==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If location data is out of date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* Quickly out of date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 ====
# Map interface – select the unit or units to change
# Click on the button for the change
# Provide details of changes
# Save changes

==== Map Interface ====

==== Map interface - navigation ====
'''Pan'''
* Click and drag

'''Zoom in'''
* Double click, or
* Zoom slider, or
* Zoom button

''' Zoom out'''
*Zoom slider, or
*Zoom button

==== Selecting single units ====
* Float over province to see the name
**It will be shown in blue
[[Image:Spatial_data_4.png|500px|centre]]

* Single click on a province to select
**It will be highlighted in yellow
**The kabupaten will be shown in green
[[Image:Spatial_data_5.png|500px|centre]]

* Zoom in to see districts better
* Float to see the name
** Blue highlight

* Single click to select
* Yellow highlight
* Kecamatan boundaries will be shown

==== Selecting multiple units ====
# Hold down shift key
# Click on the first unit
# Keep holding down the shift key
# Click on the second unit
# Repeat until all units are selected
# Release the shift key
# Selected units are outlined in black

==== Operations ====
'''Edit'''
* Change the name of a unit

'''Split'''
* Split one desa into two desa

'''Move'''
* Move a unit from one parent unit to another

'''Merge'''
* Merge two desa into a single desa

'''Create'''
* Create a new unit from several other sub-units

===== Edit =====
* This is used to change the name of a
** Desa
** Kecamatan
** Kabupaten
** Provinsi

1. Select the unit on the map interface
[[Image:Spatial_data_9.png|500px|centre]]
2. Click on the Edit button
[[Image:Spatial_data_10.png|500px|centre]]
3. Edit the name
[[Image:Spatial_data_11.png|500px|centre]]

===== 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.

[[Image:Spatial_data_12.png|500px|centre]]

* 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

[[Image:Spatial_data_13.png|500px|centre]]

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)

[[Image:Spatial_data_14.png|500px|centre]]

* 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
[[Image:Spatial_data_15.png|500px|centre]]

* 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 =====
Creates a new higher-level unit from a collection of units
For example
* 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
