Philippines/FAQs for PH data

This page is a mirror of an external markdown pad, documenting the de facto status of these issues and concerns by the OSM local community in the Philippines, mainly in previous channels discussions in the mailing list, and Telegram, and primarily for contributors who are new or unfamiliar with local conventions.

Frequently Asked Questions about data sources for OpenStreetMap contributors in the Philippines

What is OpenStreetMap?

OpenStreetMap (OSM) is a global mapping project, with the goal of providing free and open geographic data to anyone, without any legal or technical restrictions.

What the FAQ is for?

Rolling back problematic imports are costly, in terms of time and resources, for many small communities like ours. We hope to avoid this, by documenting the common or significant issues our LoCo has encountered.

How are OpenStreetMap data regulated?

Data contributions to OSM are governed by the Contributor Terms between the contributor and the OSM Foundation (OSMF). Under said terms, the OSMF then provides the content ("data") worldwide, under Open Database License (ODbL.) A plain summary of ODbL is available here.

What sources can I use to make maps from?

You may add data based on your personal knowledge and local surveying. You remain the copyright holder of your data, but by agreeing to contribute to the OpenStreetMap project, you also grant certain rights to the OSM Foundation (OSMF) under the Contributor Terms.

In addition, OSM has permission to use or derive data from imagery coming from sources like Bing, ESRI, KartaView (formerly, OpenStreetCam) Mapbox, Mapillary, Maxar, and OpenAerialMap

How about using Philippine government data and maps?

Although work of government is considered as "public domain", and ineligible for copyright under section 176 of the Republic Act 8293, the same paragraph states that prior permission is required for commercial use.

This "public domain" restriction by the Philippine government on any work of government makes them incompatible with OpenStreetMap's Open Database License (ODbL). As stated in the OSM Import/ODbL Compatibility wiki page (emphasis is ours):

Note that any license that (sic) with commercial use prohibition (for example "The works shall be used only for nonprofit purposes.") or forbidding modification (for example "It is prohibited to modify the work, or change it to create a secondary work.") is clearly incompatible with ODBL.

Futhermore, the "non-commercial use" provision goes against the OSM license terms that allows anyone to utilize OSM data for any purpose, including commercial use, and only requiring them to attribute OSM.

For these reasons, an explicit waiver or permission letter from the agency/data owner is required.

What do I need to do to use Philippine government data?

Before using any Philippine government data, you must secure a written consent from authorized signatories of the government agency that owns said data, where they agree to publish them in OpenStreetMap under ODbL.

"Using" includes tracing over the map, copying a name from the map, or pinpointing a coordinate on the map. Prudently, the OSMF tend to regard all of these as a form of copying, or "creating a derived work".

The following government agencies (or their bureas, and sub-offices) publish data with public access (and/or download) but are currently incompatible with OSM license.

• National Mapping and Resource Information Agency (NAMRIA)
• Philippine Statistical Authority (PSA)
• Project NOAH (some data are derived from PSA-owned geodata)
• Department of Public Works and Highways (DPWH)
• Department of Environment and Natural Resources (DENR)

The above list is incomplete, but cites some agencies who publish data and/or maps that are publicly accessible BUT incompatible with ODbL, as it-is. The remedy to this restriction is secure from them a written consent by authorized signatories, and permission to use their data in OSM, under the terms of ODbL that covers all OSM data.

How about data donors from non-governmental organizations?

Private and non-governmental organizations (e.g. orgs who license their data in CC-BY-NC) should follow the same steps as data from the government. The donors are expected to publicly publish their data, with an explicit license compatible with OSM, or additionaly with a specific waiver of rights in favor of OSM.

The following sources publish data for free access (and/or download) but are currently incompatible with OSM license:

• Philippine GIS Data Clearinghouse (PhilGIS)
• Justin Meyers' GitHub repo for the Philippines

How about using Google Maps/whoever data?

That data is copyrighted and owned by many other organizations that Google/whoever just licenses from. If we were to use it, OSMF would have to pay for it.

The Terms of Service of Google Maps/Google Earth Terms of Service disallows you from using their data for creating or augmenting any mapping-related dataset:

When using Google Maps/Earth/Street View, you may not […] use Google Maps/Earth/Street View to create or augment any other mapping-related dataset (including a mapping or navigation dataset, business listings database, mailing list or telemarketing list)..

The OSM project intends to provide a free dataset which will enable everyone -- enthusiasts, citizen scientists, programmers, social activists, practitioners, map makers, YOU -- to use them without any technical or legal restrictions.

What will happen to data that's been added to OSM if they come from incompatible sources?

The OpenStreetMap Foundation and community respects the intellectual property rights of others. The Foundation, and the community will respond to specific claims of copyright infringement provided that sufficient information is given, or can be determined.

After they've been ascertained as incompatible, and possibly co-ordinating with the Data Working Group for planned actions, the data will be removed from OpenStreetMap, while personally identifiable information (PII) may be redacted.

The adopted practice of the OSM-PH community is to secure the necessary permission from the data owners. The Licensing Working Group affirms this conservative stance and recommends the same globally, where applicable.

I have data I want to contribute to OpenStreetMap but I'm not sure how to proceed.

Check out any OSM community channels in the Philippines for advise or assistance.

Some questions to ask yourself:

• If you're not the data owner, what rights do you have over them?
• What kind of pre-processing is required, to make it usable for OpenStreetMap?
• Is the data free of personally identifiable information?
• Is OpenStreetMap the appropriate platform?
  • For aerial imagery, try OpenAerialMap
  • For tabular (or other formats) data, you can host them in public repositories like Github, etcetera.

Even if you think your data license is compatible with OSM, it makes a lot of sense to coordinate with the local community and discuss your plans with them, especially when dealing with large datasets.

We're interested in adding address details of our neighbourhood. Is that okay?

If you collect public address information (housenumber, street name), which are publicly accessible, on your own, they should be alright to add to OpenStreetMap. If you're planning to collect the data electronically, you might want to look at apps similar to KeypadMapper for this purpose.

However, private and personally identifiable details of people (e.g. names (even just surnames), phone numbers, email addresses, family composition, economic status, etc.) has no place in OSM.

You may keep these in your own private databases, and synchronize the data with some key, to tie it to the map (e.g their address)
