This data is 6-inch color orthophotography flown the week of February 15th, 2010 to document the impact of debris flows February 6th, 2010.
On the morning of February 6th, 2010, the community of La Canada Flintridge saw a major debris flow on a number of streets on its northern edge. This area had been on the southern edge of the Station fire in autumn 2009, and a heavy rainfall overnight caused a debris basin to overflow and neighboring houses to be impacted.
The County of Los Angeles through the Los Angeles Regional Aquisition Consortium (LAR-IAC), authorized the overflight of the southern boundary of the Station Fire in order to refresh existing imagery which would help the County and cities assess the impacts of the debris flow as well as analyze changes due to the station fire.
The capture was done by Aerial Express using a large-format camera and the County’s Elevation Model, which provides very good accuracy. Note that the specifications were off the shelf, and some building lean and shifting may be apparent, as it does not meet the near-engineering grade accuracy of the LAR-IAC2 4-inch imagery captured in 2008.
