The most important features and enhancements introduced in BEAM 4.7 are summarized here:
- VISAT now provides a Geometry Management allowing users
to draw and manipulate geometries (vector data) or to import them from ESRI Shapefiles.
Geometries are now an integral part of the BEAM data model.
- The VISAT Mask and ROI Management has been revised completely.
Any number of raster data masks can be defined by band maths expressions, value ranges and
existing geometries. Each mask can serve as a region of interest (ROI) for raster data analysis.
- The Statistics, Histogram,
and Scatter Plot tool windows have been enhanced in order to support the
new, named ROIs.
The Statistics tool window can now operate on multiple ROIs.
- The
Reprojection (formerly 'Map Projection'),
Mosaicing and
Orthorectification processors have been redesigned from scratch.
Due to the great GeoTools library, BEAM now offers more than
100 predefined, map projections based on their EPSG
codes. For user-defined map projections you can now select from 25 map projection
transformations and more than 100 geodetic datums. Since the new Reprojection, Mosaicing and
Orthorectification processors are developed using the BEAM Graph Processing Framework (GPF), they now
offer a powerful command-line and can be used in any GPF XML processing graph for, e.g., pre-
and post-processing.
Finally, the runtime performance of this tools has been drastically improved.
- The Navigation tool window has been improved. It is now feasible
to display a synchronized pixel cursor in all image views.
- The World Map tool window has been completely revised. It now uses a
higher-resolution RGB (NASA Blue Marble) in which you can easily pan and zoom in and out.
