Geospatial Web Applications
• Northern Data Discovery Portal• Regional Environmental Assessment
Toolkit - BREA• Emergency Response Application
Northern Data Discovery GeoPortal
• Web based access to wide variety data of interest to scientists, policy analysts and decision makers
– Non-GIS practitioners can use portal• Data from many departments with goal of each
group/department housing and maintaining their own data
• Portal provides interface to display, explore, analyze different datasets
Putting PLACE first
• Geospatial information platform - link to place-based coordinates
– Web based application
allows various information
layers from different
organizations to be
visualized and analyzed
without managing the
data

The Beaufort Sea – Wildlife and Monitoring
Protected Areas and EC Monitoring
Important Wildlife Areas (EC, DFO, Territories)
Traditional Knowledge/Use
The Beaufort Sea – Kendall Island MBSShoreline sensitivity to oil spills (eSPACE)
Regional Environmental Assessment Toolkit BREA
• Intended to aid government, industry, Aboriginal groups, resource managers and public stakeholders in better understanding the geographic distribution of areas which are sensitive for environmental and socio-economic reasons in the face of economic development
• Explore and visualize data
• Share and distribute data– Upload / download (with restrictions/control)
• Visualize and analyze interactions between biological or socio-economic variables with economic development– Where are potential conflict areas?– Cumulative effects scenarios
Advanced Functionality
• 2 Separate Tools Under “Cumulative Effects Scenario” menu
1. Analyze existing sensitivity layers (AANDC-PEMT) using the weighted overlay tool
2. Take vector sensitivity data either in portal or uploaded (i.e. Important bird areas) and generate VEC Sensitivity raster that can be incorporated
– Output new raster, named, stored
• Raster Calculator (simplified)– Combine rasters (with weightings) to create new outputs
Emergency Response Application
Mixed sediment beach with woody debris, upper intertidal zone, Yukon

Summary
• Organizations make web services available – maximize use of existing data hubs
• Data stored, managed, updated by responsible organization – can be ingested, displayed, analyzed by others
• Requires coordination, adherence to standards, interoperability
• Arctic Ocean Observing System (AOOS) working example
