Many of these devices suffer from serious constraints in three main areas: processor speed, memory space and screen size. This paper presents a GIS application, called "MacaoMap", that is intended for heavily resource-co nstrained handheld devices. MacaoMap is a tourism-oriented map application of t he Macao territory for PalmOS and Pocket PC personal digital assistants. It was designed to perform satisfactorily on devices with as little as 16 MHz processor speed, and requires only 500 KB available memory for the GIS application and al l GIS data. Memory requirements are kept low through a specially designed data f ormat. The main challenge of satisfactory map drawing speed is addressed through a variety of techniques that were developed for this application. The paper des cribes the application’s data format, outlines the map drawing techniques, and points out the areas for future development.展开更多

And we develop a set of mobile GIS basic software platform in the Android platform, and tested in the mainstream smart mobile phone with Android operating system, test results show that the software platform can run smoothly. Other users can development a variety of mobile GIS to call the platform through an application service interface.展开更多

In South Africa, in order toallocate subsidized housing to beneficiaries of an informal settlement, beneficiary administration needs to determine the number of people who qualify for subsidized houses. Withoutgeo-spatial data-based technical verification, conventional methods of occupancy audits areoften cumbersome, are unreliable, and do not promote smart and evidence-based decisionmaking. Accordingly, the aim of this study is to propose and develop an Oracle-based mobileGIS tool to conduct an occupancy audit for Ulana, an informal settlement in EkurhuleniMunicipality in South Africa. Android-based tablets were used to collect the geographicand socio-economic attributes of the informal dwelling units (DU). Spatial analysis (inArcGIS software and geo-spatial modeling environment) and statistical analysis were conducted to produce the occupancy audit. The results indicated that the use of mobile GISprovides up-to-date, accurate, comprehensive, and real-time data so as to facilitate thedevelopment of smart and integrated human settlements. The results of this audit alsoindicated that only 57% of the households residing in Ulana could potentially benefit fromreceiving a subsidized house. Accordingly, the occupancy audit enables planners to planappropriate upgrading and housing development strategies for informal settlement. Thisstudy demonstrates that successful planning of housing delivery for post independentintegrated neighborhoods is not a mere political rhetoric but is viable when it is based onreasonable geo-spatial techniques and information. The use of mobile GIS therefore needs tobe extended to other informal settlement upgrading projects in South Africa as well as othercities in the global south. However, proper professional training is required to ensure thesuccessful usage of smart mobile GIS tools.展开更多

This paper analyzes the meaning of mobility and the change for geographic information service model, it describes the differences and correlation between M GIS and traditional GIS. It sets a technical framework of geographic information services according to mobile context and provides a case study.展开更多
