OpenStreetMap Brighton 0.9999

This document summarizes the progress of OpenStreetMap in Brighton over the past year. It discusses how OSM started as an experiment in 2006 and has grown significantly since, with over 270 miles of roads now mapped in Brighton. The document outlines the current mapping process used by contributors and highlights goals for the future, such as mapping all roads, footways, bicycle paths, and public buildings to reach version 1.0 of the Brighton map. It concludes by discussing plans for a launch event in November to promote OSM to local government and community groups.

Social Media in Local Government and the GIS user

Gletham Communications

Presentation at MISA BC conference, Sidney BC by Glenn Letham @gletham discussing the use of social media by official local government agencies, with emphasis on the GIS department and Geo user. A look at social media policies, tools, uses, and the impact of social media on mobile technology, opengov, local government, and citizen engagement.

FreeMap Palestine November 2008

1) OpenStreetMap is a collaborative project to create a free editable map of the world. Volunteers can collect and upload geographic data like streets, roads, trails, and points of interest using simple digital mapping tools. 2) The OpenStreetMap project aims to build a freely-available map of the world that can be used and shared by anyone for any purpose. It provides an alternative to proprietary map data that is often closed, inaccurate, or outdated. 3) OpenStreetMap is being used around the world for navigation, urban planning, agriculture, ecology, disaster response, and more. In developing areas, it is empowering communities by allowing them to map local areas and advocate for issues like housing rights

This document outlines a UX methodology for a tourism and biodiversity project. It includes sections on planning, prototyping, personas, ecosystems, benchmarking and more. The key stakeholders identified are consumers interested in taking action, NGOs promoting biodiversity projects, funders interested in projects, territories with political will, and companies committed to progress. It also includes a backlog section and mentions creating user stories. The overall goal is to design a process to engage stakeholders in sustainable tourism that benefits biodiversity.

Big Data: Business Case in Alicante

Antonio Sánchez Zaplana

The document discusses two business cases for using big data in water utilities in Alicante, Spain. The first case focuses on using big data and a decision support system to optimize asset management and infrastructure renewal planning. The second case examines using big data from smart water meters to promote more efficient water use among citizens. Both cases aim to help the utility better manage infrastructure investments and customer water demand given Alicante's scarce water resources and increasing population.

A Brief History of Open Geospatial

Arnulf Christl

The talk tells the story of how Open Source GIS developers founded the geospatial standards organization OGC in the early 1990s, long before the term “Open Source” was even coined. The story goes on to describe how Open Source geospatial activists founded OSGeo in 2006, why the current big topic is Open Data and how it all ties together. This need for openness is intrinsic to geospatial because any location makes sense only relative to other location data. Interoperability is a must.

Five Myths About GIS in 2011

OpenStreetMap at Wikimania

OpenStreetMap is a collaborative project to create a free editable map of the world. It allows users to collect and share geographic data and edit maps. The project aims to build a map that is free of errors and restrictions, and that anyone can use and improve. It has grown rapidly since its founding in 2004 and now has a large amount of mapped data across Europe and parts of Africa and Asia. The project hopes to continue expanding worldwide and learning from other collaborative projects like Wikipedia.

Rocket City Keynote

Learon Dalby

Who? What? Why we better care?

This document discusses how social media and mobile technologies are changing the landscape of data collection and sharing. Key points discussed include: - Social media tools like Twitter and location-based services allow widespread collection of geotagged data from users. - Mobile devices are becoming the primary way people access and share data. This will impact application development and how information is input and output. - Crowdsourcing of data from many individuals through social media could challenge traditional notions of authoritative data sources and funding models. - New opportunities exist to involve communities and different stakeholders in data collection and decision making in ways not previously possible. Standards and policies may need to change in light of these new technologies and practices.

MapQuest: How OSM Benefits & Vice Versa

Randy Meech

The document discusses how open-source mapping can benefit the navigation and location-based services industries. It summarizes MapQuest's investments in OpenStreetMap, including hiring contributors and hosting tools and services. While commercial data is still needed for some uses like navigation, open data is increasingly competitive for many applications. The author believes open data will not completely replace commercial data due to needs like ensuring roads are driven, but it will continue growing in importance. MapQuest is launching new open products like an SDK and aerial tiles to engage developers and further open mapping.

TigerGraph

This document summarizes a webinar about using TigerGraph for geospatial analysis. It discusses representing location data as a graph with grid vertices connected to object vertices. This allows expressing geospatial queries naturally in GSQL. The webinar demonstrates this approach using California healthcare facility location data. Attendees can explore the live graph and run queries on a demo UI. TigerGraph is well-suited for geospatial analytics due to its native support for graphs, ability to handle connected data, and performance on large datasets.

MVP OSM

Maurizio Napolitano

The document discusses MVP OSM, a tool that allows users to identify areas of high activity on OpenStreetMap based on the level of detail. It summarizes how MVP OSM works by importing OSM data into a Spatialite database, analyzing user contributions to identify the most active ("valuable players"), and generating heat maps of activity hotspots. The tool could help recognize highly engaged mappers and understand patterns of contributions on OSM.

GISRUK conference

This document discusses spatial data quality issues in OpenStreetMap (OSM) geo-applications. It finds that OSM data quality depends on factors like the structure of how features are extracted and attributed, the number and popularity of tags used, and inconsistencies between users. While OSM allows freedom and an open voting system, this can negatively impact data quality by introducing errors and discrepancies. Formalizing specifications and quality assurance processes may help address these challenges.

Crowdsourcing

OpenStreetMap and the Art of Motorcycle Maintenance

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.

Zen of Map Quality

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.
