Dear all,

 

Two new UNOSAT satellite image assessments are now available. These are 
also included in the latest KML file (see below).

 

*Overview of IDP Concentrations in Port-au-Prince and Carrefour, Haiti 
(Update2)*

This map presents an overview of temporary shelter locations of 
displaced Haitians in Port-au-Prince and Carrefour, as identified in 
satellite imagery recorded on 13 January 2010. These IDP locations range 
in size from small clusters of survivors (approx 20-50) to large 
concentrations numbering in the low thousands. Locations are commonly 
situated in open areas away from unstable buildings, in parks, sport 
fields, church compounds and grassy medians of main roads. Four case 
examples are show in the imagery.**

*Density of Bridge & Road Obstacles in Port-au-Prince and Carrefour, 
Haiti (Update2)*

This map illustrates the relative spatial density of major road and 
bridge obstructions in Port-au-Prince and Carrefour, as identified in 
satellite imagery recorded on 13 January 2010. A total of 691 obstacles 
were identified, almost all due to collapsed buildings and related 
debris, in only a few cases were the obstructions the result of 
landslides. Of this total, 224 were likely completely blocked to 
motorized traffic and 467 were partial obstructions restricting vehicle 
access. Four case examples of specific road obstructions are shown in 
the imagery.**

 

Note: This is a preliminary analysis; road and bridge damages may be 
underestimated. Please send corrections to UNITAR / UNOSAT:  
unosat at unitar.org <mailto:unosat at unitar.org>.
