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.
PPLS-CADD
Pros
- Bentley says it is used by more than 1,600 organizations in over 125 countries, and the acquisition announcement called it the US industry standard for transmission line design.
- Combines terrain modeling, sag-tension and thermal ratings (IEEE 738 and CIGRE 207) in one tool.
- Imports and classifies large LiDAR point clouds, and its AMBER tool builds line models from them automatically.
- Plan and profile drawings regenerate automatically when the design changes.
- Links directly to PLS-POLE, TOWER and the SAPS finite element engine for structural checks.
Cons
- No public pricing; buyers must request a quote.
- Bentley recommends about five days of training, so new users face a steep learning curve.
- Runs on Windows only.
- Covers design only: there are no work orders, maintenance or field inspection tools.
