The aim of this thesis is to design and implement a mobile application for a user-friendly visualization of geodata in augmented reality. The application is created in Java using Android SDK and Android Studio IDE. Geodata represented as geographic points is imported into the application via KML format. The data is shown over a native camera preview as a virtual overlay with use of sensors and GPS. Some of the viewing parameters are adjustable via GUI.

Effective management and sharing of geodata is one of the priorities of governments and companies all around the world. Nowadays spatial data are published without any standardized methodics and unified metadata. This situation leads to multiple storing of such geodata and consequential high expenses and inconsistency. There is usually a problem even find an appropriate mapserver with the required data. Obviously there is a problem: How to access geodata more effectively. We are searching in emails, discussions, documents around the web, even in pictures. But currently there is no searching engine for geodata which could be compared with well known searching services such as Google, Yahoo!, etc. Therefore I focused on this issue. The first part of this work briefly presents standards used for publishing geodata. A review of methods used for geodata and metadata aggregation follows. Based on this review, a method for development of an engine for geodata search is presented. Last part describes principles of experimental implementation and achieved results.

The aim of my thesis was describe a clear form to present the possibilities of facilities for the collection of GIS data for the possible use in land consolidation. My purpose was to accurately determine what the potential cost of purchase and processing of data and how accurately we are able to process this data. Next I have dealt with quality data that we can get from organizations that work with data. I also dealt with the design of land consolidation method using a digital terrain model (DTM). This method could bring a lot of innovation in solving problems in land consolidation in the future

Öppna geodata är idag (2016) ett ofta debatterat ämne och många aktörer i samhället får mer och mer intresse för frågan, i synnerhet i offentlig sektor. Även på riksnivå har politiker börjat verka för öppna geodata, där riksdagen nyligen har beslutat kring ett flertal motioner i frågan. Regeringen har dessutom uppdragit om studier om öppna geodata. Sverige ligger efter övriga nordiska länder, men även andra länder har kommit längre i utvecklingen mot öppna geodata. Idag arbetas mycket på området och myndigheten med ansvar för geodata i Sverige, Lantmäteriet, har börjat öppna datamängder, och fortsätter verka för vidare öppnanden. Detta kandidatexamensarbete har genomförts vid Kungliga Tekniska Högskolan, KTH, i samarbete med Agima Management AB. Arbetet syftar till att studera vilka möjligheter öppna geodata medför och vilka utmaningar en organisation ställs inför när organisationen ska öppna geodata. Genom en litteraturstudie kring olika åsikter, främst ifrån offentlig sektor, och intervjuer med personer verksamma inom geodataområdet sammanfattas dessa möjligheter och utmaningar med öppna geodata. Resultaten av arbetet visar att de främsta möjligheterna med öppna geodata är näringslivsutveckling och innovationskraft samt effektiviseringspotential i offentlig sektor. Vidare leder detta till positiva samhällsekonomiska effekter. De utmaningar en offentlig organisation ställs inför vid ett öppnande av geodata är framför allt finansieringen av geodata. Detta eftersom geodata idag delvis finansieras av avgifter från användare. I förlängningen finns utmaningar med att upprätthålla en hög kvalitet på geodata om geodata till exempel skulle skattefinansieras. Detta blir därför en ständig fråga för tjänstemän och politiker. Slutsatsen är att eftersom möjligheterna övervinner många av utmaningarna, då dessa inte är direkta nackdelar utan något som behöver lösas på ett annat sätt än idag, kan öppna geodata antas bli vanligare i Sverige på sikt. En av anledningarna till den relativt låga hastighet Sverige håller på området verkar vara att tjänstemän och politiker inte är på samma nivå i frågan idag. / Open geodata is today (2016) a highly debated topic and the interest for the matter is increasing, especially for the public sector. In the parliament, politicians have started to work for open geodata, where the parliament recently decided about several motions on the matter. Recently, there have also been assignments from the government about studying open geodata impacts. Sweden is behind the other Nordic countries and several other countries have evolved further towards open geodata as well. Today there is a lot of work on open geodata questions and the Swedish mapping, cadastral and land registration authority, Lantmäteriet, has started to open some of its data, and is aiming towards opening more. This Bachelor of Science thesis has been conducted at KTH Royal Institute of Technology, in cooperation with Agima Management AB. The study aims towards describing the opportunities that open geodata brings, and the challenges that an organization faces when opening data. These opportunities and challenges are summarized through a literature review of different opinions, mostly from the public sector, and personal interviews with persons in the geodata field. The results show that the foremost opportunities with open geodata is in developing business and innovation as well as efficiency improvements in the public sector which leads to economic gains. The challenges a public organization faces when trying to open geodata is mainly financial. The financial issues come from the current model where fees from users are financing the operations. In extension, there will also be challenges with sustaining a high quality of geodata, which will be a constant question for officials and politicians if geodata, for example is financed by taxes. The conclusion is that since the opportunities overcome the challenges, as many of the challenges are not direct drawbacks, but rather something that has to be solved in a different way than it is today, open geodata may become more normal in Sweden eventually. One of the reasons for Sweden’s relatively low speed in the area seems to be that public officials and politicians are at different levels in the matter today.

The diploma thesis deals with the creation of a geographical information system for the city. The theoretical part deals mainly with issues of geographic data, their models with structures and structures. Database systems are geodatabase oriented. The practical part deals with particular projects of GIS creation for the town of Detva using the ArcInfo software. Part of the project is spatial analysis, which aims to find a suitable location for the location of photovoltaic power plants. The resulting project will be used for Detva's needs.

This master thesis deals with the design and implementation of an application used for spatial data processing. The first part provides an overview of different augmented reality projects focused on manipulation with spatial data. It also contains review of computer vision libraries. In the methodology, description of all project components is provided. The following part describes in detail the design and implementation of mentioned application for spatial data processing. The proposed implementation is verified on scenario of spatial turn-based game
