Montreal Island Sewer Manhole Locations And Attributes

Sewer manholes on Montreal Island are placed at maximum intervals of 120 meters in straight sections. The dataset includes attributes like installation date, material, status, and owner, published annually by municipal authorities. Updates made during the year are not included, limiting its use for engineering without validation.

Use Cases

• Map manhole locations and analyze spatial distribution relative to pipe changes in direction, altitude, or slope.
• Examine trends in installation date to understand infrastructure development cycles.
• Categorize manholes by material and status to prioritize maintenance schedules.
• Identify ownership and jurisdiction patterns across the sewer network for administrative planning.

Strengths

• Includes specific engineering rules like the 120-meter maximum interval between manholes.
• Attributes cover multiple dimensions: type, material, installation date, status, owner, and jurisdiction.
• Data is provided in multiple accessible formats including CSV, JSON, and FGDB/GDB.

Limitations

• Data is published only annually, missing intra-year updates which reduces operational accuracy.
• The automated translation of metadata may introduce inconsistencies or errors in field descriptions.
• Lacks concrete metrics like total row count or sample data for assessing scale and completeness.
