Comenzó su andadura en 2004 de la mano de Steve Coast. La información la introducen y mantienen actualizada usuarios voluntarios de todo el mundo. Toda la información de la base de datos es de libre acceso y utilización. A la fecha de escribir estas notas había más de cuatro millones millones cuatrocientos mil usuarios registrados y el volumen de información almacenado era de unos 60 Gigabytes en formato comprimido (más de 800 Gb descomprimidos). Por ejemplo, el número de nodos almacenados a la fecha era de unos cuatro mil millones doscientos veintitres mil con tresmillones de juegos de cambios diarios. Las estadísticas actualizadas de uso se pueden consultar en el siguiente enlace: 3 ICE OSM Documentation, Release 1.0 4 Chapter 1. Introducción ICE OSM Documentation, Release 1.0 1.1 Flujo de trabajo en la descarga y utilización de datos OSM El flujo de trabajo con datos procedentes de OpenStreetMap suele seguir las siguientes fases (ver figura ): • 1.- Descarga de datos brutos de OSM: en primer lugar se trata de obtener los datos existentes en la base de datos de OpenStreetMap correspondientes a la zona que estemos estudiando. Normalmente se obtienen todos los datos de una determinada zona en algunos de los formatos que nos ofrece OSM. El más habitual es el formato .osm, que es un formatos XML. • 2.- Procesamiento de datos brutos y extracción de los elementos de interés: Habrá que extraer de los ficheros obtenidos de la base de datos, los elementos en los que estemos interesados. Si por ejemplo estamos haciendo un estudio acerca de las carreteras de una zona, habrá que extraer todos los elementos del tipo Node, Way o Relation que tengan información acerca de las carreteras. • 3.- Conversión a otros formatos vectoriales: normalmente trabajaremos en un programa GIS o con una base de datos. Los datos que nos interesan, y que hemos extraido en la fase anterior, habrá que convertirlos al formato en el que tengamos pensado trabajar. Puede ser un formato vectorial como el shapefile o quizás haya que importarlos desde la base de datos con la que pensemos hacer el análisis. • 4.- Procesamiento y cálculos: una vez se dispone de los datos en nuestro formato de trabajo, realizaremos los cálculos y operaciones de análisis espacial que nos interesen. • 5.- Salida gráfica o alfanumérica de los resultados: por último, habra que plasmar los resultados de nuestro trabajo en forma gráfica o mediante los informes correspondientes. 1.1. Flujo de trabajo en la descarga y utilización de datos OSM 5 ICE OSM Documentation, Release 1.0 A día de hoy hay muchas herramientas que pueden ser utilizadas en cada una de las fases descritas. En este taller vamos a dar algunas ideas de cómo utilizar algunas de ellas. Existen en la red numerosos documentos que han servido para la preparación de esta documentación y que pueden ser consultadas para ampliar la información que aquí se explica. # primitivas 6 Chapter 1. Introducción CHAPTER 2 Estructura de la información en OSM OSM es una base de datos de información geográfica. Los elementos o fenómenos existente en la realidad se modelizan mediante la incorporación a la base de datos de dos niveles de información para cada uno de ellos: • Información espacial: contiene la información relativa a la geometría y posición del fenómeno. Responde a la pregunta ¿Dónde? • Información temática: contiene las características y propiedades del fenómeno. Responde a la pregunta ¿Qué? En la base de datos de OSM a cada fenómeno de la realidad que se quiera modelizar se le asigna una primitiva geométrica que le dota de la información espacial. Hay tres tipos de primitivas geométricas: • Node: corresponden a fenómenos cuya geometría se modeliza con un punto • Way: corresponden a fenómenos cuya geometría se modeliza mediante una línea abierta o cerrada. • Relation: combinan Nodes, Ways y otras Relations para definir geometrías o elementos complejos La información temática se incorpora al modelo mediante etiquetas, tags, que son parejas de cadenas de texto en la forma key-value. Cada primitiva geométrica lleva asociadas un número indeterminado de etiquetas que permiten definir su información temática. Se pueden consultar las etiquetas más frecuentes en la página: http://wiki.openstreetmap.org/wiki/Map_Features Cada primitiva geométrica tiene una serie de atributos que permiten caracterizar a los elementos que representan: • id: Es el identificativo del elemento en la base de datos. A cada elemento le corresponde un id único, mediante el cuál es posible identificarlo en la base de datos. Hay tablas diferentes en la base de datos para los elementos del tipo node, way o relation, y cada una de ellas tiene su lista de id’s. Por ello, puede suceder que un elemento node tenga el mismo id que un elemento way, por ejemplo, pero al tratarse de distinto tipo de elemento, la identificación sigue siendo única. • version: la primera vez que se graba un elemento en la base de datos se le asigna el número de versión 1. Este número de versión se va incrementando cada vez que el elemento se actualice o se le realicen modificaciones en sus atributos o tags. • changeset: Cada vez que un usuario realiza una serie de cambios y los sube a la base de datos de

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.

  • Lowering the Barrier to Osm Contribution and Citizen Mapping Services Development for City Governments
    LOWERING THE BARRIER TO OSM CONTRIBUTION AND CITIZEN MAPPING SERVICES DEVELOPMENT FOR CITY GOVERNMENTS Chao-Kuei Hung1 1Chaoyang University of Technology, [email protected] Abstract This article uses a mapping program potluckmap to propose two ways for city governments to improve tourist experiences. By focusing on nodes only, OpenStreetMap editing can be reduced to collaborative spreadsheet editing. Hopefully lowering the barrier to contribution will bring more local business owners to advertise themselves on OSM. By separating the real-time bus position information from the map drawing, more bus companies can easily make their information available to tourists, and tourists can use a single map application to navigate in many cities across the globe. Keywords: OpenStreetMap, tourism, local businesses, public transportation 1. BACKGROUND AND THE PROBLEMS More and more city governments learn to open up their data to the public and make use of the results from public participation projects such as OpenStreetMap and software projects with Free/Libre and Open Source Software (FLOSS) licenses. The released data feed FLOSS projects such as mobile apps and/or websites for transportation and tourism information, thereby benefiting residents and local businesses without taxing city governments on their software development resources. In OSM, area- and street-information is relatively complete in many cities, but Poin- of-Interest (POI) information such as restaurants, shops, and entertainment spots is typically quite incomplete or even sparse even in big cities. Even with the advancement of OSM editors such as JOSM and iD, the entrance barrier to OSM editing contribution is still considerably higher than that to Wikipedia contribution for example.

  • Rethinking the Usage and Experience of Clustering Markers in Web Mapping
    Rethinking the Usage and Experience of Clustering Markers in Web Mapping Lo¨ıcF ¨urhoff1 1University of Applied Sciences Western Switzerland (HES-SO), School of Management and Engineering Vaud (HEIG-VD), Media Engineering Institute (MEI), Yverdon-les-Bains, Switzerland Corresponding author: Lo¨ıc Furhoff¨ 1 Email address: [email protected] ABSTRACT Although the notion of ‘too many markers’ have been mentioned in several research, in practice, displaying hundreds of Points of Interests (POI) on a web map in two dimensions with an acceptable usability remains a real challenge. Web practitioners often make an excessive use of clustering aggregation to overcome performance bottlenecks without successfully resolving issues of perceived performance. This paper tries to bring a broad awareness by identifying sample issues which describe a general reality of clustering, and provide a pragmatic survey of potential technologies optimisations. At the end, we discuss the usage of technologies and the lack of documented client-server workflows, along with the need to enlarge our vision of the various clutter reduction methods. INTRODUCTION Assuredly, Big Data is the key word for the 21st century. Few people realise that a substantial part of these massive quantities of data are categorised as geospatial (Lee & Kang, 2015). Nowadays, satellite- based radionavigation systems (GPS, GLONASS, Galileo, etc.) are omnipresent on all types of new digital devices. Trends like GPS Drawing, location-based game (e.g. Pokemon´ Go and Harry Potter Wizard Unite), Recreational Drone, or Snapchat ‘GeoFilter’ Feature have appeared in the last five years – highlighting each time a new way to consume location. Moreover, scientists and companies have built outstanding web frameworks and tools like KeplerGL to exploit geospatial data.
