The control signals CE, CS, and R/C control the operation of the converter. The state of R/C when CE and CS are both asserted determines whether a data read (R/C = 1) or a convert (R/C = 0) is in progress. The register control inputs AO and 12/8 control conversion length and data format. The AO line is usually tied to the least significant bit of the address bus. If a conversion is started with AO low, a full 12-bit conversion cycle
is initiated.

Abstract
Internet geographic information system WebGIS is the Internet technology applies in the GIS development product, is one kind based on Internet OpenGIS. GIS can expand through the WWW function, truly becomes the tool which one kind of populace use. From the WWW random node, the Internet user may glance over in the WebGIS stand the spatial data, the manufacture topic chart, as well as carries on each kind of spatial retrieval and the spatial analysis, thus causes GIS to enter everyone. Is called generally Internet's in GIS WWW-GIS or WebGIS, Chinese named World Wide Web GIS. WebGIS is by the WWW Web page took the GIS software the user interface, Internet and the GIS technology unifies in together, can carry on GIS which each kind operates alternately, it is one kind of big social level GIS. The Web page use hypermedia technology and the hypertext link language, causes to a WWW operation richer flexibility and interesting. Will take GIS by Web the user interface, as soon as will change formerly the GIS software user interface stereotypical stiff face, favored the GIS popularity.
The this article primary coverage includes:
1. WebGIS research and development condition as well as based on WebGIS campus geographic information system vital significance;
2. WebGIS outline;
3. Based on WebGIS campus geographic information system system design;
4. Based on WebGIS campus geographic information system system realization;
5. Application example.
The practice indicated that, this system has the nimble data organization way, the user interface friendly as well as the quite perfect function, has satisfied user's request to a certain extent.
Key word: WebGIS World Wide Web GIS geographic information system
