We just finished compiling the following video which shows a phenology (study of nature over time) on how the Medrona Marsh Preserve in Torrance, CA has changed during 2019.
These drone images show how the Madrona Marsh Preserve has changed from January 2019 to January 2020. As you will see, there is significant changes since 16.59 inches in total rainfall fell during the year. Focus on the left side (West) of the site to see the most significant changes in water levels — with the whole site’s vegetation changing colors throughout the seasons.
This was created by combining 12 months of orthomosaics into a time lapse video. Each month’s orthomosaic was created by combining (stitching) 400 low altitude drone photographs into precision map.
