ArcView

ArcView is full-featured geographic information system (GIS) software for visualizing, managing, creating, and analyzing geographic data. Using ArcView, you can understand the geographic context of your data, allowing you to see relationships and identify patterns in new ways.

Key features:

Quality Mapping

• Author maps using simple wizards and an extensive suite of map elements.
• Use predefined map templates that save you time and make it easy to create a consistent style in your maps.
• Create interactive maps from file, database, and online sources.
• Create interactive maps that link nonspatial data to specific locations.
• Create interactive maps that allow you to access a wide variety of digital data.
• Create street-level maps that incorporate GPS locations.
• View CAD data or satellite images.
• Generate reports and charts.
• Save, print, export, or embed completed maps in other documents or applications.

Spatial Analysis

• Analyze spatial data and derive answers from data of a location-dependent nature.
• Visually model and spatially analyze a process or workflow.
• Use a geoprocessing framework that includes ready-to-use analysis tools as well as the ability to build process models, scripts, and complete workflows.

Data Use and Integration

• Create and manage geographic data, tabular data, and metadata.
• Use a wide variety of data types including demographics, facilities, CAD drawings, imagery, Web services, and multimedia.
• Directly read or import more than 70 different formats in ArcView.

Ready-to-Use Datasets

Begin your visualization and analysis right away with the included ESRI Data & Maps Media Kit, which is updated annually and preconfigured to work specifically with ESRI software. The ESRI Data & Maps Media Kit contains more than 24 GB of data including:

• Basemap and thematic MXDs for Canada, Europe, Mexico, the United States, and the world
• Commercial data from Tele Atlas, AND Mapping, DMTI Spatial, WorldSat, EarthSat, EuroGeographics, Michael Bauer Research, World Wildlife Fund, SIGSA, and ESRI
• Ninety-meter Shuttle Radar Topography Mission (SRTM) dataset
• All levels of U.S. Census geography and ZIP Codes
• TIGER 2000-based StreetMap USA data

ArcGIS Online includes optimized, ready-to-use content and capabilities such as 2D maps, 3D globes, and reference layers. ArcGIS Online services are always available on the Web so that users with Internet access can use these services at any time.

GIS Deployment

• View, navigate, and print published ArcGIS maps using ArcReader (.pmf files).
• Deploy your GIS data—share and deliver interactive maps based on dynamic content.
• Offer novices and professionals alike a way to view and query your published maps

Map Viewing and Navigation

• Perform basic map navigation such as zooming and panning and switching between map and page layout view.
• Communicate more efficiently with the ability to graphically mark up maps.
• Utilize ArcWeb Services in ArcReader including route, nearby place, and address finding.

Data Query and Exploration

• Use ArcReader tools such as Find and Identify to explore a variety of geographic data including raster and vector data.
• Use tools such as Identify, Find, Measure, Hyperlink, and Magnifier Window to discover information not available when working with static paper maps.

Map Printing

• Print published map documents and published globe documents including all layer symbology and cartographic map elements on any supported printer.

Unix

Unix operating systems are widely used in both servers and workstations. The Unix environment and the client-server program model were essential elements in the development of the Internet and the reshaping of computing as centered in networks rather than in individual computers.

Both Unix and the C programming language were developed by AT&T and distributed to government and academic institutions, causing both to be ported to a wider variety of machine families than any other operating system. As a result, Unix became synonymous with "open systems".

Unix was designed to be portable, multi-tasking and multi-user in a time-sharing configuration. Unix systems are characterized by various concepts: the use of plain text for storing data; a hierarchical file system; treating devices and certain types of inter-process communication (IPC) as files; and the use of a large number of software tools, small programs that can be strung together through a command line interpreter using pipes, as opposed to using a single monolithic program that includes all of the same functionality. These concepts are known as the Unix philosophy.

Under Unix, the "operating system" consists of many of these utilities along with the master control program, the kernel. The kernel provides services to start and stop programs, handle the file system and other common "low level" tasks that most programs share, and, perhaps most importantly, schedules access to hardware to avoid conflicts if two programs try to access the same resource or device simultaneously. To mediate such access, the kernel was given special rights on the system, leading to the division between user-space and kernel-space.

The microkernel concept was introduced in an effort to reverse the trend towards larger kernels and return to a system in which most tasks were completed by smaller utilities. In an era when a "normal" computer consisted of a hard disk for storage and a data terminal for input and output (I/O), the Unix file model worked quite well as most I/O was "linear". However, modern systems include networking and other new devices. As graphical user interfaces developed, the file model proved inadequate to the task of handling asynchronous events such as those generated by a mouse, and in the 1980s non-blocking I/O and the set of inter-process communication mechanisms was augmented (sockets, shared memory, message queues, semaphores), and functionalities such as network protocols were moved out of the kernel.
