Not long after Craigslist cut off a mapping app that tapped its housing data, the popular online bulletin board has quietly begun embedding maps in certain real estate listings.
The maps, which appear on housing ads in the San Francisco Bay Area and Portland, Ore., harness data from OpenStreetMap, a service that offers free maps of the world compiled and edited by volunteers.
The new feature emerges a little more than a month after Craigslist sued PadMapper, an apartment listings aggregator that collects listings from Craigslist and other services and displays them on a Google map. Craigslist, which has become a popular portal for apartment ads, sued PadMapper and the data harvester it uses -- 3taps -- on copyright infringement grounds.
For a short while PadMapper took Craigslist data off its site. But in July, PadMapper said it would resume using the data after it discovered a workaround that creator Eric DeMenthon described as "somewhat dickish" but "legally kosher."
Craigslist responded with a lawsuit filed in San Francisco's federal court, accusing the two companies of "unlawfully and unabashedly mass-harvesting and redistributing postings entrusted by Craigslist users to their local Craigslist sites."
CNET has contacted Craigslist for comment and will update this report when we learn more.
