| 4< | CentMer | 0.0 | Longitude of the central meridian |
| 5 | 0.0 | not used | |
| 6< | FE | 0.0 | False Easting in the same units as the sphere radius |

MODLAND Intergerized Sinusoidal (ISIN) Grid
| Num | Parameter | Value | Description |
| 0 | Sphere | 6371007.181 | Radius of reference (meters) sphere |
| 1-3 | 0.0 | not used | |
| 4 | CentMer | 0.0 | Longitude of the central meridian |
| 5 | 0.0 | not used | |
| 6 | FE | 0.0 | False Easting in the same units as the sphere radius |
| 7 | FN | 0.0 | False Northing in the same units as the sphere radius |
| 8 | NZone | 86400.0 | Number of equally spaced latitudinal zones (rows). Must be 2 or larger and even. |
| 9 | 0.0 | not used | |
| 10 | RFlag | 1.0 | Right justify columns flag is used to indicate what to do with zones with an odd number of columns. If it has a value of 0 or 1 it indicates the extra column is on the right (zero) or left (one) of the projection y-axis. If the flag is set to 2 the number of columns are calculated so there are always an even number of column in each zone. |

MODLAND TileGrid ID
The MODLAND TileGrid ID is an 8 digit integer, such as 51018009, that is used to specify a gridded product's projection,
tile size and horizontal and vertical tile number.
The first digit (the leftmost digit) is used to identify the
projection, i.e., the tiling scheme. The 3 possible values are:
3 - Lambert Azimuthal Equal-Area projection with projection center at the North Pole
4 - Lambert Azimuthal Equal-Area projection with projection center at the South Pole
5 - Sinusoidal projection
The second digit is used to specify the tile size. Only one possible value is used:
1 - full size tile
The next 3 digits (digits 3 to 5) are used to specify horizontal tile number, and the last 3 digit (digits 6 to 8)
is for the vertical tile number. The ranges of horizontal and vertical tile number is depending on the projection and
the tile size, they are listed in the table below.
| Projection | Size | Horizontal Tile Range | Vertical Tile Range |
| 5 | 1 | 0 to 35 | 0 to 17 |
| 3 & 4 | 1 | 0 to 8 | 0 to 8 |
Example: TileGrid ID 51018009 identifies a full size tile in the Sinusoidal projection with horizontal tile number 18 and vertical tile number 9.
