The Global Paleomagnetic Database (GPD) from the National Geophysical Data Center (NGDC) contains many paleomagnetic sampling records from localities across the United States. These data are used to construct paleomagnetic poles for rock formations of different ages, which together can map out the Apparent Polar Wander Path for the North American craton. This study develops a method of consistency for the integration of these data with other sources of digital data, specifically The National Map (TNM) data layers of the U.S. Geological Survey and a set of archived geologic maps that have been previously conflated with each other and integrated with TNM. This method uses the geospatial precision given in the GPD to define a consistency criterion (goodness of fit) for this integration. The test area for this analysis is Ste. Genevieve County, Missouri.
