He loves to learn, teach, and occasionally blogs on his website at http://vasir.net/. As a professional web developer of five years, Erik specializes in Python and JavaScript, using open source software whenever possible. When he's not developing web applications, he's often developing or designing video games. He works at FREAC (Florida Resources and Environmental Analysis Center), a great place with great people that does all kinds of GIS and web development work. I'd like to thank the developers of OpenLayers, who continually do a fantastic job of developing the best web-mapping framework. I'd like to also thank my friends and mentors Ian Johnson and David Arthur for giving me the confidence and support I needed to get into web development. I'd like to thank Georgianna Strode and Stephen Hodge for their guidance, advice, and providing me with the opportunity to become a better web developer. I could not have written this book without the help of the great team at Packt; I hope every author can be as lucky as me to have such an excellent group of people to work with. I'd like to thank my parents for their never ending support. Lastly, I'd like to thank my love, Alisen, for her understanding and taking the time to help me make sure that the book is as easy to read as possible. About the Reviewers Xurxo Méndez Pérez was born in 1983 in Ourense, a little town in the south of Galicia, Spain. He lived there until he started the study for a degree in IT in the University of A Coruña, which finalized in 2008. For the last two years he has been working, at the Computer Architecture Group of the University of A Coruña developing GIS applications (making intensive use of many OGC standards) like Sitegal and SIUXFor (web GIS based applications to manage land properties and promote their good uses in the Galician region), MeteoSIX (a GIS system that provides access to geolocated observed and forecasted meteorological data in Galicia) and others. He also has large experience (3+ years) as a developer of mobile applications, having played first with JavaME, but nowadays he specializes in Google Android, with more than a dozen developed applications, some of them combining concepts like GIS and geolocation, real time responsiveness, and multiuser needs. Alan Palazzolo has been building web applications big and small for over five years, most of which have been with the open source, content management system Drupal, and along the way has picked up some experience in data visualization and mapping. He is a strong believer and advocate for the open source methodology in software and in life. He was involved in starting a Free Geek chapter in the Twin Cities, and constantly tries to use technology, and specifically the Internet, to enhance the lives of those that are less fortunate than most. Ian Turton is a geography researcher at the Pennsylvania State University. He became a geographer by accident nearly 20 years ago and hasn't managed to escape yet. During that period he was a co-founder of the GeoTools open source Java toolkit that is now used as the basis of many geographic open source projects. He continues to serve on the Project Steering Committee for the project as well as committing new code and patches. He has also taught the very popular course "Open Web Mapping" using open standards and open source programs at the Pennsylvania State University and the University of Leeds. www.PacktPub.com Support files, eBooks, discount offers, and more You might want to visit www.PacktPub.com for support files and downloads related to your book.

Supervisors Dr.Nikolas Prechtel Dr.Sander Münster Submitted on: 18th September 2017 Faculty of Environmental Sciences Institute for Cartography Task for the preparation of a Master Thesis Name: Mussab Mohamed Abuelhassan Abdalla Matriculation number: 4118733 Matriculation year: 2014 Title: Concept and Implementation of a Contextualized Navigable 3D Landscape Model: The Uch Enmek Example(Altai Republic,Siberia). Objectives of work Scope/Previous Results:Virtual Globes can attract and inform websites visitors on natural and cultural objects and sceneries.Geo-centered information transfer is suitable for majority of sites and artifacts. Virtual Globes have been tested with an involvement of TUD institutes: e.g. the GEPAM project (Weller,2013), and an archaeological excavation site in the Altai Mountains ("Uch enmek", c.f. Schmid 2012, Schubert 2014).Virtual Globes technology should be flexible in terms of the desired geo-data configuration. Research data should be controlled by the authors. Modes of linking geo-objects to different types of meta-information seems evenly important for a successful deployment. Motivation: For an archaeological conservation site ("Uch Enmek") effort has already been directed into data collection, model development and an initial web-based presentation.The present "Open Web Globe" technology is not developed any further, what calls for a migra- tion into a different web environment.

INTERNATIONAL EXPERTS’ MEETING ON ASSESSMENT AND PROGNOSIS IN RESPONSE TO A NUCLEAR OR RADIOLOGICAL EMERGENCY (CN-256) IAEA Headquarters Vienna, Austria 20–24 April 2015 Context In nuclear disaster affecting agriculture, there is a need for rapid, reliable and practical tools and techniques to assess any release of radioactivity The research of hazards illustrates how geographic information is being integrated into solutions and the important role the Web now plays in communication and disseminating information to the public for mitigation, management, and recovery from a disaster. 2 Context Basically GIS is used to provide user with spatial information. In the case of the traditional GIS, these types of information are within the system or group of systems. Hence, this disadvantage of traditional GIS led to develop a solution of integrating GIS and Internet, which is called Web-GIS. 3 Project Goal CRP1.50.15: “ Response to Nuclear Emergency affecting Food and Agriculture” The specific objective of our contribution is to design a prototype of web based mapping application that should be able to: 1.

  • Web Map Tile Services Tiny Tile Server Bachelor Thesis
    Web Map Tile Services Tiny Tile Server Bachelor Thesis Department of Computer Science University of Applied Science Rapperswil Spring Term 2013 Author: Carmen Campos Bordons Advisor: Prof. Stefan Keller, HSR Project Partner: Klokan Technologies, Baar External Co-Examiner: Claude Eisenhut, Burgdorf Internal Co-Examiner: Prof. Dr. Andreas Rinkel, HSR Abstract Tiny Tile Server is a Python server that permits the user to display local MBTiles maps on the internet. It extracts the data from the SQLite database where the map information is stored in tables containing all the tiles, UTFGrid and metadata. The tiles are the map images, smaller than the screen for better performance. The UTFGrid is some extra information related with points in the map that appears in an infobox when the user interact with these points. The metadata is the information about the map: name, description, bounds, legend, center, minzoom, maxzoom. Tiny Tile Server shows the tiles composing the map on a website and the UTFGrid data on top of the tiles. It can also be used to show the getCapabilities information from Web Map Tile Service in XML format extracted by the metadata table. Tiny Tile Server supports two protocols to access the tiles: direct access with XYZ tile request to tiles in a directory or to MBTiles database; or Web Map Tile Service from a MBTiles database. The server is a part in a website whose purpose is to show how it works and provide templates for the user who wants to employ it, so he will not need to have programming knowledge in order to use Tiny Tile Server, just to follow a simple installation tutorial.

Developing Web Applica- tion to serve spatial data to users Instructor Pages Jari Isohanni 29 + 7 Supervisor Jari Isohanni This study is aimed to give a basic understanding of web GIS from a technological point of view. Also, how the approach is useable for other technologies. The technologies including JavaScript API for Google Maps and ArcGIS were tested with demonstration. Additionally, the open-sourced solu- tions are discussed with the self-hosted server, PostgreSQL database. And with Openlayers as the front-end JavaScript library to present the geospatial data. During the study, in the Google Maps API demonstration, the GeoJson data is made by geojson.io and attitude data of the spatial data is called with the API method, to create popup windows for each city area. Another layer that represents specific location for the school, park, and hospital at Kokkola area is marked out with Google Maps API marker and it is overlaid, on top of that city area layer. The same spatial data and its related attribute data are implemented once more with ArcGIS JavaScript API to find out what is the difference between these two technologies. The result is that the Google Maps JavaScript API does not need to have a popup template to have the popup functionality working, instead of popup template, in the Google Maps JavaScript API, the click event listener is created to handle the popup event.

  • Comparison of Tile Server Design Approaches for 3-D Geo-Visualization
    COMPARISON OF TILE SERVER DESIGN APPROACHES FOR 3-D GEO-VISUALIZATION Tao Wanga, Jianhua Gongb aState Key Laboratory of Remote Sensing Science ,Institute of remote sensing applications chinese academy of sciences - [email protected] bState Key Laboratory of Remote Sensing Science ,Institute of remote sensing applications chinese academy of sciences - [email protected] Commission VI, WG VI/4 KEY WORDS: Tile server, Wms, Visualization ABSTRACT: In order to display large-scale maps on the Internet, it is necessary to divide the huge spatial data into small tiles. And servers are needed to support the display across network. There are two kinds of tile server. One is tile server, which organizes the pre-rendered tiles on the server. Another one is MapServer, which generates the display tile. In this article, different servers are compared in efficiency. The open source software world wind is used to analyze the capacity of the two kinds of servers, and experiment results show that tile server spent more time than Mapserver, and it is suggested the Mapserver may have been optimized. 1.

  • Implementation of a Geoserver Application for GIS Data Distribution and Manipulation
    Department of Physical Geography and Quaternary Geology Implementation of a Geoserver application for GIS data distribution and manipulation Karteek Kommana Master’s thesis NKA 79 Physical Geography and Quaternary Geology, 45 Credits 2013 Preface This Master’s thesis is Karteek Kommana’s degree project in Physical Geography and Quaternary Geology at the Department of Physical Geography and Quaternary Geology, Stockholm University. The Master’s thesis comprises 45 credits (one and a half term of full- time studies). Supervisors have been Göran Alm at the Department of Physical Geography and Quaternary Geology, Stockholm University and Stefan Ene, Department of Human Geography, Stockholm University. Examiner has been Peter Schlyter at the Department of Physical Geography and Quaternary Geology, Stockholm University. The author is responsible for the contents of this thesis. Stockholm, 12 June 2013 Lars-Ove Westerberg Director of studies Abstract Accessibility and Interactivity are keywords of information today and that is equally important in science as anywhere else. When scientists share information it benefits if it is intuitive, informative and simple and does not demand expert skills in complicated formats. This master thesis has the aim to investigate open source software tools to design a web map application that can be used by any institute or NGO to distribute their data over internet. The Java platform to be implemented is the open source OpenLayers which allow users to view and potentially manipulate GIS map data through a web map application. Whatever GIS data made available on the Geoserver (the host site for the application) can be shared to users worldwide. The user can then: add from a list of available data layers, choose background (e.g.
