Geographic tools have emerged that use open-standards and support users creating and sharing their own geodata. Together, these tools form a GeoStack that enable the entire lifecycle of data. Publish Blogging tools, geotagged photographs, mobile devices, and geolocation enable people to capture and share their stories, travels, and news. Sites like Platial, Flickr, or Ning have also embraced open standards, allowing users to export and reuse their data. Transport GeoRSS, KML, and GPX are just some of the data format standards that can carry geographic information from provider to consumer. Aggregate Services such as Mapufacture mix and match feeds of data from their source to potential users. Keyword and geographic searches can provide useful collections from various sources. Consume Mapstraction, OpenLayers, GoogleEarth, and other geographic visualization libraries and tools make it possible to view and display various geographic information. In addition, it is possible to store user-created maps and points of interest to their mobile devices and GPS receivers for use when on the move. This talk will discuss the technologies that currently comprise the GeoStack and how it is enabling users to share and use geographic data. Developers can fit their tools into any point along this stack, or add to existing services. We'll also discuss the future of the geotools. O'Reilly Home |
