Data for: Assessment of post-tsunami disaster land use/land cover change and potential impact of future sea-level rise to low-lying coastal areas: A case study of Banda Aceh coast of Indonesia
The data provided here include the delineation of Land Use / Land Cover (LULC) of Banda Aceh coastal system. The LULC type polygon maps produced by a delineation of discernible objects on the individual satellite image of 2004, 2011 and 2017, and stored them in polygon shape format. The delineation was performed by using the unsupervised LULC classification scheme, digitized from each of the individual high-resolution satellite images of 30 x 30 cm pixels. We identified and validated objects and patches specific to different types of LULC from each satellite image based on our familiarity with the study area. Three sets of high-resolution satellite images acquired on 23rd June 2004 (pre-tsunami December 2004), 1st March 2011 and 14th May 2017 retrieved from the Google Earth Pro - Digital Globe, were utilized for LULC delineation using ArcGIS software. Each of the acquired satellite images was already geo-referenced and spatially rectified. Eight types of LULC, including the aquaculture, bare land, building area, lagoon, mangrove, rice field, river and sea, were delineated for the individual satellite images. The quantifiable land use and land cover were delineated as polygons of aquaculture, bare land, building area, lagoon, mangrove and rice field. Figure 4 displays the polygon maps of the LULCs delineated from the high-resolution satellite images.
