I was speaking to Curtis Burisch off-list, who says that he can
probably do this checking automatically on the NGI data.
He says that he can not post to the list for some reason, but I am
waiting to hear back from him how it goes.
Otherwise I will start to undertake that manual check in small batches.
I have no idea how long it will take though. I predict ages, so if
people are willing to help, maybe we can co-ordinate our efforts.
There are in excess of 30 000 records in total, so if we can do it
(semi-)automatically, that would obviously be a major bonus.
I agree that being able to feed back any errors we turn up would be
good, and makes it more likely that we can potentially get access to
more data.

If we can feedback to DoE that would be fantastic. I would rather see
a
slower but more thorough process. Being able to contribute back to
the data
source would make for a good future model of contributing data and
could
encourage more contributions from other sources and government
departments.

Hi all,
I came across this the other day:
http://www.education.gov.za/EMIS/EMISDownloads/tabid/466/Default.aspx
It is spatial data for all the schools in the country. I am not
sure
whether
this can be used or not, but it might be useful nonetheless,
especially
for
rural schools. I am not 100% sure what the guidelines on importing
this
sort
of data are.
I informally asked the Department of Basic Education (DoBE) around
a
year ago if OpenStreetMap may use the dataset. They said we may.
I have also been in contact with the DoBE employee who maintains
the
dataset, he is eager for us to feed back updates/corrections.
The position data is unfortunately not reliably accurate for rural
schools.
Gerhardus and I have a basic repo with some work in it:
https://github.com/gjngeldenhuis/osm-za-schools
The data can be loaded into QGIS (or similar), but converting the
data
to OSM format would require work and coordination. (ogr2osm, buffer
excluding existing data etc)

Hi Grant,
I am wondering if this is the source of Google Map's school
positions.
Most of them appear to be fairly accurate, based on my wanderings in
the
sticks of KZN and the Transkei. At least, there is usually a school
where
Google Maps says there is one. Would simply (hahaha) checking on the
aerial
imagery that there is what looks like a school at places that the
data says
there is one be enough to constitute fact-checking for the
time-being? They
are usually quite visible as schools, in my experience.
If we can find a sane way of uploading them in small batches of 15
or 20
schools, that sort of checking should be doable, if very
time-consuming.
But, at the same time, we can feed that back to the DoE.
Will look at what you guys have in the github repo.
Thanks.
