Cover Story: The Land Change Monitoring, Assessment, and Projection (LCMAP) project has released a suite of 10 annual land cover and land surface change datasets between 1985 and 2017 across the United States at a 30-m spatial resolution. This paper presents a method for automatically evaluating LCMAP results during the production phase based on 14 indices to quickly find and flag erroneous tiles (150 km × 150 km). The algorithm focused on using the local outlier factor analysis to find erroneous tiles through comparison with surrounding tiles. Our analysis showed that all local outlier scores for the published LCMAP tiles are below the outlier threshold. The overall agreement between LCMAP and the National Land Cover Database land cover products on a tile basis is above 71.5% and has an average of 89.1% across the 422 tiles in the conterminous United States.
