I. INTRODUCTION
GIS is a data intensive in nature and it is a mature technology. It has facilitated a large amount of geospatial and non-spatial data. The size of these data with time will grow to be large enough to restrict any single organization to maintain and handle such a massive data. Also GIS applications are severe consume of computational resources such as processing, memory and storage to perform manipulative operations on such huge data. These applications generally include data acquisition and preprocessing from multiple sources which is followed by exhaustive spatial analysis [1]. GIS functions and services are geographically and logically distributed due to the source of data, location of computing facilities and organizations. GI systems are expensive investment (HW, SW, personnel), moreover data acquisition and maintenance which are usually expensive and time consuming [2].
Therefore GIS always develops through governmental authorities and massive organizations which can afford such investment. Many of smaller users in different domains do not have the capability to drive GIS. Cloud computing provides resources as a service. It offers scalable infrastructure and solution to such challenges to host large volumes of data as well as powerful computing resources [1]. With cost reduction are needed and release the upfront expensive cost, Cloud GIS help many businesses [3][4]. The extensive use of GIS especially in mobile apps which becoming increasingly widespread all over the world in different types of fields, can with good opportunity be moved to the Cloud. This trend will provide on-demand services to wider range and a variety of small users.

In response to the two basic types of urban data at the City of Windsor, two GIS web service providers are devised, respectively a vector data service provider and an aerial photo service. Web service providers are computer servers to publish maps. The vector data service provider is an Object-Relational Database (ORD) based server where all GIS vector data is stored and indexed. The aerial photo service provider is a RDMS based server. High resolution aerial photos are stored in RDMS as pyramid images that can accelerate data distribution at different scales. ArcSDE, a middleware that can facilitate data management, data transfer, and data interaction in one RDMS or among RDMSs, is used to help the data communication between the database servers and map servers.

The computation performed on mobile devices is referred to as Mobile Computing [1]. Mobile computing involves mobile communication [2], mobile hardware, and mobile software. Communication is among various adhoc mobile devices in a network which includes certain properties, operations and protocols. Mobile hardware is collection of various mobile devices with in a network. Mobile software includes characteristics and requirements of mobile applications.
Staff training in GIS technology, database operation and maintenance and good data documentation practises is essential.
The information system that interests me in this government department is a new established system called eKadaster (eCadastre). eKadaster is a development project initiated by the government of Malaysia but offered for further development to Precision Portal Sdn. Bhd. on 22nd December 2006. The main objective of eKadaster development is to shorten the time usually take to provide the owner with their land titles from previously 2 years to only 2 months. Other than that, the development of eKadaster is to create National Digital Cadastral Database (NDCDB) covering all Peninsular Malaysia. Moreover, the objective of developing eKadaster is to integrate eKadaster and eTanah (eLand) towards faster and efficient integrated spatial inform...
Cloud Computing is an up and coming strategy that could create millions of jobs while allowing companies to become more profitable. How does Cloud Computing work? The basis of Cloud Computing is having data, software, platforms or networks stored and executed by an outside source and then streaming the output to your electronic device.(McKendrick, J. 2012 march 3) In this paper I will address the following three topics: the history and basis of Cloud Computing, the three main features of Cloud Computing, and the three network types used of Cloud Computing.
Geographers plan new communities, decide where new highways should be placed, and establish evacuation plans. Computerized mapping and data analysis is known as Geographic Information Systems (GIS), a new frontier in geography. Spatial data is gathered on a variety of subjects and input onto a computer. GIS users can create an infinite number of maps by requesting portions of the data to plot.
When they wanted to save photos online instead of on your personal computer, they are able to use “cloud computing” service. Cloud computing means that the transfer of computing data or information over the internet. Not just to keep data in your personal computer, they are able to save the data on internet server to open their data in any computer. In this report we will walk through about what is cloud computing, what kinds of model did cloud computing have, types of cloud computing, benefits of cloud computing, and security.

Spatial Data Infrastructure (SDI) is an information infrastructure providing access and enabling interoperability among spatial information based on standards, policies, regulations and coordination mechanisms (Groot R, 1997). The methods for creating SDI undergone radical changes in the recent years like the shift from the product-led model or data-producer-led model to process-led model or data-user model, etc. However, there are some limitations challenging the SDI growth like the lack of standards to handle linked geospatial data, etc.
Since it emerged, mobile technology has grown into a massive domain. With scores of devices running on various platforms, not every developer takes into consideration everything while developing an application. For instance, there are literally billions of devices running on Android OS. Each coming from a different manufacturer bears a different set of features/characteristics. Not all applications developed take them into account, and function respectively. To cater to that, many developers and software firms are providing with the following services to alleviate the problem.
GIS is an emerging method of data storage and interpretation. GIS is, simply put a database. It is many tables of data organized by one common denominator, location. The data in a GIS system is organized spatially, or by its physical location on the base map. The information that is stored in the database is the location and attributes that exist in that base map, such as streets, highways, water lines, sewers, manholes, properties, and buildings, etc. each of these items don’t just exist in the database, the attributes associated with the item is also stored. A good example of this would be a specific sewer line, from and arbitrary point A to a point B. Ideally, the sewer line would be represented graphically, with a line connecting the two points or something of the like. When one retrieves the information for that line in particular, the attribute data would be shown. This data would include the size of pipe, the pipe material, the upper invert elevation, the downstream invert elevation, the date installed, and any problem history associated with that line. This is the very gist of what a GIS system is.
