The data used here are field collected photo points with attributes for photo ID and photo bearing in the […]

It’s hard to connect the two conceptually because the settings directly correspond but are about a dozen mouse-clicks apart in the UI. I’m on ArcMap 10.1, using maplex in this demo. To add a leader […]
