Calculate the Spill Point of a surface in a 2-D grid

Description

Calculate the Spill Point of a surface in a 2-D grid

Usage

spill.point(dbgrid, name.depth = NA, dbdata = NA, name.cond = NA, 
hmax = NA, upwards = TRUE, cross = TRUE, unknown = TRUE, verbose = FALSE,
radix = "Spill.Point",modify.target = db.locmod())

Arguments

dbgrid

The db-class structure containing the 2-D Grid file

name.depth

Rank of the attribute containing the depth information. If not defined explicitely, the first "Z" field is used.

dbdata

The db-class structure containing the 2-D Data file. If this file is defined, the variable containing the data information is first migrated to the nodes of the Grid file. If not defined, it is assumed that the conditioning variable is already defined in the Grid file.

name.cond

Rank of the attribute containing the data information. If not defined explicitely, the second "Z" field is used.

hmax

Maximum reservoir thickness. If not defined, there is no limit on the reservoir thickness.

upwards

When TRUE, the grid variable is considered as elevation. Otherwise, the grid variable is considered as depth.

cross

When TRUE. the connectivity (in the 2-D grid) is defined as the four closest nodes (edge-connectivity). Otherwise, the connectivity is defined as the eight closest nodes (edge and corner connectivity).

unknown

When TRUE, the UNKNOWN pixels of the grid as converted into RESERVOIR.

verbose

1 for a verbose output; 0 otherwise

radix

Radix of the name given to the variables storing the results in the target Db.

modify.target

Decides whether or not the newly created variables will have their locator defined or not. For more information, see db.locmod.

Value

A db-class where the spill point variable has been added.
