I have been concentrating on Samal Island in the Davao Gulf just
offshore from Davao City and have done a few farm roads around Davao
on the mainland. Samal Island only had a few roads on the map but I
have been able to add most of the existing roads. Most is dirt track
roads - even the main highways so I do most by driving my old Land
Cruiser and using the tracks from the GPS.
I do have a problem that maybe somebody can help me with. Access to
Samal Island with a vehicle is via vehicular ferry. I have tried may
ways to define the ferry route but no matter what I do the GPS will
not navigate if I select a destination that includes crossing from the
mainland to the island or visa versa. Can anyone suggest what to do?
I have been in Hong Kong for a few weeks but hope to get back to Davao
in a week or two and continue with the map.

Hi guys,
Once we are done with the large islands, the next step is to do the
smaller
islands. Ian Haylock has helpfully provided the PGS coastlines[1]
for the
Philippines last year[2] which he edited to combine ways. PGS
itself was
automatically generated by a software by analyzing the Landsat
imagery.
Unfortunately, Ian's file was hosted on a free file server and has
now
expired but I think several people on the mailing list managed to
download
it.
I tried opening the file last year in Merkaartor but my old laptop
couldn't
handle the data. Now that I have a 4GB-RAM laptop, loading the data
into
Merkaartor is very manageable. Using the PGS coastlines is much,
much easier
than tracing Landsat by hand. I tried this with Homonhon Island and
editing
is way faster than actually uploading it[3]. Hehehe. What I did was
to
delete the SRTM-derived coastline[4] and replace it with the PGS
coastline[5].
I think uploading the PGS coastlines is better for the smaller
islands. I'll
see what we can do to have the PGS coastlines (55MB) uploaded
somewhere.
