For me, accuracy is important in OSM but for me. OSM is a free and sharing tool which anyone can update errors, add or even delete until such time we can correct it.
I agree for the option 2. thats why OSM created for us.. PRO or amateur...
thanks.

I really don't understand why some are insisting that I wanted survey grade accuracy at the very start of the series of my posts. Please don't teach me on how OSM works. I have been in in CAD/Civil/Survey/Mapping/GIS business for more than 20 years already. I do understand that OSM sustainability will be at stake when free differential correction becomes available in the Philippines. This is not my own opinion. This is from Computer Science standpoint.
I am only suggesting for Mapping Pros to come in in order to sustain OSM. To those who are turned off of my suggestion according to Eugene, I am asking of what you're after in OSM. If sustainability is a concern of yours, then what path are you going to take?
Come on guys.

arnel,

When dgps becomes available, then surely we will use it. European
OSMers are now using egnos to update their own patch in OSM.
For the meantime, we will use whatever tools (mostly free) that are
available. If somebody gives me 20K PHP, I can rent a DGPS unit (for
a week) and bike around my own OSM patch to make it more accurate.
> If sustainability is a concern of yours, then what path are you going to take?
Let me share some of my thoughts re:sustainability vis-a-vis OSM principles.
1. OSM data gets better by iteration - that's the basic principle of
a wiki. If the data right now is inaccurate, we can edit it again and
again until it gets better and better.
2. No data or edit is immutable - again a very basic wiki principle.
If someone added data, anyone can correct, improve, delete them.
Given the above principle, I'm sure OSM is more sustainable than other
mapping project.
> Come on guys.
Yes, I think we are beyond the "turned-off" phase now. We would love
to hear what you can contribute here being a mapping pro for 20 years.
Welcome!

I think we should mark entire farms as one polygon as much as possible and
not separate individual "paddies" as their own polygons. The dirt paths and
irrigation canals are still part of the farm, right?

No I'm not marking individual paddies. Maybe my message was a bit confusing.
The SPOT5 has a pix res of 10 meters. I usually map a farm polygon
when there is obvious subdivision between adjacent farms like large
irrigation canals. This is usually visible in the image at around 4-5
pixels (roughly 40-50 meters). The gap size seems sensible enough.
Whenever possible, I am also excluding residential areas around the farms.
Is this OK?
Sorry I can't provide a visual example (the data is on another
machine) and I haven't added anything in the OSM database just yet.

hi,
We are pleased to announce the new release (20091114) of the OSM-PH
Garmin GPS Map. ?This release is another important milestone for the
OSM-PH Garmin GPS Map project.
This the third release who graduated from our new release cycle. ?The
general release cycle is every two months (1 month for pre-release
testing and 1 month for the regular release). Thanks to all those who
tested and provided feedback.
What's new in this release
?2009-11-14
?- data as of 20091114, thanks to all the 350 contributors
?- 45,000 ++ kilometers of roads
?- sea polygon
?- beta of address search
?- changed codes for some POIs to enable search
?- new map style added from Rally
?- compiled with mkgmap version 1334
Known bugs:
?- Full address search may not work as expected
?- Some islands are "flooded" (coastline data issue)
?- POI icons not visible using 3D mode in some units
?- installer available only for MapSource
See my blog for a visual log of this release:
http://epsg4253.wordpress.com/2009/11/14/new-osm-ph-garmin-map-release-nov-2009/
Before installing the new maps, please remove the previous OSM-PH
Garmin GPS Map following the instructions here:
http://esambale.wikispaces.com/remove_mapsource_mapset
To download the maps, go here:
http://esambale.wikispaces.com/osmphil_garmin
Other experimental GPS maps are also available:
http://esambale.wikispaces.com/osmphil_garmin#toc5
As usual for data problems, go fix it at:
http://www.openstreetmap.org.
For bug reports, post a message either at the wiki discussions page:
http://esambale.wikispaces.com/message/list/home
Or via our svn/trac site:

If someone (I'm thinking of you guys at neuraltech) can do a similar
prototype, I can arrange a hookup to a GPS base station.

@maning, I already created prototypes similar to that.
Do you need a GPS that can be hooked to your pc via USB/Serial port? We
can design something for you.
Best,
murlwe
