Internationale Wochen gegen Rassismus

(for English, see below)

Hallo liebe disastermappers-Freund*innen!

Momentan laufen die Heidelberger Internationale Wochen gegen Rassismus 2021 – und auch wir sind dabei! Warum? Die ungleiche Verteilung von Ressourcen ist oft eine Konsequenz von historischem (und neo-) Kolonialismus und damit verbundenem Rassismus. Dies erhöht die Verwundbarkeit von Gesellschaften vieler Erdteile bei von Menschen und von der Natur verursachten Katastrophen. Was auch keine Überraschung sein sollte: in solchen Gegenden fehlt es meistens an gutem Kartenmaterial, was die Einsätze von Hilfsorganisationen sehr erschwert.

Wir tragen mit unserem Mapathon “Kartografierung für Internationale Solidarität” am 06.04 um 18:30 Uhr dazu bei, wichtige Kartendaten zu erheben.

Der Mapathon – ein Werkzeug der humanitären Kartografie – unterstützt präventive Maßnahmen und lebensrettende Einsätze. Mehrere Personen kommen (real oder virtuell) zusammen, um ein Krisengebiet zu kartografieren. Anhand von Satellitenbildern und einfach erlernbarer Computerprogramme, können Freiwillige dann in kurzer Zeit durch ihren Einsatz eine betroffene Gegend “auf die Karte” bringen und dies über das Internet den Helfer*innen vor Ort zur Verfügung stellen.

Zur Teilnahme reicht ein Tisch- bzw. Laptoprechner, eine Maus und Internetverbindung. Vorkenntnisse benötigt ihr keine, denn wir unterstützen Anfänger*innen mit ausführlichen Erklärungen auf Deutsch und Englisch – ihr seid also alle herzlich willkommen!

Beitreten könnt ihr der Veranstaltung mit diesem Link und dem folgenden Zugangscode: dove ultra tweak sanded oaf.

Weitere Informationen zu den Veranstaltungen der Internationalen Wochen gegen Rassismus findet ihr auch hier:

Wir freuen uns total auf euch und darauf, mit euch ein Zeichen gegen Rassismus und für globale Gerechtigkeit zu setzen!

Hello dear friends of the disastermappers!

At the moment, the Heidelberg International Weeks against Racism 2021 are running – and we are also taking part! Why? The unequal distribution of resources is often a consequence of historical (and neo-) colonialism and related racism. This increases the vulnerability of societies in many parts of the world to man-made and natural disasters. What should also come as no surprise: in such areas, there is usually a lack of good maps, which makes it very difficult for aid organisations to intervene.

We are contributing to the collection of important map data with our Mapathon “Mapping for International Solidarity” on 06.04 at 18:30.

The Mapathon – a tool of humanitarian cartography – supports preventive measures and life-saving missions. Several people come together (real or virtual) to map a crisis area. Using satellite images and easy-to-learn computer programmes, volunteers can then quickly put an affected area “on the map” through their efforts and make this available to aid workers on the ground via the internet.

All you need to participate is a desktop or laptop computer, a mouse and an internet connection. You don’t need any previous knowledge, because we support beginners with detailed explanations in German and English – so you are all welcome!

You can join the event with this link and the following access code: dove ultra tweak sanded oaf.

We are really looking forward to meeting you and making a statement against racism and for global justice!

International Mapathon

Dear mappers,

On December 8th at 6.30 pm our next international mapathon takes place! This time we we map together with MAMAPA, an integration project for migrants and refugees from Mannheim, CartONG, LECLARA Larabanga and OSM Ghana. We will map HOT-Tasks 8839 and 9928, the former including the city of Wa in northwestern Ghana, the latter in Accra. You can join the event via

Our motivation:

Up to now, not all map data is available everywhere in the world, which often limits the possibilities for disaster prevention and preparedness, needs assessments for relief organisations and many other purposes. So be part of the worldwide OSM mapping community! Everyone is welcome – no matter if you are an experienced mapper or a newcomer! A prepared tutorial provides a suitable introduction for beginners, so that no previous knowledge is required.

What you need:

Prepare a headset to be able to swap and a mouse which will make mapping easier. Unfortunately we can’t provide you with snacks and drinks at the moment – so remember to prepare something; then the event will be even more fun!

Our partners for this mapathon:

The MAMAPA project is conceived both to aid humanitarian cartography and, at the same time, to support the integration of “new arrivers” (migrants, refugees) in the Rhein-Neckar metropolitan region. During the project mapathons, locals and recent arrivers build tandems at each workstation and collaborate on the mapping task. Ample opportunity is provided for contact and conversation in the few hours spent together. (For further information, please visit or mannheimermapathons)

CartONG is a NGO located in Chambéry, France, and provides cartographic and related expertise and services ( e.g. data management, mobile data collection) for humanitarian organizations worldwide. Major clients include Doctors without Borders and the UNHCR. When these organisations are in the field, CartONG works with them to provide maps as well as to generate and manage data essential for mission success. (For further information, please visit;

OSM Ghana, a non-profit organisation, is dedicated to completing the mapping of the country as well as providing training in the use of free and open source geographic tools for humanitarian and developmental goals.The group, active in the FOSS Community, has been involved in the recent past in numerous projects including Open Cities Accra, mapping with LECLARA (Larabanga, Ghana) for sustainable tourism development and participation in the organisation of an African Technical Exchange in Accra for the Secondary Cities project. (For further information, please visit )

LECLARA Larabanga is an organization of local activists in the town of Larabanga, in the Savannah Region of Ghana. They pursue a number of goals important for development in Larabanga, both cultural and educational. Since 2006, (together with the current Project Director of MAMAPA), much was accomplished for primary and secondary schooling (Project “LIEI”), with a particular emphasis on offering educational opportunities for young girls in the village.Located a few kilometers from Mole National Park and home to a Mosque and Koran dating from the 15th/16th centuries, Larabanga has exceptional touristic potential. Since 2016, to spur local development, LECLARA has been involved in building an infrastructure for sustainable tourism. As well, local youth have found opportunities as trained guides.Mapping is essential to this effort. With support from CartONG and OSM Ghana and as the recipient of a HOT Microgrant (2018-19) Larabanga and the surrounding area are now completely mapped. At the same time, workshops on OSM mapping techniques and mobile data collection have been held locally for members of LECLARA. While tourism there (as everywhere else) is currently “on hold”, up-to-date maps are as well an important tool for defending the health and safety of the population both during the current pandemic and into the future. (For further information, please visit or LIEI (pre-2016) .)

We are looking forward to seeing you and are of course always available to answer any questions you may have.

OSM GeoWeek – Mapathon mit dem DRK

Liebe disastermappers Freund*innen,

am Donnerstag,den 19.11. findet um 18.00 Uhr im Rahmen der OSM GeoWeek ein Online-Mapathon statt, der gemeinsam von den disastermappers und dem Deutschen Roten Kreuz organisiert wird. Zugang zur Veranstaltung habt ihr mit diesem Link (Meeting-ID: 825 9708 0617 Kenncode: Maps!@Drk).

Nach spannenden Einblicken in die Internationale Arbeit des DRK und deren Verwendung von freien Geodaten werden wir gemeinsam Gebiete in Togo kartieren. Das DRK benötigt hier Kartendaten für ein Präventionsprogramm um Schäden von Überschwemmungen zu reduzieren.

Bereitet für den Mapathon ein Headset vor, um euch austauschen zu können, sowie eine Maus, welche das Kartieren erleichtern wird. Leider können wir euch zur Zeit nicht mit Snacks und Getränken versorgen – daher denkt daran, euch etwas vorzubereiten; dann macht die Veranstaltung noch mehr Spaß!

Wir freuen uns auf euch und stehen bei Fragen natürlich immer gerne zur Verfügung!

Liebe Grüße,

eure disastermappers
