ArcCatalog is a geobase administration application within ESRI's ArcGIS suite whose primary role is to maintain geospatial data and the corresponding metadata. ArcCatalog provides an integrated and unified view of all the data files, databases, and ArcGIS documents, integrating information that exists in many forms, including relational databases, files, ArcGIS documents, and remote GIS web services. In ArcGIS 10, ArcCatalog is folded into ArcMap - the mapping and analysis application.
CatMDEdit is a metadata editor tool that facilitates the documentation of resources, focusing on the description of geographic information resources. The metadata conforms to Dublin Core and ISO 19115 (Geographic Information) standards. Automatic metadata generation for some common geospatial data file formats including Shapefile, DGN, ECW, FICC, GeoTiff, GIF/GFW, JPG/JGW, and PNG/PGW.
ArcGIS Explorer is a geographical information system (GIS) viewer to explore, visualize, and share GIS information. It provides a freely-distributable way to share products produced by ESRI's commercial products.
There are two versions: one for the desktop, the other on-line. The on-line version includes support for time-enabled maps.
ESRI's ArcGIS Desktop software contains ModelBuilder, which is a work flow tool that enables the creation and execution of consistent, repeatable models that are comprised of one or more processing steps. ModelBuilder can be used to ensure the integrity of a particular model or set of analytical processes through modeling, storing, and publishing complex operations and workflows. ModelBuilder workflows can be created and executed on both the desktop and over the web.
ArcGIS Online is a system created by ESRI aimed at providing a common platform to find, share, and organize geographic content and to build GIS applications. The web front end to ArcGIS Online is ArcGIS.com. Through ArcGIS Online you can access maps, applications, and tools published by ESRI and other geographic information systems (GIS) users.
ArcGIS Server is a component of the ESRI suite of commercial software focused on the ability to create, manage, and distribute GIS services over the Web to support desktop, mobile and Web mapping applications.
The user can choose from Basic, Standard, or Advanced editions of ArcGIS Server. Costs vary depending on the level of service required.
ArcMap is the map display and editing workhorse for the ESRI ArcGIS Geographical Information System (GIS) software package. It is most widely used for map creation, but also has broad capabilities for editing and analysis. The "Toolbox" available in ArcMap provides an encyclopedic array of GIS data manipulation and analysis functions for almost any application.
FRAGSTATS is a computer software program designed to work with geospatial data to help the user categorize landscape patterns and metrics, and is useful in identifying areas where land use activities have resulted in fragmentation of the landscape. The current release is version 3.3
The program is currently undergoing another major revamping, which will result in the release of version 4.0 sometime in 2011.
GeoNetwork OpenSource is an open source geospatial data catalog service host, metadata creation and management system, and basic web mapping platform that is in broad use by a number of international organizations in deploying their Spatial Data Infrastructure (SDI).
Google Earth is a flexible mapping and display tool that is installed on a local computer, and accesses on-line data sources provided by Google. These data sources include aerial imagery at a variety of scales and additional data hosted by Google. The user needs to have internet access to view the data provided by Google. Once Google Earth is installed it allows the user to "zoom in" and view satellite and photographic images on any place in the world.
GRASS (Geographic Resources Analysis Support System) is an Open Source Geographic Information System (GIS) that support 2d and 3d raster (gridded) and vector (point/line/polygon) data processing, analysis, and modeling capabilities.
MapWindow GIS is a free desktop geographic information system (GIS) application with an extensible plug-in architecture. It also includes a GIS ActiveX control and a fully C# GIS application programmer’s interface (API) called DotSpatial that can be used by software developers.
The Metadata Enterprise Resource Management Aid (MERMAid) is a tool to develop, validate, manage and publish metadata records via secure internet access. It allows users and data providers to establish unlimited metadata databases to organize their metadata records as they choose (i.e. by program, project, data type, personnel).
The NPS Metadata Tools & Editor is a custom software application developed for the National Park Service (NPS) for authoring and editing NPS metadata. It extends the basic functionality of ESRI's ArcCatalog for managing geospatial metadata and also provides a stand-alone version for creating and manipulating non-spatial metadata outside of ArcCatalog.
Panoply is a cross-platform application which plots geo-gridded arrays from netCDF, HDF and GRIB datasets. It supports the following operations:
Quantum GIS (QGIS) is an open source Geographic Information System (GIS) that implements a large number of geospatial data access, visualization, processing, and analysis functions. It can access vector data stored in a wide variety of formats, including file-based (e.g. ESRI Shape Files, KML, GML), geodatabases (e.g.
SpatiaLite is an extension to the SQLite database that enables it to support spatial data.
SpatiaLite is conformant to OpenGIS specifications. It has the following features:
uDIG (User-friendly Desktop Internet GIS) is an Open Source GIS framework and application for desktop GIS data access, editing, and viewing. uDIG is based upon the Eclipse Rich Client (RCP) Java framework and is extensible through the addition of plugins developed using the RCP framework.
