[Talk-us] how can we fix anonymous spam comments

[Talk-us] 2484 oneway roads in Philadelphia

[Badita Florin]

While writing a article about how to create a translation file, to use in
Cygnus 
Conflation Engine, I had chosen Philadelphia as a example.

And I have seen that many of the ways that should be added as oneway are
missing in OSM, but are present in the Open Data Portal
After running with Cygnus, I have decided to also see how many of the
oneway street are in the Open Data Portal, that we don`t have in OSM.

And the results were that much more streets that expected are missing in
that city.
In total, Cygnus detected *2484 ways that don`t have the oneway tag added
in OSM*

It`s not my priority now at Telenav to add them, being a side project, but
i`m thinking that if I put the data online, somebody could be interested in
this, they can verify them and add them to the map.

Also, *if you have want to run this in another city, create a translation
file and I can run it for the city that you are interested in. *

You can download the file from here https://drive.google.com/drive

Re: [Talk-us] Comparing Tiger 2017 dataset with OSM in a automatedway.

[Badita Florin]

I started processing, State by State, the Tiger 2017 dataset, because i get
less errors from overpass this way then if i process in bulk of 10 states.

The first state is Alabama.It took around 5 hours to complete,and it shows
over 20.000 possible ways that are not added in OSM.
The total length of the ways is 5042 km, or 3133 miles.
The xml size is 36Mb, and can be found in this folder.
https://drive.google.com/drive/folders/0B7aOUf0DFRnLU3hUWFNuS05JS2c?
usp=sharing

There are 5 35x35 miles tiles missing from the data.

Be mindful that this is the raw output, and even if Tiger 2017 is better
then older versions, there are still a lot of bad data in Tiger.

I expect more then 50% of the data to not be good for mapping into OSM.
Also, you can filter this data-set and keep just the road with the names,
that could be more important roads compared to the ones that don`t have a
name.

@joe, regarding the dataset for the twin cities, if you can create/provide
a translation file for the shapefile, i can run it and post the results in
the folder.

[Talk-us] Comparing Tiger 2017 dataset with OSM in a automated way.

[Badita Florin]

Hi, i wanted to ask if there will be interest around comparing TIGER 2017
with what we have in OSM, using CYGNUS, in a automated way.
http://www.openstreetmap.org/user/mvexel/diary/36746



On top of cygnus, i have developed shgp2cygnus, were you can place any
shapefile, any size, you provide a translation file, and, in the end, you
get a list with all the ways that are in the TIGER dataset, but not in OSM.

This would be something useful for the community ?



I don`t know if somebody is already doing something similar, or what is the
status ? Were can i read more ?

I knoiw that the TIGER 2017 Overlay in JOSM shows in red the roads that are
not in OSM, but are in TIger 2017.

But I don`t know were to read more, and if the data is accessible to
download directly, not just show as a WMS Layer.



It will take around 7-14 days to process all USA”
