OGC standards relevant to ISPRS
Presentation to for the ISPRS Congress 2012, Melbourne
Over the last decade, standards have played a key role in the expansion of the market for Earth Observation (EO) products and services. Standards become increasingly important as geospatial technologies and markets continue to evolve in an increasingly complex technology ecosystem. OGC and ISPRS work jointly to further the development of this vital information industry.
We continue to see global growth in the supply of geometrically controlled image-based geodata. On the data supplier side, most end-use EO information products use data from multiple EO sources (aerial and satellite) as well as from ground-based sources. On the customer side, customers’ business models involving EO data require easy connections between multiple data suppliers and multiple technology platforms. Typically, new markets create stovepiped, proprietary solutions that persist until market forces create demand for standards that in turn enhance market opportunity. The OGC’s standards meet this demand in the geospatial markets.
OGC leads worldwide in the creation and establishment of standards that allow geospatial content and services to be seamlessly integrated into business and civic processes, the spatial web and enterprise computing. OGC accelerates market assimilation of interoperability research through collaborative consortium processes.
OGC has both domain focused and technology focused activities. For example, the Meteorology & Oceanography Domain Working Group ensures that OGC standards and profiles allow the meteorological community to develop effective interoperability for web services and content across the wider geospatial domain. These needs are met for example by the technology of standards such as netCDF which was brought into the OGC to encourage broader international use and greater interoperability among clients and servers interchanging data in binary form.
Most OGC standards specify open interfaces or encodings that apply to imagery. Some of these are:
o Web Coverage Service (WCS)
o Web Coverage Processing Service (WCPS)
o Web Map Service (WMS)
o Geography Markup Language (GML)
o GML in JPEG 2000 Encoding
o OGC Network Common Data Form (NetCDF)
o Sensor Observation Service (SOS)
o Sensor Planning Service (SPS)
o Sensor Model Language Encoding Standard (SensorML).
o Catalogue Service for the WEB (CSW)

Artificial Intelligence for XMLDevelopment
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.
By highlighting the potential advantages and challenges of integrating AI with XML development tools and languages, the presentation seeks to inspire thoughtful conversation around the future of XML development. We’ll not only delve into the technical aspects of AI-powered XML development but also discuss practical implications and possible future directions.
Removing Uninteresting Bytes in Software Fuzzing
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.
