Re: [talk-ph] GPS review on etrex 30 and 62sc
I'm using Etrex 30 for my mapping expeditions. However I cant compare to any handhelds as this is the first I had. So far so good with digital compass and barometer. Screen is highly visible even in bright sunlight. Battery (using NiMH AA) lasts roughly 20 hours of continuous use. Tracing can be selected for time (upto 1-sec) point trace or distance (upto .01km) has microSD slot. USB 1.0 interface (mini-usb) Waterproof until 1 meter -- Ervin M. *Schadow1 Expeditions* - A Filipino must not be a stranger to his own motherland. http://www.s1expeditions.com On Tue, Jun 11, 2013 at 2:56 PM, maning sambale emmanuel.samb...@gmail.comwrote: Dear all, Any experience using etrex 30 [0] or gpsmap 62sc [1]?

Nice! The surface type (concrete, asphalt) is good data we can add in OSM, unfortunately, the disclaimer pdf has very strict copyright restrictions.

Re: [talk-ph] DPWH 2012 Road Data
Clicking on Region IV-A on DPWH link: http://www.dpwh.gov.ph/infrastructure/Road%20Data/2012%20Road%20Data%20for%20Ipad/region_iv_a.htm Is it safe to classify Caylabne Road a trunk (an extension of Governor's Drive)? How about Naic-to-Mendez and the Tanza-Trece Martirez roads? Weird, Aguinaldo Highway Sta-Rosa-Tagaytay Road classified as secondary, yet Calamba Road is arterial?? can't be Declassify as trunk (back to primary) the pagsanjan-louisiana-lucban route? (road is too narrow anyway) Calauan-Nagcarlan route is just a minor road on OSM but looks like a trunk going all the way to Tayabas on DPWH's map.

I guess the dpwh's copyright restriction was just a copypaste thing. I'm not sure I can give you a straightforward answer since I am confused myself sometimes. :) There is a concept of derived database and produced work in odbl. Depending on how you use osm data and distribute the output, it may fall on either of the above category. In fact, the default map tile is not odbl but cc-by-sa. The wiki has sample use cases. I say let DPWH use it more on their projects silently, so that we'll have more proof..., and then it's easier to officially negotiate for sharing of government data in the future (give take arrangements). :-) I think government use of osm is what most of us want. I'm actually curious why they use osm over other webmap service. Is it easier to use? Nice cartography? Better data? How can we help them even further beyond using osm as a background layer? ___ talk-ph mailing list talk-ph@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-ph

Re: [talk-ph] ideas on importing deped schools db to OSM
Dear all, Just to update you on this. Upon random checking of some tiles, there are cases where the location is too far off. It was confirmed by Liana that in some cases, brgy boundary centroid was used when no actual gps survey was conducted. I will try to cleanup the data before we begin the import. Suggestions welcome.

For example, by provinces and then divide the data per province into smaller chunks like Ilocose Norte 1, Ilocos Norte 2, etc. I think chunks of 100 is much more manageable. I certainly don't think I can process 500 schools in 1 or 2 sittings. Here's a screenshot of the splitted data in 100 nodes https://docs.google.com/file/d/0B-2WZQ1DwK_xRFpKcHJyaEh6REE/edit?usp=sharing https://docs.google.com/file/d/0B-2WZQ1DwK_xa0pkQ2tpNmhacGc/edit?usp=sharing The ES shapefile is ~190 tiles. I suggest to add the upload=false XML attribute to the OSM files to avoid accidentally uploading it to OSM. Yes, the ogr2osm script adds this. But the splitter I use doesn't will investigate further. -- cheers, maning -- Freedom is still the most radical idea of all -N.Branden wiki: http://esambale.wikispaces.com/ blog: http://epsg4253.wordpress.com/ -- ___ talk-ph mailing list talk-ph@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-ph
Re: [talk-ph] DPWH 2012 Road Data
Well, there's a loophole in that provision. If what you get from the government is *pure data* (numerical coordinates, etc.), then you can't use it in OSM without permission. This is the idea behind the DepEd and DOH data we are getting/trying to get. On the other hand, if what you get is an image (e.g., map), then you are free to take facts that you can see when you look at the image/map. The Philippine IP Law follows the US IP Code in that facts aren't copyrightable. You can't use or distribute the map itself for commercial purposes without permission, or copy the creative aspects of the map (which are copyrightable) such as colors, styling, cartography, etc. without permission, for commercial purposes. But you can get facts that you have interpreted from the image and use that in any manner you choose because facts aren't copyrightable and the government did not give you that fact outright. Of course, we can just ask DPWH for permission.
