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 available as a national-scale file (>80MB) and as individual regional subsets. Each regional extract includes a 20 mile buffer of tiles around each EPA Region. The URLs for each are as follows: Entire Country: https://edg.epa.gov/data/Public/OLEM/OLEM-OEM/6kquads_epa.zip, Regional subsets: https://edg.epa.gov/data/Public/OLEM/OLEM-OEM/6kquadr[enter region number].zip (e.g., R6 subset URL https://edg.epa.gov/data/Public/OLEM/OLEM-OEM/6kquadr6.zip) To provide a base reference grid system for the entire United States as a pre-staged resource for tracking and planning emergency response activities such as reconnaisance of debris after natural disasters, oil spill cleanups and planning of monitoring activities. completed Josh Krochmal U.S. Environmental Protection Agency, Office of Land and Emergency Management - Office of Emergency Management EDG Steward 202.564.8753 1200 Pennsylvania Avenue, N.W.

During an EPA response, 6K quad layer should be related to a look-up table (see example table in MS Access file included in the download file) tblMASTER_STATE_GRID_LU_4SDE100406) to update and map response status efforts. The Lookup table to be used in ArcSDE to relate many 6k quad grid cells to different geographies (State and County). 24k grids for Alaska and non-CONUS areas also included because their shapes boundaries do not exactly match with child 6k cells. Data elements of the lookup table: REC_NUM Number unique id - comes from unique record number created in parent grid layers. Initially named as 6k_ref, then Ref_6k Ref_ID Text Created by concatenating [STATE]-[Rec_Num]. Initially was named as Ref_6ks STATE Text State Name - there can be multiple records with same rec_num but different state name STATUS Text Current Grid Cell Status field. Default value is 'NA'. Other possible values are 'Open', 'Closed' and 'Active' LOCKSTATUS Text Indicates a locked value for record. Possible valuesare 'NA'(default), 'Open', 'Closed' and 'Active' LOCK_CMNT Text When LocakStatus field value is not NA then, a comment in this field indicates who implemented lockstatus, and why. QQQUAD_REF Number Value from Rec_num field of '24ksubquadbound.shp' or orginal SubQuad layer which was created only for gulf coast hurricane prone areas. QQQUADREFT Text Ref_ID value from '24ksubquadbound.shp' CONUS Yes/No identifies grid cells which will be part of final 6k quad layer but Continental US areas only SEL_12K Yes/No Identifies all cells that intersect with 12k layer.

This lineage was generated by the FGDC CSDGM to 19139 transformation quads6k_us.shp layer is extracted from a base layer 'vectorgrid.shp'. Vectorgrid layer extents are as follows: MinX: -179 MaxX: -64 MinY: 17 MaxY: 72 These extents cover all CONUS, Alaska, Hawaii, and Puerto Rico. Total number of records in vectorgrid.shp is approx. 6.5 million. Grid Cell Height - .03125 degrees Grid Cell width - .03125 degrees quads6k_us.shp: This layer is slightly different from 12k or 24k quad layers. It is created strictly as 1/4th scale of a 24k quad grid, which is 1/4th of 7.5 Degrees X 7.5 Degrees i.e. 0.03125 degrees X 0.03125 degrees. Actual Quad map differ from strictly square grid shape, in some areas outside of CONUS. Field Definitions for 6k Quad Layer: Label (Text) - Label value (Unique). Sel_12k (T/F): Identifies all cells that intersect with 12k layer.
