azavea/raster-vision

Raster Vision is an open source Python library and framework for building computer vision models on satellite, aerial, and other large imagery sets (including oblique drone imagery).

It has built-in support for chip classification, object detection, and semantic segmentation with backends using PyTorch.

As a library, Raster Vision provides a full suite of utilities for dealing with all aspects of a geospatial deep learning workflow: reading geo-referenced data, training models, making predictions, and writing out predictions in geo-referenced formats.

As a low-code framework, Raster Vision allows users (who don't need to be experts in deep learning!) to quickly and repeatably configure experiments that execute a machine learning pipeline including: analyzing training data, creating training chips, training models, creating predictions, evaluating models, and bundling the model files and configuration for easy deployment.

Raster Vision also has built-in support for running experiments in the cloud using AWS Batch.

See the documentation for more details.

Installation

For more details, see the Setup documentation.

Install via pip

You can install Raster Vision directly via pip.

pip install rastervision

Use Pre-built Docker Image

Alternatively, you may use a Docker image. Docker images are published to quay.io (see the tags tab).

We publish a new tag per merge into master, which is tagged with the first 7 characters of the commit hash. To use the latest version, pull the latest suffix, e.g. raster-vision:pytorch-latest. Git tags are also published, with the Github tag name as the Docker tag suffix.

Build Docker Image

You can also build a Docker image from scratch yourself. After cloning this repo, run docker/build, and run then the container using docker/run.

Usage Examples and Tutorials

Non-developers may find it easiest to use Raster Vision as a low-code framework where Raster Vision handles all the complexities and the user only has to configure a few parameters. The Quickstart guide is a good entry-point into this. More advanced examples can be found on the Examples page.

For developers and those looking to dive deeper or combine Raster Vision with their own code, the best starting point is Usage Overview, followed by Basic Concepts and Tutorials.
