3 Survey Records and Documentation

Why survey records matter

Reliable archaeological survey depends on records that connect each observation to its location, method, and context. Good documentation lets later researchers assess what was observed, how it was recorded, and where evidence was—or was not—found. Records should be consistent, complete enough for independent interpretation, and proportionate to the survey’s aims.

Set up and complete observation records

Establish a recording system before fieldwork. It should define standard forms or database fields, unique identifiers, shared terminology, file-naming rules, and procedures for maps, photographs, finds, and digital data. Keep a project record of the methods used and any changes made in the field. Standardized formats make records easier to compare and archive.

For each survey observation, record:

• Who and when: the observer, date, and, where useful, time.

• What was observed: a neutral description of the feature, material, or surface condition, separating direct observation from interpretation.

• Where: the site or project identifier, coordinates, coordinate reference system and datum, and a map or plan reference.

• How: the survey method, coverage, instruments, and relevant settings or procedures.

• Conditions and limitations: visibility, ground cover, access restrictions, weather, disturbance, and other factors that could affect detection.

• Related records: identifiers for photographs, plans, samples, or finds.

Also record Negative evidence. Identify the areas examined and the conditions and methods under which no archaeological evidence was observed. An entry stating only “nothing found” cannot be interpreted reliably without coverage and visibility information. Survey reports should describe the area, methods, coverage, recorded properties, and factors that may have affected results.

Document finds, locations, and photographs

Give each collected or observed find a unique identifier and link it to its survey unit, site, or precisely recorded findspot. Record the material or object category, quantity, collection status, date, recorder, and any relevant condition or identification notes. Use agreed terminology consistently; if identification is uncertain, record that uncertainty rather than presenting a guess as fact. Project instructions and applicable permits determine whether finds are collected, left in place, or recorded without removal.

Location records should state the Coordinate reference system and datum, not just a pair of numbers. Note the equipment or method, estimated precision or accuracy when available, and any processing or coordinate transformation. For a local grid, document its origin, orientation, units, and relationship to a recognized coordinate system. Record survey coverage and the strategy used—such as transects, a fixed grid, or instrument-surveyed points—so another researcher can understand how locations were produced.

Give photographs identifiers linked to the relevant field record. Record their date, subject, direction of view, and scale where appropriate. A photo log and retained image metadata help preserve the connection between images and records.

Distinguish survey and site boundaries

Distinguish the Survey-area boundary, which marks where work was conducted, from the Site boundary, which represents the interpreted extent of archaeological evidence. Map them separately and identify the evidence and criteria used to draw each. A site boundary is an interpretation, not necessarily a visible wall or a precisely known edge.

Where evidence is sparse, obscured, inaccessible, or uncertain, record that limitation and represent the boundary as provisional rather than implying unsupported precision. Store boundaries in a documented spatial format and connect mapped features to descriptive records through stable identifiers. Preserve original field observations as well as later edited or interpreted boundaries, noting who changed them, when, and why, so they can be reassessed.

Check and preserve survey data

Check data quality in the field. Confirm that identifiers are unique, required fields are filled, coordinates use the stated system, and photographs, finds, plans, and notes cross-reference one another. Use Controlled terms for recurring categories, while allowing descriptions that do not fit a preset list. Mark missing information as unknown or not recorded rather than leaving it ambiguous.

At the end of each field session, review records for omissions, duplicated numbers, inconsistent names, and coordinate or file-transfer problems. Keep unaltered originals and document corrections instead of overwriting the evidence trail. Preserve field notes, forms, spatial data, photographs, and the recording manual together, with metadata explaining methods, coverage, precision, and file relationships. Clear documentation of survey strategy and sampling is essential for assessing results and enabling reuse.

Sensitive location information may require restricted access. Follow applicable law, landowner or community agreements, and project requirements when storing, sharing, or publishing site coordinates.

Example and practical outcome

A concise Field record for a surface observation might read: “Unit T04; 14 May; observer AB; moderate visibility, grass cover about 40%; three ceramic fragments observed, not collected; point recorded with handheld GPS in [coordinate system and datum]; estimated precision noted in device log; photograph P018 looking north; location lies near the provisional eastern edge of the observed scatter.”

The entry separates what was seen from the interpretation, links related evidence, and records conditions that affect how the observation should be evaluated. Together, consistent identifiers, documented coverage and visibility, stated coordinate systems and methods, recorded uncertainty, and preserved originals and metadata make survey results understandable, verifiable, and useful to future researchers.
