| - | | Load As Sparse | [[ Bool Type|Bool ]] | If true, the map is loaded as a sparse image. Sparse images have the advantage of storing only the cells containing non-null values, but they have diminshed access time. | False | | + | | Null Value | [[Null Value Type|Null Value]] | Additional value used to represent null cells. Cells with such value are also treated as null cells. This is particularly useful for assigning a null value to image files that do not have this definition. | None | |
| - | | Define Null Value | [[Bool Type|Bool ]] | This flag forces the cells with the same value of the "Null Value" parameter to be treated as a null cell. This is particularly useful for assigning a missing null value to a GeoTiff data. | False | | + | | Load As Sparse | [[Bool Type|Bool]] | If true, the map is loaded as a sparse image. Sparse images have the advantage of storing only the cells containing non-null values, but they have worse access time. | False | |
| - | | Null Value | [[Int Type|Int ]] | Value used to represent null cell. The "Define Null Value" flag must be set in order to define a null value. This is particularly useful for assigning a missing null value to a GeoTiff data. | 0 | | + | | Suffix Digits | [[Non Negative Int Type|Non Negative Int]] | Number of digits used to represent the image file name suffix. | 0 | |
| - | | Suffix Digits | [[Non Negative Int Type|Non Negative Int ]] | Number of digits used to represent the image file name suffix. | 2 | | + | | Step | [[Non Negative Int Type|Non Negative Int]] | Current step or model iteration. Files with the same name and numbered suffixes will be loaded sequentially according to the model step. | None | |

| - | Readable formats: ers (ERMapper raster) tiff, or tif (GeoTiff) and asc (ArcView ASCII). | + | See also [[Load Map]] for loading maps whose cells do not represent categories. |
| - | Coordinate systems supported for translation in ERMapper format: Geodetic (WGS 84, SAD69, NAD27, Corrego Alegre) and UTM (WGS84, SAD 69, NAD27, Corrego Alegre). | + | If the "Null Value" parameter is specified, any cell corresponding to the original null value of the map, if provided, is converted to the new null value. This ensures that values originally represented by null value still representing null values, even if the null value definition changes. Any non-null value corresponding to the newly defined null value is also promoted to new null value. |

| - | When a coordinate system is not supported, LOCAL projection and datum WGS84 are assumed. For ASCII/ArcGIS, LOCAL projection and datum WGS84 are always assumed. | + | |
