Abstract
The United Nations (UN) has performed field operations worldwide such as peacekeeping or rescue missions. When such an operation is needed, the UN dispatches an operation team usually with a GIS (Geographic Information System) customized to a specific operation. The base maps for the GIS are generated mostly with satellite images which may not retain a high resolution and the current situation. To build an up-to-date high resolution map, we propose a UAV (unmanned aerial vehicle) based automatic mapping system, which can operate in a fully automatic way from the data acquisition of sensory data to the data processing for the generation of the geospatial products such as a mosaicked orthoimage of a target area. In this study, we analyse the requirements for UN field operations, suggest a UAV mapping system with an operation scenario, and investigate the applicability of the system. With the proposed system, we can construct a tailored GIS with up-to-date and high resolution base maps for a specific operation efficiently.

The GIS provides the functions of analysis, interpretation and visualization based on geospatial information, and help us understand spatial trends of events or plan for responses for the events efficiently (ESRI, 2011)

Summary
One of the main missions of UN (United Nations) is peacekeeping to maintain international peace and security. The UN peacekeeping helps parties in disputed or troubled regions make a peace agreement and monitors whether they maintain the agreement It provides SAR (Search and Rescue) and restoring operations in disaster areas as well. The UNGSC (UN Global Service Centre) within the DFS (Department of Field Support) provides the mission specific and adaptive GIS with the DPKO. Those GIS are established in accordance with the GIS Service Catalogue and Performance Management framework (UNGSC, 2010). The mission area is hardly accessible because of political/military conflict, disaster damage and so on In those cases, mapping systems based on a UAV is very expeditious means to acquire high resolution data on the mission area (Choi et al, 2011).
