This Website provides an interface for PA Breeding Bird Atlas staff and volunteers to find survey blocks, enter their findings and view results. I developed the component with which users can view a map of a block and print a high-quality PDF map. To print a map, enter the site and click the "Register" link on the left side of the window. Then click the "View Regions & Blocks" link, select a block, click its "Block Map" tab and choose whether to print an air photo or a topo map.
