ANALYSIS SUMMARY: A total of approximately 2,480 tents and building structures were identified with a high degree of confidence within the well-defined and structured transitional camp site encompassing a current area of approximately 40ha. Of this total, 2,220 tents were likely erected for displaced people as on 21 March 2011, with a further 260 tents and fixed buildings likely allocated for camp infrastructure and staff. Between 3 and 21 March 2011, the camp expanded significantly in both size and capacity, adding over 1,200 tent shelters as well as a range of purpose-built structures likely dedicated for food, health, sanitation and camp management. Tent shelters erected in early March were also extensively reorganized in several areas in order to improve shelter density, distribution and internal foot traffic. Based on an analysis of the average tent shelter size, the camp had as of 21 March a capacity for a little over 12,000 people according to official UNHCR recommended standards. There was also ground prepared which could accommodate approximately 500-600 additional tents. Coordinate System: UTM Zone 32N; Datum: WGS 1984.
