In planning the city&#8217;s reconstruction following the earthquake, the Ministry of Rural and Urban Planning, together with an internal aid agency, is funding a project to map the extent of building damage.\u00a0 There was virtually no reliable digital geospatial data documenting the city&#8217;s urban form before the earthquake, although following the disaster, building damage has been mapped on the ground by recovery teams equipped with differential Global Positioning System (GPS) units in some areas.\u00a0 However, access on the ground remains difficult in many areas, making a complete ground-based survey impossible.\u00a0 Both government and the international agency wish to use remotely sensed data to resolve this problem.<\/p>\n<p>In a report (maximum 1,800 words), drawing on relevant literature, assess the strengths and limitations of data from different remote sensing systems for use in this scenario. <span>\u00a0Based on this assessment, provide a recommendation on the source\/s of remotely sensed imagery you would consider using for this exercise.
