3. The Main Tasks of Statistical Mapping Subdirectorate
Managing regional statistical offices in sketching maps of enumeration areas and administrative areas (province, regency/city, subdistrict, and village)
Managing regional statistical offices in coding administrative area and enumeration area
Archiving enumeration area and administrative area sketch maps
Digitizing and updating administrative boundaries based on administrative area sketch maps
Making census maps for publication

4. Availability of Maps in BPS
Sketch maps  guidance for enumerator
Province by regency/city
Regency/city by subdistrict
Subdistrict by village
Village by enumeration area
Enumeration area
Digital maps  making census map
Indonesia by province, regency/city, subdistrict, and village

B/K/P
Type of enumeration area:
B = Biasa  ordinary
K = Khusus  specific
P = Persiapan  empty
Series number:
001,002,003,...

8. Administrative Area Index Map

9. Index Map of Jawa Barat Province by Regency/City

10. Index Map of Purwakarta Regency by Subdistrict

11. Index Map of Purwakarta Subdistrict by Village

12. Sketch Map of Province by Regency/City

13. Sketch Map of Regency/City by Subdistrict

14. Sketch Map of Subdistrict by Village

15. Sketch Map of Village by Enumeration Area

16. Sketch Map of Enumeration Area

17. Developing Digital Map
Started in 1994; collaborated with National Coordinating Agency for Survey and Mapping to obtain digital map of Indonesia by regency/city (scale 1 : 250,000)
Digitizing subdistrict boundaries inside each regency/city polygon based on sketch map of regency/city by subdistrict
Digitizing village boundaries inside each subdistrict polygon based on sketch map of subdistrict by village

18. Use of GIS Software
Digitizing administrative area boundaries based on sketch maps  ArcInfo
Administrative area index mapping  ArcView
Statistical mapping  ArcView; ArcMap
Statistical GIS  MapObject

19. Average of Agricultural-Household Income

20. IMR of East Java Province by Subdistrict

21. GIS for Nutrition Mapping

22. GIS for Poverty Mapping 1

23. Recent Program and Planning
Upgrading accuracy of administrative area digital map
Using GPS
On screen digitizing administrative area boundaries based on topographic map of National Coordinating Agency for Survey and Mapping or such as Google Earth’s map
Delineating enumeration area boundary using GPS
Developing statistical WebGIS

24. Reason for Upgrading Accuracy of Administrative Area Digital Map (1)
Digitizing administrative boundaries based on administrative area sketch map caused the digital map is not geo-referenced. This map actually can not be used for spatial analysis purpose.
National Mapping Office can not provide yet administrative area digital map for village level; many people and institutions using BPS’ digital map, even for spatial analysis purpose.

25. Reason for Upgrading Accuracy of Administrative Area Digital Map (2)
Geo-referenced digital map can improve accuracy of statistics related to area and distance.
Geo-referenced digital map can be used for spatial and geo-statistic analysis purpose.

26. Planning for Preparation of 2010 Population Census (1)
Reforming enumeration area
Current enumeration area is not familiar to local people, so the enumeration area will be reformed based on neighborhood association
Sketching maps of enumeration areas and administrative areas
Reforming enumeration areas and sketching maps of enumeration and administrative areas will be conducted in 2008 and The priority regencies will be subdistricts/villages area which are predicted unchanged until Population Census 2010

27. Planning for Preparation of 2010 Population Census (2)
Delineating boundaries of enumeration and administrative areas using GPS are started in The priority will be the big cities.
BPS needs assistances of institutions (UNSD or other) for making enumeration area maps for 2010 Population Census

28. Study for Delineating Boundaries Using GPS (1)
Conducted in 2006 and 2007
Finding:
Sometimes boundaries of enumeration/ administrative area can not be traced
Week or no signal in dense populated area
When the administrative area boundaries can not be delineated with GPS, the boundaries can be delineated with on screen digitizing topographic map or high-resolution such as Google Earth’s map, but the maps are costly enough

29. Study for Delineating Boundaries Using GPS (2)
GPS data processing is not so easy, training is necessary
Indonesia is very wide country, there is 33 provinces, 456 regencies and cities, 5905 subdistricts, and villages. Ideally 1 GPS receiver is used to delineate 10 villages  BPS needs about 7230 units of GPS receivers  inadequate financial allocation
