Hyperspectral imagery of Pinus strobiformis infected with fungal pathogen

Marja Haagsma, Gerald F. M. Page & Jeremy S. Johnson
Hyperspectral images were taken from March till October, 2018, of southwestern white pine (Pinus strobiformis), SWWP, seedlings of ten different seed-source families. Half of the seedlings were inoculated with white pine blister rust (Cronartium ribicola). Visual assessments of vigor coincided with hyperspectral data acquisition. The aim of the experiment was to use hyperspectral data to automaticaly and objectively identify infection and degree of infection in SWWP seedlings. Moreover, we developed and evaluated a feature importance...

Impacts of Intersection Treatments and Traffic Characteristics on Bicyclist Safety

David Hurwitz & Brendan Russo
This data provides observations and measurements used to answer questions of interest regarding how intersection and traffic characteristics impact the frequency and severity of bicycle-vehicle conflicts as part of the study titled “SPR 833 Intersection Treatments and Bicyclist Safety.” Data includes measurements from the field portion of the study used to assess post-encroachment time, hourly road user volumes, and conflict-involved road user speeds that were extracted from field-collected videos in Portland, Oregon.
