9.1.3 Phuket
GIS base map has been obtained from GISTDA. Hence, boundary, streams, ponds, water bodies and topography data can be made available. The building footprint of Phuket District
is available at the National Housing Authority database, highlighting the housing and building locations, the emergency infrastructure and facility, the education institutions, and
the medical facilities.
The land use map and the physical coverage of productive sectors like agriculture, tourism, commerce and business sector, industry, is available at NHA and municipality. Landslide risk
mapping has been conducted under RECLAIM II a joint ADPC and Kasetsart university project aiming at mitigating landslide risk in Patong area. Map indicating the Rainfall
patterns and flood risk maps are thus available.
9.1.4 Hat Yai
GIS base map has been obtained from GISTDA. Hence, boundary, streams, ponds, water bodies and topography data are available. The building footprint of Hat Yai District is
available at the National Housing Authority database, highlighting the housing and building locations, the emergency infrastructure and facility, the education institutions, and the
medical facilities.
The land use map and the physical coverage of productive sectors like agriculture, tourism, commerce and business sector, industry, is available at NHA and municipality. Flood risk
mapping is available thanks to TUDMP, a program conducted by ADPC. Data on drainage and sewerage network is available for the Hat Yai District.
9.1.5 Samut Sakhon
GIS base map has been obtained from GISTDA. Hence, boundary, streams, ponds, water bodies and topography data are available. The building footprint of Samut Sakhon District is
available at the National Housing Authority database, highlighting the housing and building locations, the emergency infrastructure and facility, the education institutions, and the
medical facilities.
No proper lLand use map is available for Samut Sakhon area but the land classes mostly agricultural areas can be identified using the maps which are available at NHA. Drainage and
sewerage data are less complete as well as data in relation to power and communication systems.
ADPC has conducted a comparative assessment on GIS and digital data availability among the five pre-selected cities Table 9.2. ADPC assumed the reliability of data is within the
acceptable range for each and every city. As the digital data has been collected for the five cities from the database of the municipality and updated using the data provided by Geo-
Informatics and Space Technology Development Agency GISTDA and field survey the data reliability could be high. The source institutions for supply of digital data are similar for
five cities. ADPC also assume that few gaps exist among the cities concerning the updated
142 status of the digital data used by them although the cities also use the data from the same
sources.
