[OSGeo-Discuss] Discuss Digest, Vol 89, Issue 2

Hi Jeff,

Anyone interested in contributing to the project is welcome to. They simply need to be added as a member of the project:

https://code.google.com/p/whitebox-geospatial-analysis-tools/

If you are interested, send me an email and I'll add you as a member so that you can commit code. I can also provide detailed instructions on how to get set up using Netbeans and SVN (I suppose other IDE would work too). There are also instructions in the tutorial 'Getting the Whitebox source code' which can be found in the Whitebox Help menu.

You can join the Whitebox listserv by sending a request email; instructions are here:

http://www.lsoft.com/scripts/wl.exe?SL1=WHITEBOX-GAT&H=LISTSERV.UOGUELPH.CA

The listserv is a good place to post questions about general use or development issues.

The reason I sent my previous email to you directly was because I wasn't sure if it would be of general interest to the listserv but if you think it is then that's great too.

Cheers,

John

Hi John,

Thanks for your response.  I guess my next question is how does the
community contribute to your project.  Please respond to this mailing
list so others can learn of your project.  Don't take my questions the
wrong way: that we are discussing your project on this OSGeo list is
great for your project's visibility.

Hello,

We are pleased to announce the release of the open-source GIS Whitebox Geospatial Analysis Tools 3.2.0 (http://www.uoguelph.ca/~hydrogeo/Whitebox/index.html). Whitebox now contains over 370 tools for performing advanced geospatial analysis. This version targets Java 8 and will require users to update their Java Runtime. Other changes include:

-Added a ClusterAttribute tool that performs k-means clustering on a selected group of attributes associated with a vector file.
-Added zoom to selection for vector layers.
-Added a Clip tool for vector clipping operations. I know, why has it taken this long?
-Added floating point line thicknesses and changed the default line thickness to 0.75. This has greatly improved the cartographic output of Whitebox.
-Added Export Table to CSV tool.
-Added Hack Stream Ordering and Topological Stream Ordering tools.
-Added Total Length of Upstream Channels tool.
-Added Furtherest Upstream Channel Head Distance tool.
-Added the Attribute Histogram tool for create histograms based on numeric data contained in a shapefile's attribute table as well as the Attribute Scattergram tool.
-Vectors can now be displayed with a palette rendered based on a boolean attribute.
-Added palette nonlinearity for vectors with a scaled palette.
-Fixed the raster-to-vector polygon conversion to include polygon holes.
-Modified the minimum bounding box tool, and all related tools (e.g. elongation ratio, long axis, short axis) to use an analytical solution for finding the MBB.
-Added a link to the Whitebox blog (http://whiteboxgeospatial.wordpress.com) in the help menu.
-Added the Vector Attribute Gridding tool, which can be used to interpolate the spatial pattern of average values of an attribute of vector features onto a raster grid. It essentially can be used to answer the question, of the vector features (points, lines, or polygons) within the a local neighbourhood, what is the average value of some attribute? This can be quite handy for visualizing patterns.
-Added the Vector Feature Density tool, which is similar to the Vector Attribute Gridding tool but works to map the spatial pattern of feature density (how many vector features are within a local neighbourhood?).
-Added the ability to rotate map titles. I know this isn't a proper labelling system yet, but I'm working on it. Hopefully map labels will be added this summer.

Please report any issues that you encounter as a result of this upgrade using the Whitebox menu, Help -> Report An Error.

Whitebox GAT is an example of an 'open-access GIS'. The concept of open-access software is based on the idea that software should be designed in a way that reduces the barriers that often discourage or disallow end-users from examining the algorithm design and implementation associated with specific geospatial tools. That is, open-access software encourages the educational opportunities gained by direct inspection of code. For more information see the link below:

As always, I hope you enjoy this new release and happy geoprocessing!

Hello John,

Congrats on your project release.  Keep in mind our foundation, OSGeo,
as it can help you move into the Open Source realm.  I'd note that it
took me a lot of time to find the (read-only) source for your project
(https://code.google.com/p/whitebox-geospatial-analysis-tools/), and I'm
not sure how to view your mailing list archives (I need to create an
account?).  OSGeo has resources to help your project, if you meet some
requirements (such as http://wiki.osgeo.org/wiki/OSGeo_Labs).  We are
always happy to help projects grow.

Thanks for sharing.
