The short version

  • Only Atlas.co has a free tier, so it costs nothing to try first.
  • Each has a real cost: Atlas.co analytical depth is a long way short of a mature GIS: there is no serious raster analysis, network analysis, topology editing or geodetic control, so complex work still goes back to QGIS or ArcGIS.; Correlator3D the standard licence caps at 61 megapixel sensors, so an operator moving to a medium or large format camera has to buy a different and separately quoted licence rather than paying an upgrade fee.
  • They diverge on capability: Atlas.co covers Browser GIS, Correlator3D covers Aerial triangulation.
  • 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.

  • A planning or property team that mainly needs colleagues to view and comment on maps, where $7 viewer seats replace expensive read-only GIS licencesnot Correlator3D

Correlator3D

  • An aerial survey company processing large photographic blocks where per-project cloud credits would be more expensive than owning a licencenot Atlas.co
  • A national or regional mapping agency that needs software it can run offline on classified or restricted imagerynot Atlas.co
  • A drone service provider producing bare-earth terrain models for volumetrics and corridor mapping at high throughputnot Atlas.co
  • An organisation that wants a perpetual licence because a multi-year subscription cannot be justified against its capital budgeting rulesnot Atlas.co

Where each one falls short

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

Atlas.co

  • Analytical depth is a long way short of a mature GIS: there is no serious raster analysis, network analysis, topology editing or geodetic control, so complex work still goes back to QGIS or ArcGIS.
  • Geocoding and workflow runs are metered per tier, and a single large address batch can exhaust a month’s Pro allowance in one afternoon, forcing an upgrade for a one-off job.
  • The company is at pre-seed stage with roughly $2m raised and a small team, so buyers embedding it in a business process carry meaningful continuity risk.
  • Annual billing is required to get the advertised prices, which removes the flexibility that would otherwise make a young vendor a low-risk trial.
  • There is no offline or field capability at all, so any organisation whose spatial work includes data collection needs a second tool alongside it.

Correlator3D

  • The standard licence caps at 61 megapixel sensors, so an operator moving to a medium or large format camera has to buy a different and separately quoted licence rather than paying an upgrade fee.
  • It is Windows desktop only with no cloud processing option, so throughput is bounded by the workstation and GPU you buy, and there is no way to burst capacity for one large job.
  • There is no collaboration layer, client portal or field application, so deliverable sharing, review and version control all have to be handled by other software.
  • The interface and workflow are built for photogrammetry specialists; an occasional drone operator will find the learning curve steeper than a consumer-oriented mapping package.
  • The perpetual licence includes only one year of support and updates, and staying current afterwards means paying maintenance, so the headline $5,900 is not the whole long-term cost.
