Elke dag zijn hulpverleners van het Rode Kruis en andere organisaties actief in gebieden waar hulp nodig is. Soms omdat er net een ramp geweest is, soms om te zorgen dat het gebied is voorbereid op een ramp.

In beide gevallen zijn goede kaarten belangrijk om efficiënt te helpen. Ze laten hulpverleners bijvoorbeeld zien waar veel mensen wonen en hoe de wegen in een gebied lopen.

Helaas zijn deze kaarten er lang niet altijd. Vaak zijn ze hopeloos gedateerd of bestaan ze domweg niet.

Maar er is goed nieuws: iedereen kan helpen om in korte tijd gigantische gebieden in kaart te brengen. Ook jij. Alles wat je nodig hebt is een laptop of computer met internetverbinding.

Wil jij hulpverleners en bewoners van rampgebieden helpen aan betere kaarten? Mappen kost je geen geld, is makkelijk te leren en leuk om te doen. We helpen je graag verder op onze instructiepagina

Every single day the Red Cross, United Nations and other NGO volunteers and employees are active in areas where help is needed. Whether it be in response to a disaster or preparing in case of a disaster, good maps are a necessity to organize the help efficiently. However, these maps are often outdated or not existing.

The good news is with modern technology and methods, trained volunteers can now contribute to the creation of maps within short time frames. In order to create maps faster 510 Global works with & uses the tools from various skilled partners to create those needed maps. HOTOSM, MISSING MAPS & POSM to name a few. Scroll down to learn more about our partners and the links to their Learning materials.


The Humanitarian OpenStreetMap Team (HOT aka HOTOSM) applies the principles of open source and open data sharing for humanitarian response and economic development. HOT develops several open source programs and applications to leverage collaborative mapping and the use of new technologies in the field of geographic information for humanitarian aid.

In terms of the projects 510 works on HOT sets the areas needed to be mapped in Disaster Response (DR) in their tasking manager. The HOT tasking manager allows you to select the tasks for mapping at Missing Maps Mapathons or at home!


Each year, disasters around the world kill nearly 100,000 and affect or displace 200 million people. Many of the places where these disasters occur are literally ‘missing’ from any map and first responders lack the information to make valuable decisions regarding relief efforts. Missing Maps is an open, collaborative project in which you can help to map areas where humanitarian organisations are trying to meet the needs of vulnerable people.
 The team at 510 coordinates mapathons in The Netherlands where volunteers come to map for good!  We use HOTOSM tasking manager to select and prepare the areas to be mapped, giving an introduction, helping the people with mapping, organising the validation and supporting people who live in the mapped area to improve and sustain their regional maps.

Developed by The American Red Cross and used by many other agencies. POSM was developed to use in an extremely remote area without dependable internet or cellular connectivity, where volunteers have to be offline and inaccessible for days or weeks at a time. POSM (Portable OpenStreetMap) – lets us conduct major field efforts and work entirely offline for months at time.

POSM is a hardware device loaded with offline versions of software. POSM broadcasts a wireless signal that other devices can connect to in order to access tools that ordinarily require an internet connection.

Currently, POSM includes support for GIS and mapping tools used by the Missing Maps project:
