Portsmouth Catholic Regional

This is an open source research project built and maintained by a small team of volunteers. We aim to build the highest-quality dataset of churches in the USA, but occasionally we won't get every detail right. We welcome constructive feedback to help improve the quality of the dataset.

¹Place and building footprint calculated from Overture Maps Foundation. Checked against government outlines in 75 counties: two-thirds land within 5%, under 7% off by more than 2×.
