backpacking philippines's Diary

Recent diary entries

I pass by quezon avenue from West Avenue up to Araneta everyday and now I got good news and bad news at the busy intersection where jeepneys create a terminal at the corner blocking cars from turning right to araneta after the u-turn near sto domingo church.

with the start of construction, i'm looking for alternate routes, though I know one via Kaliraya (where I passed by twice already when i see heavy traffic ahead of araneta), the street's actually too narrow for a residential road due to presence of flea market, informal settlers, and lots of pedicabs and tricycles.

Kaliraya would have been a very nice alternate road if not for the pedestrians and pedicabs occupying the street making it like a one-lane street only where you risk your car being sideswiped by pedicabs or you hit slow moving pedestrians walking on the street.

another alternate route is via Roces then morato, e rodriguez then balete drive where you end up on Santolan or just via Gilmore to Ortigas Extension.

I love to experiment to test OSM routing (thus detect errors) but the routes are slow due to presence of jeepneys.

I think EDSA is still better and reliable, especially when it's raining :P

an unexpected request from wifey to drop by my new home in Cainta before heading home to QC made me think of a way how to get there on a route i passed by only a couple of times when i commuted from crossing to tanay to siniloan bfore paete

I only checked the roads some days ago on how to get there via the lower towns of rizal (morong, binangonan, angono, taytay et al) but not the excat route from angono to floodway

I blindly followed OSM and got me there without a hassle except heavy traffic at the intersection of east floodway, barkadahan bridge and hway 2000 due to lack of traffic signals or enforcer while people in the area just look around at the traffic jam.

i intend to explore again the lower towns and find stopsovers as I've almost run out of restaurants to try along my usual route to paete

lastly, i checked the intersections and roads i added along floodway via Bing and they're all there. need to add street names when i pass by again. missing roads are somewhere near Baras plus mis-tagged tertiary roads in Tanay that are more like service roads due to being narrow made only for trikes

for people asking me about my Garmin on my dashboard, i always tell them i bought it not for me but for my direction-challenged wifey.

Sine i had it about 1.5 years ago, i've updated roads to/from my own makati slice i.e. salcedo village: missing roads, turn restrictions, missing u-turn slots, no crossings and one-way streets...also eliminated better looking yet inaccurate for Garmin the corners of dual-carriageways meeting a single-carriageway road (know why? found out Garmin routing algorithm doesn't like turns...it looks for the primacy of roads but avoids turns and corners even if it's farther (garmin set to faster route, not shortest route). OSM shoudld depict such corners as a Y rather than a T or a cross.)

As i told wifey she won't get lost going to my office in Makati from Quezon City, the day came when she used my dear Sakura with her brother to fetch me.

I was wrong.

with OSM in had, she got lost that made me wonder why the so many times i've tested the route to my office with no glitches, even from different approaces and routes, except some portions where GPS signals affected by tall buildings.

Upon "interrogation" I found out she doesn't understand the numbers on the top left corner of Nuvi that indicates the distance before turning left or right while her brother is "scared" of the one-way streets of Makati and can't figure out the GPS instructions too.

Conclusion: it's just the usual USER_ERROR :P

lakbay Rizal @150

Posted by backpacking philippines on 6 June 2011 in English.

with the release by the DOT of the 27 rizaliana sites, i counted only three sites that i haven't been to

no back credits there, i need to re-visit them just to complete the stamps on my passport...

but I think I can complete it again
i have an upcoming trip to Paracale in CamNorte where I can pass by Daet again
I can book a flight to Dipolog to visit the shrines there.
Calamba is just an easy trip for me as well as Malolos, Antipolo and San Fernando, Pampanga

Cebu is regular on my list (or I can drop by once the trip to Loay, Bohol is finalized) while Iloilo I can probably just spend from my own pocket...

hmmm...let's see. it's all so easy on paper and yet so hard when priorities in life are changing :(

stamps on my rizal@150 passport and traces for OSM :P

I'm going to a baptism of a friend's daughter on saturday somewhere in paranaque and peeked in advance in OSM to compare the map furnished to me.

the roads were correct but some road names do not match. my friend's map was hand-drawn, not to scale but bear some names absent in OSM.

I've been to her residence two years ago when I got lost due to a wrong turn on France rather than on Russia and blamed the previous map given to me

this time would be easier since my friend took note of the inaccurate map comment thus the new one :P

but this time, I have OSM on my side, no problem going to the resort as I've added it already thru BING but I can't find Mary Immaculate Parish there :(

I went to San Mateo for a free trip to Timberland Heights on the mountains of San Mateo and passed by Commonwealth avenue and batasan (no routing errors here) as timberland is well mapped (except wrong name and road should be private)

only noticed missing u-turn slots on commonwealth between Tandang Sora and Batasan, about 4 or 5 of them while some are misplaced. These can potentially route incorrectly if you're going to some roads between the two points.

how was i able to spot them errors? It's just whenever I see u-turn slots, I glance at my Nuvie to see if it's there, most of the time, they're not there on the stretch I mentioned.

only the slots from UP to circle is correctly mapped (as i also frequent the place en route to/from Katipunan)

i downloaded the demo map of RG to look at camnorte but also noticed road data on paete. I was surprised at the detail of roads present on RG unlike the earlier demo version.

just my thought:

how can RG get a map of paete with street names? not that i mind but street signs in paete are a rarity unless you're a knowledgeable local (most locals don't know the street names but remember landmarks). No accurate map of paete can be found online except OSM and Google maps is still too full of errors.

anyway, lots of errors in tagging there as most streets are too narrow plus Manila East Road is mislabeled in RG (part of the old RG version, it should be J.P. Rizal Street). The Quinale Street there is also erroneous, forgot to correct it yet the error is also present on RG. what gives? :P

anyway, it benefits my hometown :P

with only the towns of Famy and Sta. Maria needing updates on their town centers, I think it's really Laguna with most detail for all provinces...unless of course i wasn't able to scrutinize the others.

I say Best mapped but not really complete...lots of work to do to improve present data as well as POIs, POIs and POIs. I'm trying to recruit other locals to join the fun to update and edit

kudos to all OSM PH mappers and thanks to Bing for the hi-res imagery. hope you include Famy, Sta. Maria and Siniloan towns in the next satellite image update :P

last weekend, i went to PICC and passed by bonifacio drive, blumentritt, avenida then back via espana. only noticed a few minor tweaks

already corrected the routing in sta cruz going to lawton and it's now flawless with the proper roads prioritized plus the one-way roads. Note I can't make routing avoid the intersection of recto and avenida due to heavy traffic there but making a turn to Mapua St, OSM will show you the correct alternate route.

there are missing u-turn slots on bonifacio and quezon avenue though that i will add later, i can't now since i disabled Flash on my browser as it's making my Firefox 4 crash (even my old firefox 3.6)

also noticed Mabuhay Rotonda is now a roundabout again but there seems to be a no-through traffic from Mayon or E. Rodriguez that makes it only for u-turn purpose. have to confirm it later though it's not my regular route so it may take time.

my first day of my 2D/1N trip to davao city, probably my 4th in this southern city

davao city's fairly mapped with streets i passed by todaw but noticed several errors when i tried to route to my destination along jp. laurel

as with most routing errors i encounter, it's a single carriageway mapped as dual-carriageway (or the other way around)

JP laurel for one, davao's main artery from the airport is one (the center island is only present near the interchange and in the vicinity of victory mall). there are some more i noticed that needs to be converted to single-carriageway...will just tag them in openstreetbugs later

most of the ways here are tagged secondary but i observed should only be residential or minor, tertiary at most...

was editing parts of Cainta, adding roads from Bing and upgrading roads to effect proper routing when the dreaded error appeared (blank screen with the exclamation mark on Potlatch 2)...

I wasn't able to save, hitting S didnt' work, as i've pretty much traced mostly residential roads plus some major roads around countryside, midtown subdivisions et al...

just call it a day...i'll redo if i find myself not feeling lazy :(

i'm going there to cainta again tonight for a friend's birthday and will just obeserve missing roads on OSM

added several traffic signals at madison and mckinley and several POIs on ortigas

note the crossing of Xavier and Roosevelt needs to be checked if really present, I don't remember having them there (it has an effect on routing, again)...

note the missing U-turn slots, one is underneath the Ortigas flyover, routing errors again.

also, a no right turn at the corner of Wilson, you're required to use the service road, it's not mapped correctly, ive yet to use it, that's why i don't have traces.

Vigan, Ilocos Sur

Posted by backpacking philippines on 21 February 2011 in English.

finished another installment of the heritage town of Vigan. Added new roads, POIs including the hidden garden in Bulala near the airport. Intentionally passed by unmapped roads just to gather tracks.

this city used to be just a three road map, something unusual in OSM for a supposedly tourist area...

the basic road network can be completed once hi-resolution imagery from Bing is available so keep your fingers crossed.

note that many roads in Vigan are one-way from 7am to 7pm but I did not tag them as one way so be careful.

Luna, La Union

Posted by backpacking philippines on 21 February 2011 in English.

added the main link from Bangar to Luna town. passed by the town, from vigan, in search of the Luna watchtower that i found in ruins and a tree growth inside the old brick spanish watchtower. added our lady of namacpacan church and the monument of Antonio Luna

I never knew Bing existed in the area...at least the main road link is there. hoping for updates to Ilocos Sur and Vigan so I can complete the map.

Puerto Princesa, Palawan

Posted by backpacking philippines on 21 February 2011 in English.

visited Palawan just yesterday and OSM was a surprise. I only noticed minor bugs including the new south road that go to Iwahig (it's tagged in OSM as Provincial Road when street signs say it's National Highway (again)) and tag the old road as no_access. I will add missing traffic signals and a turn restriction. the intersection go fernandez and rizal avenue haave about 50 meters of center island but it won't affect routing since there are no other roads, unless you're going to the establishments near the corner

even the private subdivision I stayed at is mapped correctly. the part of Brgy Kamuning need update...the islands of Honda Bay need to be renamed to local names as how the locals call the islands...

the road network is about complete, only the POIs need to be updated...even the monkey trail, the trek from Sabang to the underground river entrance, is in OSM, nice work!

will add my few updates later

i browsed my favorite haunt Quiapo and noticed several streets there with glaring orange colors, many of them are the narrow streets that can even be tagged service roads or living streets due to being almost impassable.

added the missing link from evangelista to recto (back of isetann)...not yet sure but i think it's also a one-way street but will verify, only added the traffic lights (evangelista is the street with lots of stores selling generators, pumps et al...it's also where the quiapo-divisoria-north harbor jeeps pass and usually too crowded, don't pass there unless you're going to the inner streets of quiapo)

also noticed inconsistencies for nearby sta. cruz and binondo areas...
will rationalize them later

since i've fixed routing from roosevelt munoz to makati, looking beyond my home turf and usual route for possible errors. i usually find routing errors from dual-carriage roads with missing crossings and u-turn slots. last time i found them on the short stretch of Samsom road and McArthur highway (still uncorrected)

this time I noticed Congressional avenue has missing slots too. I already added the missing road link to cagayan with a traffic light (with a possible turn restriction but i've yet to add pending verification) but there's one missing u-turm slot used by Proj 8 jeeps to get to Shorthorn. will look for it the next time i go to Holy Cross in Novaliches or probably peek into Bing to reveal it for the slot usually has a jam of vehicles waiting to make the u-turn

i've been reviewing the map of my home province and it seems only the town centers of Famy and Sta Maria are not mapped. all the others are present thanks now to Bing that provided hi-res imagery. Sta. maria needs lots of clean ups too but there's no Bing imagery there as well as Siniloan and Famy.

I've been to Sta Maria twice. the second time i tried to find the alleged old stone church there only to be dismayed at a new structure, so much for false reports or outdated online info.

i'll start looking for other Laguna locals to help in making Laguna the most mapped province of OSM PH :P
