DATAMAP INTELLIGENCE is the sole provider of this exclusive geo-demographic data. Learn more by visiting www.datamapintel.com
Editor's Note: OGC has been remarkably successful.Today, the Web is the dominant distributed computing platform, and OGC's OpenGIS® Specifications for interfaces (like the OpenGIS Web Map Server Specification) and XML Schemas (like the Geography Markup Language) are the foundation for the "Spatial Web." Just as all Web sites must implement html, all Web sites serving spatial data or spatial processing services must implement OpenGIS Specifications if they are to be part of the open Spatial Web.It begins with simple Web mapping: Today there are many sites offering automatic overlay of maps portraying data from multiple different servers on other sites.Every major vendors' map servers and map viewing clients support this.Simple Web mapping leads to OGC Web Services, which comprise the geoprocessing layer of the Web Services architecture being developed by W3C and other consortia.In a few years, the network will be your computer and the geoprocessing software services you need will be provided by a variety of servers on the Web.

OGC's Mandate

The OGC, the Internet Engineering Task Force (IETF) and the World Wide Web Consortium (W3C) exemplify the best in information technology standard setting.They run open consensus processes to create specifications that enable global communication between software systems.The processes at work in these organizations are designed to avoid domination by any single vendor, community, or country.Competitors work toward consensus in these organizations to build an infrastructure that serves them all and that serves their users.

No doubt, each of the biggest vendors in our market would love to "set the standard" and provide the kind of interoperability through market domination that Microsoft has provided for the past 15 years in the area of operating systems.But after two or three decades of competition, none of these GIS vendors has achieved the 80% market share necessary to squeeze out all competitors by exploiting their user's need to share information with other users.Unfortunately for everyone, as a result of "hyper-competition," the market has been stunted by users' difficulties in sharing spatial information and integrating spatial information into other applications.But over time, each vendor came to see that the best way to get a bigger piece of pie was to, yes, continue the struggle for market share, but also to expand the pie, that is, to join OGC to enable the market to grow.Standards help markets grow because they make it cheaper, easier and more worthwhile for customers to get into the game, so the overall number of customers increases. We see that happening now in the geospatial technology market.

For smaller vendors, standards are particularly beneficial.Every small vendor aims to provide some special features and benefits that are lacking in the larger vendors' products, and most small vendors can't support the full range of features offered by the larger vendors.Many small vendors thus tie their fortunes to a large vendor's fortunes by becoming "third party" or "complementary product" developers.In some cases, and certainly in the case of OpenGIS Specifications, standards enable such developers to become third party developers to multiple larger partners, with little or no requirement to maintain a separate set of software interfaces for each partner, and with less requirement to maintain close technology or business ties to the larger vendor.

Standards are also beneficial to integrators.Integrators who build solutions using one major software suite often see that pieces from another vendor's software suite would best meet their client's needs, but the lack of open interfaces makes a multi-vendor solution impractical.Those bad old days are gone.With open interfaces, vendors can bring together "best-of-breed" components and provide clients with better, less expensive solutions.They can also "wrap" legacy systems with interfaces to make them part of the new solution and extend their useful lifetime.

OGC's mandate is strengthened by evolution in procurement policies. Governments around the world want to 1) create opportunities for "SMEs" (small and medium sized enterprises), 2) reduce their IT costs and 3) improve cross-jurisdictional information sharing.They also want to spur innovation, which advances when vendors compete and which stalls when many users can't buy something new because they are locked in to an old system.In Canada, open, neutral, interoperability standards enable Federal departments to cost effectively and efficiently carry out their geospatial mandates.GeoConnections/NRCan has endorsed OpenGIS Specifications for use in development of the Canadian Geospatial Data Infrastructure.In the US, the new Federal Enterprise Architecture (FEA) that has been developed and is being promoted by the Office of Management and Budget (OMB) and also the OMB Circular A-119, "Federal Participation in the Development and Use of Voluntary Consensus Standards and in Conformity Assessment Activities" support the much older Executive Order 12906, which calls for the establishment of the National Spatial Data Infrastructure.

The concentrated mixing of technical talent and user perspectives in OGC meetings definitely advances innovation.Specifications in new areas like Sensor Web Enablement [http://ip.opengis.org/ows2/] and Open Location Services open wonderful opportunities for innovative products.Very important to the developers of these products is the fact that the standards platform is non-proprietary and it is positioned to become global.

For some years, telephone calls have been placed between people in any two countries, railroad cars have rolled between countries on standard tracks, and car owners in every country have been buying tires that fit their foreign cars.Now, finally, GIS and remote sensing software vendors are making it possible for people to easily find, access and process digital geospatial data.The process by which this happens in OGC is rewarding in many ways, and I encourage you to get your organization involved.

“Neogeographic” Approach to Inexpensive Oil Spill Mapping

The Deepwater Horizon oil disaster in the Gulf of Mexico was an opportunity for a small group of geospatial activists promoting crowd-sourced information to apply low-cost mapping techniques. By taking a neogeographic approach to aerial imaging with consumer-off-the-shelf hardware and software, open source GIS, and crowd-sourced field mapping techniques, they regularly produced maps of a variety of oil-affected sites without great cost. They collected data using balloons and kites and small digital cameras, and mapped and shared the information with local organizations. You’ll find the author’s approach well suited to crisis mapping.

Podcast: Do We Need Maps in our Location-based Apps?

A reader posed the question that we articulate this way: "Why are data taken for granted in LBS hype? What happens when you remove the map?" Our editors think that is a great question and explore it in the context of navigation apps, weather and traffic apps, social apps and augmented reality.

The Convergence of Web and Desktop GIS

Tile server technologies and new alliances work to blur the lines between Web and desktop applications, which PBBI's Jon Winslow believes is good news for everyone. "Now GIS professionals can continue to perform [their] advanced data-driven analysis while seamlessly presenting this information using visual tools that are familiar to the broader business community." Winslow backs up his optimistic point of view in this article.

Introduction to Road Data - Part One

In part one of this article, Steve Jones, independent GIS logistics consultant, focuses on the core map data used for routing, something more and more organizations are doing in-house. This installment covers road network accuracy, network connectivity and road speeds, hierarchical routing, and road classification.

Podcast: Are GIS Pros Choosing Esri Community Maps over OpenStreetMap?

This month's State of the Map US, an OpenStreetMap event in Atlanta, teamed with mappers, but not so many GIS professionals. A webinar on Esri's Community Maps program hosted by Directions drew 800+ "live" attendees just last week. Why are mappers and GIS pros choosing to give their data to one project or the other and what are the implications?

State of the Map U.S. Conference Report

Last weekend Atlanta, Georgia hosted the State of the Map US conference, which focused on OpenStreetMap in the 50 states. Learon Dalby, GIS program manager for the Arkansas Geographic Information Office (AGIO), attended and shared this report. Among his observations: “The participants were from across the U.S., but typical GIS users were not in the majority.”

How Will You Answer the GeoCloud Computing Call?

What if your IT manager walked into your office and let you know it was time to move your geospatial operation into the cloud? What would you do? Where would you start? Do you even know what questions to ask? Our editors assess the state of the geocloud and offer some advice on how to prepare for what may be that inevitable knock on the door.
