Developing a WebGIS for Geo-Visualization of Cancer

Background: Considering the hygiene facilities and sharing the data of diseases, considerable attempts to promote the public awareness have beenmadeby various media; however, most of the provided information is based onnumerical and verbal statistics, and may not provide suitable understanding for people in regard with the situation of diseases. Objectives: The main aim of this study is to design an interactiveWebGIS system in which people could simply produce and observe their favorite maps of different cancers and environmental parameters. They can use this tools to produce their personalized maps and explore various aspects of the cancer. Materials and Methods: A system has been developed by usingWebGIS for convenience of ordinary users without any knowledge about geospatial information system (GIS) to observe the situation of the diseases and environmental conditions in terms of static and user-produced interactive maps. It has also provided the possibility of spatial comparison of the arbitrary parameters in the framework of bar and pie diagrams. This system has been designed and launched on cancer database of Iran where information of meteorological stations has been embedded as environmental parameters. Results: The innovative idea in this study has received less attention in previous works including possibility of producing webbased Choropleth map so that users could easily select the parameters and algorithms for classification and interactive coloring in the system to produce their personalized maps. Conclusions: Development of WebGIS tools and increased cooperation of people in terms of inserting the spatial labels on the map to report a disease or using their views about reasons of occurring a specific cancer in a specific region may cause turning the process of mono-direction flow of information to users to a bi-directional flow of information. As a result, cancer specialists could use the knowledge of local people and residents of different regions of the country to better analyze the situation of various kinds of cancers.
