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If location data is out of date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  • Quickly out of date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

Overview

  1. Map interface – select the unit or units to change
  2. Click on the button for the change
  3. Provide details of changes

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.
Spatial data 12.png


  • 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

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