SAGA.grid_tools.23: Create Grid System

This tool creates a new user specified Grid System for use with other tools.<br/><br/>First of all, please consider the following issues before using the tool:<br/>(a) all calculations of the tool refer to the lower left corner of the grid system, i.e. the xMin and yMin values. This coordinate is fixed unless you specify an offset.<br/>(b) the tool follows the philosophy of SAGA in that the values describing the extent refer to the cell centers. If you like to match the extent with the border of a grid, use an offset.<br/><br/>The tool provides four possibilities to set/determine the extent of the grid system:<br/>(1) by specifying the coordinate of the lower left cell (xMin, yMin) and the number of cells in W-E (NX) and S-N (NY) direction<br/>(2) by specifying the coordinates the of lower left (xMin, yMin) and the upper right (xMax, yMax) cell<br/>(3) by the extent of the shape(s) provided in the Data Objects section<br/>(4) by the extent of the grid(s) provided in the Data Objects section<br/><br/>After selecting the appropriate method to determine the extent, the next step is to specify the Cellsize of the new grid system.<br/>For all methods supplied to determine the extent but number (1), three possibilities are provided to adjust Cellsize and grid system extent (please remember, the lower left corner is fixed!):<br/>(I) adjust the extent to match the Cellsize<br/>(II) adjust the Cellsize to match the extent in E-W direction<br/>(III) adjust the Cellsize to match the extent in S-N direction<br/><br/>Finally it is possible to apply an offset to the lower left corner of the grid system. In this case check the Use Offset option and specify the offset in W-E and S-N direction. Positive values result in a shift in E/N, negative in W/S direction.<br/>In order to create the grid system the tool needs to create a dummy grid.
