Specifications Lake Drone Mapping Platform

1.0 Background

The Oklahoma and Central Plains Agricultural Research Center (OCPARC) requires fully automated lake volume survey drone for early warning flood alerts. This equipment is valuable in quantifying lake volume that will be used to generate early warning flood alerts from artificial intelligence algorithms. This data will assist farmers, ranchers, and producers to protect their croplands, livestock, and infrastructure (e.g., utilities; transportation routes for transporting crops from the field to processing plants, supermarkets, restaurants; commercial and residential properties).
