pyGISS - :satellite: A lightweight GIS Software in less than 100 lines of code
A Geographic Information System (GIS) software is a software designed to import, analyze and visualize geographic data. PyGISS is a lightweight GIS software implemented both in tkinter and pyQt. Users can display maps using any type of projection and create objects either by importing an Excel file containing GPS coordinates, or with a Drag & Drop system. The standard version implements PyGISS in less than 100 lines of code.
Geographic Resources Analysis Support System, commonly referred to as GRASS GIS, is a Geographic Information System (GIS) used for data management, image processing, graphics production, spatial modelling, and visualization of many types of data. GRASS supports raster and vector data in two and three dimensions. The vector data model is topological, meaning that areas are defined by boundaries and centroids; boundaries cannot overlap within a single layer.
Whitebox GAT is an open-source geographical information system (GIS) and remote sensing package. The Whitebox GAT project began in 2009 and was conceived as a replacement for the Terrain Analysis System (TAS). Whitebox GAT is intended to provide a platform for advanced geospatial data analysis with applications in both environmental research and the geomatics industry more broadly.
QGIS is an Open Source Geographic Information System. QGIS aims to be an easy to use GIS, providing common functions and features. The initial goal was to provide a GIS data viewer. QGIS has reached that point in its evolution and is being used by many for their daily GIS data viewing and editing needs. QGIS supports a number of raster and vector data formats, with new support easily added using the plugin architecture.
SAGA is a free geographic information system (GIS), with a special 'Application Programming Interface' (API) for geographic data processing. This API makes it easy to implement new algorithms. The SAGA API supports grid data, vector data, and tables. It has been designed for an easy and effective implementation of spatial algorithms.
MapWindow 6 Alpha Desktop GIS is a lightweight open source geographic information system (GIS) built using C# and the open source DotSpatial library (see DotSpatial on CodePlex.com). MapWindow 6 Alpha Desktop GIS is intended to be a complete implementation of DotSpatial and su...
HydroDesktop is a free and open source GIS enabled desktop application that helps you search for, download, visualize, and analyze hydrologic and climate data registered with the CUAHSI Hydrologic Information System.
This tutorial is an introduction to visualising and analysing spatial data in R based on the sp class system. For a guide to the more recent sf package check out Chapter 2 of the in-development book Geocomputation with R, the source code of which can be found at github.com/Robinlovelace/geocompr. Although sf supersedes sp in many ways, there is still merit in learning the content in this tutorial, which teaches principles that will be useful regardless of software. Specifically this tutorial focusses on map-making with R's 'base' graphics and various dedicated map-making packages for R including tmap and leaflet. It aims to teach the basics of using R as a fast, user-friendly and extremely powerful command-line Geographic Information System (GIS).
A .NET 2.0 library that performs coordinate conversions between various geodetic coordinate systems for use in fx. Geographic Information Systems (GIS) or GPS applications. Support include: - Datum transformations - Geographic, Geocentric, and Projected coordinate systems - Comp
NOTE - All project resources are now hosted at http://qgis.org. Quantum GIS (QGIS) is a Geographic Information System (GIS). QGIS supports common vector and raster formats, including Shapefiles, PostGIS, GRASS, GeoTiff, TIFF, JPG, and many more.
PostGIS is a spatial database extender for PostgreSQL object-relational database. It adds support for geographic objects allowing location queries to be run in SQL. PostGIS adds extra types (geometry, geography, raster and others) to the PostgreSQL database. It also adds functions, operators, and index enhancements that apply to these spatial types.
uDig is an open source desktop application framework, built with Eclipse Rich Client (RCP) technology. The goal of uDig is to provide a complete Java solution for desktop GIS data access, editing, and viewing. It supports GeoRSS, geospatial web services and provides the framework on which complex analytical capabilities can be built, and gradually subsuming those capabilities into the main application.
Retrieve, construct, analyze, and visualize street networks from OpenStreetMap: full overview. You can just as easily download and work with building footprints, elevation data, street bearings/orientations, and network routing.
The GIS Tools for Hadoop are a collection of GIS tools that leverage the Spatial Framework for Hadoop for spatial analysis of big data. The tools make use of the Geoprocessing Tools for Hadoop toolbox, to provide access to the Hadoop system from the ArcGIS Geoprocessing environment. Start out by navigating to samples and following the instructions provided with each sample.There are also tutorials for using the GP tools and aggregation methods.
GIS vector-based spatial data overlay processing is much more complex than raster data processing. The GIS data ?les can be huge and their overlay processing is computationally intensive. Meager amount of work has been done on processing large volume of vector geospatial data ...
Vector Raster Geographic Information Synthesis. Incorporates Vector: Vector processing, Image processing, Digital Elevation Model DEM processing. These data can be combined to be viewed in 3D. Multitude of system organization aids.
The Open Geospatial Library aims to provide an open source GIS library for the .NET framework. The library will implement various Open Geospatial Consortium (OGC) and ISO specifications. Currently, we are in the process of porting and enhancing the JTS Topology Suite library,...
