aftermath of the Haiti earthquake. Swisstopo provided extensive pre-crisis building data in direct technical support of this UN damage analysis. Initial reference data were received from coThis map presents a total building count and damages as assessed from both satellite and aerial survey imagery covering the Commune of Port-au-Prince. Damaged buildings were classified according to visually-assessed damage levels and summarized in a table by Commune Sector. This work is done at the request of UNDP, and in support of the UN-led efforts in the aftermath of the Haiti earthquake. Swisstopo and the Remote Sensing Laboratories (RSL) at the University of Zurich provided extensive pre-crisis building data in direct technical support of this UN damage analysis. Initial reference data were received from collaborative centers (European Commission JRC with the support of the Stability Instrument; Sertit/Space Charter) and other supporting entities (ITHACA, DLR, OSM). This analysis will be validated in the field during PDNA and recovery activities.

This work was done in support of the international humanitarian relief effort in Haiti following the earthquake on 12 January 2010, bridges and road obstacles have been identified in GeoEye-1 imagery recorded on 13 January 2010. Road data and corresponding attributes shown in the map are updated as of 20 January.This is a preliminary analysis & has not yet been validated in the field. Road and bridge damages have likely been underestimated. Please send ground feedback to UNITAR/UNOSAT.

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. This is a preliminary analysis & has not yet been validated in the field. Please send ground feedback to UNITAR / UNOSAT.

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. This is a preliminary analysis & has not yet been validated in the field. Please send ground feedback to UNITAR / UNOSAT. Map scale for A3: 1:55,000; projection: UTM zone 18N, WGS84.

A preselected list of major buildings and urban facilities were assessed for damages using GeoEye-1 satellite imagery recorded on 13 January 2010. Building sites have been identified by local name and classified by type when possible, with a focus on hospitals, government and UN offices, schools, churches and industrial complexes. Damage classes have been assigned based on visual interpretation of available satellite imagery and thus contain an associated level of uncertainty for buildings with less severe forms of damages. Sites marked as \"No Visual Damage\" may have major structural damages not identifiable in the imagery, thus damages in the analysis have likely been underestimated. Note also that the major sites evaluated are not exhaustive of all important buildings within the city. A total of 110 selected sites were assessed; of this total 58 sites (53% were visibly damaged or destroyed. The percentage of affected buildings by type: Educational = 50%; Government = 88%; Hospitals = 42%; Int. Org. Offices = 50%; Churches = 60%. This is a preliminary analysis & has not yet been validated in the field. Please send ground feedback to UNITAR / UNOSAT.
