Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Omeka
- Omeka Classic designed for individual projects rather than large institutional deployments
- Requires self-hosting and technical setup; no managed hosting option in Classic version
- Omeka S pricing not publicly disclosed, available only for download or sandbox testing
- Limited scalability for institutions managing multiple extensive collections
PDAL
- It is a library and command line tool with no graphical interface, so anyone expecting to inspect, edit or visualise a point cloud needs entirely separate software.
- Pipelines are written as JSON with filter-specific parameters, and getting classification results right requires understanding the underlying algorithms rather than tuning a slider.
- Development depends heavily on a small contributor base and on public sector contract funding, which is a concentration risk for an organisation making it load-bearing.
- There is no vendor support tier to purchase; paid help means a consulting engagement, which suits an agency with a procurement process and suits a small firm poorly.
- Error messages and documentation assume geospatial and command line fluency, so the practical adoption cost is staff capability rather than licence fees.
