spill.point {RGeoS} | R Documentation |
Calculate the Spill Point of a surface in a 2-D grid
spill.point(dbgrid, name.depth = NA, dbdata = NA, name.cond = NA, hmax = NA, upwards = TRUE, cross = TRUE, unknown = TRUE, verbose = FALSE)
dbgrid |
The |
name.depth |
Rank of the attribute containing the depth information. If not defined explicitely, the first "Z" field is used. |
dbdata |
The |
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 |
A db-class
where the spill point variable has been added.
