Import Ghana Health Facilities
Goal
The goal is to import ~3000 health facilities collected by Ministry of Health under government of Ghana for the 10 administractive regions of Ghana.
Schedule
- Data clean up
- Import should start as soon as OSM community comes to an agreement.
Import Data
Data description
The datasets are drawn and generated by the Ministtry of Health, Ghana.
The original dataset consists of 1,096 health facilities entries, in .csv format and uploade to the Ghana Open Data portal. – data.gov.gh
The dataset contains 8 fields:
- Region
- District
- FacilityNa
- Type
- Town
- Ownership
- Latitude
- Longitude
Background
ODbL Compliance verified: YES
Import Type
The import will be done manually through one job in the HOT Tasking Manager (TM), having for each task of the job only the health facilities nodes that lie within the task tile, in a similar way as it was done for the Central African Republic UNICEF import. For each task, we will first check the MoH nodes to be imported, and second we will assess the data already in the OSM database against the MoH one for the merging of the MoH data into the OSM database. The OSM mappers who will contribute to this import job will follow a detailed workflow to accomplish this.
Data Preparation
Data Reduction & Simplification The data is originally in csv format, in only one file for the whole of Ghana. It was clipped against Ghana country boundary to remove features out of bound which might have been a result from data entry.
Tagging Plans
Each health facility will have the following tags:
| MoH Key | OSM tag | Observations |
|---|---|---|
| Type | amenity=hospital / amenity=clinic / healthcare=birthing_centre / office=government / =* | |
| All objects | source=MoH, Ghana - data.gov.gh | |
| Region | addr:state=* | |
| District | addr:district=* | Local goverment |
| Town | addr:place=* | |
| Ownership | ownership=* | Private / Government |
| FacilityNa | name=* | CHPS = Community-Based Health Planning and Services, RCH = Reproductive Child Health |
Changeset Tags
We will use the following changeset tags:
- comment=Ghana Health facilities import, #hotosm-task-#
- created_by=JOSM/version
- source=date.gov.gh
- source:date=2013
- import=yes
- url=https://wiki.openstreetmap.org/wiki/Import_Ghana_Health_Facilities
Data Transformation
Data is in csv format. It was processed in QGIS to shapefile and converted to .osm format in JOSM.
Data Merge Workflow
Team Approach
Import will be undertaken by experienced OSM mappers, using a import specific OSM user account, following a workflow and working through a HOT Task Manager job similar to the ones set for the import of UNICEF health facilities, schools and water resources in Central African Republic.
References
The import will be discussed in the import list and in the Talk-gh list.
Workflow
You can see the workflow here.
Reverse plan
In case of any trouble, JOSM reverter will be used.
Conflation
The location of the MoH nodes is generally correct or approximate, but following the already mentioned workflow, we will place the nodes in the exact position. For example, for a hospital compound, we will place the node more or less at the centre of it, in case it is not centered.
If other health facilities are encountered, they will be compared with the import ones and merge the data in the best possible way, keeping all info that the old ones may have. In case of doubt, a fixme tag will be placed, the issue will be reported through the comment of the task (tile) of the TM job, and the user that uploaded the old health facility node would be eventually contacted if needed.
