Is your 3DEP coverage complete and current or does it resemble a checkerboard of new, dated, and missing areas? If the latter, join the NSGIC 3DEP for the Nation team for a step-by-step approach to identifying and addressing 3DEP coverage gaps. The first in the series, this workshop will focus on methods and tools that can be applied to identify coverage gaps and to assess the reasons that data has not yet been collected. Working collaboratively, states will categorize the reasons and, in follow-up workshops, develop strategies for addressing the 3DEP gaps and action plans for completing statewide coverage. The workshop series is intended to continue in alternate months and provide states an opportunity to share insights and approaches to closing the 3DEP gap.
