<div style="font-family:Arial;">A month ago, we celebrated the news that OSM now has approval to use the PSMA Administrative Boundaries and there was some discussion, including the need for a proper import process. I am willing to start adding some boundaries in areas with which I am familiar/interested but I am waiting for the proper import process to be determined. I am not aware if anything has been done in regard to a plan to import this data. If so, please guide me. If not, I propose the following:<br></div>
<div style="font-family:Arial;"><br></div>
<div style="font-family:Arial;"><br></div>
<div style="font-family:Arial;">Individual mappers download most recent data from <a href="https://data.gov.au/dataset/psma-administrative-boundaries">https://data.gov.au/dataset/psma-administrative-boundaries</a> and add/check data in their areas of interest and/or when they have time. (Andrew Harvey has provided a script <span class="text-gray-dark mr-2">to assist working with PSMA Administrative Boundaries Data</span> and there is a link on <a href="https://wiki.openstreetmap.org/wiki/Australian_Data_Catalogue">https://wiki.openstreetmap.org/wiki/Australian_Data_Catalogue</a>)<br></div>
<div style="font-family:Arial;"><br></div>
<div style="font-family:Arial;">Administrative boundaries in NSW, SA, VIC and ACT be modified instance-by-instance if there are discrepancies that require updating. Where there are discrepancies, the most recent data is usually preferred . If there are concerns about accuracy of the most recent data, further consultation with other mappers or relevant government boundary authorities would be appropriate.<br></div>
<div style="font-family:Arial;"><br></div>
<div style="font-family:Arial;">In QLD, WA, TAS and NT : LGA and Suburb/Locality boundaries be added one at a time, integrating with existing data where appropriate. Previous data from unauthorised sources be deleted or the authorised source be added if the data is accurate.<br></div>
<div style="font-family:Arial;"><br></div>
<div style="font-family:Arial;">LGA Boundaries continue to be tagged as admin_level=6<br></div>
<div style="font-family:Arial;">Suburb/Locality boundaries be tagged as admin_level=10<br></div>
<div style="font-family:Arial;"><br></div>
<div style="font-family:Arial;">In both instances source=PSMA_Admin_Boundaries_August_2018 <br></div>
<div style="font-family:Arial;">(or whichever date is applicable to the most recent data being used)<br></div>
<div style="font-family:Arial;">This source information may seem unwieldy but provides accuracy and completeness of information.<br></div>
<div style="font-family:Arial;"><br></div>
<div style="font-family:Arial;">Administrative boundaries NOT be attached to other ways such as creeks, rivers, roads, etcetera so that the other features can be modified as needed without affecting the administrative boundaries which are generally static.<br></div>
<div style="font-family:Arial;"><br></div>
<div style="font-family:Arial;">Multiple administrative boundaries (including national_parks and government approved protected_areas or state forests) be mapped on a single way, where appropriate, and with multiple relations attached to that single way i.e. a single way could form the boundaries for localities, LGAs and a national park, if appropriate in the particular location.<br></div>
<div style="font-family:Arial;"><br></div>
<div style="font-family:Arial;">Electoral boundaries NOT be added at this time.<br></div>
<div style="font-family:Arial;"><br></div>
<div style="font-family:Arial;">Other boundaries which have been discussed, such as regions and indigenous areas, NOT be added as part of this particular project unless they are LGAs or Suburbs/Localities (some indigenous areas may be identified as protected areas or defined localities or LGAs, in which case they are added and identified on that basis). Mapping of regions could be further discussed separately if required. They are usually not defined by legislation and therefore usually not "administrative" in the way that LGAs and Suburbs/Localities are legislated.<br></div>
<div style="font-family:Arial;"><br></div>
<div style="font-family:Arial;"><br></div>
<div style="font-family:Arial;">Comments and feedback, please.<br></div>

<div>Quoting their email, "The Australian Government received great encouragement from PSMA Australia Limited to make the AB [Administrative Boundaries] data more accessible. Many thanks to OSM for your ongoing global open data efforts."<br></div>
<div><br></div>
<div>Others more active in working with admin boundaries in OSM might be able to comment further on my analysis, but I've taken a look at the current OSM data from a planet extract[3], using osmium tool to extract administrative boundaries[4]:<br></div>
<div><br></div>
<div> osmium tags-filter australia-latest.osm.pbf nwr/boundary=administrative -o osm-admin-boundaries.osm.pbf<br></div>
<div><br></div>
<div>Then converted to GeoPackage to open in QGIS to compare to PSMA boundaries:<br></div>
<div><div><br></div>
<div> ogr2ogr -f GPKG osm-admin-boundaries.gpkg osm-admin-boundaries.osm.pbf<br></div>
</div>
<div><br></div>
<div>The admin_level values for Australia are defined as[5]:<br></div>
<div><br></div>
<div>3 n/a<br></div>
<div>4 State or Territory<br></div>
<div>5 n/a (but used in Victoria for regions[6])<br></div>
<div>6 Local Government Area (eg Shire/Council)<br></div>
<div>7 District or Region (e.g Perthshire, Fitzroy, Canning, Greater Sydney, Greater Melbourne, etc.)<br></div>
<div>8 Postcode<br></div>
<div>9 Suburb and Locality<br></div>
<div>10 Suburb and Locality<br></div>
<div><br></div>
<div>(not sure why the split across 9 and 10...? but it looks like no data for 9 and all suburb/localities are marked as 10, a seperate discussion but perhaps they should be 9 and smaller neighbourhoods be in 10?)<br></div>
<div><br></div>
<div>PSMA Admin Boundaries provide (for Australia wide Shapefiles see [7] built from [8])<br></div>
<div><br></div>
<div>Commonwealth Electoral Boundaries (I don't think should be included in OSM)<br></div>
<div>State Electoral Boundaries (I don't think should be included in OSM)<br></div>
<div>State Boundaries<br></div>
<div>Local Government Areas<br></div>
<div>Suburbs / Localities<br></div>
<div>Town Points<br></div>
<div>Wards<br></div>
<div><br></div>
<div>admin_level 6 LGAs<br></div>
<div>It looks like NSW, VIC have complete LGA coverage already aside a few minor differences, but NT is patchy and TAS, QLD, WA are almost non-existent (ACT doesn't really have LGAs it's all managed by the Territory). SA is missing a few LGAs which exist in the PSMA data.<br></div>
<div><br></div>
<div>admin_level 7 is a mixed bag, but the PSMA data won't help here<br></div>
<div><br></div>
<div>suburbs/localities<br></div>
<div>NSW, VIC, SA all have pretty much complete data in OSM but there are a number of differences with the PSMA data which should warrent investigation and correction.<br></div>
<div><br></div>
<div>ACT I think has good existing data (in the PSMA data in suburb/localities there are both levels, eg. Canberra Centre and Parkes), but the districts have a slightly different name format.<br></div>
<div><br></div>
<div>All other states are empty in OSM.<br></div>
<div><br></div>
<div>Keeping in mind that we have state data for admin boundaries in VIC (VicMap), NSW (Spatial Services), ACT (ACTmapi) and SA (<a href="http://data.sa.gov.au">data.sa.gov.au</a>) already.<br></div>
<div><br></div>
<div>So there does appear to be a lot of data missing in OSM, which licensing wise we could bring in to OSM. So I guess the question is should we and how should we do that. Is anyone interested in working on this? If people are, I think it should go through the proper import process (discuss first, identify the process and then execute).<br></div>
