Part I -- Planning Fieldwork

Sampling Strategies

No fieldworker can observe everything. Sampling determines which locations, times, and phenomena are measured.

Safety and Ethics

Physical safety: File trip plans. Carry communication equipment. Know the terrain, weather, and hazards (tides, wildlife, unstable slopes, temperature extremes). Work in pairs or teams. Carry first aid supplies.

Ethical fieldwork: In human geography, informed consent is required for interviews and surveys. Respect community boundaries, cultural protocols, and privacy. In physical geography, minimize site disturbance -- the fieldworker's footprint should be as light as possible. In Indigenous territories, research must be conducted in partnership with, not merely about, the community.

Part II -- Physical Geography Field Methods

Landscape Observation

Reading a landscape is a core geographic skill. Stand at a viewpoint and systematically observe:

1. Geology: What rock types are visible? What is the underlying structure (horizontal beds, folded strata, igneous intrusion)?
2. Geomorphology: What landforms are present? What processes created them (fluvial, glacial, aeolian, tectonic)?
3. Hydrology: Where does water flow? Are there visible channels, springs, wetlands, evidence of flooding?
4. Vegetation: What plant communities are present? How do they correlate with slope, aspect, elevation, soil?
5. Human imprint: What land uses, structures, and modifications are visible? How have people shaped this landscape?
6. Temporal clues: What evidence of change is visible (terraces, old channels, abandoned fields, successional vegetation)?

Record observations with sketches, photographs (with scale reference), and written notes including grid reference, date, time, weather, and observer.

Transects and Quadrats

Transects: A line (or belt) across a landscape along which measurements are taken at regular intervals. Used to measure changes across a gradient (elevation, distance from river, slope position).

• Line transect: Record what the line crosses (plant species, soil type, land cover).
• Belt transect: Record everything within a strip of defined width along the line.
• Interrupted belt: Sample quadrats at regular intervals along the transect line.

Quadrats: A defined area (often 0.5m x 0.5m for vegetation, 1m x 1m for rocky shores) within which all individuals or features are counted. Multiple quadrats provide density, frequency, and percentage cover data. The number and size of quadrats depend on organism size and spatial variability.

Environmental Monitoring

Stream discharge measurement:

1. Select a straight, uniform reach.
2. Measure cross-sectional area (width x depth at intervals).
3. Measure flow velocity at 0.6 x depth at each interval (float method, flow meter, or current meter).
4. Discharge (Q) = sum of (area x velocity) for each subsection. Units: m^3/s or cumecs.

Soil sampling:

• Auger or soil pit to expose the profile.
• Record horizon boundaries, color (Munsell chart), texture (sand/silt/clay by feel), structure, and moisture.
• Collect samples for laboratory analysis (pH, organic matter, nutrients, particle size distribution).

Weather station data: Temperature (max, min, wet-bulb, dry-bulb), precipitation (rain gauge), wind speed and direction (anemometer, wind vane), humidity (psychrometer or hygrometer), atmospheric pressure (barometer), solar radiation (pyranometer).

Part III -- Human Geography Field Methods

Surveys and Questionnaires

Design principles:

• Define the population and sampling method (random, stratified, convenience).
• Keep questions clear, unambiguous, and culturally appropriate.
• Mix closed questions (Likert scales, multiple choice) for quantitative analysis with open questions for qualitative depth.
• Pilot test before full deployment.
• Record location (GPS) for spatial analysis of responses.

Spatial surveys: Map-based questionnaires where respondents mark locations (home, workplace, service access, perceived boundaries, mental maps). Useful for understanding spatial behavior and perception.

Interviews and Oral History

Semi-structured interviews: A topic guide with key questions but flexibility to follow the respondent's narrative. Essential for understanding local knowledge, perceptions, and lived experience of place.

Walking interviews: Researcher and participant walk through a landscape together, with the landscape prompting discussion. Particularly effective for exploring sense of place, memory, and spatial practice.

Oral history: Recorded accounts of past events, practices, and landscapes from community members. Valuable for documenting landscape change, historical land use, and Indigenous geographic knowledge.

Observational Methods

Participant observation: The researcher spends extended time in a community, participating in daily activities while recording observations. Standard in ethnographic geography.

Systematic observation: Counting, timing, or categorizing activities at a site. Pedestrian counts, traffic surveys, land use mapping, behavior mapping. Structured data sheets ensure consistency.

Photography and sketching: Visual documentation of landscapes, building types, street scenes, signage, and spatial practices. Field sketches force the observer to decide what matters -- the act of drawing sharpens observation.

Part IV -- GPS and Field Mapping

GPS in Fieldwork

How GPS works: Trilateration from 4+ satellites provides latitude, longitude, and elevation. Standard accuracy: 3--5 meters with civilian receivers. DGPS (Differential GPS) or RTK (Real-Time Kinematic) achieves centimeter-level accuracy.

Field GPS tasks:

• Waypoint collection: Record locations of sample sites, features, boundaries, interview locations.
• Track logging: Record a continuous path walked or driven. Useful for mapping trails, boundaries, and transect routes.
• Navigation: Navigate to pre-defined sample sites using uploaded coordinates.

Data integration: GPS points and tracks export as GPX files, importable into GIS software for overlay with satellite imagery, topographic maps, and other spatial datasets.

Field Mapping

Geomorphological mapping: Symbols and colors denote landform types, processes, and materials on a base map. Standardized legend systems (British Geomorphological Research Group conventions) ensure consistency.

Land use / land cover mapping: Walk or drive the study area, delineating land use boundaries on a printed satellite image or base map. Classify parcels using a defined scheme (Anderson Level I/II, CORINE, or custom). Ground-truth a sample of remote-sensing-classified pixels.

Part V -- Data Recording and Integration

The Field Notebook

The field notebook is the primary record. It should be:

• Waterproof (Rite-in-the-Rain or similar).
• Dated and located on every page (date, grid reference, weather).
• Systematic: Standardized data recording format for each method.
• Reflective: Include observations, questions, hypotheses, and sketches alongside quantitative data.
• Backed up at the end of each day (photograph pages, transfer digital data).

Field-to-GIS Pipeline

1. Collect field data with GPS and structured recording forms.
2. Transfer GPS data to GIS (GPX import).
3. Enter attribute data into a geodatabase linked to spatial features.
4. Overlay field data with existing spatial datasets (satellite imagery, DEMs, census boundaries).
5. Perform spatial analysis (interpolation, overlay, buffer, statistics).
6. Validate GIS outputs against field observations. Return to the field if discrepancies arise.
