My friend Darvel Lloyd recently forwarded me a link to this fantastic new interactive map of the Portland metropolitan area’s urban canopy. Individual trees have been mapped and plotted from 2014 LiDAR data for the whole of the Portland area. This is the single most important contribution to tree height research ever made publicly available to the Portland area, and greatly exceeds in accuracy and ease of use earlier methods I had utilized using Google Earth’s 3D function starting 3 years ago in my attempt to locate Portland’s tallest trees. The new LiDAR tree heights are often a couple of feet taller than Google earth derived heights, but generally agree within 2%, plus or minus.
Credit is to be given to the fine researchers at Portland State University. Sustaining Urban Places Research (SUPR) Lab in the College of Urban and Public Affairs at Portland State University.
And a special thanks to Jackson Voelkel, Geospatial Research Analyst at the SUPR Lab, for stunning work on integrating LiDAR data for multiple complex GIS applications.
This interactive map makes big tree research a lot more fun, and more importantly adds immensely to the study of individual trees in the grand scheme of the environment & climate change research, as well as what role trees play in mitigating urban heat islands etc.
