine and lose graphics performance on large point clouds; OpenStreetMap data accuracy varies dramatically by geographic region depending on volunteer coverage
  • They diverge on capability: Global Mapper covers Format breadth, OpenStreetMap covers Core Functionality.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Global Mapper

  • A survey office that receives lidar in a different format from every client and needs reliable conversion without writing scriptsnot OpenStreetMap
  • A consultancy that wants to classify ground points and extract building footprints from a drone survey without an Esri enterprise agreementnot OpenStreetMap
  • An organisation with an irregular workload that wants to buy the licence outright and skip maintenance in quiet yearsnot OpenStreetMap
  • A geologist producing volumes, contours and cross sections from terrain data on a standalone office workstationnot OpenStreetMap

OpenStreetMap

  • Supplying map data to websites, mobile apps and hardware devicesnot Global Mapper
  • Community mapping of roads, trails, cafes and railway stationsnot Global Mapper
  • Projects that need open map data and can meet the attribution requirementnot Global Mapper
  • Building on map data where a share-alike licence is acceptablenot Global Mapper

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Global Mapper

  • It is Windows only with no macOS or Linux build, so mixed-platform teams end up running a virtual machine and lose graphics performance on large point clouds
  • The interface has grown by accretion over two decades and features are scattered across menus, so new users are slow to find capabilities that are already installed
  • Node-locked perpetual licences are tied to the machine identifier, so a hardware refresh or a failed workstation means a support request rather than a login on a new device
  • Multi-user and web publishing are weak relative to Esri or QGIS with a server stack, so it is a desktop analysis tool and not a platform for sharing data across an organisation
  • Published prices apply to North America and differ elsewhere, so buyers outside that market must go through a reseller and cannot rely on the listed figures for budgeting

OpenStreetMap

  • Data accuracy varies dramatically by geographic region depending on volunteer coverage
  • No minimum quality standards enforced, making data prone to errors and inconsistencies
  • Data completeness gaps, especially for minor roads and remote areas
  • Bias toward well-mapped regions with high volunteer activity
  • Positional accuracy concerns with only 70-76% of roads within 5-10 meter tolerance
  • Tag criteria not well-defined leading to logical consistency issues

Questions people ask

Is Global Mapper or OpenStreetMap better?
Neither clearly leads. Global Mapper starts at $700/one-time and OpenStreetMap at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Global Mapper or OpenStreetMap?
OpenStreetMap has a free tier; the other does not. Paid plans start at $700/one-time for Global Mapper and Free for OpenStreetMap.
Does Global Mapper or OpenStreetMap run on more platforms?
Global Mapper runs on Windows. OpenStreetMap runs on Web, API.
Can I use OpenStreetMap for free?
Yes. OpenStreetMap has a free tier, so you can try it without paying. Global Mapper starts at $700/one-time.
What is Global Mapper best used for?
Global Mapper is most often used for a survey office that receives lidar in a different format from every client and needs reliable conversion without writing scripts, a consultancy that wants to classify ground points and extract building footprints from a drone survey without an esri enterprise agreement, an organisation with an irregular workload that wants to buy the licence outright and skip maintenance in quiet years, a geologist producing volumes, contours and cross sections from terrain data on a standalone office workstation. Of those, a survey office that receives lidar in a different format from every client and needs reliable conversion without writing scripts and a consultancy that wants to classify ground points and extract building footprints from a drone survey without an esri enterprise agreement are not what OpenStreetMap is typically brought in for.
What can Global Mapper do that OpenStreetMap cannot?
Global Mapper covers Format breadth, Lidar processing, Pixels to Points, Coordinate transformation. OpenStreetMap covers Core Functionality, User Interface.

Answered from the vendors’ own pages

Global Mapper: Is there still a perpetual licence?

Yes. Blue Marble sells perpetual node-locked, floating, dongle and network licences that keep working after maintenance lapses.

OpenStreetMap: Is OpenStreetMap free to use?

Yes, OpenStreetMap is completely free and open-source under the Open Data Commons license. You can download and use map data for any purpose.

Source
Global Mapper: What is the difference between Standard and Pro?

Pro is an add-on to a matching Standard licence and carries the lidar classification, feature extraction, Pixels to Points photogrammetry and advanced terrain tools.

OpenStreetMap: How accurate is OpenStreetMap?

OpenStreetMap accuracy varies by region. In well-mapped areas like developed countries, accuracy is generally high. Only 76% of OSM roads aligned within 10 meters of reference roads, with 70% within 5 meters.

Source
Global Mapper: Do I have to pay maintenance?

Only for the first year, which is included. After that it is optional; without it the software continues to run but you receive no upgrades or support.

Global Mapper: Can it replace ArcGIS?

For desktop format conversion, lidar and terrain analysis, often yes. For enterprise data management, web services and organisation-wide sharing, no.
