The system used by AES Flight Services captures high resolution, multi-spectral imagery that includes a near-infrared band particularly well suited for detecting chlorophyll. This allows geospatial and ecological professionals to detect tree species and diseases, vegetation changes, canopy cover and other important characteristics.
For urban tree canopy work, we integrate our imagery with existing urban street tree inventories, when available, and we employ targeted ground-truthing for quality assurance.
Our integrated expertise in ecology, geospatial mapping and data analysis, photo interpretation, and modeling allows us to determine the optimal image resolution (scale and pixel size) and plan the best times for image acquisition.
For the City of Ann Arbor, MI, we performed a “just-in-time” capture of peak autumn colors, maximizing image contrast for species classification. In Madison, WI, we collected high-resolution imagery to determine the extent of damage from the emerald ash borer. In the Chicago suburban area, we collected imagery to map the invasive species on forest preserve properties along the lower DuPage River.
Our ability to address issues of urban forest health allows us to formulate a matrix of ecosystem services and green infrastructure elements specific to your urban forest. From this, we can draft scientifically based recommendations for future management and restoration actions.
