| <h1>Landsat to ISO 19115 metadata</h1> |
| <p> |
| Landset metadata are provided as <var>key</var>-<var>value</var> pairs in text files (ASCII). |
| While Landsat files are divided in groups (<code>METADATA_FILE_INFO</code>, <code>PRODUCT_METADATA</code>, |
| <code>IMAGE_ATTRIBUTES</code>, <code>MIN_MAX_RADIANCE</code>, <code>MIN_MAX_REFLECTANCE</code>, |
| <code>MIN_MAX_PIXEL_VALUE</code>, <code>RADIOMETRIC_RESCALING</code>, <code>TIRS_THERMAL_CONSTANTS</code>, |
| <code>PROJECTION_PARAMETERS</code>), they can nevertheless be though as flat structures since there is no |
| duplicated key names. Consequently the Landsat group are omitted in the following discussion. |
| But ISO 19115 metadata on the other hand are structured as trees, and this tree structure can not be ignored. |
| </p> |
| <p> |
| Landsat values are mapped to ISO 19115 metadata when an ISO property can be found for a Landsat key. |
| The Landsat to ISO mapping is not always a one-to-one relationship. |
| In some cases the ISO value need to be computed from two or more Landsat values. |
| In other cases the ISO value does not appear in the Landsat file at all, |
| so the value is hard-coded in the <code>LandsatReader</code> class. |
| </p> |
| <p> |
| In the following table, black values in the "Landsat property" column are hard-coded values. |
| Some of them are inferred from table 2-1: <cite>Band Reference Table</cite> in the Landsat Data Format Control Book (DFCB). |
| Green values are values to be read and interpreted as described in table 3-4: <cite>L1Gt / L1T Metadata File</cite>. |
| Values in the ISO 19115 column shown the paths to an ISO property relative to the <code>Metadata</code> root. |
| When an ISO property can accept various subtypes, the type used are those listed below: |
| </p> |
| <ul> |
| <li><code>identificationInfo</code> is of type <code>DataIdentification</code> (a <code>Identification</code> subtype)</li> |
| <li><code>contentInfo</code> is of type <code>ImageDescription</code> (a <code>ContentInformation</code> subtype)</li> |
| <li><code>attribute</code> is of type <code>Band</code> (a <code>RangeDimension</code> subtype)</li> |
| </ul> |
