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.
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.
The tips and tricks here are oriented to BYOD (bring your down data) mapping and OpenStreetMap obliquely. Presentation cartography and basic inventory mapping is the focus here. Spatial analytics is touched upon briefly but is not the main focus. This site makes assumptions that OpenSource GIS mostly means: PostGIS as a spatial data store and Mapnik as a rendering engine, a Mappy CSS styling language like Cascadenik or Carto to setup the layers and their appearance. Interactivity is briefly touched on. Actually embedding the resulting tile assets is briefly touched on.
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.
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.
Tile38 is a in-memory geolocation data store, spatial index, and realtime geofence. It supports a variety of object types including lat/lon points, bounding boxes, XYZ tiles, Geohashes, and GeoJSON. It supports spatial index with search methods such as Nearby, Within, and Intersects, Realtime geofencing through persistent sockets or webhooks and lot more.
With the continuous efforts of adjusting search results to focused target audieces, there's an increasing demand for incorporating geographical location information into the standard search functionality. Spatial Solr Plugin (SSP) is a free, standalone plug-in which enables Geo / Location Based Search, and is built on top of the open source projects Apache Solr and Apache Lucene.
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.
This project is a collection of tools for use with the spatial types that are new to SQL Server 2008. This project does not provide an end-user application, but rather a set of reusable functions which applications can make use of. These functions may include data conversion...
CLR CSharp application to render a set of GIS spatial images directly from SQL Server as rowset data using standard T-SQL language extended for simplicity . C# 3.5 32 or 64 bit extension for SQL server 2008
MsSqlSpatial - Spatial Extensions for Microsoft SQL Server 2005 This project conforms to OGC Simple Features Specification for SQL Revision 1.1 and provides other useful features to power your GIS application.
GeoMesa is an open-source, distributed, spatio-temporal database built on a number of distributed cloud data storage systems, including Accumulo, HBase, Cassandra, and Kafka. Leveraging a highly parallelized indexing strategy, GeoMesa aims to provide as much of the spatial querying and data manipulation to Accumulo as PostGIS does to Postgres.
Geo-Spatial Data Viewer (GSDView) is a lightweight viewer for geo-spatial data and products. It is written in python and Qt4 and uses the GDAL library. GSDView is modular and has a simple plug-in architecture.
This is a component to yield geo spatial services, by implementing OpenGIS specifications which will be accessible through OpenMI interfaces, in order to establish high-level communication with service consumers. A Feature List will be created and updated as the project evolve...
GRASS GIS (https://grass.osgeo.org/) is a Geographic Information System used for geospatial data management and analysis, image processing, graphics/map production, spatial modeling, and visualization. In general: you don't really need write access as you can simply open a pull request to contribute to GRASS GIS. See CONTRIBUTING file for more details.
A handy application for viewing spatial data for use with SQL Server 2008. Its is very difficult to visualise a Spatial shape from a set of points, this application allows you to do that very easily. This is a windows forms application that allows you to draw shapes and obt...
