The City of Montreal experimented an automated process to generate a canopy digital model by image correlation. The model is especially used to measure urban heat island. An article presenting this project was published in the Quebec Professional Land-Surveyors Association’s journal. A 10 pts/m² LiDAR survey of the Montreal Island realized by XEOS Imaging in Fall 2015 was used to corroborate the results obtained through the image correlation.
