Presentation Transcript

  1. 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

  2. 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

  3. 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.

  4. 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

  5. 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)

  6. Installing BlueSpray • Download from www.schoonerturtles.com • Uncompress the zip file • That’s it!

  7. 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

  8. BlueSpray Launcher

  9. 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

  10. 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

  11. 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
