In debangs/RSAGA: SAGA Geoprocessing and Terrain Analysis in R

RSAGA News

07 January 2016

RSAGA 0.94-5 is now available on CRAN. This release is largely version updates to support SAGA GIS 2.2.3

08 November 2015

RSAGA 0.94-4 is now available on CRAN. Included in this release are updates to support SAGA GIS versions 2.2.1 and 2.2.2

An additional function rsaga.pisr2 has been added to support the Potential Incoming Solar Radiation module with SAGA 2.2.2

Unix note - on some systems users have reported that rsaga.* functions with SAGA 2.2.0+ produce a warning message: "Error: select a tool". This can be suppressed by adding the argument check.module.exists = FALSE until the bug is addressed.

27 August 2015

RSAGA 0.94-3 is now available on CRAN. Included in this release are updates to support SAGA GIS version 2.2.0

An introductory vignette and associated data file landslides are now included with RSAGA. The vignette demonstrates how to initialize and run RSAGA, perform terrain analysis, and execute RSAGA grid functions using an example of generalized additive modeling for landslide susceptibility modeling with the included dataset.

09 June 2015

RSAGA 0.94-1 is now available on CRAN. Updates to the package support changes in SAGA GIS, particularly from SAGA version 2.1.0 to 2.1.4.

N.B.: Some changes may affect older code:

1. Arguments and calculations using the Slope, Aspect, Curvature module have changed with SAGA 2.1.1+
2. New function rsaga.slope.asp.curv has been added for use with SAGA 2.1.1+
3. Continue to use rsaga.local.morphometry with SAGA versions below 2.1.1
4. Calls using rsaga.local.morphometry with SAGA 2.1.1+ are redirected to rsaga.slope.asp.curv
   • An additional method has been added in rsaga.slope.asp.curv, in the 3 position. Numeric arguments for method are not supported with this function, and will stop with an error message.
5. Plan and profile curvature calculations have changed with SAGA 2.1.1+. See [SAGA forum discussion] (http://sourceforge.net/p/saga-gis/discussion/354013/thread/e9d07075/?limit=25#5727) for details.

6. rsaga.slope, rsaga.aspect, rsaga.curvature, rsaga.plan.curvature, and rsaga.profile.curvature use either rsaga.slope.asp.curv (version 2.1.1+) or rsaga.local.morphometry (version < 2.1.1).

7. Parallel Processing (Terrain Analysis - Hydrology) no longer in SAGA 2.1.3+, replaced with Top-Down Processing. rsaga.parallel.processing is not supported with SAGA 2.1.3+. See rsaga.topdown.processing for a similar function.

8. The handling of Boolean parameters has changed with SAGA 2.1.3+. When using rsaga.geoprocessor, not passing a Boolean parameter will leave it as default, not necessarily FALSE. See more details in [SAGA Release Wiki] (http://sourceforge.net/p/saga-gis/wiki/Compatibility%202.1.3/).
