Ontario Integrated Hydrology Data Package

Coordinate system: 3161 - "NAD83 / Ontario MNR Lambert"


Revision Note: Please note that this dataset has been revised and is available from the Land Information Ontario (LIO) Warehouse.

The Ontario Integrated Hydrology Data Package is a collection of related elevation and mapped water features that are used in combination for generating watersheds and to support hydrology applications. The integrated hydrology data is complete for the entire province making it possible to create a watershed for any location in Ontario. There are four key datasets represented by this collection:

1) a stream network (Enhanced Watercourse)

2) a hydrology-enforced DEM (Stream Enforced DEM)

3) a flow direction grid (Enhanced Flow Direction - EFDIR)

4) a raster representation of the stream network (StreamGrid)

There are also some useful reference datasets included to provide some context and information about these data sets.
