Linkage Mapper Version 3.1 Beta

New since Version 3.0.0:

• Updated code to run in latest versions of ArcPro, versions 3.x (Python changed the syntax of time.)
• Update that makes it possible to run tools in batch from Python scripts. Helpful for testing.
• Fix to the Coarsen Raster Sizes utility to allow it to work with rasters that have file extensions not just raster grids.
• Fixed a bug in Pinchpoint mapper that arises for certain edge cases.
• Further refined the use of (time) in ArcPro, versions 3.x and higher

Thank you to Darren Kavanagh for coding these improvements, and to Fred Watson for finding and sharing the initial solution to the ArcPro 3.0 bug.

Note: This is a "Beta" release, and it has the documentation as word files instead of .pdfs and the directory structure is not the same as the production version. If anyone wants to make the production ready "Beta2" version from this one by saving the word docs as .pdfs and mirroring the file structure Version 3.0, please do so and email john.gallo@linkagemapper.org, or make a new branch and submit it as a .zip file pull request.

Linkage Mapper Version 3

What is new in v3.0.0?

• Compatibility with ArcGIS Pro
• Linkage Priority Tool improvements (see next newsletter item)
• User Guide improvements
• Back-end engineering and code refactoring
• Re-writing of the GitHub commit history to make the repository smaller
• Improved Error Messages and Log Files
• Climate-wise Connectivity Improvements in Version 3.0.0

There are many climate considerations that can be incorporated in habitat connectivity modeling and mapping. Two considerations have previously been modeled in isolation from each other, and yield quite different recommendations for linkage priority. However, we discovered that they are two ends of the same continuous framework, and Linkage Mapper Version 3.0.0 allows the user to model for one, or the other, or an appropriate blend between both (which we recommend). The first consideration is “range shift connectivity”, and gives linkages a higher priority for conservation if they are predicted to connect a core area that might become too hot/dry in the future with a core that is expected to be much cooler/wetter. The other is “climate analog connectivity” giving higher priority to linkages with the destination core having the same predicted climate at a future time (e.g. 2050), as the climate in the source core at the current time. We also added “preferred climate” as an optional parameter in differentiating among destination cores.

Linkage Mapper v3.0.0-beta.6

The beta 6 release updates the demos and includes fixes for issues #117 and #118. It also includes the follow updates from earlier betas:

Beta 5
Fix to ordering of Blended Priority Options

Beta 4
Fixes for stick files and mosaicked rasters

Beta 3
Support for ArcGIS Pro

Beta 2

• New climate priority functionality
• The help dialogs in the Graphical User Interface have been updated
• Some fundamental changes to the linkage priority algorithm that:
  • Cleans up the way that overlapping paths of differing priority get mapped. Figures and specifications are in (#53)
  • Cleans up the way that the lee side of habitat concentration areas (cores) gets mapped. Originally, these had a much higher carryover effect than now. Figures and specifications are in ( #54)
• A performance improvement: 8e60148
• Some of the sub-model names in the .tbx were cleaned up to remove the extra "(2)"s added over time, and red x's in the alpha tools.
• Improved formula for calculating permeability so that the outliers are not so extreme, yielding a more normal distribution
• Updated user guide capturing many of the above additions.
• Addition of help statements for each new parameter in the toolbox.
