DRMInfo is a tool for organizing, analyzing and presenting geographical, socio-economic and other useful scientific information to support Disaster Risk Management decisions. It is an adaptation of the UNICEF DevInfo 6.0 software for specific use in Timor-Leste, and contains local maps and information. National Disaster Management Directorate staff and members of District Disaster Management Committees are the principal operators of DRMInfo. These staff should have a basic capacity to operate Windows software. They will use DRMInfo to prepare information products; primarily thematic maps, but also tables and graphs, which show the nature of the disaster risk environment at the national, district and lower administrative levels. In the course of their risk assessment activities, members of Disaster Management Committees may go to the National Disaster Operations Centre or District DOCs to request specific information products to be made for them using the DRMInfo resources available at those sites. The use of DRMInfo, as well as the data contained within it, is structured according to the following principle: “Sources of risk”, such as floods, drought, high winds and pests; and “elements at risk”; such as houses, infrastructure and crops; interact to produce disaster risk situations with a range of likelihoods and severities. Accordingly, DRMInfo organizes its information into those two categories. This user manual is focused on how DRMInfo can be used for producing disaster risk maps for analysis, according to the interest of the user. After working through this manual, the reader who has DRMInfo software on their computer should be able to produce maps of any suco, sub-district or district in Timor-Leste that provide a description of the risk environment.
