NAD83(CSRS)v7 Epoch 2010 ASCM: Alberta Survey Control Points

32,971 published ASCMs provide coordinate and elevation data for Alberta's survey control network. The geographic coordinates are referenced to NAD83(CSRS)v7 Epoch 2010, while elevations use CGVD2013. This spreadsheet from the Government of Alberta is current to November 6, 2020.

Use Cases

• Establish precise geodetic control for construction projects based on published ASCM coordinates.
• Perform elevation analysis and modeling based on CGVD2013 referenced elevation data.
• Integrate survey control points into GIS systems based on NAD83(CSRS)v7 coordinates.
• Verify and update local survey networks based on the provincial readjustment data.

Strengths

• 32,971 published ASCMs provide a substantial network of control points.
• Coordinates are referenced to a specific, modern geodetic framework (NAD83(CSRS)v7 Epoch 2010).
• Elevation data uses a current vertical datum (CGVD2013).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is known, but specific data types and completeness of each record are unknown.
• Data is specific to Alberta, limiting applicability to other regions.
