    • 6K Quads Map Service for ER Reference, US, EPA, SEGS

    Metadata Updated: March 22, 2024

    This dynamic web map service contains reference quads for emergency response reconnaissance developed for use by the US Environmental Protection Agency. Grid cells are based on densification of the USGS Quarterquad (1:12,000 scale or 12K) grids for the continental United States, Alaska, Hawaii and Puerto Rico and are roughly equivalent to 1:6000 scale (6K) quadrangles approximately 2 miles long on each side. Note: This data set is also available as a downloadable national-scale file (>80MB) and as individual regional subsets. Each regional extract includes a 20 mile buffer of tiles around each EPA Region.
