Alberta Provincial 1:20,000 National Topographic Grid

2838 complete and 269 partially complete 1:20,000 National Topographic System (NTS) grid blocks cover the province of Alberta. The grid was developed for the Provincial Digital Base Mapping Project, with each polygon designated by a structured alphanumeric code (e.g., 83H08NE). It is produced for the Government of Alberta and made available to the public.

Use Cases

• Map Alberta's 1:20,000 NTS grid blocks using their structured polygon designations for spatial indexing.
• Analyze the distribution of complete versus partially complete NTS blocks across the province.
• Integrate the 1:20,000 NTS grid with other provincial base mapping data using the polygon quadrant labels.
• Support cartographic projects by referencing the standardized 1:20,000 NTS block labeling system.

Strengths

• Covers the entire province of Alberta with 2838 complete grid blocks.
• Includes 269 additional partially complete blocks for boundary areas.
• Provides a standardized national mapping reference grid based on latitude and longitude.

Limitations

• The 1:20,000 grid is not part of the formal Natural Resources Canada NTS program, potentially limiting national interoperability.
• Sample data and specific column schema are unavailable, complicating initial data inspection.
