The online and printed Ag Trail map will locate many of the county's 1,700 dairies, farms, ranches, wineries, farmers markets, historical and cultural points of interest and UC Riverside agricultural research facilities.
"The idea is to promote agriculture, to promote the purchase of our products," said Tom Freeman, spokesman for the county Economic Development Agency. "We would target international visitors, domestic guests and our own residents."
Officials are aiming to complete the map by February 2013.
