Documentation used to be an afterthought in street advertising. The campaign ran, the operator took some photos on a phone, and a folder of JPEGs arrived by email a few days later. That approach worked in markets where everyone involved knew each other, the scale was small, and the client trusted the operator completely.
International wheatpaste campaigns don’t have those conditions. The client is in New York or London. The operator is in Tokyo, Berlin, or São Paulo. Nobody knows each other yet. The campaign spans multiple cities, multiple time zones, and potentially multiple operators reporting into a single brief. In that environment, documentation is not an afterthought — it’s the chain of evidence that connects the placement on the wall to the budget line on the media plan.
American Guerrilla Marketing has run wheatpaste campaigns in international markets for over a decade. GPS-tagged documentation is standard on every campaign we run, domestic and international. This piece explains what that documentation actually contains, how brands use it, where documentation processes break down, and how to build proper requirements into your campaign brief before a single sheet goes up.
The term “GPS documentation” gets used loosely. When AGM uses it, we mean a specific set of data points for each placement:
A documentation report assembles all of these data points across every placement in the campaign into a single deliverable. In a well-structured report, each placement has a unique identifier that links the coordinates, the photo, and the specification data. A client reviewing the report can pull up any placement, see exactly where it is on a map, and see the photo of what was installed there.
A domestic campaign in a single city between a brand team in New York and an operator also in New York has built-in accountability mechanisms: the brand team can drive by the walls, they know the streets, they have informal verification channels. If documentation is incomplete, they can fill in the gaps with local knowledge.
International campaigns have none of those backup mechanisms. If your campaign is running in Seoul, Sydney, and Amsterdam, your marketing team cannot verify placements in person. The documentation is the only record of what happened. If it’s inadequate, incomplete, or delayed, you have no way to confirm that your campaign ran as specified.
This creates several problems that are specific to international work:
A campaign installed in Tokyo at 11 p.m. local time on a Tuesday is being installed at 9 a.m. Tuesday morning in New York. When the New York team arrives at the office Wednesday morning, the documentation should already be in their inbox. It won’t be if the Tokyo operator sends documentation at the end of their workday on Wednesday — which would be Wednesday night New York time.
The solution is building documentation delivery windows into the campaign brief with explicit reference to time zones. “Documentation delivered within 24 hours of installation, by 9 a.m. Eastern time” is a clear standard. “Documentation delivered promptly after installation” is not. The ambiguity of the second version is where delays and disputes grow.
A campaign running in six cities across three continents will generate documentation from six different operators, in potentially six different formats, in three or more languages, at six different local times. If each operator sends documentation independently to the client, the client receives six separate reports that may be structured differently, use different coordinate formats, and include photos at different resolution and quality standards.
What the client actually needs is a single consolidated report that presents all six markets in a consistent format, with a summary table showing total placements by city and links to the photo documentation for each. That kind of report requires a campaign coordinator — typically the lead agency — to receive all six operator reports and consolidate them before client delivery. AGM handles this consolidation as a standard part of multi-market international campaigns. It’s not a feature; it’s how international campaigns should work.
Coordinate formats, date notation, and measurement units differ by market. A documentation report from a Japanese operator may express coordinates in degrees, minutes, and seconds (DMS format) rather than decimal degrees. A European report may use day-month-year date notation rather than month-day-year. A UK report may express dimensions in millimeters rather than inches.
None of these are errors — they’re national conventions. But they create friction for a US brand team reviewing documentation in an unfamiliar format. A properly structured multi-market report standardizes all of these conventions to a single format before client delivery.
GPS documentation isn’t just proof that placements happened. It flows into multiple internal functions within a brand or agency organization:
Finance and procurement teams at major brands require documentation of media spend execution. A wheatpaste campaign entry in a media plan needs the same verification of execution as a digital display campaign or an out-of-home buy. GPS-tagged documentation provides the physical evidence that corresponds to the billing entry. Without it, the media accounting entry is an unsupported claim.
Marketing teams report campaign activity to leadership. “We ran a 15-city international wheatpaste campaign” is a much more defensible statement when supported by a documentation report showing GPS coordinates and photos for every placement than when it’s supported by an invoice and a folder of phone photos. Documentation gives marketers the evidence they need to report campaign execution with confidence.
For brands working with agencies, GPS documentation provides the verification layer that supports agency billing. The agency invoices for placements in specific locations. The documentation confirms that those placements occurred at those locations on those dates. Without documentation, the billing is on an honor system. With it, the billing is verifiable.
High-quality context photos from international campaigns often find second life in marketing materials. A photo of your brand on a wall in Tokyo or Berlin, captured in a compelling urban context, is genuinely useful creative content. Documentation photos serve double duty — verification and asset library — when they’re shot with that in mind.
Documentation expectations vary by market, and the variation is worth understanding before you write your brief:
US brand teams have the highest documentation expectations of any market. Same-day delivery is the standard expectation. Photo quality requirements are high. Coordinate precision expectations are high. US clients often want documentation before the campaign’s creative director has seen the photos — verification comes first, approval of the creative execution follows.
UK, German, French, and Dutch operators generally have strong documentation practices. Same-day delivery is achievable in most cases, and photo quality is reliable. GDPR considerations in some European markets affect what can be photographed in public spaces — documentation photos that clearly show identifiable individuals may need to be edited before client delivery. This is a production consideration rather than a dealbreaker, but it needs to be planned for.
Japanese operators are generally among the most precise for documentation — coordinate data is accurate, timestamps are reliable, and photos are well-framed. The time zone difference from the US East Coast (14 hours ahead) means that same-day US delivery requires the Japanese operator to submit documentation within hours of installation. Build this into your brief explicitly.
Documentation quality in Latin America varies more than in other regions, partly because the street advertising industry has developed at different rates across countries. Cities with established advertising markets — Mexico City, São Paulo, Buenos Aires, Bogotá — have operators with professional documentation practices. Secondary cities may require more explicit brief requirements to ensure documentation meets brand standards.
Singapore has Western-standard documentation practices. Indonesia, Thailand, Vietnam, and the Philippines have developed markets with capable operators, but documentation standards vary by operator rather than by country. AGM works with verified operator partners in Southeast Asia whose documentation practices have been tested on previous campaigns.
Documentation failures fall into three categories: missing, late, and insufficient.
The most serious failure. Documentation that never arrives means there is no record of whether placements occurred. The causes range from operator failure (never took photos) to logistical breakdown (photos taken but not submitted to the coordinator) to technical failure (photos deleted or lost). Missing documentation for any placement should trigger immediate follow-up — not an assumption that the placement happened.
Late documentation disrupts internal timelines. Marketing teams with weekly or daily reporting cycles need documentation on time to include campaign activity in their reports. Finance teams with month-end cutoffs need documentation before they can book the expense. A campaign that ran in late February but delivered documentation in mid-March creates accounting complications that are avoidable with a clear brief and a defined delivery deadline.
Technically complete but practically useless. Photos that show a poster but not enough context to identify the location. Coordinate data that’s accurate to two decimal places rather than five, placing the documented location within a quarter-mile radius rather than on a specific wall. Timestamps in local time without a time zone identifier. Photos so low in resolution that the brand can’t use them for any secondary purpose. Insufficient documentation technically fulfills a documentation requirement while failing to serve any of the functions documentation is supposed to serve.
The most reliable way to get documentation that meets your needs is to specify it explicitly before the campaign begins. Vague requirements produce variable results. Specific requirements produce consistent results.
A documentation section in a campaign brief should specify:
Most smartphones automatically embed GPS coordinates into photos when location services are enabled. This means that any photo taken by a phone with location services on has GPS data in its EXIF metadata. In theory, that’s GPS documentation.
In practice, there are meaningful differences between phone-camera GPS documentation and documentation produced through professional GPS-logging software:
| Factor | Phone Camera GPS | Professional Documentation Software |
|---|---|---|
| Coordinate precision | Variable — affected by urban canyons, weak signal | Higher precision, often with satellite count logged |
| Timestamp standardization | Local device time — may not match actual local time if device clock is wrong | Server-synchronized time, time zone explicit |
| Report aggregation | Manual — someone has to compile photos into a report | Automatic — software generates report from logged placements |
| Tamper evidence | None — photos can be edited | Some platforms provide hash verification |
| Multi-operator consistency | Each operator using different phones, settings, apps | Standardized platform across all operators |
For small domestic campaigns with a single trusted operator, phone-camera GPS is adequate. For international multi-city campaigns where documentation needs to withstand internal audit or billing dispute scrutiny, professional documentation software eliminates the inconsistencies that create problems later.
When American Guerrilla Marketing runs a multi-city international campaign, documentation flows through a single reporting structure rather than as separate reports from each market operator.
Here’s the process: each operator logs placements in real time using a standardized GPS documentation system. Coordinates, timestamps, and photos are submitted through that system as installations are completed. The AGM campaign coordinator monitors submissions in real time and follows up on any gaps immediately — during the installation window, not days later.
Within the specified delivery timeline (typically 24 hours of installation for international markets), the campaign coordinator compiles a consolidated report that presents all markets in a consistent format. The report includes a summary table showing totals by city, a map view of all placements with clickable coordinate links, and a gallery of context photos organized by market.
The client receives one report that covers all markets. They don’t need to reconcile reports from six different operators. They don’t need to translate documentation from three different languages. They open one file and see their entire campaign.
A client should be able to do three things with a properly structured documentation report:
A report that passes these three tests doesn’t require any follow-up from the agency. The client has everything they need. That’s the standard we hold ourselves to at AGM, and it’s the standard we’d recommend writing into any international wheatpaste campaign brief.
| Failure | Cause | Prevention |
|---|---|---|
| Photos without location context | Operator didn’t understand requirement | Specify context visibility requirement in brief |
| Documentation delivered days late | No specified delivery deadline | Define delivery timeline with time zone in brief |
| Missing placements in report | Operator skipped documentation for some sites | Require real-time submission through logging system; coordinator monitors during installation |
| Inconsistent formats across markets | No standardization requirement | Specify coordinate format, date format, language, measurement units in brief |
| Low-resolution photos | Operator used low-quality settings | Specify minimum resolution in brief |
| Multiple separate reports instead of consolidated | No consolidation requirement specified | Specify single consolidated report format in brief |
| No escalation when documentation gaps appear | No escalation protocol defined | Define escalation protocol: operator notifies coordinator immediately; coordinator notifies client within 4 hours |

A complete GPS documentation report includes exact coordinates for each placement, a timestamp, a photo of the placement in context (showing the poster on the wall with surrounding environment visible), surface description, format dimensions, and quantity count. Professional GPS-tagged documentation software embeds coordinates directly into the image file metadata rather than relying on the photographer to manually log a location. AGM provides this standard documentation on every campaign we run.
US brands typically expect same-day documentation delivery — a report submitted the night of or morning after installation. For international campaigns, time zone differences can mean documentation arrives the next morning. A well-structured international campaign brief specifies the delivery window explicitly: same-day where possible, next-morning-local-time where time zones make same-day impractical. The key is that the standard is defined in the brief, not assumed.
A standard phone camera embeds GPS coordinates from the device’s location services into the image EXIF data — if location services are enabled. Professional GPS documentation software does this with higher precision, adds timestamps in a standardized format, and typically includes a reporting interface that aggregates multiple placements into a single viewable report. Phone-camera GPS is adequate for small domestic campaigns; for international multi-city work, professional software produces documentation that can survive internal audit and billing dispute scrutiny.
Missing documentation creates three problems: the client cannot verify that placements occurred, the agency cannot justify its billing, and any internal reporting is based on a claim rather than evidence. In practice, incomplete documentation is one of the most common sources of client-agency disputes in street advertising campaigns. The solution is preventing the problem at the brief stage — not managing it after it occurs.
Yes. GPS-tagged proof-of-posting documentation is standard on all American Guerrilla Marketing campaigns, domestic and international. For multi-market international campaigns, we deliver documentation through a single reporting interface so clients receive one consolidated report rather than market-by-market files from different operators. Documentation delivery timelines are specified in the campaign brief before installation begins — there are no surprises at the delivery stage.
