Consistent means to share geographic data among all users could produce significant savings for data collection and use and enhance decision making. Executive Order 12906 calls for the establishment of the National Spatial Data Infrastructure (NSDI) defined as the technologies, policies, and people necessary to promote sharing of geospatial data throughout all levels of government, the private and non-profit sectors, and the academic community.

The goal of this Infrastructure is to reduce duplication of effort among agencies, improve quality and reduce costs related to geographic information, make geographic data more accessible to the public, increase the benefits of using available data, and establish key partnerships with states, counties, cities, tribal nations, academia and the private sector to increase data availability.

A panel of state, federal, academia and industry experts in spatial data will lead a free-wheeling discussion regarding survival in the spatial age with "data, data everywhere and yet not enough to think."

1. Hundreds of thousands of KML/SHP/etc. spatial data files are out there. How do you find the ones you want?

2. Computation-heavy data analysis is needed just to see climate data, much more do research with. How do you spread that computation load around?

3. Each local government entity throughout each state and across the nation are in need of similar data management tools, as well as access to similar datasets. How do we route ourselves away from duplicative GIS solutions and happily harness the larger community?

4. Given that natural disasters are an inevitable part of life on Earth, be they earthquakes, forest fires or storm activity, how do we optimize access to the considerable datasets (i.e., NetCDF) essential for weather forecasting, climate research and disaster management?

Please join us in brainstorming smarter ways for a precious planet to do business.



Leveraging Agile Development and Architecture Techniques in the Development of GeoInformatics Standards

Nadine Alameh, George Percivall

Wednesday May 25 9:00 AM - 10:30 AM

With the increasingly seamless integration of geospatial intelligence into mainstream IT solutions and the rise of the "Geospatial Web", the need for geoinformatics standards is ever more critical. Geoinformatics standards detail the engineering aspects (and rules) capturing common agreements for implementing an interface or encoding that applies to specific geospatial interoperability problems. Standards from organizations such as ISO and the Open Geospatial Consortium (OGC) enable users to more freely exchange and apply geospatial information, applications and services across networks, platforms and products.

This panel is about the emerging agile processes behind the development of such standards in the geoinformatics field, specifically complementing the traditional formal consensus processes as a way to keep up with rapid technology changes, and the immediate needs for these standards in a wide range of domains. Agile processes are based on iterative, incremental and collaborative development, and typically deliver increased value, higher adaptability and reduced risk levels in meeting customer requirements and project objectives.

As an example in the geospatial field, the OGC Interoperability Program organizes and manages Interoperability Initiatives based on a rapid engineering process to develop, test, demonstrate, and promote the use of OGC standards. Such initiatives typically provide the initial working prototypes that are positioned to be the next best standards. Complemented by a solid architecture framework, this process allows for the development of set of standards for adoption in mature products.

This panel hosts representatives from standards-development organizations and industry to provide their perspectives on the agile processes in geoinformatics standards development and their value to their members/customers in the era of ubiquitous geospatial informatics. Such agile processes contribute to achieving the guiding vision of a world in which everyone benefits from geographic information and services made available across any network, application, or platform.

The North American Datum of 1983 (NAD 83) witnessed over the past few decades major transformation in order to satisfy users need in terms of accuracy and reliability. Such transformation evolved in multi-phase modernization program that left users anxious about tools and procedures that they needed to implement in order to catch up with such changes. Today, users of NAD83 have to deal with different versions of the datum such as NAD83/86, NAD83/HARN, NAD83/CORS(96), and the latest adjustment of NAD83/NSRS2007. The subsequent versions added confusion and discrepancies in the product delivered over the years. The North American Vertical Datum of 1988 (NAVD88) went through similar evolution each time a new geoid model is published. The panel addresses users concerns and shed the light on the latest efforts lead by the National Geodetic Survey (NGS) to modernize the datums to coincide with the more reliable and globally maintained, the International Terrestrial Reference System (ITRS) realized by a set of reference points coordinates denoted by the International Terrestrial Reference Frame (ITRF).
