gdb2shp

This Python script extracts shapefiles from an ESRI geodatabase file (.gdb) based on a specified query word. The extracted shapefiles are saved in a directory named extracted_shapefiles.

Prerequisites

Before running the script, you need to have the following installed:

• Python 3.x
• fiona library
• geopandas library

Installation

1. Clone this repository or download the source code.

2. Navigate to the project directory.

3. Create a virtual environment (optional but recommended):

   python3 -m venv venv

4. Activate the virtual environment:

   • On Windows:

     venv\Scripts\activate
     

   • On Unix or macOS:

     source venv/bin/activate

5. Install the required Python packages:

   pip install -r requirements.txt

Usage

1. Download a geodatabase file (.gdb) containing the layers you want to extract shapefiles from.

   Download the sample data from Copernicus.eu.

2. Place and/or extract the geodatabase file in the project directory.

3. Open the gdb2shp.py script and modify the following parameters according to your needs:

   • gdb_dir: Path to the geodatabase directory (e.g., 'EMSN048_UTM32N.gdb').
   • query_word: The word or phrase to search for in the layer names (e.g., 'FLOODRISK01POPRISK').
   • output_dir: Directory name for storing the extracted shapefiles (default: 'extracted_shapefiles').

4. Run the script: python gdb2shp.py

The script will extract all the layers from the geodatabase that match the specified query_word and save them as shapefiles in the output_dir directory.

Makefile

This project includes a Makefile to simplify the installation and usage process. Here are the available commands:

• make venv: Create a virtual environment named venv.
• make install: Install the required Python packages in the virtual environment.
• make run: Run the gdb2shp.py script in the virtual environment.
• make all: Create the virtual environment, install the requirements, and run the script.
• make clean: Clean up the extracted shapefiles, log file, and virtual environment.
• make help: Show the help message with the available commands.
