RSEI shapefiles define the grid and can be used for mapping. They do not contain any RSEI results. New shapefiles were posted on the RSEI ftp site in early 2017. The shapes are the same; however, the fields and format are different, and now additional files for grid cell sizes other than 810m are available. The attribute table is the same for all shapefiles. More information on the RSEI grid can be found in the RSEI methodology document.

Attribute Table for Grid Shapefiles

(Current version, e.g., poly_gc14_conus_810m_bottom.dbf)

Variable

Description

CELLX

Assigned grid cell value based on latitude.

CELLY

Assigned grid cell value based on longitude.

CLAT

Latitude for the center point of grid cell.

CLONG

Longitude for center point of grid cell.

CX

Vertical distance from the grid center point to grid cell (m). Equivalent to CELLX*grid size (m) (for standard RSEI grid, CELLX*810).

CY

Horizontal distance from the grid center point to grid cell (m). Equivalent to CELLY*grid size (m) (for standard RSEI grid, CELLY*810).

Attribute Table for Grid Shapefiles

(Older version, e.g. ConUS_810m_1)

Variable

Description

X

Y

Assigned grid cell value based on longitude.

LONGX

Easting coordinate for Albers projection.

LATY

Northing coordinate for Albers projection.

LONGITUDE

Longitude for center point of grid cell.

LATITUDE

Latitude for center point of grid cell.

RADIALDIST

Radial distance from center point of grid (m).

AREA

Area of grid (m) (note that grid cells vary slightly in size).

NORTHADJ

Internal.
