Data and Resources

Dataset Extent

Latitude: 48.0° to 60.0°
Longitude: -139.5° to -113.5°

Additional Information

Purpose

Quantify some aspects of hydrology and fish habitat, and to compare different regions of the province.

Lineage Statement

Planimetric positional data are line segments whose end points originate as points marked on streams on 1:50K NTS mapsheets. Following the geo-referencing of these end points to the BC Watershed Atlas 50K Stream centreline network and the application of the ESRI Dynamic Segmentation Model the two the end points for each line segment, with designated linear measures, are used to create a macro-reach (event arc) from an exact trace of the stream channel between the two end points. Full coverage of the province.
