Where each one falls short

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

Geographic Calculator

  • No pricing is published for any edition, so buyers negotiate blind and the perpetual versus subscription decision is made without a public list to anchor against.
  • Licence mobility is tied to being current on maintenance and support, which means a customer who lapses maintenance on a perpetual licence cannot move it to a new machine, effectively turning a perpetual purchase into a recurring cost.
  • It is a transformation engine, not a GIS: there is no meaningful analysis, cartography or editing, so most buyers end up also owning Global Mapper and paying twice for overlapping data handling.
  • The desktop product is Windows only, which is awkward for organisations standardised on macOS or Linux geospatial pipelines despite the cloud option covering only part of the workflow.
  • Blue Marble acquired Avenza in 2026 and is integrating a field data collection product, so engineering attention is spread across a wider portfolio than when Geographic Calculator was one of two products.

Foursquare Places API

  • Premium endpoint features like photos and ratings require paid calls with no free option
  • Entry-level free tier ($200/month) may be insufficient for high-volume applications
  • Limited real-time update frequency compared to enterprise solutions
  • Requires API key management and developer portal familiarity

All developer accounts receive $200 per month in free usage credits. After these are consumed, pay-as-you-go pricing applies. Pro endpoints have 500 free calls monthly, while premium endpoints have no free tier.

Yes. Blue Marble offers perpetual as well as subscription licensing, but a perpetual licence can only be moved between machines while maintenance is current.

Foursquare Places API: What data does Foursquare Places API provide?

Foursquare provides a dataset of 100M+ places across 200 countries with 50+ attributes per place, including venue details, categories, hours, ratings, photos, and tips.

Geographic Calculator: Why not just use QGIS or PROJ?

For routine reprojection they are fine. Geographic Calculator is bought when the transformation path, its accuracy and a documented audit trail must be defensible to a client or regulator.

Foursquare Places API: What are the pricing tiers for premium endpoints?

Premium endpoints like photos, tips, hours, and ratings cost $18.75 per 1,000 calls with no free tier available. Pricing scales with usage.

Geographic Calculator: Is there a cloud version?

Yes, Geographic Calculator Cloud provides browser access to the transformation catalogue.

Geographic Calculator: What changed with the Avenza acquisition?

Blue Marble acquired Avenza Systems in 2026, adding Avenza Maps mobile field data collection to the portfolio. Ask about roadmap commitments before signing a long maintenance term.
