RSEI shapefiles define the grid and can be used for mapping. They do not contain any RSEI results. There are two sets: polygon (con_us_810m_poly) and center point (con_us_810m). The grid is split into 4 files for each type, numbered 1-4. The attribute table is the same for all shapefiles. More information on the RSEI grid can be found in the RSEI methodology document.
