My thoughts in regard to issues raised today and a couple of
additional thoughts about using NSW LPI data in OSM:
1. The requested acknowledgement, as specified by LPI, applies only to
the information in the "Contributors" page of the wiki, not to the
tags of each data item. I think the source tag for each data item
should be shorter but accurate e.g "NSW Base Map, LPI" or "NSW Points
of Interest, LPI" etc.
As the data base is restricted to NSW Australia it may be sufficient to
simply state LPI, base map (or Imagery or POI etc) .
2. Like one other mapper, I am also a little uncertain about including
the date, however that is what has been requested and it is a small
price to pay for access to such rich data. Where a whole dataset is
imported on a particular date, it clearly makes sense but would seem
less practical where data is extracted on an ongoing basis. Unless any
clarification of this is received and since the stated intent of LPI
was to indicate to users where data may be not the most recent, I
suggest we use the earliest date on which data is taken from a dataset
but then add an amended date if, at any time, an update of the entire
dataset is imported into OSM. For example the current local government
boundaries are to be extensively re-drawn in the next 6-9 months and
it would be important to show whether any local government boundaries
imported from LPI are the soon-to-be-obsolete 2015 version or a
subsequent version.
3. The permission, as written, does not include the "six" mapping
site, although I note that clicking on the preview page for the NSW
Base Map takes one to the "six" site.. Our permission is for the
datasets on
http://www.lpi.nsw.gov.au/mapping_and_imagery/lpi_web_services/access_lpi_web_services
The NSW Base Map is one of the datasets offered on this page and,
although it appears to be basically the same as the "six" map, I think
we should be careful to refer to the dataset names on webpage
specified in the permission.
I think the 'six maps' is part of LPI ... certainly the URLs for the web
displayed maps show that. e.g.
http://maps.six.nsw.gov.au/arcgis/rest/services/public/NSW_Imagery/MapServer?f=jsapi
4. On the "Contributors" page of the wiki, I have included only the
NSW Base Map dataset as that is the only one I am using now. However,
as any of us starts to use data from any of the other datasets (such
as the NSW Points of Interest dataset), we must be careful to add the
respective dataset and specified information as a further dot point in
the relevant part of the "Contributors" page.
The LPI Imagery appears to be more normal to the earths' surface,
possibly taken at a lower altitude too - better resolution. This makes
it better to resolve the footprint of a building. So that too will be
usefull for some.
5. Some information in the different datasets is contradictory. For
example, some of the road names etc in the "NSW Points of Interest"
database are older obsolete names (different from those shown in the
NSW Base Map dataset) so we should recognise that even within the LPI
datasets there may be data that we do not wish to use. This may also
be good reason that source tags for individual data items include not
just "LPI NSW" but indicate the particular dataset relied upon.
Reluctantly agreed on the source tags :) . The base map appears to be a
few years old - shows a local private hospital that was knocked down
some years ago and is how some apartments.
I am interested if anyone has other thoughts on these points.
I note that I'm presently getting time outs through JOSM .. but not by
displaying their data on the web. Possibly a few people loading up their
servers, I'll wait to tomorrow and see what happens after, say, 10 am.
