Poster and Demo Instructions

The Demo&Poster session is a good opportunity for the authors of Poster papers and Demonstration papers to showcase their work and meet with interested attendees for in-depth technical discussions. Thus it is important that you shape your work in an attractive way and keep your message clear and noticeable to attract people who might have an interest in your work. Please carefully follow the instructions below. Remark: In contrast to previous editions of the conference, this year, the SRC posters will be presented during the workshop day.

  1. Poster Preparation: All the Poster and Demo papers should prepare a poster to be displayed during the Demo&Poster Session (see program at

    Note: The poster presentation is mandatory. Papers without a poster presented during the Poster&Demo reception (resp. the SRC poster session) will be removed from the conference proceedings.

    The size of your poster should be no more than 36 inches wide and 48 inches tall, and in portrait orientation. We will provide you with a backing board of this size along with binder clips to hold the posters to it. Please do not make a poster larger than the recommended size.

    The title of your poster should appear at the top in CAPITAL letters about 25mm high. On the left of the Title put your Poster ID or your Demo ID according to the list at the end of this document; Below the title put the author(s)' name(s) and affiliation(s).

    The flow of your poster should be from the top left to the bottom right. Use arrows to lead your viewer through the poster. Use color for highlighting and to make your poster more attractive. Use pictures, diagrams, cartoons, figures, etc., rather than text wherever possible. Try to state your main result in 6 lines or less, in lettering about 15mm high so that people can read the poster from a distance. The smallest text on your poster should be at least 9mm high, and the important points should be in a larger size. Use a sans-serif font (such as "cmss" in the Computer Modern family or the "Helvetica" PostScript font) to make the print easier to read from a distance.

    Make your poster as self-explanatory as possible. This will save your efforts for technical discussions. You may bring additional audio or visual aids to enhance your presentation. In order to help you interact with the people who attend the session, we suggest you to prepare a short talk of 2 to 5 minutes to introduce your work to viewers.

  2. Demo Preparation: Only Demo paper authors need to prepare a demo in addition to the poster.

    The presenter should bring their own laptops. Wireless Internet will be available throughout the conference venue. We will try to provide demo paper authors with access to electrical outlets, but please prepare for the scenario where they may not be available to you. The presenter should prepare a demonstration of your system that you can periodically give to those assembled around your table throughout the reception. If possible, co-authors should attend the session to aid in discussions, and to provide the presenters with the chance to rest or briefly view other demos and posters.

  3. Prepare Fast Forward Preview Slides.

    Authors of each Poster paper should also prepare a 3-slide presentation to give a quick overview of their poster during the “Fast-Forward Preview” session (earlier than the Poster&Demo reception session, see program at The entire session will last 1 hour 30 minutes. Each poster paper will have exactly two minutes to give the audience an overview of your poster. The Fast-forward Preview slides should be sent to the Poster Chair email address ( no later than [11:59PM, October 26, 2018].

    Poster papers without fast-forward slides submitted will be removed from the conference proceedings.

    Detailed instructions: Please prepare your presentation in Microsoft PowerPoint. Your presentation should consist of three slides -- one slide with the Poster ID, title of the paper, names of authors and affiliations (title slide) and two slides on the content of your work (content slides). You are encouraged to include pictures, screen shots, animations, and movies in your presentation.

    Please make your slides "self running" and timed so that they last EXACTLY TWO MINUTES. The title slide should be allocated a minimum of 10 seconds, so that you have enough time to walk to the podium (and also for the preceding presenting author to leave the podium). Please divide the remaining time (one minute and fifty seconds) between the content slides.

    All the slides from every poster paper will be put together into a master presentation. The master presentation will be "self running". This means that you will not have any control over the progression of the slides, which will occur entirely automatically. Therefore, please rehearse and set the transition times accordingly. As well be prepared if you start with a sometimes inevitable delay of no more than 5-10 seconds due to whatever reason before you can start.

  4. Poster and Demo Awards

    In order to encourage the authors of poster and demo papers to participate the conference and introduce their work, the ACM SIGSPATIAL GIS organizing committee has instituted three awards for the poster and demo authors, which will be honored during the banquet.

    • Best Fast Forward Preview Presentation: The best 2-minute presentation given during the fast-forward preview session ("best" from a visual and attention grabbing standpoint in addition to the scientific value).
    • Best Poster: The best actual Poster presented during the Poster&Demo Reception ("best" including an aesthetic sense).
    • Best Demo: The best Demo presented during the Poster&Demo Reception.

Please contact the Poster Co-Chairs if you have any questions.
