What is Pelias and why do you want a local one? Pelias is an open source tool that allows you to look up locations by name and turn them into geographically located data. In my line of work, I frequently use tools like this to geocode addresses, that is, turn addresses into lat/long coordinates. My teams typically need the coordinates for addresses so we can put them together with other datasets like demographics, socioeconomic measures, or environmental data to find out what the people in our households of interest are experiencing.
