SDSC Technology Forum: Increasing the Impact of High Resolution Topography Da...OpenTopography Facility
High-resolution topography is a powerful tool for studying the Earth's surface, vegetation, and urban landscapes, with broad scientific, engineering, and educational-based applications. Over the past decade, there has been dramatic growth in the acquisition of these data for scientific, environmental, engineering and planning purposes. In the US, the U.S. Geological Society is undertaking the 3D Elevation Program (3DEP) to map the entire lower 48 with lidar by 2023.
The richness of these topography datasets make them extremely valuable beyond the application that drove their acquisition and thus are of interest to a large and varied user community. A cyberinfrastructure platform that enables users to efficiently discover, access and process these massive volumes of data increases the impact of investments in collection of the data and catalyzes scientific discovery as well as informs critical decisions that are made across our Nation every day that depend on elevation data, ranging from immediate safety of life, property, and environment to long term planning for infrastructure projects.
Join us to hear about the motivations, technology, and data assets behind the National Science Foundation funded OpenTopography platform, which aims to democratize access to high resolution topographic data. OpenTopography’s innovation is in co-locating massive volumes of topographic data with processing tools that enable users with varied expertise and application domains to quickly and easily access and process data, to enable innovation and decision making.

Field Data Collecting, Processing and Sharing: Using web Service TechnologiesNiroshan Sanjaya
Collecting, Distributing and Analyzing field data is a crucial part in any geospatial study. Field data collection tools and methods have been developed significantly due to the advancement of technologies such as Global Navigational Satellite Systems (GNSS) and development of smartphones. Accurate field data collection is also a necessary task for broad spatial data analysis and proper decision making. Development of Web technologies led to share the data and information effectively. This study tries to develop a framework based on the Geospatial Semantic Web technologies for disseminating and processing field data. Experimental results from an implemented prototype show that the proposed framework allows to visualize and process the field data in any context. The system of this study is capable of distributing and processing field data using web application. Moreover, the study demonstrates the importance and the capabilities of web services for spatial data gathering and processing. The system has been developed based on Free and Open Source Software (FOSS) packages such as ZOO-Project, Open Data Kit, etc. It enables user to further improve or deploy the system for variety of studies.

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.

This document discusses using spatial data infrastructure (SDI) data to understand and link spatially referenced application data. It addresses the problem of "yet another portal" where many portals exist but cannot be easily integrated. The document proposes using linked data to index SDI resources and connect SDI and application data. This would allow finding metadata about specific spatial references across multiple datasets. It demonstrates this approach with a gazetteer for social protection in Indonesia and discusses goals of fundamentally improving information integration capabilities.

In the rapidly evolving landscape of technologies, XML continues to play a vital role in structuring, storing, and transporting data across diverse systems. The recent advancements in artificial intelligence (AI) present new methodologies for enhancing XML development workflows, introducing efficiency, automation, and intelligent capabilities. This presentation will outline the scope and perspective of utilizing AI in XML development. The potential benefits and the possible pitfalls will be highlighted, providing a balanced view of the subject.
We will explore the capabilities of AI in understanding XML markup languages and autonomously creating structured XML content. Additionally, we will examine the capacity of AI to enrich plain text with appropriate XML markup. Practical examples and methodological guidelines will be provided to elucidate how AI can be effectively prompted to interpret and generate accurate XML markup.
Further emphasis will be placed on the role of AI in developing XSLT, or schemas such as XSD and Schematron. We will address the techniques and strategies adopted to create prompts for generating code, explaining code, or refactoring the code, and the results achieved.
The discussion will extend to how AI can be used to transform XML content. In particular, the focus will be on the use of AI XPath extension functions in XSLT, Schematron, Schematron Quick Fixes, or for XML content refactoring.
The presentation aims to deliver a comprehensive overview of AI usage in XML development, providing attendees with the necessary knowledge to make informed decisions. Whether you’re at the early stages of adopting AI or considering integrating it in advanced XML development, this presentation will cover all levels of expertise.

OGC Services
Open Geospatial Consortium (OGC) - a non-profit,
international, voluntary standards organization, leading the
development of standards for geospatial services
OGC founded in August 1994 and includes a wide range
of vendor members, universities, state agencies and
federal agencies
Aim is to advance geo-processing interoperability across
the GIS industry
Web Map Services (WMS)
Web Feature Services (WFS)
Web Coverage Services (WCS)

What is Interoperability?
One does not have to adopt the same format to be interoperable!
Interoperability aims to adopt a negotiating system to understand a
wide range of formats e.g. WMS, WFS and WCS
‘one should actively be engaged in the ongoing process of ensuring
that the systems, procedures and culture of an organisation are
managed in such a way as to maximise opportunities for exchange
and re-use of information, whether internally or externally’
Paul Miller, University of Hull
At the SIDS WMS provide an alternative to the traditional download
area of the website and potential to exchange data with other
academic institutions
21. 13th December 2006 Development Activities - Data Access Infrastructure21
Justification
SIDS can better utilize the imagery in the archive
Increase visibility to an increasingly sophisticated user
community, reducing the need to contact the SIDS by
more traditional means e.g.
Telephone
In writing
Working on-line with traditional point and click download
interface
By the SIDS abiding by OGC specifications our service
can be an interoperable organization with others,
increasing the potential usability of the service.
The SIDS can still maintain our own unique branding
within the Portals through which the content is available
e.g. Customized Chameleon OGC Viewer.

Editor's Notes
A Web Map Service produces maps of spatially referenced data dynamically from geographic information. This International Standard defined a map to be a portrayal of geographic information as a digital image file suitable for display on a computer screen. A map is not the data itself. Rendered in a pictorial form such as PNG, GIF or JPEG. 3 operations – one returns service-level metadata GetCapabilities - returns a map whose geographic and dimensional parameters are well defined GetMap - optional third returns information about particular featured shown on a map GetFeatureInfo The OGC Web Feature Service allows a client to retrieve and update geospatial data encoded in Geography Markup Language (GML) from multiple Web Feature Services. The requirements for a Web Feature Service are: 1. The interfaces must be defined in XML. 2. GML must be used to express features within the interface. 3. At a minimum a WFS must be able to present features using GML. 4. The predicate or filter language will be defined in XML and be derived from CQL as defined in the OpenGIS Catalogue Interface Implementation Specification. 5. The datastore used to store geographic features should be opaque to client applications and their only view of the data should be through the WFS interface. 6. The use of a subset of XPath expressions for referencing properties The Web Coverage Service (WCS) supports electronic interchange of geospatial data as "coverages" – that is, digital geospatial information representing space-varying phenomena, allows clients to choose portions of a server's information holdings based on spatial constraints and other criteria. Unlike WMS which filters and portrays spatial data to return static maps (rendered as pictures by the server), the Web Coverage Service provides available data together with their detailed descriptions; allows complex queries against these data; and returns data with its original semantics (instead of pictures) which can be interpreted, extrapolated, etc. -- and not just portrayed. Unlike WFS which returns discrete geospatial features, the Web Coverage Service returns representations of space-varying phenomena that relate a spatio-temporal domain to a (possibly multidimensional) range of properties. Three operations: GetCapabilities, GetCoverage, and DescribeCoverage. The GetCapabilities operation returns an XML document de-scribing the service and brief descriptions of the data collections from which clients may request coverages. The DescribeCoverage operation lets clients request a full description of one or more coverages served by a particular WCS server. The server responds with an XML docu-ment that fully describes the identified coverages. The GetCoverage operation of a Web Coverage Service is normally run after GetCapa-bilities and DescribeCoverage replies have shown what requests are allowed and what data are available. The GetCoverage operation returns a coverage (that is, values or prop-erties of a set of geographic locations), bundled in a well-known coverage format. Its syntax and semantics bear some resemblance to the WMS GetMap and WFS GetFeature requests, but several extensions support the retrieval of coverages rather than static maps or discrete features. A Web Processing Service provides a client access across a network to pre-programmed calculations and computation models that operate on spatially reference data. The calcualtion can be extremely complex or simple with any number of data inputs and outputs. To achieve interoperability each process must be defined in a separate document ‘Application Profile’.
