Learn how to integrate disparate GIS datasets by transferring height values based on spatial proximity and overlap. This tutorial covers the "Copy Attributes Between Overlapping/Nearby Features" function in Global Mapper. We demonstrate a practical workflow for supplementing National Map building footprints with accurate height data from GIS Integrated Building Data, even when geometries do not perfectly align. In this tutorial, we will learn how to transfer attributes between nearby or overlapping features in Global Mapper. Instead of processing queries by referring to attribute tables, this method determines whether objects are close enough or overlapping to transfer the desired attributes. Why Spatial Attribute Transfer Matters Why We Need This: Integrating Building Height Data For landscape simulations, it is essential to know the height of buildings. However, the standard "Continuous Digital Map...
