Data

Data description

The original dataset consists of 17,657 education facilities nodes, in geojson format.

Current number of schools in OSM in Mozambique - 904

  • College - 48
  • Kindergarten - 49
  • Primary & Secondary - 727
  • University - 80

Background

Data source site: https://maps.giga.global/map

Type of license: CC-BY-SA 4.0

OSM attribution: GIGA

ODbL Compliance verified: yes

Permission status: A permission letter has been secured and is documented here.

Import Type

The import will be done manually through JOSM, the data will be split by district, and the import for each district will be handlled by different mapper. For each district, we will first check the education facilities nodes to be imported, and second we will assess the data already in the OSM database against the Mozambique Schools data, for the merging into the OSM database. The OSM mappers who will contribute to this import project will follow a detailed workflow to accomplish this.

Note: Each facility node is a very good source of place=* data. Many of the places where these facilities are located aren't yet in OSM, so we can use that information to produce place nodes. But that info will better be incorporated in a different and independent import project.

Data Preparation

Data Reduction & Simplification

The data is originally in csv format. You can download the original data from here.

Tagging Plans

Each education facility node will have the following tags:

Giga Schools key OSM tag Comments Link
Source source=Giga Source of the information Key:source
SchoolID ref:mined Official government school ID
Escola name Official name of the school https://wiki.openstreetmap.org/wiki/Key:name
latitude latitude Not uploaded to OSM
longitude longitude Not uploaded to OSM
EP / ES1 / ES2 isced:level= 0, 1, 2, 3, 4, 5, 6, 7, 8 Education level of the school https://wiki.openstreetmap.org/wiki/Key:isced:level
Distrito addr:district District name https://wiki.openstreetmap.org/wiki/Key:addr:district
Provincia addr:province Province name https://wiki.openstreetmap.org/wiki/Key:addr:province
TemElectricidade yes/no yes/no https://wiki.openstreetmap.org/wiki/Key:electricity
TemInternet internet_access yes/no
amenity amenity=school, kindergarten, university, college New tag added https://wiki.openstreetmap.org/wiki/Tag:amenity%3Dschool

Changeset Tags

We will use the following changeset tags:

  • #MozambiqueSchoolImport

To the comment=* tag, you may need to add particular comments to the changeset.

Data Transformation

Data will be in geojsom format. It will be opened in JOSM with the OpenData plugin, and then processed the osm file and convert it to a new osm file with a script. The script will put in lowercase the texts that are all uppercase (except first letter of each word), and add tags according to the tagging schema. It will also convert strings like for example 'Esc.' to 'Escola' or 'EPC' to 'Escola Primária Completa.

Data Merge Workflow

Team Approach

Import will be undertaken by experienced OSM mappers, using an import specific OSM user account, following a workflow using JOSM and the Todolist Plugin.

References

The import will be discussed first in the OSM Mozambique community channels, and then in the OSM Community Forum.

Workflow

You can see the workflow here.

Reverse plan

In case of any trouble, JOSM reverter will be used.

Conflation

The location of the education facilities nodes is generally never more than 150-200 m of the real location, but following the already mentioned workflow, we will place the nodes in the exact position. In case we can't be sure about the location (quite rare), we will leave them in the original position and add a fixme=Please, check the position of the node tag to the node. For school points that exist in un inhabitted areas, and very far away from any settlements, these will not be imported.

If other education facilities are encountered, they will be compared with the Mozambique Schools dataset as well as the Giga schools dataset and merged, keeping all info that the old nodes have. In case of doubt, a fixme tag will be placed and a more specific comment will be added in the changeset comment for more followup if needed.
