Data File Types 317
B.3.3 2-D EPRI
The 2-D EPRI file (2DEPR) is the same as the standard 2-D grid file type except for a
minor change in the way alpha characters increment:
• Standard 2-D grid file: Refers to the standard incrementing columns that start at
A and extend past Z. (Example: Start Column: A; End Column: AD; Column
Result: A, B, C...X, Y, Z, AA, AB, AC, AD.)
• EPRI 2-D grid file: Refers to custom incrementing columns that start at A and
extend past Z. (Example: Start Column: A; End Column: CC; Column Result: A, B,
C...Z, AA, BB, CC.)
B.3.4 2-D Matrix Grid with Custom Point
A 2-D matrix grid with custom points (2D + CPT) file is the same as a standard 2-D
grid file with the addition of custom points. Custom points allow multiple readings
per grid ID number to be assigned (see Table 29 on page 317).
Table 29 Example of 2-D matrix grid with custom point
Start Column A
End Column J (Start Grid Coordinate = A01)
Start Row 01
End Row 17 (End Grid Coordinate = J17)
Custom Points = LEFT
CENTER
RIGHT
Resulting file would contain the following
list of ID Numbers:
A01LEFT
A01CENTER
A01RIGHT
A02LEFT
