Installation

Ensure you have Python 3.x installed. Install dependencies using pip:

pip install py7zr geopandas pandas

Dependencies

• py7zr: For compressing and decompressing files using the .7z format.
• geopandas: For reading, writing GeoPackage files, and performing spatial operations.
• pandas: For handling data structures and data analysis in Python.

Usage

File Retrieval

Retrieve files with a specific extension from a directory and its subdirectories:

from geopackage_utils import get_files

file_list = get_files("/directory/path", file_extension=".gpkg")

Splitting GeoPackage Files

Split a large GeoPackage file into smaller parts:

from geopackage_utils import split_files

split_files("/large/gpkg/file.gpkg", number_of_division=4)

Compression

Compress files in a directory to .7z format:

from geopackage_utils import compress_files

compress_files("/path/to/files")

Decompression

Decompress .7z files into a specified directory:

from geopackage_utils import decompress_files

decompress_files("/path/to/compressed/file.7z", "/output/path")

Merging GeoPackage Files

Merge multiple .gpkg files into a single GeoPackage file:

from geopackage_utils import merge_files

merge_files("/directory/with/gpkg/files", "/output/merged.gpkg")
