THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!
Introduction
Apache SIS is a spatial framework that enables better representation of coordinates for searching, data clustering, archiving, or any other relevant spatial needs. SIS is undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator PMC.
Downloading & Building SIS
The latest released source code can be obtained by visiting the downloads page. You can download the 'apache-sis-src.tar.gz' archive and run the following commands to unpack it to a local folder, for example as follows:
mkdir /usr/local/src mkdir /usr/local/src/sis-site tar xzvf apache-sis-src.tar.gz -C /usr/local/src/sis-site
You can also check out the latest code from the SIS Subversion repository. Below is an example command to get the latest code and copy it to folder /usr/local/src/sis-site:
mkdir /usr/local/src svn checkout http://svn.apache.org/repos/asf/incubator/sis/trunk /usr/local/src/sis-site
SIS is based on Java 5 and uses the Apache Maven (version 2) build system. Once you have obtained the source files, to build SIS, run the following command from within the top source directory (e.g. /usr/local/src/sis-site):
mvn clean install
Eclipse Integration
svn co https://svn.apache.org/repos/asf/sis/trunk/ sis-site cd sis-site mvn test # this will deploy the test resources and download and build necessary libraries mvn eclipse:eclipse
Open eclipse in a new workspace.
Go to Eclipse->Preferences->General->Workspace
Change Text file encoding to Other: UTF-8, Apply, Ok
Go to File-> Import -> General -> Existing Projects in Workspace
Choose the sis directory and import
NetBeans Integration
See https://builds.apache.org/job/sis-trunk/site/develop.html.
Running The SIS Web Application
The build consists of a number of components, including a web-based application that you can use to try out SIS features. Below are some instructions on how to set up the web application on various different servers.
Running on Jetty
Jetty is now supported as of 11th February 2012. After building SIS, navigate to the sis-webapp directory. To run the built-in Jetty server, run the following command:
mvn jetty:run
Running on Tomcat
There are several different versions of Apache Tomcat available, each with different requirements for installing web applications. For more details, please refer to the documentation for the specific version of Tomcat that you're running. Below is a set of instructions for a very simple installation on Tomcat 7. In the following examples, please replace $TOMCAT_HOME with the location of your Tomcat 7 installation.
Shut down Tomcat if it's already running:
$TOMCAT_HOME/bin/shutdown.sh
Copy the SIS web application from the SIS build directory to the Tomcat web applications directory. The SIS web application can be found in the 'sis-webapp/target' directory within your SIS source directory. The web applications directory for Tomcat 7 is by default '$TOMCAT_HOME/webapps'. For example, the following command will copy the SIS web application directory to the Tomcat webapps directory and rename it to 'sis'.
cp -R /usr/local/src/sis-site/sis-webapp/target/sis-webapp /$TOMCAT_HOME/webapps/sis
Create the following directories to store data returned from SIS queries. These can be created anywhere you like. The example below creates them within the SIS webapp directory:
mkdir $TOMCAT_HOME/webapps/sis/qtree mkdir $TOMCAT_HOME/webapps/sis/geodata
Edit the '$TOMCAT_HOME/webapps/sis/WEB-INF/web.xml' file and add references to your data directories as follows:
<context-param> <param-name>org.apache.sis.services.config.qIndexPath</param-name> <param-value>/$TOMCAT_HOME/webapps/sis/qtree</param-value> </context-param> <context-param> <param-name>org.apache.sis.services.config.geodataPath</param-name> <param-value>/$TOMCAT_HOME/webapps/sis/geodata</param-value> </context-param>
Modify the parameter for 'org.apache.sis.services.config.filePath' to point to the location of your 'sis-location-config.xml' file. By default, this is located in the 'WEB-INF/classes' directory of the SIS web application:
<context-param> <param-name>org.apache.sis.services.config.filePath</param-name> <param-value>/$TOMCAT_HOME/webapps/sis/WEB-INF/classes/sis-location-config.xml</param-value> </context-param>
You can use the 'sis-location-config.xml' file to configure the RSS feeds that SIS will process. Feeds can be added by inserting their URLs into the 'sis-location-config.xml' file between <url> ... </url> tags, as in the following example:
<url>http://earthquake.usgs.gov/earthquakes/catalogs/shakerss.xml</url>
After making the above changes to the SIS web application configuration files, restart Tomcat with the following command:
$TOMCAT_HOME/bin/startup.sh
Demonstration
A demonstration is included with the SIS webapp. The 'demo.jsp' file can be found in the sis-webapp top level folder. It can be accessed via a web browser by navigating to http:////demo.jsp, where <host> is the address of your chosen server and <webapp> is the name of the top level SIS webapp directory, for example http://localhost:8080/sis/demo.jsp.
On loading the page, you should see the Apache SIS logo, a simple form and a map. Use the form to enter some queries and return results from RSS feeds to SIS on the map. Below are two example queries to try:
Bounding Box: Lower Left: Latitude: 0, Longitude: 50 Upper Right: Latitude: 50, Longitude: 100
Point Radius: Latitude: 0 Longitude: 80 Radius: 400km
Mailing Lists
Discussion about SIS takes place on the following mailing lists:
- sis-user@incubator.apache.org - about using SIS
- sis-dev@incubator.apache.org - about developing SIS
- sis-commits@incubator.apache.org - notifications on all code changes for SIS
The mailing lists are open to anyone and publicly archived.
