Geospatial Intelligence Workshop

This repository contains code and data for a geospatial intelligence workshop covering unsupervised land cover classification with Sentinel-2 data.

Setting up the Environment

Prerequisites

Make sure you have the following installed on your local machine:

Docker: Install Docker on your machine by following the instructions provided here.

Running the Web Application

1. Clone the repository:

   git clone https://github.com/Romanian-Space-Initiative/Geospatial-Intelligence-Workshop.git
   cd Geospatial-Intelligence-Workshop/webapp

2. Build the Docker container:

   docker-compose build

3. Run the Docker container:

   docker-compose up

4. Open your web browser and go to http://localhost:5001 to access the web application.

Running the Unsupervised Classification Workflow

For the first part of the workshop, we will use a Google Colab notebook. Follow these steps:

1. Open a new notebook using your Google account(and if you do not have one, please create it): Google Colab.

2. Download the following files locally(This is already done if you cloned the repository on you computer):

   • All .tif images from the "S2_data" folder
   • All files from the "ValidationData" folder
   • The notebook "Sentinel2_unsupervised_classification.ipynb"

3. In Google Colab, click on File -> Upload notebook and upload the "Sentinel2_unsupervised_classification.ipynb" notebook.

4. In the Files tab on the left, create a new folder named "S2_data." Upload the .tif images to this folder using the three dots menu.

5. Upload each file from the "ValidationData" folder separately.

   Note: Allow all files to fully upload before proceeding.

6. Run the cells in the notebook to perform the unsupervised land cover classification with Sentinel-2 data.
