Pros & Cons
Blue Marble Geographics
Pros
- Global Mapper reads and writes more than 300 spatial formats, and none of them need an extra license.
- Lidar classification, cleanup and feature extraction come in a desktop tool that costs far less than enterprise GIS suites.
- The GeoCalc geodetic engine includes more than 12,000 definitions and time-dependent transformations, which suits survey-grade work.
- Since the Avenza merger, field data from the Avenza Maps offline app flows back into Global Mapper for analysis.
Cons
- It is not an asset management or maintenance system. There are no work orders, maintenance scheduling or condition monitoring.
- Licensing has changed recently, and third-party listings show conflicting perpetual and subscription prices.
- Global Mapper is a Windows desktop tool, so collaboration across teams is limited compared with cloud GIS platforms.
O-Calc Pro
Pros
- Wind sweep across all 360 degrees finds the worst-case loading direction without the engineer having to set it by hand.
- Covers many loading codes, including NESC 2023, GO 95, CSA 2020, and AS/NZS 7000.
- Catalog-driven drag-and-drop 3D modeling speeds up building joint-use and make-ready models.
- Photogrammetry measurement tool takes attachment heights and wire sizes from photos.
- The 2024 database add-on adds pole data history and a network connectivity view.
Cons
- No public pricing; both the base software and the add-ons need a quote.
- Covers only pole structures, not general asset maintenance.
- Very few independent user reviews, so the vendor's accuracy and cost claims cannot be checked.
- The database and connectivity features cost extra on top of the base license.
