The Uch Enmek Example(Altai Republic,Siberia)
Faculty of Environmental Sciences Institute for Cartography Master Thesis Concept and Implementation of a Contextualized Navigable 3D Landscape Model: The Uch Enmek Example(Altai Republic,Siberia). Mussab Mohamed Abuelhassan Abdalla Born on: 7th December 1983 in Khartoum Matriculation number: 4118733 Matriculation year: 2014 to achieve the academic degree Master of Science (M.Sc.) 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. -

I Work for Natural Resources Canada in the Canada Centre for Mapping
I work for Natural Resources Canada in the Canada Centre for Mapping and Earth Observation, where as a technologist and developer, I have been supporting the development of geo-standards, spatial data infrastructure, or “SDI”, and open spatial data for about 10 years. 1 Today, I’m going to talk about the community, concepts and technology of the Maps for HTML Community Group. The objective of the Maps for HTML initiative is straightforward: to extend HTML to include Web map semantics and behaviour, such as users have come to expect of Web maps. 2 Before getting in to the technology discussions, I think it’s really important to back up and take stock of the situation facing mapping professionals today. 3 Paul Ramsey is a leader in the open source geospatial software development community who currently works for the CartoDB consumer web mapping platform. In a recent presentation to a meeting of Canadian government mapping executives, Paul told us that government mapping programs were no longer relevant. In fairness, Paul did say sorry for having to say that. You know, sometimes it is hard to hear the truth, and I would have to say that Paul wasn’t completely wrong, so what I really want to say in response to Paul is ‘thank you’. 4 Thank you for the opportunity to talk about a subject that has been in the back of my mind not just since I began promoting standards for geospatial information and Spatial Data Infrastructure, and open spatial data, but since the first day I did ‘View Source’ on an HTML page containing a Web map and did not see anything that could possibly produce a map. -

Introduction to Web Mapping April 3, 2017 Sarah Watson Overview
RDSC Workshop #5 Introduction to Web Mapping April 3, 2017 Sarah Watson Overview • What is Web Mapping • OpenStreetMap Overview • Brief Tutorials of: • Social Explorer • StoryMap • Carto Difference Between “Digital” and “Web” • Digital – involves a computer, but may not be accessible via the internet • Web Map – a type of digital map that is accessible in a web browser: • Maps.google.com • Openstreetmap.org • Web maps are connected to but different from maps made for mobile devices or for a digital globe (Google Earth) • Development really took off after the emergence of Google Maps • Many different platforms now exist OpenStreetMap • Sometimes referred to as the “Wikipedia of Maps” • Can be edited by anyone • Licensed under the Open Database License • Two ways to edit: • Web editor ID • Advanced editor JOSM OpenStreet Map • OpenStreetMap Task Manager From the website: “A mapping tool designed and built for the Humanitarian OSM Team collaborative mapping. The purpose of the tool is to divide up a mapping job into smaller tasks that can be completed rapidly. It shows which areas need to be mapped and which areas need the mapping validated.” • MapRoulette • From OpenStreetMap wiki: “A gamified approach to fixing OSM bugs that breaks common OpenStreetMap data problems into micro tasks.” Creating a Web Map While there are many different programs to create web maps, many require coding knowledge. Leaflet is a common, open-source JavaScript library used by many to create interactive, web maps Today, I want to highlight a couple different non-coding options.

Cartographic Redundancy in Reducing Change Blindness in Detecting Extreme Values in Spatio-Temporal Maps
International Journal of Geo-Information Article Cartographic Redundancy in Reducing Change Blindness in Detecting Extreme Values in Spatio-Temporal Maps Paweł Cybulski * ID and Beata Medy ´nska-Gulij Department of Cartography & Geomatics, Faculty of Geographic and Geological Sciences, Adam Mickiewicz University, Krygowskiego 10, 61-680 Pozna´n,Poland; [email protected] * Correspondence: [email protected]; Tel.: +48-61-829-6307 Received: 23 November 2017; Accepted: 28 December 2017; Published: 1 January 2018 Abstract: The article investigates the possibility of using cartographic redundancy to reduce the change blindness effect on spatio-temporal maps. Unlike in the case of previous research, the authors take a look at various methods of cartographic presentation and modify the visual variables in order to see how those modifications affect the user’s perception of changes on spatio-temporal maps. The study described in the following article was the first attempt at minimizing the change blindness phenomenon by manipulating graphical parameters of cartographic visualization and using various quantitative mapping methods. Research shows that cartographic redundancy is not enough to completely resolve the problem of change blindness; however, it might help reduce it. Keywords: animated map; cartography; change blindness; user testing; visual perception 1. Introduction Cartographic animation makes it possible to present spatial and temporal changes simultaneously. Even though technological progress has moved animated maps into the realm of the Internet and enabled users to view them in an interactive fashion, their perception is still problematic. As aptly noticed by [1], the problem with animated map perception is not caused by the technology itself, but rather by the limited perceptual capabilities of the user. -
