GeographicLib is a small C++ library for: geodesic and rhumb line calculations; conversions between geographic, UTM, UPS, MGRS, geocentric, and local cartesian coordinates; gravity (e.g., EGM2008) and geomagnetic field (e.g., WMM2020) calculations.
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...
Transform your applications and workflows into powerful agentic systems at global scale.
Gemini Enterprise Agent Platform lets you rapidly build, scale, govern and optimize production-ready agents grounded in your organization's data. The platform enables developers to build custom or pre-built agents for virtually any use case. New customers get $300 in free credits.
Mapyrus is software to plot Geographic Information System data to PostScript, PDF, SVG and web image files. Mapyrus combines a BASIC-like scripting language, reading GIS datasets and running as either a utility program, a Java Servlet, or as a webser
A program for cropping GPX track files. The GUI plots the GPX track (latitude vs longitude) and lets the user remove GPS points from the beginning and end of the track respectively. There is also a built-in Command Line Interface.
Note: No development anymore since I found out that GpsPrune does all the things I was looking for.
GISpatialNet is a Java-based tool for mapping network data (nodes and edges between them) to spatial coordinates; reformatting network and spatial data together; and calculating spatial network measures.
Install by saving to c:\ drive and typing the following in a command line:
java -jar c:\GISpatialNet-0.9b.jar
OSM XML to CSV conversion. POI only, polygons (and polylines, but not recommended) are approximated by centroid. Result is a 3-column table with lon, lat and value (for a particular key to be chosen beforehand).
Paessler: Easy to Use With Enterprise Power. Free Trial
A low-code dashboard makes monitoring intuitive for any admin, while scripting and custom sensors give experts full control.
You shouldn't have to choose between a monitoring tool that's easy to use and one that's powerful enough for a complex environment. PRTG's low-code interface lets any admin build dashboards, set alerts and monitor devices without scripting, while custom sensors and full API access are there when your team needs deeper control. One platform, no compromise. Download a free 30-day trial now.
Spatio Temporal Toolkit is a pure Java "Conceptual" library released under LGPL License that is used to manipulate spatio temporal data-sets. This library is giving powerful boosts to data warehouse projects that envolves spatio-temporal data handling.
OpenDMTP is a protocol/framework that allows communications with small devices (mobile phones, PDA's, and other high-latency/low-bandwidth devices), especially geared towards the transmission of GPS, temperature, and other remote monitoring information.
The goal of the OSM2PostGIS project is to develop an OpenStreetMap data processor that can import any amount of .osm XML data into a PostGIS database, and produce evaluated navigation network topologies to support routing.
Convert a "line string" from a .kml file to a "route" in another .kml file. I started this project to use google maps for routing at home and a very simple GPS-device for following the route while on the road.
A command line java tool that allows creating images of earthquake occurrences plotted on a map over time.
These images can then be used to create a video / animation (with a seperate tool like mencoder)
With OSM Parser it is possible to process OpenStreetMap geodata for various purposes. For example, it can be used to extract streets or other OSM elements for user defined regions to generate a street directory.
A Java application/library that can generate PNG tile overlay images for Google Maps from multiple data sources. Inactive because there are better alternatives: Java - http://geotools.codehaus.org/ PHP - http://www.mapserver.org/
Tool to extract data from a GlobalSat DG-100 GPS data logger and store the data in GPX format. It also can send configuration data to the device, delete stored data and switch the device to GPS-mouse mode.
This project is an open source implementation of axial space syntax software. Space syntax is an analytic urban theory used by researchers to understand elements of the structural aspects of design and how these effect pedestrians and social interaction.
GPSylon is a Java moving map application that is able to display maps like in an atlas and show your position by the use of a gps device. It may track your path, load overlays (e.g. shape files), download maps from expedia servers. - The source code was moved to github!
The project will produce a small standalone Java application which will allow a user to convert ESRI Shapefiles (.shp) to the Google Earth KML format. This will allow ESRI Shapefile points, lines, and polygons to be viewed in Google Earth.
A collection of small utility programs to process geographic information and GPS data. Each program is written in Java and simple enough to be easy to understand. E.g. GTOPO30 to JPG, GLCC20 to JPG, GPX reader.
