This is one of the questions that many ask themselves, after the ESRI convention we came with all that number of very nice catalogs but that on several occasions cause confusion about what I occupy in what I want to do. The purpose of this review is to provide a synthesis of what ESRI products are, their functionality and price for decision-making by users who intend to purchase them.
In this section we will see the base products, in a later one we will analyze the most common extensions, although ESRI still sells 3x versions (which are still in use, we will focus on the most recent versions (9.2)
ArcGIS is an integrated collection of ESRI products designed to build, maintain, and leverage a geographic information system (GIS), including scalable desktop, server, web services, and mobile capabilities. It is understood that companies buy several of these products based on what they need, the ArcGIS base products are as follows:
This is a set of tools for desktop use, generally to build data, edit, analyze and generate products for printing or publishing.
ArcGIS Desktop it is equivalent to AutoCAD in the industry of AutoDesk or Microstation in Bentley; It is useful for common jobs in the GIS area, if you want to do more specialized things there are other extensions or applications, this is called
Scalability ranging from ArcReader, and extending to ArcView, ArcEditor, and ArcInfo. (Although as our friend Xurxo says, it is not scalable because the application is the same with a different interface) Each of these scales implies progressive capabilities that are complemented by other extensions.
ArcGIS Engine is a library of desktop development components with which programmers can build components with custom functionality. Using ArcGIS Engine, developers can extend functionality into existing applications, or build new applications for their own organizations, or resell to other users.
ArcGIS Server, ArcIMS and ArcSDE are used to create and operate server-based applications, which share GIS functionalities either within an intranet or served to the public via the Internet. ArcGIS Server is a central application used to build GIS applications from the server side and that are used by users within a company and interfaces from the web. ArcIMS It is a map service for the publication of data, maps or metadata on the web using standard Internet protocols. ArcSDE Is an advanced data server to access geographic information management systems in relational databases. (Before we made a Comparison of these IMS services)
ArcPad Accompanied by a wireless mobile device, it is widely used to consult or collect data and information in the field, especially applied to GPS devices or PDAs. ArcGIS Desktop and ArcGIS Engine running on a laptop or tablet are used to perform tasks that require data collection, analysis, and decision making.
All these programs use the concept of geodatabase, which is the
Standard of geographic information bases used by ArcGIS (A very typical ESRI format, with the limitation of its constant changes between versions). The geodatabase is used to represent real-world land objects in ArcGIS and store them in a database. The geodatabase implements business logic as a set of tools to access and manage geographic information data.
ArcView is ESRI's basic system for viewing, managing, creating, and analyzing geographic data. Using ArcView you can understand the context of geographic data, allowing you to see the relationships between layers and identify patterns of behavior. ArcView helps many organizations to make decisions quickly.
ArcView is the world's most popular desktop geographic data management system (GIS) because it provides an easy way to use the data. With a large amount of symbology and geographic capabilities you can easily create high quality maps. ArcView makes data management, basic editing, and arduous tasks supplemented by various people in an organization. Virtually any geographic data provider can make their information available in ArcView's supported formats. And the fact that data can be integrated from various sources, projects can be initiated appropriately with data that is available locally or on the Internet. The price of an ArcView license goes for $ 1,500 for a PC and $ 3,000 for a floating license. There are also some special prices For municipalities.
ArcView simplifies complex analysis and data management tasks by allowing tasks to be viewed as visual models within a logical workflow. ArcView is easy for non-specialist users to use, and advanced users will be able to take advantage of its specialized tools for mapping, data integration, and spatial analysis. Developers can customize ArcView using languages commonly used in the programming industry. ArcView is an ideal tool for desktop work, among its special features we can mention:
- Geographic data management for better decision making
- View and analyze spatial data in new ways
- Build new collections of geographic data quickly and easily
- Create maps for high-quality publishing or distribution
- Manage files, databases and Internet data from a single application
- Customize the interfaces according to the tasks of the users that need to be integrated into the work.
ArcEditor is a complete system for GIS applications for editing and manipulating geographic data. ArcEditor is part of the ArcGIS package and includes all the functionalities of ArcView and additionally contains some tools to edit information.
ArcEditor has the advantage of supporting both one and multiple users working in collaborative processes. A set of tools expand your capabilities for cleaning and feeding data, as well as handling complex topologies and maintaining versioned data. The price of an ArcEditor license is $ 7,000.
Some of the functionalities that can be implemented with ArcEditor are:
- Create and edit GIS attributes with “CAD-style” vector editing tools
- Build geographic databases rich in intelligent features
- Complex models, multiuser workflows
- Construct and maintain spatial integrity including relationships of topologies between geographic attributes
- Manage and explore geometries in the form of network systems
- Increase productivity in editing
- Manage a multi-user design environment with data with versioned modifications
- Maintain spatial integrity between thematic layers and force a systems customization logic oriented to alert processes in the maintenance and updating of data.
- Operation with data disconnected, editing in the field and later synchronization.
ArcInfo is considered the most complete geographic information management system (GIS) available from the ESRI line. It includes all the functionality of ArcView and ArcEditor, additionally it also includes advanced geoprocessing components and additional data conversion capabilities. Professional GIS users use ArcInfo for data construction, modeling, analysis and map display both on screen and in print or distribution end products. The price of an ArcInfo license is $ 9,000.
ArcInfo, with its functionalities within the same package (out of box) has the capabilities to create and manage a complex GIS system. This functionality is accessible under an interface considered "easy to use", or at least that can be recognized by its widespread use that has reduced the learning curve as a result of its popularity. These functionalities are customizable and extensible through models, scripting and custom applications.
- Build complex geoprocessing models for related entities, data analysis and information integration.
- Implement vector overlays, proximity and static analysis.
- Generate events along linear attributes and event overlap with attributes of various layers.
- Convert data to and from various formats.
- Build complex data and analysis, abstraction, and scripting models to use GIS processes.
- Post cartographic maps using out-of-the-box deployments, design, print and apply data management techniques.
...update… The initial versions of ArcInfo were based on boundary centroid coverage, similar to Microstation Geographics logic and these were called coverages (an object could share different attributes). Versions 9.2 no longer have that logic, but adapted the shape file concept further.
...update... Although ESRI has the most popular tools on the market, prices are usually a limitation for many to opt for the eye patch :), although it is worth mentioning that being a large company maintains the stability of a technological trend (although it is not the best solution), however that necessary evil ensures a decrease in the learning curve ... aunqeu There are other options.
In the next post we will be analyzing the main Extensions of ArcGIS.
