UTREDNING SAMT UTVECKLING AV ETT PLATTFORMSOBEROENDE GEOGRAFISKT INFORMATIONSSYSTEM

Sammanfattning: This thesis have been performed at Sweco Position in Jönköping. The work was split into two, where one part included an investigation regarding the possibility of developing a cross-platform GIS (geographic information system) with HTML5 and CSS3. A prototype would also be developed within this part. The second part included development of a cross-platform GIS for a client to Sweco Position. The client operates in the forest sector and had already an existing solution, with many problems. The client required an application with delimited functionality and which was not bound to a specific hardware. As the client users often were located in areas with limited Internet access, one additional requirement was that there would be some offline support. The students handle subjects within development of GIS, for example map projections, map services and mapping libraries. The application came to be developed in HTML5 and ASP.net. The mapping library that was used, was Leaflet 0.3.1. The result of this thesis is a cross-platform GIS with offline support. Examples of functionality included is to log positions manually, execute an automatic log function and support for managing which layers and logs that should be visible in the interface.
