    SAGA GIS
    SAGA - System for Automated Geoscientific Analyses - is a Geographic Information System (GIS) software with immense capabilities for geodata processing and analysis. SAGA is programmed in the object oriented C++ language and supports the implementation of new functions with a very effective Application Programming Interface (API). Functions are organised as modules in framework independent Module Libraries and can be accessed via SAGA’s Graphical User Interface (GUI) or various scripting environments (shell scripts, Python, R, ...). Please provide the following reference in your work if you are using SAGA: Conrad, O., Bechtel, B., Bock, M., Dietrich, H., Fischer, E., Gerlitz, L., Wehberg, J., Wichmann, V., and Boehner, J.

    Baritone

    Baritone

    Google maps for block game

    A Minecraft pathfinder bot. Baritone is the pathfinding system used in Impact since 4.4. How to immediately get started: Type #goto 1000 500 in chat to go to x=1000 z=500. Type #mine diamond_ore to mine diamond ore. Type #stop to stop. For more, read the usage page and/or watch this tutorial playlist. For other versions of Minecraft or more complicated situations or for development, see Installation & setup. Also consider just installing Impact, which comes with Baritone and is easier to install than wrangling with version JSONs and zips. For 1.16.5, click here and see description. Once Baritone is installed, look here for instructions on how to use it. This project is an updated version of MineBot, the original version of the bot for Minecraft 1.8.9, rebuilt for 1.12.2 onwards. Baritone focuses on reliability and particularly performance (it's over 30x faster than MineBot at calculating paths).

    OpenJUMP (The JUMP Pilot Project)
    OpenJUMP is a community driven fork of JUMP the "Java Unified Mapping Platform" GIS software. The original JUMP was developed by Vivid Solutions, released under GPL2 in 2003 and discontinued in 2006. During 2004 already some enthusiastic developers joined together to enhance further the features of JUMP. They launched an independent development branch called OpenJUMP. The name gives credit to the original JUMP development, and at the same time describes the objectives of this project to be fully open to anyone wanting to contribute. These days OpenJUMP is developed and maintained by (some few) volunteers around the globe. If you need functionality or even better want to contribute you are very welcome to contact us at our mailing list.

    Seeker

    Seeker

    Accurately Locate Smartphones using Social Engineering

    Seeker is an open source project that demonstrates how to obtain precise location information from devices using social engineering and web-based techniques. The tool sets up a phishing page that asks for location permissions, allowing GPS and other device data to be shared if the user consents. It can capture latitude, longitude, accuracy, altitude, direction, and even speed, with results displayed in a terminal. The project supports both manual deployment and tunneling services like Ngrok for external access. While primarily intended as an educational resource on security awareness, it highlights the risks of exposing geolocation data online. Its simplicity and effectiveness have made it a popular project in cybersecurity learning circles.

    Open Source Routing Machine

    Open Source Routing Machine

    Open Source Routing Machine - C++ backend

    High-performance routing engine written in C++14 designed to run on OpenStreetMap data. There are several services available via HTTP API, C++ library interface and NodeJs wrapper. Nearest, snaps coordinates to the street network and returns the nearest matches. Route finds the fastest route between coordinates. Table computes the duration or distances of the fastest route between all pairs of supplied coordinates. Match snaps noisy GPS traces to the road network in the most plausible way. Trip solves the Traveling Salesman Problem using a greedy heuristic. Tile generates Mapbox Vector Tiles with internal routing metadata. To quickly try OSRM use our demo server which comes with both the backend and a frontend on top. The easiest and quickest way to setup your own routing engine is to use Docker images we provide. We base our Docker images (backend, frontend) on Debian and make sure they are as lightweight as possible.
