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
