The short version

  • Each has a real cost: 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.; GraphHopper the free plan is non commercial use only
  • They diverge on capability: Correlator3D covers Aerial triangulation, GraphHopper covers Core Functionality.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

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.

GraphHopper

  • The free plan is non commercial use only
  • Free allows 500 credits a day, 5 locations per request and a single vehicle
  • Request complexity is capped per plan, at 30 locations and 2 vehicles on Basic at 69 EUR a month, rising to 200 locations and 20 vehicles on Premium at 479 EUR
  • Isochrone range is limited by plan, at 15 minutes on Basic and 30 on Premium
  • Credits are a daily allowance, so a busy day cannot draw on a quiet one
