GeoRSS, GPX and MIDAS Plug-ins for Cadcorp SIS will enable GIS users to incorporate specialised geographically-referenced data.    Press Release, Stevenage, 15 Jun 2006

Digital mapping and geographic information systems (GIS) software developer Cadcorp has announced that it is offering three new Plug-ins for XML-based data for use with its Cadcorp SIS – Spatial Information System software suite.

The GeoRSS, GPX and MIDAS Plug-ins are part of V6.3 of Cadcorp SIS, due later this year, but are fully compatible with the current V6.2 release. The new Plug-ins will be available for free download from the Cadcorp web site.

The next service pack release of Cadcorp SIS V6.2 will include a version of the free Map Browser product that will be able to use the GeoRSS Plug-in. This will enable Map Browser users to load GeoRSS ‘feeds’ and to combine them with Open Geospatial Consortium, Inc.™ (OGC™) W*S services.

“GeoRSS, although a relatively recent development, is rapidly becoming the format of choice for ‘geotagging’ everything from earthquake locations to mountain bike trails” said Martin Daly, technical director, Cadcorp. “These new Plug-ins for XML-based data – each with very different contents aimed at very different groups of users - will allow the Cadcorp SIS user to easily overlay and correlate the information with their own data in a wide variety of use cases.”

GeoRSS Plug-in

Really Simple Syndication (RSS), a family of XML formats for exchanging news, particularly about web pages or other web content, is used by many dynamic web sites, e.g. news sites, ‘blogs’, etc., to provide ‘feeds’ of their new or changed content. These feeds typically contain only basic information, such as author, date, title and brief description, enabling the reader, or an RSS aggregator service, to decide which materials are worth further investigation.

GeoRSS, which is supported by the OGC, is a simple extension to RSS feeds to describe the location of the information in geographic coordinates. As RSS becomes more prevalent as a means of publishing and sharing information, GeoRSS is expected to become increasingly important in enabling applications to request, aggregate, and share geographically tagged feeds.

“GeoRSS changes the dynamics between GIS and mainstream IT. I expect those two worlds to really begin to merge now,” said Raj Singh, Director of Interoperability Programs, OGC. “It's exciting to see a company as committed to interoperability as Cadcorp leading the way in this brave new world.”

Using GeoRSS, a local authority could make feeds of planned and actual street works available through its web site, enabling other organisations involved in street works, such as utility companies, to obtain up-to-date information on the location of new road openings. Also, estate agents will be able to use GeoRSS feeds to allow prospective buyers to keep up to date with new properties for sale, of a particular value, and in a given area.

GPX Plug-in

Designed from the ground up to be the standard XML format for exchanging GPS data, the GPX (Global Positioning eXchange) format encodes GPS data (waypoints, routes, tracks) and enables the data to be shared between software programs and between web services. The GPX Plug-in will allow Cadcorp SIS users to read GPX data exported from third party GPS software without conversion or translation.


Developed under the auspices of English Heritage to support interoperability for the UK’s Historic Environment Information Resources (HEIRs), MIDAS XML is a set of World Wide Web Consortium (W3C)-compliant XML schemas that cover specific information categories, such as monuments, events (e.g. investigations), people and spatial data etc., relating to the UK’s national historic environment.

Using the Cadcorp SIS MIDAS XML Plug-in, historic information users such as local authorities (who receive listed-building data from English Heritage in MIDAS XML format), university-based research projects, professional heritage managers and national thematic study groups, etc., will be able to access, share and make best use of the vast quantity of historic environment information maintained by a wide variety of national bodies of record.
