Abstract:As a result of highly developed information technology, especially after the advent of Web 2.0, people are engaged in contributing any kind of contents (text, photo, video etc.) to the web. We refer to these contents as user-generated content (UGC). UGC applied to location information can be termed user-generated geo-content (UGGC). This phenomenon of creating and sometimes visualizing UGGC as layers on top of base layers from, for example, Google Maps, OpenStreetMap, GeoCommons Maps and Yahoo Maps is known as neogeography and the visualization products can be called neogeography maps.However, neogeography maps have some problems in visualization such as cluttering andusing incorrect colours, shapes and sizes of symbols. In this research, web visualization libraries are used together with cartographic design rules to solve those problems in order to make neogeography maps more easily to interpret and to get some meaningful information fromthe exploration of UGGC. The thesis starts with the terminologies that surround the concepts of neogeographyand cartographic visualization, followed by an overview of uses and users of neogeography maps. Next, the requirements for the exploration of neogeographic point data with the help of maps are discussed. Then, this research gives a description of the design and implementation of a prototype in which web visualization libraries and cartographic design rules are applied. Finally, the evaluation of the prototypeis described. The results show that by applying cartographic design rules, the problems mentioned above may be alleviated. The results also show that with the help of web visualization libraries and the application of cartographic design rules, the prototypein my thesis may have a positive influence on the exploration of neogeographic data.The prototypeprovides a set of maps with some functions that can help users to answer different geographic questions for various purposes. KEYWORDS: Neogeography, Cartographic Design, Web Visualization Libraries, User-Generated Geo-Content (UGGC), Volunteered Geographic Information, Cartography.
