GIS software and data structures(bilingual)
1、Arc/Info
Arc/Info is a long-lived full functions GIS package that has been ported to the microcomputer, the workstation, and the mainframe. Arc/Info is ud to automate, manipulate, analyze, and display geographic data and incorporates hundreds of sophisticated tools for map automation, data conversion, databa management, map overlay and spatial analysis, interactive display and query, graphic editing, and address geocoding. The software includes a relational databa interface for integration with commercial databa management systems and macro language for developing customized applications called AML (ARC Macro Language). Arc/Info is a generic nonapplication specific approach to geographic information systems, allowing the software to address virtually any geographic application. The software runs both on higher and microcomputers and is available on veral Unix workstations and for Windows NT.
2、ArcView
ArcView is available for Windows, Macintosh, and a variety of Unix platforms. It is a desktop system for storing, modifying, querying, analyzing, and displaying information about geographic space. Support for spatial and tabular queries, “hot links” to other desktop applications and data types, business graphic functions such as charting, bar and pie charts, and map symbolization, desing, and layout capabilities are supported. Gocoding and address matching are also possible. ArcView is also a product of ESRI, who makes Arc/Info. There is compatibility between the two systems, with ArcView being more oriented toward map display than databa management. When the ArcView version II software was introduced, the original ArcView software was placed into the public domain and is available over the Internet.
3、Atlas GIShear过去式
AtlasGIS is available for both DOS and as version 3.0 for Windows. The original vendor has recently sold the software to Clartas, which in turn was purchad in 1996 by ESRI. 炸牛排的做法
This GIS lets you display, edit, and analyze information from a databa or spreadsheet on a map, and can turn statistics and tabular data into graphics for decision-making and prentation purpos. Atlas GIS has a databa management system with spreadsheet-style prentation, map editing, drawing tools, and reporting. Atlas GIS for Windows includes features that give SQL data access and street-level geocoding of address. Interfacing with the Oracle DBMS is also possible.微信公众号视频怎么下载
The graphics allow full-featured geographical analysis and integrated databa connectivity. In recent comparative reviews, three GIS and computer magazines awarded AtlasGIS for Windows the highest rating in value and ea of u. The GUI builds on Windows to allow “point and click” access, a button bar, and a page layout system that displays the map automatically. Several map “style sheets” come with the program. Legends, titles, scale bars and other elements update automatically. A CD ROM of U.S. address allows nationwide geocoding by address matching and supports mapping. A map layer management system let’s you click to change colors, ttings, styles, visibility, and so on. Interface via Windows OLE, allowing cut and paste to other Windows applicati

4、GRASS
网络诊断 The U.S. Army Construction Engineering Rearch Laboratories has developed publicdomain software called the Geographical Resources Analysis Support System (GRASS). Grass is raster bad, was the first Unix GIS software, and has been considerably enhanced by the addition of ur contributions, for example in hydrologic modeling. GRASS is available free over the Internet. Many urs run GRASS on PC’s under the Linux version of UNIX. Since 1985, CERL has relead upgrades and enhancements to GRASS and provided technical ur support. CERL terminated GRASS related work in the spring of 1996. Under formal agreements, CERL now works with commercial vendors both to support GRASS and to integrate its capabilities into commercial system. Existing information on the GRASS World Wide Web sites will be maintained for some time as background.
5、IDRISI
秋夜将晓出篱门迎凉有感其一
The IDRISI software system has been developed, distributed, and supported on a notfor-profit basis by the IDRISI Project, Clark University Graduate School of Geography. To date, there are over 15,000 registered urs of IDRISI software in over 130 countries, making it the most widely ud raster GIS in the world. IDRISI is designed to be easy to u, yet provide professional-level GIS, image processing and spatial statistics analytical capability on both DOS- and Windows-bad personal computers. It is intended to be affordable to all levels of urs and to run on the most basic of common computer platforms. Expensive graphics cards or peripheral devices are not required to make u of the analytical power of the system. The system is designed with an open architecture so that rearchers can integrate their own modules.
