imbedm

Encode data points into regular data grid

Syntax

Z = imbedm(lat, lon, value, Z, R)
Z = imbedm(lat, lon, value, Z, R, units)
[Z, indxPointOutsideGrid] = imbedm(...)

Description

Z = imbedm(lat, lon, value, Z, R) resets certain entries of a regular data grid, Z. Specify R as a GeographicCellsReference or GeographicPostingsReference object. The RasterSize property of R must be consistent with size(Z).

Z = imbedm(lat, lon, value, Z, R, units) specifies the units of the vectors lat and lon, where units is any valid angle units character vector ('degrees' by default).

[Z, indxPointOutsideGrid] = imbedm(...) returns the indices of lat and lon corresponding to points outside the grid in the variable indxPointOutsideGrid.

Examples

Create a simple grid map and embed new values in it:

Z = ones(3,6)

Z =
     1     1     1     1     1     1
     1     1     1     1     1     1
     1     1     1     1     1     1
refvec = [1/60 90 -180]

refvec =
    0.0167   90.0000 -180.0000

newgrid = imbedm([23 -23], [45 -45],[5 5],Z,refvec)

newgrid =
     1     1     1     1     1     1
     1     1     5     5     1     1
     1     1     1     1     1     1
