{MODIStsp}
is a R
package devoted to automatizing the creation
of time series of raster images derived from MODIS Land Products data.
{MODIStsp}
allows performing several preprocessing steps (e.g.,
download, mosaicing, reprojection, resize, data extraction) on MODIS
data available within a given time period. Users have the ability to
select which specific layers of the original MODIS HDF files they want
to process. They also can select which additional Quality Indicators
should be extracted from the aggregated MODIS Quality Assurance layers
and, in the case of Surface Reflectance products, which Spectral
Indexes should be computed from the original reflectance bands.
All processing parameters can be easily selected with a powerful and
user-friendly GUI, although non-interactive execution exploiting a
previously created Options File is possible. Stand-alone execution
outside an R
environment is also possible, allowing using scheduled
execution of MODIStsp to automatically update time series related to a
MODIS product and extent whenever a new image is available.
For each output layer, outputs are saved as single-band raster files corresponding to each available acquisition date. Virtual files, allowing accessing to the entire time series as a single file, can be also created.
{MODIStsp}
was
developed by Lorenzo Busetto and Luigi Ranghetti, Institute of Remote
Sensing of Environment - National Research
Council - Italy (CNR-IREA). It is dedicated to the memory of
Lorenzo.
29/10/2021 - {MODIStsp}
(GitHub version 2.0.6.9000) supports
products with version 061. Version 006 will remain the default
product version until its decommission will be announced. Version
061 can be specified through the argument prod_version
of function
MODIStsp()
or by selecting it in the GUI.
10/12/2020 - {MODIStsp}
was resubmitted to CRAN after the
maintainer’s death. Now {MODIStsp}
is dedicated to Lorenzo Busetto
(https://docs.ropensci.org/MODIStsp/articles/lorenzo).
01/09/2020 - {MODIStsp}
2.0.0 is out. Replaces the old gWidgets
GUI with a new one based on Shiny, enhances support for CLI usage
and enhances support/provides bug fixing for datasets with multiple
NoData values when applying scale/offset.
09/05/2020 - {MODIStsp}
1.4.0 is out. Switches to use of
GDAL3/PROJ6 WKTs for projection representation and usage of {sf}
for all internal work on vector data. Adds support for products
MCD19A1 and MCD19A2 products.
07/06/2019 - {MODIStsp}
1.3.9 is out. Fixes a bug causing crashes
on MOD14A1 product, adds support for product MCD12Q2 and removes
support for no longer available version 5 of some products.
05/03/2019 - {MODIStsp}
1.3.8 is out. Fixes an issue causing
incorrect application of scale/offset values on GDAL versions > 2.3
(https://github.com/ropensci/MODIStsp/issues/163) and adds support
for products MOD21A1D.006 MOD21A1N.006 MOD21A2.006
.
29/11/2018 - We recently discovered a nasty bug in the computation of some custom spectral indices (those including additions / subtractions on reflectance values, such as in (with being a reflectance). See here for further details. The bug is now fixed on the GitHub version. A patched release will be made available on CRAN as soon as possible.
07/08/2018 - We are glad to report that {MODIStsp}
is now included
in the rOpenSci packages ecosystem.
We thank reviewers Leah Wasser and Jeffrey Hanson for their valuable
reviews, which helped us
further improving the package.
10/07/2018 - {MODIStsp}
v. 1.3.6 is out (check out the Release
Notes for
further details).
20/06/2018 - {MODIStsp}
v. 1.3.5 is out (check out the Release
Notes for
further details).
11/04/2018 - Due to new NASA Policies the MODIS FTP servers were shut down starting, April 2, 2018. FTP download is therefore no longer working and will be removed in the next MODIStsp version.
11/04/2018 - Decommissioning of MODIS Version 5 Land Data Products. As per NASA notice above, MODIS v005 products are going to be decommissioned, and will soon be no longer available for download. Support for those products will be removed in the next MODIStsp version.
11/08/2017 - {MODIStsp}
1.3.3 was released today. It provides
improvements in processing speed, as well as the usual bug fixes.
