The short version

  • Only Google Maps Platform has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; Google Maps Platform free allowances are per service rather than pooled, at 10,000 events a month for dynamic maps, geocoding and autocomplete
  • They diverge on capability: Geographic Calculator covers Geodetic parameter database, Google Maps Platform 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.

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.

Google Maps Platform

  • Free allowances are per service rather than pooled, at 10,000 events a month for dynamic maps, geocoding and autocomplete
  • Dynamic Maps cost $7.00 per 1,000 calls at the entry tier
  • Geocoding and the Directions API both cost $5.00 per 1,000 calls at the entry tier
  • Pricing is tiered by volume, so the effective unit price depends on total monthly usage and is hard to predict in advance
  • Billing is usage based with no flat plan, so a traffic spike is a cost spike

Answered from the vendors’ own pages

Geographic Calculator: Is Geographic Calculator the same as Global Mapper?

No. Global Mapper is a general desktop GIS. Geographic Calculator is a dedicated geodetic conversion and datum transformation tool with audit reporting.

Google Maps Platform: How much does Google Maps Platform cost?

Google Maps Platform offers subscription plans starting at $100/month for the Starter plan (50,000 calls), $275/month for Essentials (100,000 calls), and $1,200/month for Pro (250,000 calls). Enterprise pricing is custom.

Geographic Calculator: Can I still buy a perpetual licence?

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

Google Maps Platform: Is there a free tier for Google Maps Platform?

Yes, Google Maps Platform provides a free tier with 10,000 calls per SKU monthly for Essentials and Pro products, plus automatic volume discounts starting at 20% for usage exceeding 100K monthly requests.

Source
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.

Google Maps Platform: What API products are included in each Google Maps tier?

Starter includes Dynamic Maps and Geocoding. Essentials adds Autocomplete, Geolocation, Place Details, Time Zone, Routes, Air Quality, Solar API, and Weather. Pro adds Address Validation, Places Aggregate API, Nearby Search Pro, Text Search Pro, Immersive Maps, Aerial View, Elevation, Route Optimization, and Pollen.

Source
Geographic Calculator: Is there a cloud version?

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

Google Maps Platform: Do new Google Maps Platform customers get any trial credits?

Yes, new customers receive $300 in trial credit toward their Google Maps Platform usage.

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.
