Olmsted Online can be used to plan an outing, explore history, research designs, analyze changes in land use and support the preservation, restoration and maintenance of the historic Olmsted-designed landscapes.

Who can use Olmsted Online?

Environmental resource and transportation planners, landscape architects, historians, educators, preservation and park advocates, visitors bureaus, gardeners, local residents and tourists can all benefit from Olmsted Online.

Who created Olmsted Online?

The National Association for Olmsted Parks developed Olmsted Online in 2013 with the participation of representatives from Friends of Seattle's Olmsted Parks, the Frederick Law Olmsted National Historic Site, National Park Service and a dedicated group of volunteers. NAOP received a federal Transportation Enhancement grant administered by the Washington State Department of Transportation to digitize and locate on a base map original materials from the Olmsted firm's work in the Puget Sound and Washington State.

Help us grow Olmsted Online to accommodate all Olmsted projects in North America and internationally.

Would you like to see the information for the Olmsted-designed landscapes in your location?

NAOP invites you to partner with us. By digitizing historic materials for your location's Olmsted work and combining them with other historical data and descriptive material, you will have access to plans, maps, historic photos and correspondence that directly support advocacy, research and cultural tourism efforts—and a deeper appreciation for the Olmsted legacy. Integration of the materials with our national mapping site will also bring the attention of a nationwide audience to your unique Olmsted resources.
