Any mappers around me, feel free to contact me to share knowledge, experience or learning from each other or even go hiking / mapping together to learn from each others techniques and methods to improve our contributions.


How do I map: Tools: OSMAnd, Vespucci, GPSLogger and OpenCamera, Mobile Topographer for recording data.

Mobile Topographer I use for accuracy for offset determination - long-term GPS signal processing while not moving on an easy to be determined location on satellite imagery has been proven in my case to be much more accurate than simply GPS accuracy while walking around. So I usually rely on offsets from my own recordings using Mobile Topographer.

OSMAnd I use to record videos/photos/notes

OpenCamera I use for Photos

Vespucci I use for repetitive actions like adding addresses, house numbers, etc.

GPSLogger I use for recording GPX traces


I always map ONLY what I’ve seen with my own eyes, except for some past map-roulette edits - it’s for me important that I can verify all data myself personally.

I never use a single source of information but always included is the concept of:”my own eyes for verification”

Note not all data, video, photos, notes I record I upload. Sometimes I just have the phone with the recorded data next to my desktop monitor and work by using both screens instead of uploading first - depends on my mood how I wish to edit at that moment.

Additionally I may or may not do background research on the internet: - photos publicly shared by people on various platforms (the photo is copyrighted, not the physical reality on the ground visible on the photo!) - official FB pages of local establishments - FB-advisories and information shared by the local government of Baguio about the change of roads, parking areas, oneway or not, moving Public transportation stops, etc. - satellite imagery - there’s sometimes on some areas aerial imagery available, especially since this is a mountainous area even photos I can make from the roads can reveal a lot of data on lower areas and their alignment of houses, roads, etc. relative to each other which helps greatly to improve map alignments (if the proper angle and distance to the visible objects is considered of course) - sometimes I use information locals give me verbal, I ask a question and their feedback is then information I either can directly add to the map (like administrative boundary - or I use it in correlation with other information I record)

I NEVER use data from other maps!


Last but not the least:”I’m not perfect nor is my work, I do make mistakes. I sometimes discover myself months later I did something wrong - especially since the wiki.openstreetmap.org isn’t always up-to-date and sometimes multiple different tags/keys used for the same and sometimes I can’t find in the wiki what I’m looking for but on the OSM database I then find how someone else been doing it for years and then later I discover by coincidence on the wiki it’s obsolete and should not be used anymore - such errors happen.. Sorry for that, it’s not intentional and feel free to let me know if you find such”

I strongly oppose the concept of:”don’t let a mapper fix his own mistakes - instead just ruin whole sets of data and/or even all of his contributions.”

This is implemented by some local OSM communities and I strongly disagree from such methods. Teaching and improving should be the adopted concept, not judging and destruction.

If it’s deliberate misconduct by a mapper I can understand a tougher stance on this matter. But regular mappers who made an honest mistake - shouldn’t be punished by destroying their work - advise them and guide them to fix it instead of destruction of data.

This is “open data” after all.
