9 Data availability for further study
9.1 Availability of spatial data
ADPC first concern lies on the acquisition of relevant data for the study for each of the five cities. This type of data is essential for monitoring urbanization trends, locations of urban
settlements and density, disaster related impacts, and climate trends etc. and are highly useful for forming an analytical view and comparative assessment. GIS base maps are available for
each and every city but are used for different purposes such as Taxation. Building footprint maps for the five cities are available at The National Housing Authority NHA. The
topographic map of Thailand is available; thus the topography of one specific city can be analyzed.
The limited understanding between Thai institutions concerning the GIS data availability and standards is one of the challenges faced by the team during the data collection process. In fact,
each institution opts for a particular projection system observed to be resulting in a substantial spatial shifting from one map to another.
9.1.1 Chiang Rai
GIS base map has been derived from the Municipality Taxation map and updated using data obtained from GISTDA. Hence, boundary, streams, ponds, water bodies and topography data
could be made available. The building footprint of Chiang Rai District is available at the National Housing Authority database, highlighting the locations of housing and building, the
emergency infrastructure and utility facilities, 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, are available at NHA. Drainage and sewerage data
are less complete as well as data in relation to power and communication systems.
9.1.2 Udon Thani
GIS base map has been derived from the Municipality Taxation map and updated using data obtained from GISTDA. Hence, boundary, streams, ponds, water bodies and topography data
could be made available. The building footprint of Udon Thani District is accessible through the Taxation Department of Municipality, highlighting the housing and building locations,
the emergency infrastructure and facility, the education institutions, the medical facilities.
The land use map and the physical coverage of productive sectors, like agriculture, tourism, commerce and business sector, industry, are available and have been provided by
municipalities. Drainage and sewerage data are available as well as data in relation to power and communication systems.

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
