Historic Sites: USA 对比 Worldmarks 的使用情况和统计数据

Locate every site on the United States Historic Register! The United States National Historic Register contains over 85,000 entries, each a site that has been designated as having historic value. That means that no matter where you travel in the country you are almost certainly near one or more sites on the Historic Register. Finding those sites can be difficult! Most are not marked with any kind of signage, and there is no map showing of them. Historic Register Site Finder solves that problem! Historic Register Site Finder presents the standard Apple Map, with sites in the National Historic Register marked on the map at their location. For any locale you choose or for the area around your current location, you can see what Historic sites are nearby. You can use it in two ways: "Search and Locate" mode: Search for Historic sites by state, by city or by name, or any combination of those three. You'll get a list of all the sites matching your search criteria. From that list you can see more information about a site, or you can tap a site and the map will center itself on the site you selected. "While You're Moving" mode: As you drive or walk, the map will show your current location and any Historic Sites in the area. You can zoom the map to cover a small area or larger areas around your current position. In both modes you can see where sites are located on the map, and then see more detailed information about the site by tapping the site's callout balloon. With your Historic Register Site Finder, you'll be able to locate sites on the United States Historic Register and find them as you travel across the country. Cool, eh?
