MODISExtra: Access and extract MODIS imagery.

In antoinestevens/MODISExtra: Download and extract MODIS imagery

Description

This package complements and replaces some of the functions of the MODIS package (v0.10-31; https://r-forge.r-project.org/R/?group_id=1252) For the functions that are replaced, most of the code is simply copy-pasted from the MODIS package, with a few bugs corrected and some changes to address specific needs.

Functions that are replaced

• getHdfModifications are only related to the way MODIS files are downloaded

• runGdalUse gdalUtils to simplify the code, with a few bugs corrected

• orgTimeAllows to define user-defined output time stamps with the nDays argument

• filesUrlUse rvest instead of RCurl package

New functions

• convert_modisConvert MODIS files to a Raster-class object

• convert_dn_modisConvert DN to physical values

• interpolate_rasterInterpolate Raster* time series, possibly to new time stamps (temporal resampling)

• gapfill_rasterFill gaps in Raster* time series

• convert_qf_modisExtract Quality Flags

Note

Function arguments follow the same naming as in MODIS, as much as possible. The package should be attached AFTER the MODIS package.
