Spatial data management manual

Changing administrative boundaries : A guide for iSIKHNAS Coordinators

Background

Spatial data

Spatial data includes data about locations, names and boundaries of

• Desa
• Kecamatan
• Kabupaten
• Provinsi

Boundaries change

For example

• 1 desa split into two desa
• Kecamatan moved from one kabupaten to another
• Name of Kecamatan changed
• New province created out of kabupaten from another province

Importance of spatial data

In iSIKHNAS, all data is linked to a location. This allows

• Analysis
• Mapping
• Identifying area of responsibility

If location data is out of date

• Users cannot submit accurate data

The problem

Official national data from BPS

• Only updated annually
• Quickly out of date

The solution

The people that know about the changes first are the local staff

• iSIKHNAS coordinators

iSIKHNAS will offer a way for kabupaten and provincial coordinators to update any changes to the spatial data directly on the web

Advantages

• Coordinators can fix any problems immediately
• Data is always accurate, using local knowledge
• iSIKHNAS tracks changes in the names and boundaries over time
  • Historical data is mapped with old maps
  • New data is mapped with new maps

Split

This is used when one desa is split to become two desa (a new and an old).

You need to mark the line of the new boundary between the two desa.

• Select a single desa
  • Only desa can be split, not higher level units
• Zoom in so the desa fills most of the screen
  • This will make it easier to edit

You now need to mark the line that divides the desa into two new desa.

• If available, copy this line from a map.
• The line may follow a river or a road – trace it on the map
• If you don’t know, you can draw a line in the middle of the desa where you estimate the boundary should be
• Try to be as accurate as possible, but don’t worry if the line not exactly right

• Click on the Split button
• With the mouse, single-click on a series of points that mark the new boundary to split the desa
  • Start with the first point outside the desa
  • Then single-click points close together along the line until you get to the other side of the desa
  • Double-click the last point outside the desa to finish

• The system will ask you which is the new desa
  • Click to select the new desa
  • Edit the name and save

Move

• Move is used to move a unit from one parent unit to another

For example

• • Move a desa to a different kecamatan
  • Move a kecamatan to a different kabupaten
  • Move a kabupaten to a different province

• The moved unit will get a new location code
  • So will all sub-units (eg desa in a kecamatan)

• Select one or more units to be moved
  • They must all be at the same level
    • All kecamatan, or all desa
  • They must all be in the same parent unit
    • Kecamatan in the same kabupaten
    • Desa in the same kecamatan
• Click on the Move button

Click on the unit to move to

• This must be a parent unit
  • If you are moving desa, you must choose a kecamatan
  • If you are moving kecamatan you must choose a kabupaten
• It must be next to the selected units
  • It must have a common boundary

• Click OK
• The units will be given a new location code
• The boundaries of the parent and higher units will be recalculated

Merge

• Two desa are joined into a single desa

• Select the two desa to merge
  • Only desa can be merged (not higher units)
  • The desa must be next to each other (share a common border)
• Click on the Merge button
• Select the old desa with the name that will be kept for the new desa
• Click OK

Create

• A new province from one or more selected kabupaten
• A new kabupaten from one or more selected kecamatan

• Select one or more units
• They must all be at the same level
• They must all be next to each other
• Click Create
• Enter the name for the new parent unit
