New in SNAP v3.0

New Features and Important Changes

  • A new Resampling Operator has been introduced. Its main purpose is to make the bands of a multi-size product equal in size. It is possible to choose for the resampling different aggregation and interpolation methods. If a user invokes an action which can not handle multi-size products the user is asked to resample the product.
  • New function bit_set(bandName, bitNumber) in Band Maths available. The method tests if the bit at the specified number is set or not.
  • GPF operators can now compute multi-size target products. To do so the computeTile(band, tile) must be implemented. In order to reflect a dynamic state created in the initialize() method (the source and therefore the target is single-size) the methods boolean canComputeTile() and boolean canComputeTileStack() can be overridden.
  • GPF operators can now access a product manager Operator.getProductManager(). This is useful to provide auxiliary products to other operators in the graph.
  • Support for quicklooks have been integrated in Products Explorer and Product Library
  • Operations to perform land masking have been added.
  • The operator LinearTodB has been renamed to LinearToFromdB
