_GeoTrellis_ is a Scala library and framework that provides
APIs for reading, writing and operating on geospatial
raster and vector data. GeoTrellis also provides helpers
for these same operations in Spark and for performing
[MapAlgebra](https://en.wikipedia.org/wiki/Map_algebra)
operations on rasters. It is released under the Apache 2 License.

Please visit the **[project site](http://geotrellis.io)**
for more information as well as some interactive demos.

You're also welcome to ask questions and talk to developers
(let us know what you're working on!) via [Gitter](https://gitter.im/geotrellis/geotrellis).

## Getting Started

GeoTrellis is currently available for Scala 2.13 and 3, using Spark 4.2.x.

To get started with SBT, simply add the following to your build.sbt file:

```scala
libraryDependencies += "org.locationtech.geotrellis" %% "geotrellis-raster" % "<latest version>"
```

To grab the latest `SNAPSHOT`, `RC` or milestone build, add these resolvers:

```scala
// maven central snapshots
resolvers ++= Seq(
  "central-snapshots" at "https://central.sonatype.com/repository/maven-snapshots/"
)

// or eclipse snapshots
resolvers ++= Seq(
  "eclipse-releases" at "https://repo.eclipse.org/content/groups/releases",
  "eclipse-snapshots" at "https://repo.eclipse.org/content/groups/snapshots"
)
```

If you are just getting started with GeoTrellis, we recommend familiarizing yourself with the
`geotrellis-raster` package, but it is just one of the many available. The complete list
of published GeoTrellis packages includes:

- `geotrellis-accumulo`: Accumulo store integration for GeoTrellis
- `geotrellis-accumulo-spark`: Accumulo store integration for GeoTrellis + Spark
- `geotrellis-cassandra`: Cassandra store integration for GeoTrellis
- `geotrellis-cassandra-spark`: Cassandra s
