Web-based data dissemination Census website at URL http://popcensus.nso.go.th as a mean of census information and data dissemination via internet in which various products of Census results are put on web for viewing ,downloading or printing out such as report , quick tables , quick statistics /indicators
D ata warehouse for interactive tabulating data. NSO-GIS system for interactive thematic maps display . Census Info put on web and CD-ROM
Micro data ( only 1 % will be released )
Customized data requests as well
GIS for census data disseminationGIS for census data dissemination
There are 2 map services on line :
1.NSO-GIS is Statistical Geographic Information
System which use GIS and web map /web feature
service of OGC standard technology for census and
survey data dissemination by thematic map. The
Interactive Thematic maps can be selected to display at
region level down to sub district level.

2. Census Info adapted from DevInfo
technology as well as TPD Info which
address adhoc issues ,ie., MDG , poverty
(Table , Graph and Map ).
NSO-GIS (Statistical Geographic Information System )
NSO-GIS was developed in 2009 by outsourcing
Selected 17 census/survey projects with 197 core
indicators were designed for producing web based
thematic maps
NSO-GIS web map service was launched on 1 July 2009
Census and survey data base as well as thematic maps are
updated regularly

2. Thematic map report
2010 Census Map in NSO-GIS
Most indicators are the same as 2000 Census
Population : No. of population, Non Thai
population , Density of population , % of pop. in
municipal area, growth rate
Demographic and social characteristics :
% of pop. by age group, nationality, religion,
marital status, education , occupation ,sex ratio,
literacy rate , migration rate, fertility ,etc.
2010 Census Map in NSO-GIS (cont.)
Housing : % of hh. by type of residence
material used , availability of clean drinking water
and sanitary toilet, type of fuel used , type of ICT
used, possession of durable goods

Constraint of developing NSO-GIS
1. The personnel in charged of GIS for data
presentation are statistician so they lack of
skill in Thematic mapping and GIS web
based administration .
2. Lack of knowledge on GIS,ICT technology ,
spatial analysis techniques as well as
experience in applying GIS with statistical
work.
