Hi Totor,

Welcome to the family. :-) 

I've done a bit of mapping in Cebu over the last year or so, but not much 
actually in the city. I did a lot up north, on a holiday to Malapascua island 
(which you should visit by the way - a lovely beach getaway), and then filled 
in a few of the other roads from an out-of-copyright map Maning slipped me. 

As the map at the time was virgin territory (well compared to Manila anyway), 
then I was focusing mainly on getting the roads in and relocating the towns and 
villages, which were often several KM out of place. I didn't pay much attention 
to the types of roads, figuring someone like yourself would be along sooner or 
later to tidy up. So anyway, please feel free to go ahead and re-classify roads 
however it makes sense to you. 

Some of the roads I put in from the out of copyright map need to be verified. I 
think these are tagged with source=50k map or something like that, and they'll 
have no names. But once again I felt that putting any roads in at all is better 
than no roads, as they add a framework that people can add to. As the satellite 
imagery in Yahoo is rather poor for Cebu Island, then the framework of roads 
and GPS traces is pretty much all you have to work with for now. 

As for classifying the roads, I don't think the classifications as envisaged by 
the OSM originators in UK have much relevance to the Philippines (what's a 
trunk road for example here?), but I figure the most useful thing we can do is 
to classify in terms of importance, which gives a sense of the road network. 
Clearly there are some roads in the Philippines which carry a lot of traffic, 
and are very important, but which would probably only be classified as 
secondary or tertiary roads in Europe. So I tend to think in terms of ... 
Primary roads carry the most traffic, followed by secondary, followed by 
tertiary. That kind of thing ...

I'm probably going to get some reaction from the forum for this ... like all 
families we have our disagreements! But when I'm mapping I tend to think in 
terms of What is going to be most useful to people using the map rather than 
How exactly can I follow the mapping rules. 

In the case of Cebu right now, my feeling would be to get as many roads and GPS 
traces in there first, and then figure out the minute details of classification 
later. Once the road framework is in there, then people without GPS units can 
go ahead and fill in all the buildings and Points of Interest. 

My 2 centavos only ...

 appropriate.
 
 Any suggestions how to deal with all this ?

totor,

This is what I think is the proper tag (based on your description)

This should be:

trunk or primary
lanes=4

 The Cebu North road, really gets narrow at some sections when going south, 
 and would not be considered a main road abroad in those sections...
Split the road to where it is primary and residential.

 The South (SRP) road is now mapped as a single motorway. It should be 2 one

I guess this should be trunk with two parallel ways
with the tags
oneway=yes
lanes=3 0r 2



keep on mapping

2009-05-29 Thread Totor Osm

Hello everybody,
and thanks for the welcome...

For those who don't know me yet, (I guess all, except maybe Maning with who I 
already exchanged some mails) I'm a Dutch guy, living in Cebu city since 
several years now, and enjoying it much here.
I recently discovered openstreetmaps, and found it worth contributing to.

Next week I'll go back to Holland for my yearly holiday, so my mapping in Cebu 
City will pause for a while.

When I'm back, I'd need some clarifications, or guidelines, on how to classify 
the roads here in Cebu. I have difficulties in relating the guidelines about 
the tags to the reality.

Right now, there is primary roads, and residential roads mainly. I don't know 
how to improve this, since some main large roads (like A.S. Fortuna) don't even 
have a dividing line (this means it is 1 lane only ?) but the trafic is driving 
on 4 lanes (2 each side)...

The Cebu North road, really gets narrow at some sections when going south, and 
would not be considered a main road abroad in those sections...

The South (SRP) road is now mapped as a single motorway. It should be 2 one way 
roads... 3 lanes each if I remember well. But can it be a motorway road ? It is 
the closest to a motorway I ever saw here in Cebu, but I'm not sure there is a 
hard shoulder, there are many intersections and traffic lights, often tricycles 
also ride there... I guess a trunk road would be more appropriate.

Any suggestions how to deal with all this ?

Happy mapping!

Totor

Hi new list members,

Welcome!  I somehow lost track of new members of this list, but I
think we are getting new subscribers every week.  I welcome you all to
the OSM-Philippines mailinglist.
