Buildings mapping in Macaya Park

Anthropogenic activities in the park have been identified as problematic by local authorities, particularly for the recovery of vegetation in their surroundings. It was asked to see to what extent spatial images can allow the identification of human activities in the park.

This inventory is carried out on two separate dates, in order to obtain a database characterizing the evolution of the occupation of the Park according to two temporal milestones: a pre-Matthew state, and a post-Matthew state (in this case a year after).

Conclusion (Summary)

This study made it possible to carry out the mapping of the building on the set of two protected areas of the Macaya Park, increased by a buffer zone of 500 meters, for 2014 and 2017. However, this analysis is exhaustive for the first date, but n is only partial for the second, due to the presence of clouds.

Exploitation of the geographic database revealed habitat loss on two large settlements in the northeast and northwest. The most densely populated area of the Park, located on the southern part, also suffered a significant loss of habitat, but was offset by the construction of new buildings. It is very likely that this dynamic is related to the damage caused by hurricane Matthew, and the post-crisis reconstruction.
