Digital maps on the web, and accessibility

Abstract

The necessity of location information and knowing where you are at any time, have brought foreword the Global Positioning System (GPS) technology. Graphic Information System (GIS) have since the 1980s grown to be used in all kinds of relations. Combining both GPS and GIS solutions have been used for some time now and we have seen it used for navigation at sea. Using the wireless net also mobile phones and Personal Data Assistants can take advantage of this technology. This assignment enlightens different GIS solutions and how any user can use them. The report is a result of the investigation and will be used as information on new technology for the you-too consortium. At first I compiled an overview of map solutions on the Internet today. The overview describes possibilities and restrictions the different solutions give. The GIS solutions have many different qualities, but what’s most important for the you-too project is user friendliness, costs and if they interact with databases. The prototype was altered during the project as some of the intended problem already was solved. We finally agreed to make a demonstration of how coordinates from a map can relate with GPS coordinates. Based on accessibility information we use GIS solutions to provide this information. This solution is for the time being only web based, but this can easily be implemented on a Personal Data Assistant. To relate this coordinates I had to connect two databases, one with the location information, and one with facility information.
