The wide availability of technologies such as GPS, map services and social networks, has resulted in the proliferation of geospatial data on the Web. Similarly, the amount of geospatial data extracted from the Web and published as Linked Data is increasing. Together with large volumes of machine-generated data from sensor networks and the emerging internet of things, these continually growing data have given rise to a number of innovative services and applications.

This workshop aims to provide an inter-disciplinary forum to explore and promote the technologies related to a combination of semantic web, geospatial web and sensor networking. Specifically, to develop an understanding of the ways semantic web technologies can contribute to the growth, integration and deployment of geospatial applications. As a joint workshop, it will explore both foundational technologies of the Semantic Geospatial Web and applications of semantic technologies to large-scale sensor networks and the emerging web of things. The workshop will bring together researchers and practitioners from various disciplines, as well as interested parties from industry and government, to advance the frontiers of these emerging research areas. This field continues to gain popularity, resulting in a need for a forum to discuss relevant issues.

We invite two kinds of submissions:

• Research papers. These should not exceed 12 pages in length.
• Demos. Deployed technologies are important if the Geospatial Web is to be realized. We therefore strongly encourage the submission of demos, and the presentation of demos related to research papers (a separate demo paper does not need to be submitted in this case, but the research paper should clearly discuss the demo to be presented). Demo papers should not exceed 5 pages in length.

Submissions should be formatted according to the Lecture Notes in Compute Science guidelines for proceedings available at http://www.springer.com/computer/lncs?SGWID=0-164-6-793341-0.

Papers should be submitted in PDF format using the Easy chair system: https://easychair.org/conferences/?conf=ssntc2015.

At least one author of each accepted paper or demo must register for the workshop. Information about registration can be found on the ISWC 2015 Web page: http://iswc2015.semanticweb.org/registration.

PLEASE NOTE: ISWC does not allow workshop-only registrations. To attend, you will need to register and pay for the workshop plus the conference. Last time, the workshop proceedings were published electronically in the CEUR series. We plan to do the same this year.
