Pelias has a long list of features and improvements we wish to make. While we track most of them in GitHub issues, this document records high level priorities for the development of the project as a whole.
As an open-source project, we don't usually have a timeline or estimate for when items on our roadmap will be completed, but this document does serve as a roughly priority order of major changes we hope to make.
The Pelias autocomplete endpoint currently supports extremely limited typo correction. However, this support is really a result of implementation details, and not a result of a concerted effort.
By adding such a feature in a deliberate way we can greatly increase the usability of the autocomplete endpoint.
Pelias currently has a component called the PIP service for performing point in polygon calculations, but it's architecture and capabilities have become a huge limiting factor for Pelias.
Over the past year, we have been working on a more powerful and efficient replacement, the Spatial service.
The spatial service will allow advanced functionality such as custom administrative areas, using administrative data from OpenStreetMap, returning polygon data in Pelias responses, or adding postalcodes to more records based on a geometry.
Overall, Pelias has a solid foundation of language and internationalization support. The Pelias data schema allows for records to have multiple name values. These might include names in different languages, alternate names, colloquial names, or common abbreviations (for example airport codes).
However, not all data importers currently add multiple names, even when they are available in the source data. Furthermore, not all our queries use these alternate names effectively.
Pelias currently supports querying for administrative areas in many languages on
the /v1/search endpoint.
For autocomplete, the queries are not currently able to utilize multiple administrative area names.
Additionally, due to limitations in the polylines data format, no streets imported from OSM include alternate names, even if they are available in OSM.
