JupyterHub is a way to serve Jupyter notebook for multiple users. JupyterHub manages a separate Jupyter environment for each user. It can be used in a class of students, a corporate data science group, or a scientific research group. It is a multi-user Hub that spawns, manages, and proxies multiple instances of the single-user Jupyter notebook server.

DuckLake provides a lightweight one-stop solution for a data lake and catalog, similar to Delta Lake with Unity Catalog and Iceberg with Lakekeeper or Polaris, released under the MIT license. It includes an open table format but it’s also a data lakehouse format, meaning that it also contains a catalog to encode the schema of the data stored. It needs a storage layer (both blob storage and block-based storage work) and a catalog database (any SQL-compatible database works). The data files of DuckLake must be stored in Parquet. Similarly to other data lakehouse technologies, DuckLake does not support constraints, keys, or indexes. Currently, it can be exported into a DuckDB database and vanilla Parquet files. You can also use it for a “multiplayer DuckDB” setup with multiple DuckDB instances reading and writing the same dataset.

OTB is a community driven, extensible and heavily documented open-source project for remote sensing. It can process high resolution optical, multispectral and radar images at the terabyte scale. All of algorithms are accessible from QGIS, Python, the command line or C++. It’s available on Linux, Windows, and macOS (via Docker for ARM Mac computers). Features include:

• Features extraction
• Change detection
• Image manipulation
• Image Segmentation
• Hyperspectral processing
• Data pre-processing
• Data pre-processing
• SAR processing

Supported formats:

• Image formats supported by GDAL (tiff, hrd, img, data providers specifics …)
• Vector formats supported by GDAL/OGR (shapefile, sqlite, postgis …)
• Metadata formats supported by OSSIM and OSSIM plugins (Pléiades and other ADS sensors, DigitalGlobe sensors, NITF)
• Digital Elevation Models supported by OSSIM (SRTM, DTED and generic geotiff DEM)
• KMZ image export

pgModeler is an open-source, cross-platform database modeler designed specifically for PostgreSQL. Aiming to be a reference database design tool in the FOSS ecosystem for PostgreSQL, it offers a robust and feature-rich interface that enables efficient data modeling and rapid code deployment to servers. One of its standout features is reverse engineering, which allows users to generate visual representations of existing databases, making it easier to understand and modify complex structures. Additionally, pgModeler supports the generation of SQL scripts to synchronize a database model with an actual database through a process known as diff. Beyond its core modeling capabilities, the tool includes a minimalist yet functional database server administration module. This module enables users to execute SQL commands, browse databases, and handle data through a simple and intuitive user interface.

LosslessCut is a cross platform FFmpeg GUI for extremely fast and lossless operations on video, audio, subtitles and other related media files. The main feature is lossless trimming and cutting of video and audio files - good for saving space by rough-cutting large video files from a video camera, GoPro, drone, etc. It allows for quickly extracting the good parts from videos and discard many gigabytes of data without doing a slow re-encode and losing quality.

Markdown-based slides creator for developers. Features:

• Diagram support through Mermaid and PlantUML
• Vue component support (with some already built-in like Tweet and Youtube).
• Draggable elements.
• Click and motion animations.
• Clickable table of contents.
• Keyboard shortcuts for navigation.
• Exports to PNG, PDF, PPTX, SPA.

Detects and saves GIS services from browsed websites instead of having to manually dig through network requests to find them. Features:

• Supports WMS, WMTS, WFS, ESRI and tile services.
• Normalizes URLs for use in ArcGIS, QGIS, and other GIS applications.
• Organizes services with custom folders and notes.
• Searches and filters collected services.
• Disables service detection on selected url’s.
• Exports service information for team sharing.

A cross-platform desktop application for JupyterLab.

An easy to use GUI, experimental image optimizer (PNG, JPEG, APNG) designed to be used for web context.

Official Python command-line tool of the Overture Maps Foundation. Overture Maps provides free and open geospatial map data, from many different sources and normalized to a common schema. This tool helps to download Overture data within a region of interest and converts it to a few different file formats.

An ArcGIS Pro toolbox for querying and downloading OSM data.

Anubis weighs the soul of your connection using a sha256 proof-of-work challenge in order to protect upstream resources from scraper bots.

This program is designed to help protect the small internet from the endless storm of requests that flood in from AI companies. Anubis is as lightweight as possible to ensure that everyone can afford to protect the communities closest to them.

Anubis is a bit of a nuclear response. This will result in your website being blocked from smaller scrapers and may inhibit “good bots” like the Internet Archive. You can configure bot policy definitions to explicitly allowlist them and we are working on a curated set of “known good” bots to allow for a compromise between discoverability and uptime.

A small, self-contained cross-platform CLI tool that allows you to just grab the binary and serve some file(s) via HTTP.

An open-source tool for reading OpenStreetMap PBF files using DuckDB.

• Scalable reader for OpenStreetMap ProtoBuffer (pbf) files.
• Is based on top of DuckDB1 with its Spatial2 extension.
• Saves files in the GeoParquet3 file format for easier integration with modern cloud stacks.
• Utilizes multithreading unlike GDAL that works in a single thread only.
• Can filter data based on geometry without the need for ogr2ogr clipping before operation.
• Can filter data based on OSM tags.
• Utilizes caching to reduce repeatable computations.
• Can be used as Python module as well as a beautiful CLI based on Typer4.
