| - | ^ Name ^ Type ^ Description ^ Default Value ^ | + | ^ Name ^ Type ^ Description ^ Default Value ^ |
| - | | 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 | |
| - | | 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 | | + | | Workdir | [[Workdir Type|Workdir]] | Workdir folder path. | 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). | + | |
| - | + | ||
| - | 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. | + | |

| - | All Geotiff coordinate systems are supported if translation is not needed. | + | |

| - | When GeoTiff cell dimension is not found, a 100 meter resolution is assumed. | + | |
