It is about to define the administrative boundary changes, and compare the present region to the footprint of administrative territory changes over the historical timeline. we use the semantic web and linked open data concepts to represent the phenomena

boundary revisions
 To create a spatial database of different hierarchy of
administrative boundaries with temporal reference

8. What extent city can be expanded?
Time period of event reapeat?
End point of two time can be explaine as:
Before(<), meets(m), overlap(o),start(s), During(d), Ends(e), after(>),
meetsBy(m~), overlapBy(o~), startBy(s~),includes(i), endededBy(e~)
Expansion can be explained as: join, reunited, partof , adjacent
Re devision: speration, seperatedfrom, changed name , dividedInto
Boundary can be expressed as polygon geometry of set of points
What about the linear facilities?

10. Possible Data Source:
 LGED
 BBS
 DCC—Historical boundary information
Software and procedure:
 ArcGIS10.0, ArcGIS oneline
 PostGIS for Spatial Querry
Web application development in web as
well as smart phone platform

11. A linked opendata Resources
A rcih database
BoundaryExtentionUnionRedivision
A web application:
Customised search facilities with smallest subdivision at community
level, even with ZIP code with appropriate higherarchy information
Dhaka City
Old Dhaka (Origin)
New
Dhaka(Extention)
South Dhaka
North Dhaka
This linked data will link all other basic information about the change and
current state

12. Base data for researcher, decision maker
New base data to update further change
Base line information to help service
redistribution
Querry facilities
Add new resource to linked open data
cloud
