Although we are just getting started, we've added articles on using the new Gridfour Virtual Raster Store (GVRS) API. GVRS is only part of the Gridfour library which include tools for processing numerical raster data. We've currently implemented interpolation logic based on B-Spline algorithms and are working to include tools such as contouring, statistical analysis, and other techniques.

You may access this wiki's content by clicking on the list of articles in the panel on the right side of this page.

• The "GVRS Jump Start" articles provide a getting-started guide for creating applications that use the GVRS API. data, to storing it in GVRS, the the advanced topic of writing custom data compression.
• The "How-To" articles cover both the GVRS API and other topics in added detail.
• Future articles will provide additional discussion of the utilities provided through the Gridfour Software Project.

In addition to Gridfour-focused subject matter, our Gridfour Application Notes page also covers related topics. Even if you are not using Gridfour, you may find information on our Users Notes page that assists you in working with raster data. Our notes pages cover everything from data-compression algorithms for raster products, to rendering techniques, and even to articles that tell how to extract data from public information sources in formats such as GeoTIFF and NetCDF.

The Gridfour Core module is built under Java 8 and has no external depencies beyond the Java standard API. Gridfour binaries (Jar files) are now available from the Maven Central Repository of your choice. Our latest version, 1.0.1, is available as GridfourCore-1.0.1.jar. To include Gridfour as a dependency in a Maven pom.xml, you may use the following specification:

<!-- https://mvnrepository.com/artifact/org.gridfour/GridfourCore -->
<dependency>
    <groupId>org.gridfour</groupId>
    <artifactId>GridfourCore</artifactId>
    <version>1.0.1</version>
