GIS

WorldMap

WorldMap is a web-based map collaboration platform hosted at Harvard, which allows anyone to store, organize, visualize, edit, collaborate, and publish geospatial information. Upload your own map layers or use maps others have contributed.
The system attempts to fill the growing gap between powerful desktop-bound mapping applications, and lightweight web map solutions with limited storage capacity.

Sci2 Tool

The Science of Science (Sci2) Tool is a modular toolset supporting temporal, geospatial, topical, and network analysis and visualization of datasets at the micro (individual), meso (local), and macro (global) levels. Users of the tool can:
Access science datasets online or load their own
Perform different types of analysis with the most effective algorithms available
Use different visualizations to interactively explore and understand specific datasets
Share datasets and algorithms across scientific boundaries

GRASS GIS

GRASS GIS is free and open source software used for geospatial data management and analysis, image processing, graphics/maps production, spatial modeling, and visualization. GRASS is currently used in academic and commercial settings around the world, as well as by many governmental agencies and environmental consulting companies.

QGIS

QGIS is a user-friendly Open Source Geographic Information System (GIS) licensed under the GNU General Public License. QGIS is an official project of the Open Source Geospatial Foundation (OSGeo). It runs on Linux, Unix, Mac OSX, Windows and Android and supports numerous vector, raster, and database formats and functionalities.

ArcGIS

ArcGIS is a suite of software that comprises of Desktop GIS, Server GIS, Mobile GIS, and ArcGIS Online. ArcGIS is a platform for building a complete geographic information system (GIS) that lets you easily create, edit, and analyse geographic knowledge on the desktop; publish data, maps, globes and models to a GIS server and/or share them online; and use them on the desktop, on the Web, or in the field.

Features:
View and query maps

Manipulate shapefiles and geodatabases

Data manipulation, editing and analysis

Mobile device enabled

RivEx

RivEX is a GIS tool designed to process vector river networks. It enables the user to undertake a range of tasks associated with the spatial analysis of river networks, including checking the network for topological errors, converting a network to a measured network and generating regular or random sampling points across the network.

ArcExplorer

ArcExplorer is a custom mapping tool that can be used in a web browser. ArcExplorer allows you to perform a range of basic GIS functions such as display, query and retrieve data.
Features:
Display and query a variety of standard data sources including ESRI shapefiles, ArcInfo coverages Images, ArcIMS services

Pan and zoom through multiple layers and identify, locate, and query geographic and attribute data.

Symbolize data based on attributes contained in the data layers to create thematic maps.

Perform basic spatial analysis tasks on the geographic data

ERDAS Imagine

ERDAS Imagine is a suite of geospatial data authoring software. The suite contains a raster graphics editor and remote sensing application that performs advanced remote sensing analysis and spatial modelling to create new information. ERDAS IMAGINE can also visualize results in 2D, 3D, video, and on cartographic quality map compositions. It is primarily designed for geospatial raster data processing and the creation of digital images for mapping use in GIS or CAD software.
Features:
Image Analysis, Remote Sensing

Parallel Batch Processing

Spatial Modeling
