Metro Vancouver delivers core utility services such as drinking water and wastewater treatment to localx000D
governments as well as planning for growth and regional parks. The diversity of land cover types and scales inx000D
the urban mosaic results in relatively high rates of mapping errors among urban and other land cover classes,x000D
which can be a problem for urban planning. Our original ENGAGE project involved a detailed investigation ofx000D
advanced remote sensing technologies, specifically high spatial resolution RAPIDEYE as well as Lightx000D
Detection and Ranging (LIDAR) to map urban land cover at extremely high spatial resolution (<5m), at a levelx000D
never before available to MetroVancouver. Building on this, we wish to extend the research via ENGAGE Plusx000D
to investigates the use of RapidEye and LiDAR for monitoring aquatic systems in urban areas. Land use andx000D
land cover (LULC) changes in urban areas have fundamental impacts on stormwater runoff, contaminant flow,x000D
and urban stream health. Increasing impervious (paved) surfaces can result in "flashier" runoff and contributex000D
sediments and contaminants to aquatic systems. Landscape elements such as riparian vegetation can mitigatex000D
flooding and filter runoff, yet when converted to impervious surfaces, can exacerbate such problems. Here, wex000D
will build on the urban land cover we produced to create approaches for monitoring urban streams usingx000D
landscape indicators. We use the high spatial resolution imagery from our first ENGAGE to fill urban aquaticx000D
monitoring needs in Vancouver. These techniques will provide transferable tools for other Canadian cities forx000D
monitoring ecological health.
