Cloud computing, the prevailing and rapidly emerging technology, has become mainstream in most of the industries. Developed by the Information Center, Ministry of The Interior, Taiwan Geospatial One-Stop (TGOS) is the portal which enables users to search, view, query, and access the geospatial data and the web services in Taiwan.
Serving as the geodatabase and web service provider, TGOS contains comprehensive query catalog, Metadata database of national spatial data, and web services, helping government, organizations, academic institutions, and citizens to find information like contents, data providers (departments), and usage limits of the required geodata through searching Metadata on TGOS.
The public spatial data in Taiwan are owned by different departments. To effectively lower the cost of repeated service maintenance of the systems for government institutes, TGOS Cloud is developed to collect, store, and process the spatial data from local governments and then publish diverse APIs such as TGOS MAP API to integrate with their own data.
The existing TGOS only served to collect spatial data and offer physical files. In response to the recent expansion of system requirements, TGOS Cloud aims to fully support the original systems, to demonstrate the functionality such as membership database, browsing authority of spatial data, and service registration management, and to enable users to integrate the spatial data that will be processed and served as APIs on the TGOS portal.
In this project, SuperGIS Server 3 allows TGOS users to create, manage and distribute spatial data as GIS services including map services, feature services, and OGC services and unify map tile types to reduce labor cost in data preparation for government departments. Moreover, the server GIS ensures that new GIS services can be overlaid with the existing ones and easily applied to various mobile applications using Map API.
TGOS MAP API is classified into five elements, including the basic and advanced Web-controllers, stacking for map elements, data structures, and other located services. Users can use frequently-used essential base maps and manipulation tools to display the map data.
TGOS Cloud provides end-users with the ability to query data or employ application with pre-generated base maps. By accessing the TGOS Cloud system for TGOS MAP API and Network Service, users can develop their own map services using TGOS MAP API and achieve seamless data fusion in TGOS database for Web GIS and Mobile GIS applications.
With the development of TGOS Cloud, it facilitates organizations to integrate and publish spatial data as diverse services via connecting with TGOS services. Consequently, users are not only able to apply Map API offered by TGOS Cloud to conduct various analyses such as route analysis and buffer analysis but also to effectively manage their map websites without paying huge costs to publish maps.

The GeoTrellis team is very excited to announce the availability of GeoTrellis 0.8 (codename “Atlantis”), which is a major new release that is a huge step forward towards our goal of a general purpose, high performance geoprocessing library and runtime designed to perform and scale for the web.
As you delve into GeoTrellis 0.8 in more depth, here are some new features you may want to explore:

OpenGeo has recently released OpenGeo Suite 3.0. Slashgeo sat down with Rolando Peñate, the Product Manager for the OpenGeo Suite, to discuss this new release. Here are the results of our interview:
Slashgeo: What are some of the most exciting features available in the OpenGeo Suite 3.0 release?
Rolando: We’re most excited about bringing spatial processing to the OpenGeo Suite. With processing, our customers can work with larger data and perform just-in-time analysis with fewer bottlenecks than with a desktop-based GIS workflow. We believe that exposing processing on the web will provide IT professionals the flexibility to solve unique problems in innovative ways—either by directly invoking existing WPS processes, writing new processes in common scripting languages, using rendering transformations to style data, or even in ways we haven’t yet considered.
One place we’ve implemented this is a prototype for the USGS National Hydrography Dataset that allows editing of data while validating against strict topology rules across multiple layers. Their current tools require up to six hours for a single edit, but our prototype drastically reduced the effort—down to about one minute—by using a web-based editor.
We are also working to make processing operations easier in browser-based visualizations. Rendering transformations enable just-in-time use of any WPS process as part of a layer’s style. The process is applied on-the-fly to transform the area being viewed, rather than the full data set (as it would with desktop based GIS), and provide immediate visual feedback. For example, NASA’s Global Learning and Observations to Benefit the Environment (GLOBE) program leverages this feature for fast, dynamic presentation of interpolated surfaces derived from environmental measurements collected at schools around the world. Similarly, one could create topography maps in real-time by applying a process to a digital elevation model and defining a style for the resulting contour lines.
Slashgeo: How does OpenGeo Suite 3.0 measure up to comparable proprietary solutions?
Rolando: One of our goals for the OpenGeo Suite is to solve many of the same problems as proprietary solutions, though not necessarily by providing the same tools. Our product and proprietary solutions can both publish data from a variety of enterprise databases, including Oracle Spatial and Microsoft SQL Server. Both offer web services for querying and editing features, publishing and caching map tiles, and running processes on spatial data. Both provide tools for building web mapping applications or mobile applications.
The primary differences are in approach. While proprietary solutions use server-client architecture that’s been adapted to accommodate web services, the OpenGeo Suite was built for the web from the ground up and encompasses best practices from the IT field. Rather than build a kitchen sink product with many highly-specialized features, we focus on developing a powerful base of functionality and providing tools for building applications to solve specific problems. While traditional GIS requires ‘certified’ experts with extensive training to pull data into expensive desktop tools and provide derivative data, the OpenGeo Suite exposes similarly powerful functionality on the web in ways that are integrated with the tools that IT professionals use every day.
Slashgeo: How does cloud computing factor into OpenGeo’s plans for the future?
Rolando: Many of our customers already use our software in the cloud and we offer support for those who wish to deploy OpenGeo Suite on Amazon Web Services (AWS). As cloud computing steadily gains acceptance, we will continue to ensure that our products are reliable and scalable. We’re keen to expand these offerings so stay tuned and we’ll make sure to keep you updated on what we expect to do in the future.
Slashgeo: What major trends in the geospatial technology arena do you see developing in the next 5 years, and how will those trends impact OpenGeo?
Rolando: Much like how source code is managed with distributed version control, we anticipate a future where spatial data will live in a collaborative infrastructure that is able to track data’s origin and evolution. Although spatial data is really just one aspect of the greater information technology landscape for any given enterprise, it has traditionally been siloed and forced through specialized workflows. As with other types of ‘big data’, we foresee increased difficulty storing, managing, and maintaining spatial data across enterprises. Thanks in large part to the reactions to geospatial crowd-sourcing efforts like OpenStreetMap and Ushahidi, we see a significant shift in how geospatial data is conceived of, stored, and distributed.
Adopting the distributed version control model pioneered with source code will play a critical role in alleviating the difficulties that have historically plagued users of geospatial data. A distributed version control model can better address such problems as collaborating between users or organizations, maintaining authoritative data, and enabling offline, low-bandwidth, or intermittent connectivity. Just as access to source code enables a developer to change software by adding to or changing its functionality and appearance, access to underlying geospatial data enables cartographers and analysts to fix mistakes, conduct analysis and modeling, and update datasets. We foresee true collaboration around geospatial information having profound implications for users of geospatial data and have begun investing in solutions to support them.
Slashgeo: Is OpenGeo an example of a successful business model built around open source software? If so, what can other organizations learn from this business model?
Rolando: Given how much we’ve grown in the last several years we believe that a business built around open source software can not only succeed, but thrive. The appetite for open source software is growing; companies like RedHat and JBoss have proven that an open source development model does not inhibit growth, but can often enable it.
In a recent presentation at the Texas GIS forum, Paul Ramsey delivered a compelling introduction to open source and why it’s being adopted faster than ever. Among the many takeaways was the simple fact that startups love open source. Why? Because startups cannot afford artificial limits on their growth. While the cost of computing hardware falls every year, the cost of proprietary software licenses does not. If you’re using software licensed per CPU or core, the primary driver of scaling cost is software cost, and that math does not benefit the consumer. Larger enterprises are being strangled by the immense license costs they are being forced to pay year-over-year. Today we’re all expected to do more with less. With open source functionality meeting or exceeding proprietary solutions, license costs are quickly being targeted as an obvious way to cut costs.
While open source software lacks explicit license costs, all software has maintenance, operating and other related costs. Unsupported open source software shifts these costs to the end user, which isn’t an issue if the end user or their enterprise has expertise in the relevant software and is willing to pay for support using staff time. Commercial open source provides the option to save time and reduce direct labor costs by outsourcing maintenance and support to experts. OpenGeo steps in when enterprises lack the time, resources, or internal expertise to maintain open source software. OpenGeo’s mission is to lower costs while continually enhancing the functionality of open source, and our customers value that highly. We expand on these idea in our white paper, “The Value of the OpenGeo Suite”, which outlines our model and why it’s beneficial to all parties involved.
We appreciate the participation of OpenGeo, and of Rolando, in this interview. We hope you enjoyed reading it.

Cambridge, UK, 7th March 2012. Andrew Zolnai, an expert in GIS, has utilised Socium’s Online Validation Service (OVS) to automate the quality assurance process in his Medieval Fenlands wealth analysis project.
The Medieval Fenlands Data is made up of base Ordnance Survey data and associated attribute information with the latter being populated through a manual process. To ensure the validity of the information being produced and therefore its value, a full data validation and correction process was required.
Andrew’s option for this validation was a manual inspection until learning about Socium’s OVS. By utilising a combination of standard rulesets and working with Socium to build specific validation rules, Andrew was able to automate the entire data validation process. This not only ensured the accuracy of the resulting changing wealth demographics, but as the OVS is cloud based there were no capex or infrastructure costs, a key aspect to Andrew when working within a limited budget.
The automation that the OVS provided Andrew meant that what would have been a lengthy quality assurance process was a simple and extremely time efficient activity. It also enabled Andrew to confidently publish his results on a number of online data sites.
Andrew Zolnai commented:
“Having been in this business for decades, I cannot see how data validation can be made any easier, while maintaining - indeed increasing - data integrity. I would highly rate the Online Validation Service and recommend other users of spatial data to get online and try the service out. If you have an issue or problem you are working with in a particular dataset, I would suggest getting in touch with them to see what rules they can create to help you overcome it.”
Duncan Guthrie, Managing Director, Socium said:
“We were delighted to work with Andrew to create the rules he needed to validate the data in his Medieval Fenlands GIS project. We offer the service of rule creation to all of our users and are very happy to hear about and help them with the many different challenges that they face with their spatial data. By creating the rules and adding them into the service, we are always making sure that our users are getting the best value and benefit from the service and would encourage anyone to get in touch with us that has a data challenge so that we can provide something that will quickly and easily be able to help them overcome it.”
