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.
