Description:
Abstract: This spatial dataset contains the elevations of benchmarks established within the province of Allberta for the Ministry of Environment's Water Management Operations unit. A benchmark is a relatively permanent object, natural or artificial, whose geodetic elevation is known.It should be noted that other GoA ministries and departments may have additional elevation benchmark information and that this dataset should not be considered complete for the province of Alberta.
Purpose: Depict the elevation at locations in Alberta
Supplemental Information: The position of the points in this dataset do not correspond to the true location of the elevation benchmarks but represent the centre of the quarter section in which the benchmark resides. To locate a benchmark the user needs to access the benchmark report found in the Benchmark Retrieval Infromation System, available online at http://www.environment.alberta.ca/01533.html.

Data Quality Information:
Attribute Value Accuracy Information:
Quantitative Attribute Accuracy Assessment:
Attribute Accuracy Explanation: At the time the benchmarks were established the true elevation was known. Due to erosion and other factors affecting the on the ground location of the benchmark the true elevation maybe different than what is recorded in the data.
Positional Accuracy:
Horizontal Positional Accuracy:
Horizontal Positional Accuracy Report: Locations of benchmarks are calculated to the centre of the nearest quarter-section in meters as determined by the Alberta Township Survey. To determine a benchmark's exact field location use the description in its associated PDF file found on the Benchmark Retrieval System website (http://environment.alberta.ca/01533.html).
Quantitative Horizontal Positional Accuracy Assessment:
Horizontal Positional Accuracy Value: 600
Horizontal Positional Accuracy Explanation: Value based on the maximum distance in meters from the centre of a quarter-section to any corner.
Vertical Positional Accuracy:
Quantitative Vertical Positional Accuracy Assessment:
Vertical Positional Accuracy Explanation: At the time the benchmarks were established the true elevation was known. Due to erosion and other factors affecting the on the ground location of the benchmark the true elevation maybe different than what is recorded in the data.
