My opinion that we need to check by our own local maps and some data are duplicated too. I tried it here sa aming LGU, merong mga inconsistency eg, spelling, coordinates and duplication. But it helps kasi me mga label ka na sa map.
Is GNS-NGA is open source?
thanks.

BSWM data is sometimes quite wrong. I had to delete some of those roads that
clashed horribly with the traces we collected for GMA, Cavite.

This is a pretty tough issue. Imports are contentious in some sectors of the
international OSM community. But for the Philippines where we don't have
much data to import anyway, the question boils down to whether we prefer no
data at all over poor data.

GNS in particular seems to be problematic with entities below the municipal
level as demonstrated by Ax.

I think that we should hold off on importing them for now. Maybe in the
future that data will be improved. In the meantime, there are tons of things
we can do to improve the existing data. Keep right and OpenStreetBugs
provide tons of data problems alone, and there are some residual sawtooth
coastlines remaining.

I know data maintenance and improvement is not as fun as importing virgin
data but my personal opinion is that we should try fixing the existing data
first before adding more data that themselves needs fixing too.

What do others think?

Since you've mentioned the tendency to be contentious, hopefully this
one won't go overboard :-)

So that +1 to "No imports for now".

By this statement, I assume you are referring to the GNS data.

In some cases, imports can be very useful.

After importing several data into OSM, I am now more on the "no
imports" camp too.  However, I'd rather initiate meetings with the
Marikina government to arrange imports of housenumbers than collecting
them all by myself.

I already made re-alignments since i'm familiar with the road network
and also deleted spurious roads or added FIXMEs. I just have to
re-trace when I come home next month or during the long break in
December.

at least I won't find myself driving "off-road" again when i'm "lost"
in that part of the world

might also drop by and explore Sta. Maria. I went there years ago to
look for the old church only to be disappointed by a new one.
(Internet's really full of misinformation). I hope to trek to the
waterfalls if I can sneak from wifey who's quick to warn me not to be
so adventurous hehe

I explore, therefore I blog and map.
