+<b>DATA IDENTFICATION </b><br/>
+Abstract: The NAIP National Metadata Map contains USGS Quarter Quad and NAIP Seamline boundaries for every year NAIP imagery has been collected. Clicking on the map also makes available a number of metadata fields which describe the day, time, camera, aircraft, and location of NAIP collection. There is also a link which will open an FGDC compliant metadata text file for each NAIP USGS Quarter Quad collected.
+<br/>
+Purpose: To make additional information and metadata about NAIP available to the public.
