Towards emergency vehicle routing using Geolinked Open Data: the case study o...Sergio Consoli
Linked Open Data (LOD) has gained significant momentum over the past years as a best practice of promoting the sharing and publi- cation of structured data on the semantic Web. Currently LOD is reach- ing significant adoption also in Public Administrations (PAs), where it is often required to be connected to existing platforms, such as GIS-based data management systems. Bearing on previous experience with the pi- oneering data.cnr.it, through Semantic Scout, as well as the Agency for Digital Italy recommendations for LOD in Italian PA, we are working on the extraction, publication, and exploitation of data from the Geographic Information System of the Municipality of Catania, referred to as SIT (“Sistema Informativo Territoriale”). The goal is to boost the metropolis towards the route of a modern Smart City by providing prototype inte- grated solutions supporting transport, public health, urban decor, and social services, to improve urban life. In particular a mobile application focused on real-time road traffic and public transport management is currently under development to support sustainable mobility and, espe- cially, to aid the response to urban emergencies, from small accidents to more serious disasters. This paper describes the results and lessons learnt from the first work campaign, aiming at analyzing, reengineering, linking, and formalizing the Shape-based geo-data from the SIT.
In this presentation we report progress on a climate change impact assessment in Guatemala and a comparison of our methodology with alternatives for coffee to the steering comittee of the Coffee and Climate Initiative. http://www.coffeeandclimate.org/

The many-uses-of-gtfs-data-–-its-america-submission-abbreviatedCTeixeira2
The General Transit Feed Specification, or GTFS, has become the most popular world-wide data
format to describe fixed-route transit services. Many transit agencies have created and published
GTFS data with the primary purpose being integration with Google Maps. However, GTFS data
can power many other different types of transit and multimodal software applications, including
multimodal trip planning, timetable creation, mobile apps, visualization, accessibility, analysis
tools for planning, real-time information, and interactive voice response (IVR). This paper
provides an overview of the many opportunities available for transit and intermodal agencies to
leverage open GTFS data and provide many new types of information services to the public or
their internal operations with little to no cost to the agency. For transit agencies without open
data, this paper will inform decisions on prioritizing and justifying investments in open data
initiatives. For agencies that already provide open access to GTFS data, this paper will assist the
agency in maximizing their investment in GTFS data by providing resources on how to access
many new types of applications. Departments of Transportation, Metropolitan Planning
Organizations, and other intermodal agencies will also benefit from this paper by learning the
state of the art in transit information dissemination, which can power new state-of-the-art
intermodal applications. This paper also provides a summary of industry best-practices that an agency can follow when deciding to create and share an open GTFS data feed to maximize exposure to new applications.
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.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

11. Assembling Best Available Data Starting with ITOS data: A combination of VMAP1, DCW and national sources CIESIN is: editing topology contributing new data by cleaning GPS derived data (e.g. Kenya), Landsat derived data (e.g. Nigeria), and Global Map (ISCGM) data combining data from multiple sources (e.g., DCW and Africover for Tanzania) conducting pilot projects that will provide new data for Ethiopia 11
12. Contacting national mapping agencies Letter extract: “As a first step in creating this data set, we are contacting agencies such as your own to obtain permissions to incorporate existing national level data of suitable quality for inclusion in gROADS. In the next phase, we will be creating the infrastructure necessary to update these data in a distributed manner, so that those who contribute data can expect, within a three to four year time frame, to see improvements to their original dataset through the inputs of a wider community. Semi-automated means for facilitating distributed contribution of GPS tracks and digitizing tracks off of imagery are both being pursued as well as efficient means for gathering information about road characteristics. Since all data will be distributed free and clear of copyright restrictions, the data you contribute, plus any additions or enhancements, will be available to your organization at any time for extraction from gROADS. Any enhancements will be clearly documented in terms of the source of the updates. Thus, you obtain continuing visible credit for any contributions because each data source will be documented in the accompanying data documentation. Furthermore, your organization will be listed as a supporting data contributor on the gROADS wiki. You may highlight on your own website that your organization is a recognized official contributor of gROADS, and your organization will be granted authority to use the trademarked gROADS contributor logo in conjunction with this statement. “We hope that you will agree that by contributing data to this initiative, you will not only benefit your own organization but also the wider community. If you are in agreement, we would be happy to send you a permissions form to be filled out, signed, and returned. We will be using the standardized Public Domain Dedication and License (PDDL) for this new and evolving dataset. Only in rare instances and for very large data collections will we accommodate other open access licensed contributions and these will be only on a temporary basis until such time as the data has been replaced through the distributed upgrading process.” An arrangement whereby governments give their roads data in the expectation of receiving better data in return 12
13. NASA-SERVIR Project (Ethiopia) Pilot tested a semi-automated road extraction tool developed by the Center for Spatial Information Science at University of Tokyo Target was ASTER imagery for Ethiopia The alpha version of the software was comparable to manual digitizing line following algorithm underperforms due to similar spectral signature for roads and surrounding land covers Average time per scene ~8hrs (depending on rural vs. urban and number of roads) 13
