- Assessing utility easement areas (PM3) for infrastructure planning around the specified site.
Strengths
- Boundaries are defined by official acts with specified effective dates.
- Dataset distinguishes between three distinct regulatory and study phases of a PPRT.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Column-level documentation is absent; field semantics must be inferred after download.
