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

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

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

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 Earths 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 2009. 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
  2009. 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 Earths
  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 72303 villages. Ideally 1 GPS
  receiver is used to delineate 10 villages ? BPS
  needs about 7230 units of GPS receivers ?
  inadequate financial allocation
