Bug Fixes

  • Fixed a number of problems with geolocation of Palsar L1.1 (SLC)

Known Issues

  • KML overlay generation fails for images that cross the dateline.
    • Workaround: Turn off thumbnail & overlay generation for these files. OR Ignore the error, the desired output file has been generated even though the processing resulted in an error and didn't move to “Completed”.
  • Unable to “Add Output File Prefix or Suffix” for PolSARPro Covariance matrix files
    • Workaround: Do not use the feature for these files.
  • MapReady does not always warn me if I am about to overwrite previous files.
    • Additional Info: This can occur when the input has multiple bands that each need to be calibrated, so that you get multiple output files with band suffixes appended.
    • Workaround: When re-processing files, make sure you've saved any files from previous runs.
  • MapReady does not always delete intermediate files
    • Additional Info: During processing, MapReady creates a temporary directory in the directory where the final output will be put, containing intermediate files. Sometimes these directories are not cleaned up properly after processing.
    • Workaround: They can be ignored, however if disk space becomes an issue they can be deleted manually.
  • Thumbnails are not generated for all product types
    • Additional Info: For AirSAR, ALOS Mosaic files, and some UAVSAR files, the input and output thumbnail are not generated in the GUI.
    • Workaround: Use “View Input” or “View Output” to look at the files.
  • 'Error: This data cannot be calibrated, missing calibration block.' encountered while attempting to generate a Sigma Radiometry image of AirSAR data
    • Additional Info: AirSAR data is already calibrated, and MapReady cannot re-calibrate it. The GUI should prevent attempting to do so but currently does not.
    • Workaround: Do not attempt to calibrate AirSAR data, it is not necessary.
  • Unable to open a file in the Completed Files section in Google Earth
    • Additional Info: In the MapReady console window, you will see the name of the KML file MapReady is trying to open. Sometimes, this is not the name of the actual KML file that was generated.
    • Workaround: Go to the output directory, and double-click the actual KML file to open it in Google Earth.
  • Faulty error message for PolSARPro data with colormap and export to floating point GeoTIFF
    • Workaround: In Export tab, check Output data in byte format (instead of floating point)
  • Pixel values of radiometrically terrain corrected PolSARPro T3 matrix differ greatly from those of geometrically terrain corrected T3 matrix
    • Workaround: Not supported for PolSARPro files.
  • Calibration of all PolSARPro files processed exhibits unexpected values
    • Workaround: Calibration is not necessary for PolSARPro files.

MapReady 1.0.2 (released 2008 January 2)

New Functionality (GUI and command-line tools)

  • Convert GUI name changed to MapReady and redesigned and reorganized
    the user interface for more intuitive use, advanced tool tips,
    improved help. Command line version, asf_convert, renamed to
    asf_mapready.
  • New Tool : Added new SAR and Optical image viewer (asf_view).
    Replaces, modernizes, and enhances capabilities previously found
    in the now-unsupported sarview tool, allows viewing geographic
    region covered by the dataset in Google Earth, and applies
    pseudo-color according to look-up tables available from a drop-down
    list.
  • New Tool : Added shift_geolocation (command line) to the tool set.
    Allows manual shifting of geolocation if a known offset exists.
    Similar to refine_geolocation but no DEM is required.
  • New Tool : Added Projection Coordinate Converter (GUI) to the tool
    set. This tools converts projection coordinates in one map
    projection into projection coordinates in another map projection.
    The GUI allows you to specify map projection parameters, manually
    enter coordinates, or select a file that contains coordinate triplets (x, y, height) - one triplet per line. Results can be saved to a file as well.
  • New Tool : Added 'trim', a simple command-line utility that facilitates subsetting an ASF Internal Format file given starting line, number of lines, starting sample, and number of samples.
  • New Tool : Added 'fill_holes', a tool that replaces values in an image below a given cut-off with values interpolated from the shape and height of the surrounding terrain. The fill_holes tool is handy for manually patching 'holes' (regions with no-data values, typically very small negative values) in DEMs prior to using the DEM for terrain correction. The result is that hole-related artifacts in terrain corrected images are minimized (available as a command-line flag to asf_mapready and as a checkbox in MapReady as well.)
  • New Tool : The 'to_sr' tool has been added to the tool suite. The to_sr tool converts a ground range (or map-projected ASF Internal format image with state vectors available in the metadata file) into a slant-range image. Replaces deprecated gr2sr tool.
  • New Tool : The 'deskew' tool has been added to the tool suite. The deskew too removes satellite platform squint-induced skew from ground range images.
  • Enhanced TIFF/GeoTIFF ingest to support a much broader spectrum of GeoTIFF types (scanline, tiled, striped, color; geocentric lat/long in decimal degrees)
  • Added support for several new CEOS data formats (BEIJING ESA raw, CDPF)
  • Terrain correction of ScanSAR and ALOS Palsar
  • Sinclair decomposition upon export for real-valued radar images
  • Added 'Display in Google Earth' buttons to the GUI for viewing of the data extents in the Google Earth (tm) program.
  • Added ability to patch 'holes' (interpolate over missing data) in DEMs. Also see new tool 'fill_holes'.
  • Ability to export PNG graphics file format

Bugs Fixed

  • Resolved some minor memory leaks
  • shift_geolocation now works properly on map-projected images
  • Fixed several (minor) metadata inconsistencies
  • Resolved 700m to 1.5km geolocation offset which occurred in some ALOS AVNIR2 images
  • Resolved file seek error which occurred when importing into a sigma nought power image
  • Resolved band_count error when importing GeoTIFFs with empty color channels

  • Resolved issues with geocoding images that cross the zone 1to 60 boundary in UTM map-projections.
  • Resolved minor inaccuracies in ScanSAR alpha-rotation projections.

Features Enhanced

  • Improved Windows registry settings to allow parallel installations of multiple versions of the tool set (including uninstallation)
  • Import of polar stereographic SSM/I CEOS data now defaults to utilizing the Hughes reference spheroid
  • Enhanced import/export of image bands (channels, polarizations, etc)
  • Added support in the command line version of asf_convert for exporting individual bands from multi-band files
  • Improved JPEG output (reduced JPEG artifacts)
  • Metadata now includes location block (corners, center, lat/long)
  • Made input file name specification more flexible and removed some dependencies on the name of the file (less error prone)
  • Added support for a broader variety of input file naming conventions
  • Added support for bicubic resampling during geocoding of byte images
