Geospatial Scientist

As a geospatial scientist with CCMEO my research involves geomatics and earth observation data.  My research interests include: the development of methods and implementation techniques to promote the interoperability and accessibility of water and flood mapping datasets, standards for water and disaster management datasets, and open-source, web-based tools to increase awareness of flooding and for communication of flood risk.

Natural Resources Canada

Current research and/or projects

Working with the team at CCMEO, we are continuing work on the Flood Mapping Guideline Series to complete the series and provide subsequent/revised versions as needed. 

Research into methods to leverage existing flood maps to improve awareness of flood risk through web services and/or web-based applications.

Looking into OGC Standards and water datasets to support improved accessibility and interoperability of geospatial data.

Research and/or project statements

Extending use and capabilities of HAND model by: relating height to discharge and the spatial extent which can be modelled by a given HAND model​, adding urban features (e.g. inclusion of culverts), weighted inputs, suitability map to increase flood awareness

OGC Standards and water datasets to support improved accessibility and interoperability of geospatial data

Design and development of Flood Mapping Metadata portal 

Development of new methods and easy to use tools to visualize the negative consequences from flooding, by leveraging open data resources
