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

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

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

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.
