Handling and Manipulating Remote Sensing Data

Herein, we provide a broad variety of functions which are useful for handling, manipulating, and visualizing satellite-based remote sensing data. These operations range from mere data import and layer handling (eg subsetting), over Raster* typical data wrangling (eg crop, extend), to more sophisticated (pre-)processing tasks typically applied to satellite imagery (eg atmospheric and topographic correction). This functionality is complemented by a full access to the satellite layers' metadata at any stage and the documentation of performed actions in a separate log file. Currently available sensors include Landsat 4-5 (TM), 7 (ETM+), and 8 (OLI/TIRS Combined), and additional compatibility is ensured for the Landsat Global Land Survey data set. Moreover, support for Terra and Aqua-MODIS as well as PROBA-V is expected to arrive shortly.

News

satellite 1.0.1

Bugfixes:

  • calcAtmosCorr() was not compatible with NA values, ie quantile() failed.
  • compFilePathLandsat() failed when specifying metadata files with new naming standard as input.
  • compMetaLandsat() assigned Landsat 7 metadata information, eg parameters required for radiometric rescaling, to wrong bands.

satellite 1.0.0

New features:

  • Inverse squared relative earth-sun distance from calcEarthSunDist().
  • calcTopoCorr,Raster*() methods accept additional arguments (via '...') passed to writeRaster().
  • crop,Satellite-method takes a new argument 'snap' similar to raster::crop().
  • extend,Satellite-method takes a new argument 'value' which is assigned to new cells similar to raster::extend().
  • satellite is compatible with pre-collection Level-1 and Collection 1 Level-1 file naming.
  • sortFilesLandsat() to automatically sort Landsat band files in ascending order.

Bugfixes:

  • plot,Satellite-method ignored band codes to be visualized if 'bcde = ' assignment was not explicitly included.
  • Solved 'Error in .local(.Object, ...) :' when trying to retrieve values from built-in data sets l7, l8.

Changes:

  • calcHistMatch() and panSharp() moved to satelliteTools (https://github.com/environmentalinformatics-marburg/satelliteTools).
  • Mandatory use of Rcpp functionality in calcPathRadDOS().
  • Added helper functions in R/pck_data.R and R/pck_lut.R to .Rbuildignore.
  • Revised sensor IDs for Landsat 4 (LT4 for 'Landsat Thematic Mapper') and 5 (LT5).
  • Updated ESun values (https://landsat.usgs.gov/esun) for Landsat 4, 5 and 7.
  • Updated spectral range of Landsat 7 band 7 (https://landsat.usgs.gov/landsat-7-history).
  • Moved Rcpp from Depends to Imports.
  • Built-in data sets l7, l8 now originate from Landsat Collection 1 Level-1 instead of previous Pre-Collection 1 Level-1.
  • Removed deprecated convDN2RU(), users must switch to convSC2Rad(), convSC2Ref() and convRad2BT() instead.
