Choosing a Service Format That Actually Fits

When you work with geological data — field surveys, core logs, or contour maps — the format of the final report or dataset matters more than most people assume. A PDF with high-resolution stratigraphic columns might look professional, but if the field team needs to consult it on a tablet during a coastal walk, a lightweight web map or a GeoPDF works better. The choice is not about quality; it is about how the information will actually be used.

Over the past year, we have prepared several technical summaries for environmental technicians working in the lower Tagus basin. In one case, a client requested a printed A3 booklet with fold-out cross-sections. In another, the same type of data was delivered as a set of KMZ files with embedded borehole logs. Both formats were correct for their respective contexts. The mistake would have been to assume one fits all.

The tradeoffs are straightforward: printed materials are stable, do not depend on batteries, and can be annotated in the field. Digital formats allow layering, zooming, and real-time coordinate reading. The decision depends on the terrain, the duration of the fieldwork, and the technical comfort of the user. For a group of hikers following a trail along the Sintra cliffs, a folded paper map with marked viewpoints is more practical than a GIS project file. For a geologist correlating units across ten boreholes, a spreadsheet with depth tables and a vector profile is indispensable.

We have also found that mixing formats — a short printed guide plus a digital appendix — often works better than committing to a single medium. The guide covers the essential observations and safety notes; the digital part holds the full dataset. This hybrid approach reduces the risk of information overload while keeping the complete record accessible.

The key is to ask, before preparing anything: who will use this, where, and under what conditions? The answer defines the format. Not the other way around.
