The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive function. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms.
The document provides an overview of OpenStreetMap (OSM) including that it is a free and open map of the world created from crowdsourced data. It describes how OSM uses a wiki-style model for mappers to collect and edit geographic information. The document then outlines the basic steps mappers should follow which include preparing with tools like GPS, collecting data in the field, uploading GPS traces, and using an editor to map locations and add tags.
This document provides an overview of OpenStreetMap (OSM), including its major components, mapping techniques, data sources, editing tools, and rendering systems. OSM is a collaborative project that allows volunteers to collect and edit geographic map data that is made publicly available under an open license. Mappers can contribute data through GPS traces, photos, or paper maps, and edit map features using online or offline editors. OSM data is stored in a PostgreSQL database and rendered into tiles using Mapnik for display on websites and mobile apps through a "slippy map" interface.
As we move further into the future of digital design, web design is no longer just about creating a single great desktop browsing experience. The interactive design industry is at a crossroads; mobile and tablet devices continue to propagate and fuel new interactions, and the web is now found on more devices than ever.
So, how do we adjust accordingly? More often than not, designers and programmers use old methodologies to tackle new problems. The real tool kit of a great web designer starts off-line and off-screen. This lecture will showcase important skills that will prepare flexible designs for future facing web projects. We will outline a set of new philosophies, collaborative processes and custom tools that enable productivity in this ever-changing world. We'll also cover the importance of creating your own tools and adapting to new needs, so you can stay ahead of the game.
By demonstrating the right workflow, the right tools and a future facing philosophy, this talk aims to help anyone who has thought to themselves: 'there has to be a better way'. The future isn't 12-column grids and pixel perfect PSDs. It's a flexible thinking model that relies on your understanding of development and a strong design philosophy.

Toward Next Generation of Gazetteer: Utilizing GeoSPARQL For Developing Link...Dongpo Deng
This document summarizes Dongpo Deng's presentation on developing linked geoname data using GeoSPARQL. It discusses transforming a Taiwanese place name dataset into RDF triples using a place name ontology. A linked data server and GeoSPARQL endpoint were created to serve and query the linked place name data. Spatial and temporal SPARQL queries over the data were demonstrated. The linked place names can be used as controlled vocabularies and are connected to other datasets like Geonames.org.
The document discusses how crowdsourced data from platforms like OpenStreetMap, Safecast, and social media can be used to address the impacts of climate change. OpenStreetMap allows anyone to collaboratively map the world and proved useful in mapping areas affected by the 2010 Haiti earthquake within weeks. Safecast crowdsources radiation level data with mobile devices and geiger counters to empower people with information. Social media platforms like Flickr have also been used to track phenomena like changing cherry blossom seasons that may be influenced by climate change. The document argues these informal sources can help collect scientific data and monitor climate impacts in a structured way.
This document discusses open geospatial data and engaging citizens in spatial data infrastructures (SDI). It defines open data and open geospatial data. It notes that while grassroots communities in Taiwan are active in open data, there is a lack of high-level policies. The document advocates for governments to act as platforms rather than vendors of data. It outlines different funding models and proposes a 4P approach (Policy, Principle, Process, Price) for open geospatial data. It highlights examples of engaging citizens from other countries and proposes actions Taiwan could take to open data and involve citizens in its SDI.
Social Web Meets Sensor Web: Linked Crowdsourced Observation DataDongpo Deng
This document discusses linking data from biodiversity observations on platforms like Galaxy Zoo, Audubon, and iNaturalist to semantic web standards like the Semantic Sensor Network ontology. It presents an example observation of a Chinese ferret badger from Taiwan expressed using these linked data formats and ontologies. The example includes details on the observation provider, photo, date, location, and taxonomic identification. It also shows SPARQL queries that could be used to retrieve observations from a specific place and time period.
