About this Software

clj-span is an implementation of the Service Path Attribution Networks (Springer LNCS 2010 - Johnson et al.) framework for Ecosystem Service Assessment.

Using clj-span, you can run a collection of parameterizable SPAN flow simulation models (line-of-sight, proximity, carbon, flood-water, surface-water, sediment, coastal-storm-protection, and subsistence-fisheries) and visualize their results as map outputs.

Usage

To run clj-span, you will need:

1. Sun’s JDK 1.7+
2. clj-span-standalone.jar (contains clojure-1.5.1)

Then simply place clj-span-standalone.jar on your classpath and fire up your JVM as follows:

java -cp clj-span-standalone.jar clj_span.commandline \
     -config-file        <filepath>                 \
     -source-layer       <filepath>                 \
     -sink-layer         <filepath>                 \
     -use-layer          <filepath>                 \
     -flow-layers        <filepath>                 \
     -source-threshold   <double>                   \
     -sink-threshold     <double>                   \
     -use-threshold      <double>                   \
     -trans-threshold    <double>                   \
     -cell-width         <double>                   \
     -cell-height        <double>                   \
     -rv-max-states      <integer>                  \
     -downscaling-factor <number>                   \
     -source-type        <finite|infinite>          \
     -sink-type          <finite|infinite>          \
     -use-type           <finite|infinite>          \
     -benefit-type       <rival|non-rival>          \
     -value-type         <numbers|varprop|randvars> \
     -animation?         <true|false>               \
