Visualisering är ett kraftfullt sätt att ge människor en förståelse för data med hjälp av mönster. Fördelarna med att kunna visualisera data på rätt kan resultera i förbättrat beslutsfattande, bättre inriktad dataanalys och bättre samarbete och informationsdelning. Visualisering av stora datamängder medför en rad olika utmaningar tack vare dess storlek och struktur. I och med att dagens webbteknologier utvecklats så pass mycket att de kan mäta sig med desktop-applikationer är webbtekniker ett utmärkt hjälpmedel vid visualisering av data för att också göra det mer tillgängligt. I arbetet skapas två applikationer med hjälp av webbteknikerna i MEAN-stacken där datapunkter kommer att skrivas ut på två olika kartor skapade med Leaflet och OpenLayers. Därefter genomförs sedan ett experiment som mäter laddningstider vid utritning av datapunkterna samt vid interaktion med kartapplikationen. Arbetet ska i sin helhet analysera laddningstider hos en interaktiv karta som visualiserar Big Data med hjälp av webbtekniker.

This thesis focuses on development of web-based GPS data management system in a cloud environment. The thesis introduces the most used application interfaces for building custom mapping applications. It offers a comparison of cloud platforms such as Google App Engine and OpenShift Online. It also deals with the design and the implementation of system for OpenShift Online platform. The system focuses on importing tracks from GPX format, managing tracks, viewing tracks on map tiles from Mapy.cz, searching for tracks, creating an elevation profile and various statistics.

The thesis is focused on the problem of the passportization and the visualization of wide computer networks with the usage of geographic information systems. It discusses principals and properties of geographic information systems and spatial databases that are frequently used as data carriers for geographic information systems. The main part of the thesis is dedicated to the passportization of computer networks with focusing on the physical network structure. After the definition of the passport format the thesis continues with the analysis, the proposal, the implementation and the testing of the geographic information system for managing and visualization of the passport in this format. The thesis is ended by a case study that demonstrates the passportization process of an access computer network in the implemented system.

Today there are a big need for a system that delivers overview of all available units for different municipalities and shipping- and security companies due to the increasing requirements for efficiency. The purpose with this graduation thesis is to find out which systems that is suitable to use while developing cost-effective software for positioning and to produce a prototype for such solution. This assignment has been done at the request of PocketMobile Communications AB. PocketMobile is a company that are specialized on delivering modern mobile software solutions and systems to companies with their own vehicle fleet or mobile workers. This master thesis can be split into two separate parts, the theoretic- and the practical part. The theoretic part includes producing a number of functional requirements in cooperation with PocketMobile and comparing the available systems against the function requirements. The practical part deal with the development of a prototype that demonstrates the software recommended. The development tools that best matched the functionality requirements when the selection was made in May 2007 were Map24 and OpenLayers. The system that was selected to use while developing the prototype was Map24, because this product matches all of the requirements and it is also suited for professional usage regarding support, scalability and reliability. Map24 also have some advanced functions like ability to route plan for example. The prototype that has been developed is web based and the graphic design is similar to Google Maps.

The master's thesis is concerned with design and implementation of library extending OpenLayers. For the solution was used JavaScript programming language. Part of this thesis is devoted to description of standards for maintaining and transfering geographic information and to JavaScript map presenting libraries and REST services.
