<p class="MsoNormal" style="margin-bottom:12.0pt"><span style="font-size:11.0pt">Dear Hajar and TomTom (mappers),<br>
<br>
In reference to my comments on your maxspeed=* mapping in Accra [1]. <br>
There are multiple frightening maxspeed=* from this mapping which are <br>
completely unverifiable. I also see roads which of course lead nowhere <br>
and were results of other organised mapping campaigns tagged with <br>
maxspeed=* without any further investigation.<br>
<br>
I would have expected that this kind of organised mapping is discussed <br>
publicly and documented on the OSM Wiki. As of 2024-08-23, there is <br>
only one road in Accra on OSM with verifiable speed limit of 100 km/h <br>
[2]. Seeing roads in dense Accra Central even with existing adjacent <br>
verifiable maxspeed=50 tagged with higher maxspeed=90/100 [3][3a] makes <br>
me wonder. I have also seen lower maxspeed values where there exist some <br>
street-level images to validate eg. way [4] (maxspeed=30) and Mapillary <br>
image [5] (street sign 50).<br>
<br>
TomTom's mapping team I believe is better aware and in the position to <br>
post-process all roads wherever and add whatever desired speed, see <br>
Default speed limits [6], but outsourcing to a bunch of newbies to add <br>
into OSM, is not what OpenStreetMap is about.<br>
<br>
As I have always commented on this list and elsewhere there is just too <br>
much useless data from many undocumented organised mapping activities in <br>
Ghana that needs to be deleted in the end, hence we don't want to see <br>
new problems that will never be fixed.<br>
<br>
The practice of setting up a series of maproulette or HOTOSM Tasking <br>
manager instance projects and letting it fix itself is not helping but <br>
continues take place from multiple actors in Ghana and elsewhere.<br>
<br>
Please kindly find the best way to undo all maxspeed=* resulting from <br>
this organised mapping campaign without damaging existing valid ones <br>
e.g. manually, contact DWG, etc.<br>
