Hello all As part of Hao's work on Google Summer of Code, we have a partial mapping from Landsat to ISO 19115 metadata. The mapping is temporarily documented here (will be moved to Apache SIS javadoc later):
http://htmlpreview.github.io/?https://raw.githubusercontent.com/desruisseaux/sis/JDK8/storage/sis-geotiff/src/main/java/org/apache/sis/storage/geotiff/doc-files/LandsatMetadata.html We will complete this mapping progressively. Does anyone has comment? Note for Hao: we have a slight mismatch between the Landsat and ISO 19115 geographic bounding box. For example the Landsat CORNER_UL_LAT_PRODUCT is: The latitude value for the upper-left corner of the product, _*measured at the center of the pixel*_. Positive (+) value indicates north latitude; negative (-) value indicates south latitude. Units are in degrees. While ISO 19115 northBoundLatitude is: Northern-most coordinate of the _*limit of the resource extent*_ expressed in latitude in decimal degrees (positive north). Between the two, there is a difference of 0.5 pixels. It may look small, but a pixel of a remote sensing image may cover an area of some kilometres on Earth. Martin
