| /** |
| * Simple data store implementations for some ESRI grid formats (ASCII and binary). |
| * The data formats supported by this package are relatively simple. |
| * Values are stored either in plain ASCII text or in RAW binary encoding (without compression). |
| * |
| * <h2>Extensions</h2> |
| * The implementation in this package adds the following extensions |
| * (some of them are taken from GDAL): |
| * |
| * <ul class="verbose"> |
| * <li>Coordinate reference system specified by auxiliary {@code *.prj} file. |
| * If the format is WKT 1, the GDAL variant is used (that variant differs from |
| * the OGC 01-009 standard in their interpretation of units of measurement).</li> |
| * <li>ASCII Grid reader accepts also some metadata defined for the binary formats |
| * ({@code XDIM}, {@code YDIM}, color file, statistics file, <i>etc.</i>).</li> |
| * </ul> |
| * |
| * <h2>Limitations</h2> |
| * Statistics file ({@code *.stx}) contains {@code band}, {@code minimum}, {@code maximum}, {@code mean}, |
| * {@code std_deviation}, {@code linear_stretch_min} and {@code linear_stretch_max} values. |
| * But in current Apache SIS implementation, the last two values ({@code linear_stretch_*}) are ignored. |
| * |
| * <p>Color map file ({@code *.clr}) is read only when the raster does not have 3 or 4 bands |
| * (in which case the raster is considered RGB) and when the data type is byte or unsigned short. |
| * In all other cases, notably in the case of floating point values, the color map is ignored.</p> |
| * |
| * <p>Current implementation of ASCII Grid store loads, caches and returns the full image |
| * no matter the subregion or subsampling specified to the {@code read(…)} method. |
| * Sub-setting parameters are ignored.</p> |
