Understanding a topographic map is a non-trivial perceptual and cognitive process that is a critical part of Land Navigation training.  Here we describe progress with an accelerated training protocol using high-repetition simulation-based training to develop map reading skill prior to field exercises. This novel training approach, CERES, is based on procedurally-generated microsimulations that provide practice repetitions connecting a topographic map to a first-person terrain viewpoint.  Each simulation-based training event is completed in 30-60 seconds, allowing for large numbers of training microsimulations to be completed per hour of study. This high-repetition approach triggers the process of implicit learning, leading to the development of fluid, automatic, and expert cognitive performance.  The CERES training approach is accomplished using procedural generation of terrain environments, associated topographic maps and first-person perspective videos of movement through the terrain.  Participants indicate understanding of the map by reporting the orientation of video movement on the matching topographic map.  Feedback about the accuracy of this orientation judgment is provided and task difficulty is adjusted adaptively to guide learning. With practice, participants gradually improve their ability to connect the three-dimensional terrain video features of the simulated environment with the structure implied by the contour lines from the two-dimensional topographic map representations.  Understanding the relationship of map to environment is necessary for navigation and to make planning decisions appropriate to the environment. The CERES training approach is designed to supplement traditional classroom instruction and support initial steps toward expertise through simulation-based practice prior to experience in the field.
