Another file with a different cell size can be created from an existing grid file. Firstly, the program requests the original grid file. It then shows the following dialog box where New Cell Size and the File Type of the grid to be created are entered. It is also possible to select the coordinates of the resulting grid’s corners to obtain a smaller surface.
Cells
Current size: The size of each current cell in the grid to be resampled.
Number of current cells: The number of existing cells in the grid to be resampled.
New size: The new cell size for the resulting grid. The value of the size of the cell may be inserted manually or in the dropdown menu selecting the multiplying factor.
Number of new cells: The total number of cells for the new grid based on the new size established.
Coordinates: This option enables us not to convert the complete grid but just a part of the same, for which we need to graphically define the window which defines the part of the grid to be converted. The complete grid will be resampled by default.
Type of File: Enables us to create an ASCII or binary grid on creating the resulting grid.
In reality, if one has the surface file used to create a grid file in addition to the grid file, it is much more accurate to create another grid file with the cell size desired than to resample the grid. This option should solely be used if one only has the grid file.
