Summary

Add support for geometric ortho-rectification to SAR Sensor for Sentinel-1.

Rationale

This task continues efforts started in RfCh-4. Only the radiometric calibration was done, geometric calibration has been added to conform to inverse SAR geolocation method found in ESA document "Guide to ASAR geocoding" (ref RSL-ASAR-GC-AD).

Implementation details

Classes and files

misc
M       Modules/Core/Metadata/src/otbSarImageMetadataInterface.cxx
M       Modules/Core/Metadata/src/otbSentinel1ImageMetadataInterface.cxx
M       Modules/IO/ImageIO/include/otbImageFileReader.txx
Boost dependencies
M       .travis.yml
M       Modules/ThirdParty/Boost/otb-module-init.cmake
M       SuperBuild/CMake/External_boost.cmake

Several issues have been fixed here:

  • First, travis needs to know that boost is required to compile
  • Then, it's important to never call find_package(boost) several times. The later calls will clear everything that was found initially. If an initial call was searching for a given mandatory boost module (like date-time), and a second and optional call searches for an optional module (like tests), then the first module found is lost.
OSSIMAdapters
M       Modules/Adapters/OSSIMAdapters/include/otbImageKeywordlist.h
M       Modules/Adapters/OSSIMAdapters/include/otbSensorModelAdapter.h
M       Modules/Adapters/OSSIMAdapters/src/otbImageKeywordlist.cxx
M       Modules/Adapters/OSSIMAdapters/src/otbSensorModelAdapter.cxx

As some keywords have been moved around, and as dates are now always stored as ISO UTC time stamps, OTB code has been upgraded to reflect the changes in ossim plugins.

Several utilities has been added to prevent code repeats, and to be as fast as possible.

  • new string_view class inspired by C++17 one
  • new overloads for a generic and type safe (de)serialization to/from keyword lists
  • new overloads for a generic and type safe deserialization to/from XML docs
  • new ModifiedJulianDate class + an efficient and simplified implementation of strptime
  • Helper classes to define arithmetic types (inspired from boost.operators, but specialized for times and durations)
