OpenStreetMap

footways, paths and shortcuts

Posted by ianlopez1115 on 8 September 2009 in English (English)

It has been almost a month since I made my last diary entry. Since that time, I'm now looking for more "shortcuts" to my neighborhood. One route is considered a bit safe, since you only get to ride on a small vehicle that traverses along some supposedly abandoned railways, then walk an estimated 200 meters to the gate of Nefortville, then you walk towards your destination (which can be either your home, or the place where you used to study, which is not far from my neighborhood). Another route that I've discovered is from Mareflor/Marleflor street to Parkview street in nearby MariƱo Subdivision. I only used the latter route once, because I thought that the said route would lead me to the train tracks. However, some stretches of the path are either dangerous or treacherous. Especially in the part close to the banks of the Malinao River. I nearly slipped while approaching the river through some muddy steps. Thanfully, I didn't slipped, and half of my body and the GPS nearly got wet (the GPS still works as of now).

Just last week, I discovered another footway near my neighborhood, and it led me to some footways in nearby San Lucas 1. While mapping, some local saw me and asked "Why are you doing here?" I told her that I was mapping the place, and mark places where to go and not to go (including her house, which is now marked as a no-go [a.k.a. access=private] area,), and to find out if that footway goes to some place. She told me that no footways to the other side existed a long time ago. To end the "conversation", I said thanks and apologized for causing this kind of trouble. I do hope that this won't happen again. Other than that, it's just discovering new footways, adding some housenumbers and POIs.

And last Saturday, my father and I rode on a motorcycle and it was raining. We then decided to take a shortcut back to our neighborhood. Along the way, he discovered a flat tire at the back, which was fixed an hour later. Flat tire or not, the track is now in OSM.

Barely an hour ago, my cousin saw OpenStreetMap and told me that there are various "shortcuts" near my place that is not yet on the map. One foot-only route is from somewhere in Car Dil Village to the back of BLISS Chapel, while another shortcut is from somewhere near Unityville hamlet to a certain place between the villages of San Lucas 2 and San Pedro. I'd love to those places and map it, but I have to somewhat prioritize downtown San Pablo City, which probably needs the map more than I do.

I bought a travel map for the region covering San Pablo, and its coverage of the place was not as accurate as our coverage. It probably copied some areas from a local map and added some names to the streets that they copied. In some POIs, they even mixed up the names of two shops, and turned it into one shop. One POI's location is on the wrong side of the road. Another one is about 250 meters north of its supposed location. At least 3 POIs have the wrong names. Even worse, some places listed on that map closed shop or were renamed or something.

The only good thing about it is that I can compare its coverage to the local map's coverage, then compare their coverage to OSM's soon-to-be superior coverage. Maybe I should go to more places within the city, just to map those areas. Or invest in a RC helicopter and take aerial images for editing.

If you know there are some ways and you don't have the time to track them you can set some marks at http://openstreetbugs.schokokeks.org/

@Zartbitter I use OpenStreetBugs, but it's on the appspot.com subdomain.
