Landmarks for Maps

A landmark is a recognizable natural or artificial feature used for navigation and orientation. This repository collects Wikidata entities that are landmarks for cartographic use.

How to contribute

In sources create a new TSV file with the first column being the QID of the entity in Wikidata and an optional second column to make it easier to work with the data.

landmark_qid	debug_label
Q216344	Arlington National Cemetery
Q54109	United States Capitol

Before you reference a Wikidata entity ensure:

• It has a P625 coordinate location statement

Create GeoJSON from source data
