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 Online provides web services that the user can use as data sources in ESRI products such as ArcMap, and for geoprocessing and analysis.
You can also upload and share your own content through ArcGIS Online. ArcGIS Online enables you to control who can access the resources that you upload. You can create one or more user groups, within which you an share resources and collaborate. ESRI provides services that enable you to host your own content in ArcGIS Online, and you can publish your content as part of a community basemap that users can access freely through ArcGIS Online as a map service. ArcGIS Online also includes tools for creating online maps and for viewing maps created by others.Additional Information: Tags: data storage,geospatial,GIS,repository,social networking Contributor: JH, RL Cost: Free
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. Within ModelBuilder, a model consists of processes and the connections between them. Parameters can be defined that will be filled into a pop-up form at runtime. Most of the geoprocessing tools available within ArcGIS can be used as processes within ModelBuilder as part of a workflow. Model workflows can also be rerun with different data or inputs for evaluating scenarios. ModelBuilder is included in all license levels of ArcGIS Desktop. Models created can also be exported as scripts in Python and other programming languages.Additional Information:
ModelBuilder is a part of the ArcGIS software package. You must have an ArcGIS license to use ModelBuilder.
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.Additional Information:
There is a free SDK available for download.
CA ERwin Data Modeler (or ERwin for short) is a data modeling and database design tool that is used to create conceptual, logical, and physical data models. ERwin can create the actual database from the physical model, and create different physical implementations from a single logical model. ERwin can also reverse-engineer existing databases into a data model diagram. ERwin works with many database management systems (DBMS). Outputs from the tool include entity-relationship (ER) diagrams and standard or custom reports on all objects in the design (tables, fields, relationships).
While users are charged for the full version of ERwin, there is a free "Community Edition" available for students and others new to modeling to try the functionality of the software on a small dataset. The Community Edition has a limit on the number of objects (25) that can be created in the data model.Additional Information: Tags: data model,database,models Contributor: ST, EL Cost: Cost-basis
Erdas Imagine is an image processing software package that allows users to process both geospatial and other imagery as well as vector data. Erdas can also handle hyperspectral imagery and LiDAR from various sensors. Erdas also offers a 3D viewing module (VirtualGIS) and a vector module for modeling. The native programming language is EML (Erdas Macro Language). Erdas is integrated within other GIS and remote sensing applications and the storage format for the imagery can be read in many other applications (*.img files). Leica Geosystems also purchased ER Mapper to add to their mapping software. Imagine is tightly woven into the GIS fabric more than other image processing software packages and that is the advantage of this package.Additional Information: Tags: Contributor: Cost: Cost-basis
ENVI is software for processing and analyzing geospatial imagery. ENVI handles hyperspectral, LiDAR, and other remotely sensed data sets easily with both wizard based approaches and allowing users to program operations. The main benefit of using ENVI is for the analysis and visualization of spectral and hyperpsectral data. Currently, ENVI is developing comprehensive GIS tools to integrate within the ESRI software family. ENVI has internal workflows and allows users to customize procedures with their IDL programming language.Additional Information: Tags: Contributor: Cost: Cost-basis
Enterprise Architect is a modeling, visualization, and design platform. It can be used in software design, data modeling, and database design and is useful for creating and analyzing UML diagrams. It has a built-in data modeling profile that extends UML to provide a mapping from the database concepts of tables and relationships onto the UML concepts of classes and associations. Enterprise Architect supports modeling of database schema for many popular relational database management systems (RDBMS). It can be used to capture and trace formal requirements for designing, building, and deploying software and databases. Enterprise Architect also supports generation and reverse engineering of source code for a variety of programming languages. It has a built-in source code editor that lets you navigate from a visual model to source code in the same interface.Additional Information: Tags: database,models,XML Contributor: JH, ST Cost: Cost-basis
EndNote is software for managing bibliographic citations. It integrates with Web of Science to allow for quick entry of citations. EndNote Web is also available to licensed users, which allows them to use EndNote when they are away from their own computer. Citations can be output in a large number of citation styles. Plugins exist for word processors and web browsers to enable quick citation.Additional Information: Tags: bibliography,citation,metadata,metadata editor Contributor: PW, RL Cost: Cost-basis
NASA's Earth Observing System (EOS) Clearinghouse (ECHO) is a metadata registry and order broker that allows query and access to data from a large number of repositories, primarily NASA repositories, though any repository can request to have their metadata included in the ECHO database. ECHO stores metadata from a variety of science disciplines and domains, including Climate Variability and Change, Carbon Cycle and Ecosystems, Earth Surface and Interior, Atmospheric Composition, Weather, and Water and Energy Cycle. The primary way for interactively searching and ordering data within ECHO is through the WIST client, though a variety of web service API's are available for those who wish to include WISTFUL data within their own clients.Additional Information: Tags: Contributor: RD, MS Cost: Free
Drupal is a open source CMS (Content Management System) for websites. Drupal enables webmasters to create professional websites with a minimal amount of specialized coding or systems support.
Drupal's architecture consists of a core platform that can be customized with user-supplied profiles, modules, themes, and languages. Drupal separates content from presentation, and -- when combined with Drupal's "codeless" module building -- allows high flexibility, while maintaining relative simplicity. This yields high productivity in designing and deploying a wide variety of websites, thus driving Drupal's wide user base.
Code (when required) is written in PHP and the content is stored in a MySQL database. In general, Drupal is fairly approachable for someone with basic programming and web authoring skills. It is a generally low-overhead solution for web page construction that enables multiple contributors. Many university departments support Drupal for their investigators and will help with Drupal administration.Additional Information: Tags: collaboration,content management system,metadata,web services Contributor: DG, MO Cost: Free
