Using Geospatial Techniques to Compare Real Estate Potential of Three residential Manmade Islands; Amwaj Islands, Reef Island and Durrat Al Bahrain in the Kingdom of Bahrain


Authors: Ali El battay
Abstract: Amwaj Islands, Reef Island and Durrat Al Bahrain are leading artificial islands residential projects in the kingdom of Bahrain. This study focused on the use of geospatial techniques to produce a comprehensive comparison between all these three developments (at the level of the whole project not individual buildings). A Landsat 8 OLI image was used alongside of high resolution optical images (DigitalGlobe products) to extract main features in the three study areas. Temporal percentages of overall completion; 58% for Amwaj, 51% for Reef Island and 20% for Durrat Al Bahrain was determined via classification. In addition, using a high pass filter the road feature was digitized and a density of 9.31 Km of roads per Sq. Km of the project was determined in Amwaj Islands, vs. 5.31 in Reef Islands and only 2.52 in Durrat. Beach ratio (water front percentage) was respectively 8.2 km of waterfront per Sq. Km of the project for both Amwaj and Reef, and 5.9 for Durrat. Thermal band (TIR) from the same Landsat-8 was used to compare water surface temperature in all three projects, where Durrat Al Bahrain has the deepest water and the coolest temperature. The second part of this study used calculated the Average travelling time and distance between these three Islands projects and the main destinations in the Kingdom of Bahrain. Results show that Amwaj and Reef Islands have a TTMD of 230 mn and 186 mn Respectively, while Durrat Al Bahrain had a TTMD of 325 mn. Even though, this study has focused on the islands as a whole, which gives the contextual environment to perform a determination of the real value of their properties.

KEYWORDS: beach ratio, Landsat 8, sea surface temperature, road density, travel time/distance to main destinations
