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.; PositionStack the free plan allows only 100 requests per month
  • They diverge on capability: Correlator3D covers Aerial triangulation, PositionStack 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.

PositionStack

  • The free plan allows only 100 requests per month
  • The free plan is a personal licence, so commercial use requires a paid plan
  • The free plan is rate limited, with an extended rate limit only from the Basic plan up
  • Requests beyond the monthly quota are billed as overage, at $0.0003996 per request on Basic
  • The lowest advertised rates require annual prepayment
  • Enterprise volumes are priced by quote with no published rate
