**A Python package for segmenting geospatial data with the Segment Anything Model (SAM)**

## Introduction

The **SamGeo** package draws its inspiration from [segment-anything-eo](https://github.com/aliaksandr960/segment-anything-eo) repository authored by [Aliaksandr Hancharenka](https://github.com/aliaksandr960). The primary objective of SamGeo is to simplify the process of leveraging SAM for geospatial data analysis by enabling users to achieve this with minimal coding effort. The source code of SamGeo was adapted from the [segment-anything-eo](https://github.com/aliaksandr960/segment-anything-eo) repository, and credit for its original version goes to Aliaksandr Hancharenka.

## Features

-   Download map tiles from Tile Map Service (TMS) servers and create GeoTIFF files

-   Segment remote sensing imagery with text prompts
-   Create foreground and background markers interactively
-   Load existing markers from vector datasets
-   Save segmentation results as common vector formats (GeoPackage, Shapefile, GeoJSON)
-   Save input prompts as GeoJSON files
-   Visualize segmentation results on interactive maps
-   Segment objects from timeseries remote sensing imagery
-   REST API for serving segmentation over HTTP (see [API docs](https://samgeo.gishub.org/api))

## QGIS Plugin

SamGeo is also available as a [QGIS plugin](https://github.com/opengeos/qgis-samgeo-plugin). Check out this [short video demo](https://youtu.be/DKKrQKeU3Ik) and [full video tutorial](https://youtu.be/oPZc7BvDsHE) on how to use the plugin.

## Installation

### Install with pixi (Recommended)

For the most reliable installation experience, especially on Windows or when dealing with complex dependencies like PyTorch/CUDA and SAM 3, we recommend using [pixi](https://pixi.prefix.dev/latest). Pixi provides faster and more reliable dependency resolution than conda/mamba and avoids common numpy version conflicts. See the [full pixi installation guide](https://samgeo.gishub.org/installation/#install-with-pixi-recommended) for detailed instructions.

Quick start with pixi:

```bash
# Install pixi (Linux/macOS)
curl -fsSL https://pixi.sh/install.sh | sh

# Or on Windows (PowerShell)
powershell -ExecutionPolicy Bypass -c "irm -useb https://pixi.sh/install.ps1 | iex"

# Create a new pixi project
pixi init geo
cd geo

# Edit pixi.toml with your configuration (see docs for GPU/CPU examples)
# Then install
pixi install

# Start Jupyter Lab
pixi run jupyter lab
```

### Install from PyPI

**segment-geospatial** is available on [PyPI](https://pypi.org/project/segment-geospatial/) and can be installed in several ways so that its dependencies can be controlled more granularly. This reduces package size for CI environments, since not every time all of the models will be used.

Depending on what tools you need to use, you might want to do:

-   `segment-geospatial` or `segment-geospatial[samgeo]`: Installs only the minimum required dependencies to run SAMGeo
-   `segment-geospatial[samgeo2]`: Installs the dependencies to run SAMGeo 2
-   `segment-geospatial[samgeo3]`: Installs the dependencies to run SAMGeo 3
-   `segment-geospatial[fast]`: Installs the dependencies to run Fast SAM
-   `segment-geospatial[hq]`: Installs the dependencies to run HQ-SAM
-   `segment-geospatial[text]`: Installs Grounding DINO to use SAMGeo 1 and 2 with text prompts
-   `segment-geospatial[fer]`: Installs the dependencies to run the feature
    edge reconstruction algorithm
-   `segment-geospatial[api]`: Installs FastAPI and Uvicorn for serving segmentation as a REST API

Additionally, these other two optional imports are defined:

-   `segment-geospatial[all]`: Installs the dependencies to run all of the SAMGeo models
-   `segment-geospatial[extra]`: Installs the dependencies to run all of the SAMGeo models and other utilities to run the examples like Jupyter notebook support, `leafmap`, etc.

Simply running the following should install the dependencies for each use case:

```bash
pip install "segment-geospatial[samgeo3]" # Or any other choice of the above
```

To see more in detail what packages come with each choice, please refer to `pyproject.toml`.

### Install from conda-forge

**segment-geospatial** is also available on [conda-forge](https://anaconda.org/conda-forge/segment-geospatial). If you have
[Anaconda](https://www.anaconda.com/distribution/#download-section) or [Miniconda](https://docs.conda.io/en/latest/miniconda.html) installed on your computer, you can install segment-geospatial using the following commands. It is recommended to create a fresh conda environment for **segment-geospatial**. The following commands will create a new conda environment named `geo` and install **segment-geospatial** and its dependencies:

```bash
conda create -n geo python
conda activate geo
conda install -c conda-forge segment-geospatial
```

If your system has a GPU, but the above commands do not install the GPU version of pytorch, you can force the installation of the GPU version of pytorch using the following command:

```bash
conda install -c conda-forge segment-geospatial "pytorch=*=cuda*"
```

segment-geospatial has some optional dependencies that are not included in the default conda environment. To install these dependencies, run the following command:

```bash
conda install -c conda-forge groundingdino-py segment-anything-fast
```

### Install SAM 3 on Windows

It is a bit tricky to install SAM 3 on Windows. Run the following commands on Windows to install SamGeo:

```bash
conda create -n geo python=3.12
conda activate geo
conda install pytorch torchvision pytorch-cuda=12.1 -c pytorch -c nvidia
pip install "segment-geospatial[samgeo3]"
pip install triton-windows ipykernel jupyterlab
```

## Using SAM with Desktop GIS

-   **QGIS**: Check out the [SamGeo QGIS Plugin](https://github.com/opengeos/qgis-samgeo-plugin).
-   **ArcGIS**: Check out the [Segment Anything Model (SAM) Toolbox for ArcGIS](https://www.arcgis.com/home/item.html?id=9b67b441f29f4ce6810979f5f0667ebe) and the [Resources for Unlocking the Power of Deep Learning Applications Using ArcGIS](https://community.esri.com/t5/education-blog/resources-for-unlocking-the-power-of-deep-learning/ba-p/1293098).

## Computing Resources

The Segment Anything Model is computationally intensive, and a powerful GPU is recommended to process large datasets. It is recommended to have a GPU with at least 8 GB of GPU memory. You can utilize the free GPU resources provided by Google Colab. Alternatively, you can apply for [AWS Cloud Credit for Research](https://aws.amazon.com/government-education/research-and-technical-computing/cloud-credit-for-research), which offers cloud credits to support academic research. If you are in the Greater China region, apply for the AWS Cloud Credit [here](https://aws.amazon.com/cn/events/educate_cloud/research-credits).
