Logo Design

The FOSS4G 2018 Local Organizing Committee was pleased to announce a call for logo designs. We needed your help to build a strong recognizable logo for FOSS4G Dar es Salaam 2018.

Full details are available here: FOSS4G 2018/Logo Contest

We put together this Design Brief (borrowing from the FOSS4G 2017) that outlines what we are looking for in a logo. Entrants could be an individual or team of people, even a design company.

By submitting a logo you will be assigning your copyright to OSGeo so that it can be used across different mediums. The LOC may also commission improvements of the winning work. Entries need to appear on the wiki page FOSS4G 2018/Logo Entries by 23:59 EAT (before midnight) on Friday, April 15th, 2017. The FOSS4G 2018 Local Organizing Committee will decide by vote which logo to use.

How to enter

  • Create your logo in PNG file format and a scalable file format (either SVG or PDF).
    • If you're not used to scalable formats please still enter the competition as we can try to help.
  • Make your logo available online, one option is to upload it to the OSM Wiki (upload link).
  • Add a link, or include your logo on the wiki page FOSS4G 2018/Logo Entries.


The FOSS4G website (, flyers, emails, sponsor communications, t-shirts and potentially other conference ‘schwag’ like fabric or plastic bags, keychains, pens etc. Printed material at the conference such as timetable of talks, notebooks, banners and conference guide. Potentially small web-based button images for use on third party websites to promote the conference or fact that someone is speaking there, for placement on blogs and other web pages.


The design MUST

  • Include elements of the OSGeo / FOSS4G "ribbon" as can be seen in all previous conference logos OSGeo-Ribbon.jpg File:FOSS4G ribbon.pdf
  • Include themes for Tanzania
  • Be easily printable on t-shirts with as few colours as possible (no more than 3). This keeps the cost of printing down.
  • Be delivered in PNG file format and a scalable format (SVG or PDF).
  • Not be similar to other mapping conference logos (Where 2.0, ESRI, SOTM...)
  • Not communicate the brand of potential sponsors or related companies
  • Not include copyrighted material that is not yours

The design MAY

  • Come in different sizes (example: a main logo and a variant for use on small print media such as badges).

  • The Africa Experience
  • Fun
  • Nature
  • Cool
  • Openness
  • A sense of community
  • The potential of free and open source geospatial tools
  • A sense of learning and education
  • Intelligence
  • Trustworthiness
  • Global movement

The design should not communicate

  • Corporate / big business (as the sole element)
  • Complexity
  • Expensive
