Collection - Emergency Geomatics Services (EGS) River Ice Archive

This data set contains the archive of river ice roughness as monitored on selected rivers by Natural Resources Canada (NRCan) using satellite imagery for the mitigation of ice jam associated risks. In order to mitigate ice jam induced floods risks and damage to infrastructure, Natural Resources Canada emergency geomatics service (EGS) may be activated by Canada's emergency management authorities. As new satellite imagery becomes available, NRCan will produce river ice roughness maps and update the dataset in near real time (4 hours). The river ice product is generated and validated on a best effort basis. Various factors may affect the quality of the river ice roughness maps. Those factors include but are not limited to sensor type, image resolution or the limitations of the methodology used.
