The short version

  • Only Cesium ion has a free tier, so it costs nothing to try first.
  • Each has a real cost: Cesium ion streaming is metered in gigabytes a month, so a public-facing application's cost is driven by visitor traffic you do not control, and a successful launch can blow through a tier immediately.; 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
  • They diverge on capability: Cesium ion covers 3D Tiles tiling, Global Mapper covers Format breadth.
  • 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.

Cesium ion

  • A survey firm delivering a photogrammetry mesh to a client as a browser link rather than a 40 GB downloadnot Global Mapper
  • A simulation team streaming global terrain and imagery into an Unreal Engine environmentnot Global Mapper
  • An urban planning department publishing a city model that planners can inspect without desktop GIS softwarenot Global Mapper
  • A software product embedding 3D geospatial views and needing hosted tiling rather than building a tilernot Global Mapper

Global Mapper

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

Where each one falls short

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

Cesium ion

  • Streaming is metered in gigabytes a month, so a public-facing application's cost is driven by visitor traffic you do not control, and a successful launch can blow through a tier immediately.
  • Reality modelling is billed in gigapixels a month, an unfamiliar unit that makes it hard to estimate in advance how many drone flights a plan will actually cover.
  • The free Community tier is restricted to non-commercial or open use, so a consultancy sharing a model with a paying client does not qualify regardless of how small the dataset is.
  • Team accounts cost substantially more than individual ones at the same quota, $524 against $149 on Commercial, so adding a second colleague is a large step rather than an incremental seat charge.
  • Self-hosting is available only under a custom enterprise agreement, which leaves organisations with data residency or air-gap requirements out of the published tiers entirely.

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

Answered from the vendors’ own pages

Cesium ion: How is Cesium ion priced?

By several meters at once: storage in gigabytes, streaming in gigabytes per month, and reality modelling in gigapixels per month. Commercial starts at $149 a month for an individual.

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.

Cesium ion: Is the free tier usable commercially?

No. Community is for non-commercial or open use. Commercial work needs a paid plan.

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.

Cesium ion: Can I run ion on my own infrastructure?

Only under a custom enterprise agreement negotiated with Cesium.

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.

Cesium ion: Do I need Cesium ion to use CesiumJS?

No. CesiumJS is open source and free. ion provides hosted tiling, base layers and streaming that you would otherwise have to build.

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.
