Copyrighting Drone Mapping Data and Topographical Models for Solar Sites in the Philippines: Ownership, Commissioned Works, and State Controls

Introduction

Foreign energy developers commonly commission local drone operators, survey teams, and GIS consultants to generate aerial photographs, orthomosaics, and 3D terrain/topographical models for solar site screening, permitting, engineering, and financing. In the Philippines, ownership and exploitation of these outputs requires attention to two separate legal layers: (1) copyright under the Intellectual Property Code, and (2) State regulation and control over aerial photography and mapping materials under security-focused decrees.

This article explains how Philippine law treats copyright ownership of original aerial photos and derivative 3D terrain models that are commissioned by foreign prospectors, and how State control rules can affect possession, deposit, reproduction, and disclosure of the materials.

Governing Laws and Core Concepts

Copyright protection in the Philippines is governed by Republic Act No. 8293 (Intellectual Property Code of the Philippines, 1997). The law protects “works” from the moment of their creation and includes, among others, illustrations, maps, plans, sketches, charts, and three-dimensional works relative to geography or topographyand photographic works (Intellectual Property Code of the Philippines, 1997, Section 172).

Separate from copyright, aerial photography and photomapping are subject to government oversight. Presidential Decree No. 1178 (Management and Regulation of Aerial Photography and Mapping Activities, 1977) centralizes control and supervision of aerial photography and photomapping activities in the Secretary of National Defense, including the processing, handling, distribution, reproduction, and safekeeping of aerial photography and other reproducible mapping materials (PD 1178, 1977, Sections 1 and 2). PD 1178 also declares that negatives and other reproducibles of aerial photographs belong to the State, subject to implementing rules (PD 1178, 1977, Section 4).

Relatedly, Presidential Decree No. 1588 (Establishing a National Cartography, Photogrammetry and Remote-Sensing Center, 1978) establishes a national center intended to consolidate mapping and remote-sensing functions, reinforcing the policy direction toward centralized oversight of mapping-related activities (PD 1588, 1978).

What Outputs from a Solar Site Drone Mapping Project Can Be Copyrighted?

Under the Intellectual Property Code, the following are commonly copyrightable if they meet the requirement of original intellectual creation:

• Original aerial photographs captured by drone operations (photographic works).
• Orthomosaics and photomosaics that reflect original selection, processing, and arrangement (often treated as photographic/graphic works depending on how produced and presented).
• Topographic maps, contours, plans, and site plates (maps, plans, charts).
• 3D terrain models, triangulated meshes, textured models, and similar 3D representations of topography (three-dimensional works relative to geography/topography).

Philippine jurisprudence recognizes that Section 172 of the Intellectual Property Code covers these categories. The Supreme Court has reiterated that works enumerated under Section 172 are protected from the moment of creation (Juan v. Juan, et al., G.R. No. 221732, 2017, citing Section 172).

What Copyright Does Not Automatically Cover: “Expression” vs. “Underlying Object/Information”

Even when mapping outputs are copyrightable, copyright generally protects the author’s expression, not the underlying idea, facts, or functional object being depicted. The Supreme Court’s discussion in Olaño, et al. v. Lim Eng Co (G.R. No. 195835, 2016) is instructive: a copyright over plans or drawings covers the drawings themselves, not necessarily the useful article depicted. Applied to drone mapping, this distinction is important for two recurring scenarios:

• Terrain and coordinates as facts: raw location facts, elevations, and coordinates are not “owned” as facts merely because they appear in a protected map or model.
• Engineering use: the ability to design or build a solar project on a site is not automatically controlled by whoever owns copyright in the site plates or 3D visualizations, though copying the protected plates/models without authorization may still infringe.

Who Owns Copyright in Commissioned Drone Photos and 3D Terrain Models?

As a starting point, ownership depends on authorship: copyright belongs to the person who created the protectable expression. The Supreme Court has emphasized that copyright protects the expression of an idea and that one who merely contributes concepts is not deemed an author of the resulting work (Republic of the Philippines v. Heirs of Tupaz, et al., G.R. No. 197335, 2020).

In commissioned projects, the typical ownership outcomes depend on the contract structure and production reality:

Typical Contracting Structures and Likely Ownership Results

Note: This table describes common outcomes and risks; final ownership should be fixed by written contract terms and supported by clear project documentation.

Scenario	What is usually created	Main copyright risk	Recommended contract outcome
Foreign prospector hires PH drone/GIS vendor as an independent contractor	Aerial photos, orthomosaic, 3D terrain model, maps/plates	Vendor may remain the copyright owner by default if rights are not assigned/licensed clearly	Written assignment or a sufficiently broad license (including reproduction, adaptation, and onward sharing to EPC, lenders, investors)
Foreign prospector uses a prime consultant who subcontracts data capture and modeling	Mixed outputs and layered deliverables	Split rights (drone operator owns photos; modeler owns 3D model; prime owns report compilation)	Flow-down clauses ensuring all upstream rights are assigned/licensed to the prospector or prime, with permitted uses defined
Client provides templates/specs and directs what to capture	Still an authored photo/model	Client direction alone does not make the client the “author”	Express ownership/assignment provisions; define authorship, moral rights handling, and crediting

What to Put in the Commissioning Contract (Ownership and Use Clauses)

To avoid disputes, a foreign energy prospector commissioning Philippine mapping deliverables should typically address the following in writing:

• Work product definition: list specific deliverables (raw photos, processed orthomosaics, DSM/DTM, point clouds, 3D mesh, contours, plates, reports).
• IP allocation: specify whether outputs are assigned to the client upon payment, or licensed (exclusive/non-exclusive), and identify any vendor-retained tools or pre-existing libraries.
• Permitted uses: include feasibility studies, permitting support, financing due diligence, EPC bidding, O&M planning, and disclosure to affiliates and professional advisers under confidentiality.
• Right to modify and create derivatives: important for iterative engineering and reprocessing.
• Warranties and indemnities: vendor warrants original work and non-infringement, including subcontractor outputs.
• Data retention and audit trail: define custody of raw files and logs; ensure reproducibility of processing steps.

State Controls on Aerial Photography and Mapping: Why Copyright Clauses Are Not Enough

Even if the contract grants the foreign prospector ownership or a broad license, PD 1178 imposes a separate layer of State control over aerial photography and photomapping activities. PD 1178 declares a policy of centralized planning of aerial photography and base map production under the Department of National Defense and states that negatives and other reproducibles of aerial photography are considered property of the State, subject to rules prescribed by the Secretary of National Defense (PD 1178, 1977, Section 1). It also provides that the Secretary of National Defense exercises control over handling, distribution, reproduction, safekeeping, and final disposition of aerial photography and other reproducible mapping materials (PD 1178, 1977, Section 2).

For foreign prospectors, the practical effect is that certain aerial imagery or mapping materials may be subject to clearance, deposit, classification rules, or restrictions on reproduction and dissemination, depending on the implementing rules and the nature/location of the imagery.

Handling Classified or Sensitive Mapping Materials

PD 1178 provides that negatives and reproducibles of classified aerial photographs shall be deposited with the Armed Forces of the Philippines, and when declassified they shall be deposited with the Bureau of Coast and Geodetic Survey, with copies made available under the conditions stated in the decree (PD 1178, 1977, Section 4).

For a solar site project, this becomes relevant when the area overlaps with locations that may raise security sensitivity. Contract drafting should anticipate that:

• Some deliverables may be subject to government deposit/custody rules.
• Exporting or sharing imagery outside the Philippines (e.g., to the foreign head office or overseas funders) may require confirmation of compliance with applicable clearances and restrictions.
• The vendor’s compliance obligations (permits/clearances) should be explicit, with documentary proof to be provided to the client.

Examples and Common Scenarios

Scenario 1: Investor due diligence pack. A foreign developer commissions drone mapping, then shares the 3D terrain model with an overseas investor. If the vendor retained copyright, the sharing could breach the license. Separately, if a clearance regime applies to the imagery/model, sharing may also raise compliance issues under PD 1178’s control principles (PD 1178, 1977, Sections 1–2).

Scenario 2: EPC tender and redesign. The developer provides orthomosaic and contours to multiple EPC bidders. Without an explicit right to reproduce and distribute to third parties, the tender circulation may exceed the vendor’s permitted scope. Contract language should expressly permit this use and authorize derivative works (e.g., updated grading plans based on the terrain model).

Scenario 3: Competing site screening. A vendor reuses the same aerial photos or models for another client. If the commissioning contract intended exclusivity, the contract should clearly prohibit reuse and require deletion/return of specified files, subject to any lawful retention or government deposit obligations.

Risk Management Checklist for Foreign Energy Prospectors

• Confirm copyright chain-of-title: ensure all subcontractors assign rights to the prime, then to the client (or license accordingly).
• Specify allowed disclosures: affiliates, lenders, investors, advisers, EPC bidders; include confidentiality controls.
• Address raw vs. processed outputs: define whether the client receives raw photos/point clouds and the right to reprocess.
• Compliance documentation: require the vendor to document compliance with applicable aerial photography/mapping controls (PD 1178, 1977, Sections 1–2).
• Plan for government custody/classification contingencies: define what happens if materials are classified or must be deposited (PD 1178, 1977, Section 4).

Conclusion

In Philippine law, original drone aerial photos, mapping outputs, and 3D terrain models for solar sites are generally protectable as copyrightable works under the Intellectual Property Code (RA 8293, 1997, Section 172). However, copyright protects expression rather than underlying facts or functional outcomes, and disputes often arise when commissioning contracts do not clearly allocate ownership and permitted uses, as reflected in Supreme Court guidance distinguishing protected expression from the underlying object depicted (Olaño, et al. v. Lim Eng Co, G.R. No. 195835, 2016) and requiring actual authorship rather than mere conceptual contribution (Republic v. Heirs of Tupaz, G.R. No. 197335, 2020).

For foreign energy prospectors, it is equally important to account for State oversight of aerial photography and mapping materials under PD 1178 (1977), including control over handling and reproduction and the State’s asserted ownership over negatives and reproducibles. The recommended approach is a well-defined IP clause set (assignment or broad license), supported by chain-of-title, and paired with compliance representations and evidence addressing aerial photography/mapping controls.
