Map products accompanying report Watershed Description Water Quality Conceptual Water Budget Threats, Issues and Concerns
Map products accompanying report Watershed Description: Is an assessment of the watershed’s fundamental natural and human- made characteristics. It provides context for public consultations on water quality and quantity.
Map products accompanying report Water Quality: Provides a general assessment of surface and groundwater quality conditions and trends using data from existing sources. Objectives are to describe the current state of surface and groundwater quality and to identify long-term trends to see if water quality is improving, deteriorating or staying the same.
Map products accompanying report Conceptual Water Budget: Process that identifies how much water is available in the watershed and illustrates how water moves through the watershed. Includes human and environmental needs. Currently working on the conceptual water budget which provides an initial understanding of the watershed. Further analysis will be done in the future.
Map products accompanying report Threats, Issues and Concerns: Inventories of threats, issues and concerns for further investigation

Presentation Outline Help explain how science and technology is being used can look at GIS
What is GIS? Geographic Information System It is both the tool and the concept
GIS as a Tool Consists of: Integration of thematic digital data. Storage of information in common coordinate bases e.g.. UTM ZN 17 nad83 Implementation of a mapping/cartography system (the products) Database management system (RDBMS) Toolsets which allow data generalization/categorization, interpretation, interpolation, derivation, extrapolation Modeling capabilities for “what if” scenarios KEY: to link spatial data with attribute data on common coordinate system
What is GIS Science of Geomatics What is Geomatics The science and technology of gathering, analyzing, interpreting, distributing and using geographic information. Basis in: Mapping Cartography Photogrammetry/Remote sensing Surveying/GPS
We have a technology (the GIS) which is based on the merging of numerous scientific principles. To use scientific and technology in a GIS in SWP we need: 1. Good quality data 2. Highly skilled individuals 3. Highly knowledgeable individuals
Good quality data: •Federal - Statistics Canada •Provincial - Ministry of Natural Resources •Municipal - Official Plans •Non profit - Nature Conservancy •Community - Friends of the Bayfield •Internal - Field sampling •Private - MPAC
Caveats: Inaccuracies inherent in all data •Spatially inaccurate •Spatial generalization •Attribute generalization •Temporarily inaccurate •Created from inaccurate instruments •Human misinterpretation
We have a technology (the GIS) which is based on the merging on numerous scientific principles. To use scientific and technology in a GIS in SWP we need: 1. Good quality data 2. Highly skilled individuals 3. Highly knowledgeable individuals
Highly skilled individuals: Hydrologists and hydrological modelers. Groundwater Specialists Consulting companies with specialized skills. Source data itself is created from high level skill base.
Highly knowledgeable individuals: Peer review and stakeholder input Is information accurate Do assumptions make sense Does the analysis or the interpretations make sense Are the relationships between phenomena understood
So… Good quality data Skilled and knowledgeable individuals Scientific and technological fundamentals Technological environment in which to integrate it all. A few map examples...
SWP approached in a scientific and technological manner needs: Good quality data Skilled and knowledgeable individuals Scientific and technological fundamentals Technological environment in which to integrate it all.
