Missing Maps Data Collection and Validation Mapathon to help eliminate Malaria

Malaria is a major threat to people all around the world, particularly those most vulnerable: children and elderly. Our previous events Semester Start Missing Maps mapathon for World Malaria Day 2017 and Missing Maps Mapathon at Makerspace (DAI) aimed to support projects to identify potential malaria affected areas and enable better Malaria prevention in collaboration with Clinton Health Access Initiative (CHAI), Humanitarian OpenStreetMap Team and Missing Maps.

How? Means to combat Malaria are provided by creating openly available map data. We do our part by providing and assessing basic map data to support the current Malaria initiatives and our common goal, to support those in need.

Therefore, disastermappers heidelberg and HeiGIT/GIScience Research Group invite you to a Missing Maps Mapathon! In contrast to previous events, this time you will not only learn about OSM and how to contribute, but also get familiar with OSM data validation.

Why?  The value of OSM data increases when it is reviewed and lessons learned are ultimately applied. Accurate maps can then help to decrease uncertainties and enable confident use of the data by the field teams that need data to fight the spread of malaria.

When?     Wednesday 05.07.2017, 6 pm

Where?     Großer Hörsaal, Geographisches Institut, Berliner Straße 48

We will provide an introduction to OpenStreetMap mapping. Additionally, an introduction into validation of OpenStreetMap data in the Tasking Manager is offered via Skype by one of the main validators of HOT/ Missing Maps London.

Therefore, no previous knowledge is necessary. Just bring your own laptop and mouse if available.

Snacks and drinks will for sure be provided! And guess what: to round up the  Mapathon we will moreover fire up the BBQ for you! Therefore make sure to bring your ribs or veggies along 🙂


Mapathon – Help to analyze Open Street Map land use quality

Knowledge of land use dynamics is essential for a permanent human existence on earth, for instance due to changing climate. Various commercial and scientific products depicting our habitat exist, involving heavy production cost, questionable accuracies and inadequate update cycles. To this end, utilized Open Street Map (OSM) to generate planetary available land use data.

However a map is not completed until its accuracy was assessed. Here, our colleagues from the GIScience Research Group happily invite you to a validation Mapathon of OSM land use data to elevate its use for greater purpose. Activity involves inspection of remote sensing data and estimation of land use.

When: Thursday, 29.06.2017, 6 pm
Where: PC-labs, Berliner Straße 48, Heidelberg

Bring along:

  • yourself
  • computers are provided, usage of own laptop is encouraged
  • snacks and drinks are provided


New Disaster OpenRouteService release

Recently our HeiGIT team @ GIScience (Heidelberg University) developed a new disaster version of OpenRouteService (ORS) to support humanitarian logistics and to enable making use of OSM data for disaster routing purposes in a more sustainable way.

Since 2008, the OpenRouteService had been applied for specific disaster cases for Haiti in 2008 and 2010, Nepal in 2015 and Ecuador in 2016.

In order to provide this tool in a permanent manner and with most recent data, the routing and disaster mapping team at HeiGIT jointly developed this new dedicated disaster ORS:

Besides the ability to navigate on daily updated OSM data, our service provides an accessibility analysis service, an interactive avoid area tool, and allows the export of GPS tracks. In addition to the usage via the web application the API endpoint can also be integrated in dedicated applications (e.g. QGIS Plugins) etc.
