Recently discovered an issue in exporting .pdf maps and wondered if anyone has seen this before or has a possible solution. Field crew reported a shift between two maps with the same data on them that were produced by myself and a contractor. The relative locations are all the same (maps look identical) but when using avenza the contractors map is approximately 12m off. I tried exporting a pdf using the contractors .mxd and it comes out correct. I believe the contractor is using ArcMap 10.3 and we are using 10.6.1. Could this be an issue? Any thoughts on settings we can check?
