tall, you would use GRID_TYPE_PIXEL_SIZE="800,600".<br />
• GRID_TYPE_ROWS_COLS - specifies that the export should be gridded into multiple tiles with a<br />
given number of rows and columns of tiles. The value should be specified as number of rows,number<br />
of columns. For example, if you want to tile the export into a grid of 8 rows each 4 tiles across, you<br />
would use GRID_TYPE_ROWS_COLS="8,4".<br />
• GRID_OVERLAP - specifies how much to overlap tiles when gridding an export into multiple tiles.<br />
This is a percentage value from 0 to 100 and only applies when on of the GRID_TYPE_* parameters<br />
is used. For example, to make your grid tiles overlap by 5% of the grid tile size, use<br />
GRID_OVERLAP="5.0". The default value is 0.0, meaning that the tiles do not overlap.<br />
• GRID_KEEP_CELL_SIZE - specifies that the size of the grid cells should be maintained over sample<br />
spacing. This means that if you specify a grid of 4 rows and 5 columns, each grid cell will be exactly<br />
25% of the total export height and 20% of the total export width. The sample spacing may be slightly<br />
smaller than what is specified in order to achieve this. By default, the sample spacing is exactly<br />
maintained and each grid cell may be slightly larger than specified to maintain an integer number of<br />
exported cells. Use GRID_KEEP_CELL_SIZE=YES to enable.<br />
• GRID_NAMING - specifies how to name tiles when gridding an export into multiple tiles. The value<br />
should be SEQUENTIAL for sequential numeric naming starting at 1, SEPARATE for separate prefix<br />
appending by row and column, or SEPARATE_COLS_FIRST for separate prefix appending by<br />
columns and rows. For the SEPARATE options, use the GRID_NAMING_COLS and<br />
GRID_NAMING_ROWS parameters to specify the details of how to name the rows and columns. If<br />
no GRID_NAMING parameter is supplied, the last selected grid naming options selected in the user<br />
interface will be used.<br />
• GRID_NAMING_COLS - specifies how to name the column portion of grid cell names when using<br />
the GRID_NAMING=SEPARATE or GRID_NAMING=SEPARATE_COLS_FIRST parameter. The<br />
value of this field is a comma-delimited list with the following field values:<br />
♦ Naming type. Can have the following values:<br />
◊ NUM - name using numbers in ascending order<br />
◊ NUM_REVERSE - name using numbers in descending order<br />
◊ ALPHA - name using letters in ascending order<br />
◊ ALPHA_REVERSE - name using letters in descending order<br />
♦ Starting value for numbering or lettering (i.e. '1', or 'A').<br />
♦ Prefix string to use before the numeric or alphabetic value.<br />
♦ Step value for numeric naming (default is '1')<br />
You can leave values blank if they don't apply or you want to use the default. As an example, to do<br />
numeric naming starting at the number 100, increasing by 10 each time with a prefix of DEM, you<br />
would use GRID_NAMING_COLS="NUM,100,DEM,10".<br />
• GRID_NAMING_ROWS - specifies how to name the row portion of grid cell names when using the<br />
GRID_NAMING=SEPARATE parameter. See the documentation for the GRID_NAMING_COLS<br />
parameter above for details on the format.<br />
• GRID_NAMING_PREPEND_ZEROES - specifies whether or not to prepend zeroes to the start of<br />
grid column/row names. Use GRID_NAMING_PREPEND_ZEROES=NO to disable the prepending<br />
of zeroes.<br />
• GRID_NAMING_SEPARATOR - specifies the separator string to use between pieces of a grid name.<br />
The default is an underscore.<br />
• GRID_CREATE_FOLDERS - specifies that a separate folder should be generated for each row (or<br />
column if GRID_NAMING=SEPARATE_COLS_FIRST is specified) of the export rather than<br />
placing every output file in the same folder.<br />
• QUALITY (JPEG or GEOTIFF only) - specifies the quality setting to use when generating the image.<br />
Valid values range from 1 to 100, with 1 generating the lowest quality image and 100 generating the<br />
highest quality image. If no QUALITY setting is present, a default value of 75 is used which<br />
generates a very high quality image that is still highly compressed. Note that if a different quality<br />
