This project is parallel research to the GFC canopy assessment by
Owen Smith for Dr. Cho's GISC 4903 - Special Topics in GIS .
Its focus is on creating an open source canopy classification system designed
specifically to utilize NAIP imagery

A flow path $\FP_i$ is the watercourse between a pair of two points $i$ within the watershed and the longest flow path $\LFP$ is defined as
\[
\LFP\in\left\{\FP_i\;:\;\left|\FP_i\right|\geq\left|\FP_j\right|\;\forall i\neq j\right\}.
