prismaread 0.2.0 - 2019-06-04

  • Major changes

    • prismaread now applies a GLT-based georeferencing to L1, L2B and L2C data, based on the technique described in https://www.harrisgeospatial.com/docs/backgroundgltbowtiecorrection.html

    • Added functionality to create also outputs about acquisition angles and Lat/Lon;

    • Added the prisma_extract_spectra function to facilitate extraction of PRISMA data over features of vector files;

    • Added possibility to extract only some bands, using the selbands_vnir and selbands_swir arguments to convert_prisma;

    • Removed the out_file argument, in favour of the out_folder and out_basefile arguments (see documentation);

  • Other changes

    • Miscellaneous bug fixes and optimization
    • Added pkgdown website

prismaread 0.1.0 - 2019-03-25

  • First beta “stable” version with several improvements

    • Proper conversion of L2D/L2C data, with results as reflectances after applying rescaling from the 0-65535 range

    • Proper conversion of L2B data, with results as radiances after applying rescaling from the 0-65535 range

    • Automatic application of scale and offset on L1 data, with results as radiances

    • Added argument base_georef to turn “ballpark” georeferencing of L1, L2B and L2C data on or off. Also, improved results thanks to proper checking of corners

    • Check for proper “orientation” of imported L1, L2B and L2C data

    • Avoid saturation problems on L1 data by changing output data type

  • Added a NEWS.md file to track changes to the package.

prismaread 0.0.2 - 2019-10-02

  • First draft version
