seismic.grid.define {RGeostats}R Documentation

Create Seismic converted Grid

Description

Create a Time Grid from a Depth Grid, or vice versa

Usage

seismic.grid.define(db, ivarv = 1, flag.z2t = 1, 
x0 = NA, dx = NA, nx = NA, verbose = 0)

Arguments

db

The input db-class structure containing the Depth information if flag.z2t=T. The input db-class structure containing the Time information if flag.z2t=F.

ivarv

The field index for the Velocity variable in the input db-class Db

flag.z2t

When TRUE, conversion from Depth to Time. When FALSE, conversion from Time to Depth

x0

Vector giving the origin of the resulting grid. If not defined or if the vector does not have the correct dimension (same space as the input Db), the values calculated from the input Db prevail

dx

Vector giving the mesh of the resulting grid. If not defined or if the vector does not have the correct dimension (same space as the input Db), the values calculated from the input Db prevail

nx

Vector giving the number of grid meshs of the resulting grid. If not defined or if the vector does not have the correct dimension (same space as the input Db), the values calculated from the input Db prevail

verbose

Verbose flag

Value

The resulting db-class structure, i.e. a Time Grid if flag.z2t=T or a Depth Grid if flag.z2t=F
