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:
