The Project

• Roughly 35,000 people of Northern, Haiti living
  and working in the vicinity of Les Moustiques
  river, are seasonally inundated by flood waters.
  
• Engineers from Herrera Consultants Inc. are
  planning a site visit to the area to assess the
  situation and create design alternatives.
• Before they go, they need a set of field maps of
  the basin area.

Objectives

• It was our task to create GIS maps of the
  basin and watershed surrounding Les Moustiques in
  Haiti. In order to complete this task we needed
  to delineate the Riviere Moustiques drainage
  basin (watersheds, sub-basins, and streams), and
  develop georeferenced GIS maps of la plain de
  Moustiques.

How We Built the Maps

• First, we converted the point data of the
  contours into a surface using the spatial analyst
  interpolate to raster tool

How We Built the Maps

• Secondly, we used the spatial analyst
  hydrology tool and the raster calculator to
  create the watershed, basins, and streams.

• Thirdly, we georeferenced our aerial photo to
  our contoured data.
