Pecora 2022

Under the big data paradigm, many national mapping programs are feeling the pressure to increase frequency and reduce latency of national-scale map products. Conterminous United States (CONUS)-scale land cover programs are especially challenged given the efficiencies required to produce classified maps at this scale, let alone annual products using rulesets or imagery representing near current conditions. Data users have high expectations of accurate near-real time data that they can use to update their near-real time models and processes. But that’s the goal and the game is on! New satellite and aerial platforms, computing technologies, and models are helping to speed things up and increase accuracy, aided by cloud computing, state of the art compositing and change detection algorithms, artificial intelligence, machine learning, new sensors and space-aerial-ground lidar. In this special session, representatives from LANDFIRE, NLCD and LCMAP will showcase processes and technology that are being applied to get mapped products out the door faster and better.
