BlueSpray
• A GIS application for environmental science and natural resource management
• Includes tools for modeling:– HEMI– Maxent regression optimization– Statistical tests
• AIC, AICc, BIC, Likelihood• Pearson’s and Spearman’s
– Random dataset generation• Based on OpenSource and custom code
BlueSpray Ownership
• Owned by SchoonerTurtles.com– Which is owned by Jim Graham
• Currently in “beta” testing• Free to beta testers• Need a passcode which changes once a
year• Plan on continuing to provide BlueSpray
at little or no cost for environmental science research academics and non-profits
BlueSpray Expansion
• BlueSpray was build to be a platform for GIS software development:– File handlers– Transforms– “Painters”– Layer types– Tools (things you use with your “hand” like
pointers, magnifying classes, brushes, etc.)– Etc.
BlueSpray and Java
• Runs on MS-Windows, Mac, and UNIX• Java is not slow, but programmers can
make it that way (i.e. BlueSpray is fast)• Need to have Java 7 installed• Free, OpenSource• Managed by Oracle and Java.net
Installing Java
• Follow the instructions at www.schoonerturtles.com
• There are two versions of Java:– 32-bit: can run on 32 or 64-bit OSes– 64-bit: can only run on 64-bit Oses
• Recommended to only install one version of Java
• Install Java 3D if you want to visualize data in 3D (under development)
Installing BlueSpray
• Download from www.schoonerturtles.com
• Uncompress the zip file• That’s it!
Running BlueSpray• Java programs run under a “virtual
machine”– Needs to know the min/max memory– Also needs to know the location of dynamic
linked libraries (DLLs)– There are different DLLs for 32-bit and 64-
bit
BlueSpray64.bat
• java : virtual machine• -Djava.security.policy=applet.policy
– To run applets• -Xms512m : minimum memory• -Xmx4024m : maximum memory• Djava.library.path=..\BlueSpray\
STLibraries64 – Path to DLLs
• -jar BlueSpray.jar : program to run
Learning BlueSpray
• See the documentation that comes with BlueSpray– It’s minimum at this point– Let me know what is needed and I’ll add &
edit
BlueSpray for Modeling
• Optimal regularization and uncertainty maps for Maxent
• Quick creation of tabular files– Extract… in attributes
• Quick conversions between points and rasters
• Statistical tests• HEMI
