The One and Many Maps: Participatory and Temporal Diversities in OpenStreetMapDongpo Deng
OpenStreetMap is an open and collaborative project with thousands of people contributing GPS traces and other data into the making of a global map of places and networks. It is open in the sense that everyone can contribute to the project, and results from the project are free for everyone to reuse. This is contrary to traditional cartography where often a central authority controls the making of the map and its release. Is OpenStreetMap more democratic, and in what sense? Is OpenStreetMap more relevant to the mass, and how can we judge?
We define and use several metrics to measure temporal properties of dened areas in OpenStreetMap, and to sample modes of participation in these areas. These metrics are used to graph the datasets representing the current OpenStreetMap so as to reveal unevenness in user participation and data temporality. We use the dataset about Taiwan as a test case to observe participatory and temporal diversities among different areas of Taiwan in OpenStreetMap.

A Software Tool for Rapid Acquisition of Streetwise Geo-Referenced MapsVladimir Kulyukin
RapGeoRef, a software tool for rapid acquistion of streetwise geo-referenced maps, is
presented. A evaluation study of RapGeoRef was performed on the USU campus with four students.
The participants were told about the purpose of the tool and shown a demo. They were
then asked to construct a geo-referenced database for an area of the USU campus. Upon
completion, they were given the NASA TLX questionnaire to assess the subjective
workload.All participants were able
to complete the task in one day. The analysis of the NASA TLX questionnaire revealed
that the temporal demand was much more prominent to the participants than either
mental or physical effort.

OpenStreetMap and CycleStreets: collaborative map-making and cartography in t...CycleStreets
Abstract: The arrival of web-based mapping from Google and others has revolutionised, in the space of only five years, the way many people interact with maps and map data. And the success of projects such as Wikipedia highlight how collation of small amounts of information from large numbers of people - an approach called 'crowdsourcing' - can challenge traditional models of data collection and ownership. Bringing these concepts together is OpenStreetMap, a collaborative project to create a free editable map of the world. Well-established enterprises such as the Ordnance Survey are coming under increased pressure from this new model, and large companies such as MapQuest and Microsoft are starting to use and invest in it. Martin Lucas-Smith, Webmaster in the Department, and one of two main developers of the leading UK-wide cycle journey planner website, CycleStreets, will discuss OpenStreetMap, its use within a wide range of systems (from cartography, routing, and even its central role helping deal with the Haiti disaster) and discuss the challenges it poses to traditional forms of cartography and data collection.
The document discusses OpenStreetMap (OSM), a collaborative project to create a free editable map of the world. It provides details on OSM's history starting in 2004, how the platform works through centralized databases and APIs, how users map through tracing imagery or field work, and the open data licensing. It then focuses on the Humanitarian OpenStreetMap Team which coordinates mapping efforts for disaster response and developing areas. Specific projects in Haiti, Kenya, Gaza, and Pakistan are reviewed. The document closes with discussion of government involvement in OSM mapping and potential opportunities for OSM in Sri Lanka.
1) The presenter discussed the role of neogeography and volunteered geographic information (VGI) in crisis mapping during and after the 2011 Tohoku earthquake and tsunami in Japan.
2) Case studies were presented on how OpenStreetMap and Ushahidi's Sinsai.info platform were used to collect and map crowdsourced geographic information from social media to support relief efforts.
3) Long-term efforts included creating detailed restoration maps of affected areas through mapping parties and fieldwork with local residents to document rebuilding progress over time.
OpenStreetMap: Shared data for competitive servicesStefano Sabatini

In my presentation for State Of The Map 2011 in Denver, I loosely connect three topics: the Warm Geography (expressed by Data Temperature) that makes OpenStreetMap unique; the challenge of converting sign-ups to contributors in what I call the First Mile, and finally how ideas from gaming can help meeting that challenge and preparing OpenStreetMap for 4 million contributors.
Quality assessment for crowdsourced geographic informationMartijn van Exel
The document discusses the challenge of assessing the quality of crowdsourced geographic information. It proposes a novel approach called "Crowd Quality" that leverages unique characteristics of crowdsourced data like user ratings, feature versions, age and persistence, and spatial flux. This approach does not require a reference dataset and can account for local variations in quality.
OpenStreetMap and the Art of Motorcycle MaintenanceMartijn van Exel
This document discusses OpenStreetMap and crowd-sourced mapping. It presents data on four mappers - their time mapping, number of edits, and use of GPS traces. It also examines crowd quality indicators for OpenStreetMap like number of map versions, users, age of the data, and changes to features over time. Finally, it raises challenges with processing large OSM data, accessing private GPS traces, and interpreting the crowd quality metrics.
The document discusses the concept of map quality. It begins with examples of cities around the world and their representation on maps. It then asks what defines good map quality and whether more data necessarily means better quality. The document questions if map quality is defined by the data or other factors. It references a quote about determining what is good versus not good without needing others' opinions.
This document lists locations and dates for events in Almere, Delft, and Amsterdam. It also mentions a Carnaval map, Frysian map, and a beta web application for reporting errors.

WelcomeI would like to spend the next 30-40 minutes with you talking about OpenStreetMap:An OSM primer: what is it, how it came about.Some examples of how OSM is being usedSpecial considerations with regard to data qualityPractical OSM if there’s time left.
OpenStreetMap is is a free editable map of the whole world. It is made by people like you.OpenStreetMap allows you to view, edit and use geographical data in a collaborative way from anywhere on Earth.OpenStreetMap is a prime example of VGI, Volunteered Geographic Information, a term devised by Michael Goodchild to capture the harnessing of tools to create, assemble, and disseminate geographic data provided voluntarily by individuals.Let’s break this brief explanation of OSM down a bit.
Free does not only mean that you don’t have to pay to acquire the data, it also means that you can use it without many of the licensing restrictions that proprietary data sets are burdened with. Basically you can use it for anything you like, as long as you give proper credit to OpenStreetMap, and you share anything you create using OpenStreetMap under these same terms.
It’s editable, which has enormous implications for the data and its uses. 450,000 people have signed up to contribute to OSM, although as we will see, not all of them are actively contributing data.The fact that anyone can go in and edit the data means that OSM is in a constant state of flux. The data you download today will not be the same as the data you download tomorrow. There is no guarantee that every single contribution actually improves the map. Contributors may inadvertently or purposefully vandalize the map. Let’s have a look at how OpenStreetMap editing works.
The basic data model is extremely simple. There’s nodes, which are points with X and Y coordinates. A node can have an arbitrary amount of attributesWays are ordered sets of nodes interpreted as a line or an area. Ways can also have attributes in the form of key-value pairs.Relations are groups of ways and / or nodes that have a functional or geographical relationship. Examples of relation use is for multipolygons, but also bus routes and turn restrictions.
Here’s an example of an OSM object, describing the University library. It has a unique ID, a timestamp telling us when it was last edited, the version number, the changeset number – a changeset is basically an editing session – and the user who last edited the object (me). Then the nodes out of which this way feature is built up. Note that no coordinates are stored in the way object itself.Lastly the tags, which are the attrributes. How do you know which to use?
OpenStreetMap does not have real standards, it has conventions. The most common attributes are agreed upon using a voting system, the OpenStreetMap wiki and the mailing lists. Anyone can propose a new tag and have the community discuss it and vote on the proposal. There is nothing that will stop you from starting to use your own tags right away, though. You can map whatever you want, as long as it’s verifiable.
Let’s look at the editors. There are many, also for mobile devices. I will discuss the most prominent ones here. The most visible editor is called Potlatch, and it’s available in the edit tab on the web site. It allows you to do all but the most complex editing tasks in a relatively user-friendly environment. There is also a sandbox mode that does not save your edits.
JOSM is the full featured desktop OpenStreetMap editor. It has the editing and manipulation features of a modern desktop GIS.
OSM was started in 2004 in the UK, out of frustration by a group of students unable to get a hold of good quality geospatial data. It has since spread all over the world. This movie shows the growth of OSM in 2008.What we see is that some areas, notably the US, see a sudden influx of data. This is because OSM is not only fed by individuals contributing local knowledge, but also by data imports. For the US, we have seen the TIGER line data import in early 2008. Look at that in detail.
The fact that OpenStreetMap is free and editable has inspired people with very different backgrounds and interests to create very diverse things Let's look at a few examples
This is taken from OpenCycleMap. It is a web site that highlights things that are interesting and important for cyclists: bike paths and lanes, repair and parts shops, signposted routes, trails.
This is a topographic map style as seen on toposm.org. Here, OpenStreetMap is combined with several other map sources to create a nice looking general purpose map.
Decidedly less useful but an interesting take on mapping are these city maps inspired by the 8-bit home computer graphics of the 1980. OpenStreetMap data was used to create these maps.
OpenStreetMap is also keeping folks warm on these blankets that you can have custom made from softcities.
OpenStreetMap can also be seen outdoors. Here's an example of a tourist information display in the Croatian town of Sinj (left), and an information display in a bus shelter in Kosice, Slovakia.
An example of OpenStreetMap used in a print publication. Nike Grid was an urban game run by Nike in the UK in 2010 where the players earned points for completing runs in a grid consisting of postal code regions.Interestingly Nike used the OpenStreetMap-based maps without the required attribution. This was later added.
OpenStreetMap also allows Kindle users to have maps on their devices. Because of the limited screen capabilities, a specialized cartography needed to be designed. OpenStreetMap offers the flexibility to do that.
This is a routing web site. On the surface it looks like many you may have seen. This particular one however is aimed at wheelchair users. Wheelchair routing requires information on steps, curbs, inclines and other potential obstacles for wheelchair users. This information is not available in existing maps, so they added it themselves in OpenStreetMap and used OSM for calculating the wheelchair routes.
OpenStreetMap can also be used to power navigation devices. In Russia, OpenStreetMap is the only map that provides door to door navigation in some areas.
OpenStreetMap has one defining quality: it's warm geography. People sharing their knowledge about their own neighborhoods.
First I plan to go into what motivates people in general - as defined in the classic Maslov hierarchy of human needs. The dimensions particularly interesting for OSM are a the ones higher up in the hierarchy: sense of belonging, esteem and self-actualization. I am not an expert on this so I'm just going to go into this briefly. I then plan to connect this to gaming and how playing (certain kinds of) games taps into these needs.
Initial idea was about badges.Has drawbacks – people just in it for the badges,It should be about more that just quantitative achievements
Introduce the topic.Gaming and qualityCreate tension – how could gaming help OSM?
