The Regional Land Information System (RLIS) is a GIS dataset from Oregon Metro, the elected regional government for the Portland metropolitan area. RLIS delivers more than 100 GIS map layers for the region.
Oregon Metro exposes the RLIS data through a RESTful API intended for regional developers in need of geocoding functionality or data describing a given address. The API has two modes: locate and query. Accepted input types include addresses, intersections, POIs, taxlot IDs, zipcodes, and coordinates. The API returns JSON or XML formatted responses.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
