CartONG is a Non-Governmental Organization (NGO) specialized in mapping and data management whose mission is to put data at the service of humanitarian, development and social action projects. As a Humanitarian to Humanitarian (H2H) organization, we aim to tackle the technical, strategic and ethical challenges of digital technologies in support of the aid community. As a multidisciplinary resource and expertise center, our team of staff and volunteers supports the organizational strategy and the field operations of a wide array of actors including NGOs, international organizations and institutional actors. CartONG also closely works with other H2H nonprofits as well grassroots organizations and local communities. Our use of data management tools and methodologies is dedicated to better understanding the challenges faced in field environments and to improving the quality and accountability of field activities, in particular through improved needs assessments and monitoring and evaluation. CartONG was founded in 2006 by cartographers in Chambéry, France. Our areas of expertise embrace the entire spectrum of data management, including GIS, mobile data collection, data processing and transversal IM approaches.
