Just a humorous aside.
At the height of Pepeng's triple assault on Northern Luzon, I was
asked by a volunteer, "Sir Jun, di namin makita sa Google Map ang
Abra-Kalinga Road." He was assigned to pin NDCC landslide events that
day, and was spending so much time looking for the Abra-Kalinga road.
Since I'm from Abra and have visited Kalinga quite a few times, I'm
somewhat familiar with this road. So we shifted to Satellite image
mode, zoomed as inward as possible to recognize more familiar terrain
and ground features, if not the road itself, and I tried to
approximate the road's twists and turns with a segmented-line tool,
thus connecting Tabuk to Bangued. It's still there... an artifact of
our quite rudimentary level, for now.
I was quite surprised myself at the paucity of road and village info
in these parts, since I seem to recall that in Google Earth, there was
a wealth of point markers at the barangay and village level, which I
could not see in Google map.
I'm really quite interested in map matters (it will be the subject of
my next blog).

Hi Aileen and Serge,
If you want, you can use the OpenStreetMap (OSM) tiles as another base map layer (e.g. like the Map, Satellite, Hybrid) (but you'd have to use the Google Maps API directly instead of using the Google My Maps service).
OpenStreetMap is another volunteer mapping project like Google Map Maker. Volunteers there generally use GPS loggers to trace out roads and the project has more map coverage in some areas where Google doesn't have high-resolution satellite imagery like eastern Laguna and some Cordillera provinces.
If you know Google Maps API, check out this page to see how to access the OSM tiles: http://wiki.openstreetmap.org/wiki/Slippy_map_tilenames
To see if OSM data is suitable for your use here are some comparisons:
Dagupan City is better in Google Map Maker:
http://tools.geofabrik.de/mc/?mt0=googlemapmaker&mt1=mapnik&lon=120.34201&lat=16.04152&zoom=13
Baguio City is better in Google Map Maker:
http://tools.geofabrik.de/mc/?mt0=googlemapmaker&mt1=mapnik&lon=120.59521&lat=16.41089&zoom=15
Sta. Cruz Laguna is better in OSM:
http://tools.geofabrik.de/mc/?mt0=googlemapmaker&mt1=mapnik&lon=121.41335&lat=14.27436&zoom=13
San Pablo City is better in OSM:
http://tools.geofabrik.de/mc/?mt0=googlemapmaker&mt1=mapnik&lon=121.32391&lat=14.06948&zoom=14
I think you should use both and switch to one or the other if there is better map coverage.
Hope this helps,
Eugene
