Version 4.0 of the crowd mapping software Mark-a-Spot offers new Open-Data interfaces and flexible data visualization.

Mark-a-Spot is a free, internet-based software for reporting infrastructure problems, ideas and suggestions. It can be integrated directly into municipal internet portfolios by city administrations.

Numerous cities like Cologne and Bonn in Germany established the tool, which is an open and transparent public civic issue tracking software that provides a considerable image gain for the administration.

The involvement of the population sharpens authorities’ perception of the problem, and their efficiency is made more transparent.

Mark-a-Spot offers a transparent, centralized switching point with open and internationally standardized interfaces.

With the new version 4 of the tool, additional Open-Data resources extend the included Open311 server and offer dynamic data visualizations for internal or public real-time monitoring of the administration work.

Drupal 8 in the background

As a so-called Drupal distribution, Mark-a-Spot is easy to implement and expand. The software is published under the “GNU General Public Licence” and can be run and modified by every user free of charge.

Hosting in the Open-SaaS Model

With the offered hosting options starting at $ 99 monthly without a fixed contract period, cities and districts are not subject to any vendor lock-in: code and data are available to the administration at any time to operate the procedure in their own data center.

About this project

Mark-a-Spot is an open source software based on the Content Management Framework Drupal 8, which has been continuously developed on GitHub since 2011. It is used by various organizations such as city administrations (e. g. Cologne, Bonn, Ahaus, Annaberg-Buchholz), NGOs (World Bank) or newspapers (Süddeutsche Zeitung) to collect geo-based data.
