Types of aerial photographs
- Aerial photographs are images taken from the air, providing a bird's-eye view of large areas.
- Orthophoto maps are aerial photographs or satellite images corrected for topographic relief, lens distortion, and camera tilt, ensuring uniform scale.
- Orthophotos combine photographic image characteristics with map geometric qualities.
- Satellite images are digital images from sensors on orbiting satellites.
- Sensors collect data in various wavelengths of the electromagnetic spectrum, processed into images highlighting different aspects of Earth's surface.
Categories of Aerial Photographs
- Oblique Aerial Photograph: Camera angled between horizontal and vertical, capturing object sides for easier identification.
- Low Oblique Aerial Photograph: Camera tilted ~30° from vertical, showing only the ground surface without the horizon.
- High Oblique Aerial Photograph: Camera tilted ~60° from vertical, showing both the ground surface and the horizon.
- Vertical Aerial Photograph: Camera axis nearly perpendicular (90°) to the ground.
- Positioning ensures accurate spatial relationships between features, though top views may make some features harder to recognize.
- Horizontal Photograph: Taken with the camera pointed directly horizontally, used for photographing landscapes, objects, or people from the air, but not typically classified under aerial photographs used for mapping.
Integration with GIS
- Georeferencing involves aligning images with geographical locations using GPS and surveying techniques.

- Rotate the compass casing to align the 'North' on the compass card with the needle pointing north.
- Compasses display cardinal points (North, South, East, West) and often intermediate directions, totaling up to 16 points on detailed compasses.
- Alignment of the compass with true north on a map is crucial for accurate direction finding.
- Directions to other features or places are described using the compass points from a chosen point of reference.
Describing Position with Coordinates
- Coordinates are given as intersections of lines of latitude and longitude.
- Every location on Earth can be precisely described using coordinates.
- The network of latitude and longitude lines forms a geographical grid around the Earth which is known as a graticule.
- This aids in the accurate pinpointing of locations.
Map Projections
- Map projections are methods used to represent the curved surface of the earth on a flat map.
- Because the Earth is spherical, lines of latitude and longitude appear as squares near the equator and become more triangular near the poles when flattened onto a map.
Conservation in Map Projections
- Shape: To maintain the true shape of regions as much as possible.
- Area: To ensure regions are represented in true proportion to their actual size.
- Direction: To accurately depict the directions between locations.
- Distance: To represent the true distances between locations accurately.
Types of Map Projections
- Mercator Projection (1569): Useful for navigation, accurately showing angles and directions but distorting shapes and distances, especially near the poles.
- Robinson Projection (1961): Represents the global shape more realistically, conserving the relative shapes of landmasses but distorting direction and distance.
- Peters Projection (1972): An equal-area projection that shows the true sizes of land masses but distorts their shapes, often seen as favoring developing nations.
Measuring Bearings
- Bearing: The measurement of direction of one location from another.
- Expressed in degrees.
- Used for navigation and orientation on a map.
- Magnetic North: The direction to which a compass needle points, continuously shifting slightly.
- True North: The direction along the Earth's surface towards the geographic North Pole.
- Magnetic Declination: The angle between magnetic north and true north.
- Changes in declination are noted on maps to assist with precise orientation.
Steps to Measure an Angle with a Compass
- Identify the reference point (FROM) and the target point (TO).
- Draw a line representing true north from the reference point.
- Measure the angle from the true north line to the line joining the reference and target points.
Identifying Landforms
- Contours on a map are lines that connect points of equal elevation.
- Closely Spaced Contours: Indicate steep slopes.
- Widely Spaced Contours: Indicate gentle slopes.
- Convex and Concave Slopes: Revealed by the patterns of contour lines.
Contours
- Provide information about the relief and landforms of an area.
- Influence where people might live, farm, or build infrastructure.
Measuring Distance
- Map scales indicate the relationship between distances on the map and actual distances on the ground.
- Ratio/Number Scales: For example, a scale of 1:50,000 means 1 cm on the map represents 50,000 cm (500 meters) on the ground.
- Line Scales: Allow for direct reading of distances on the map without calculations.
Calculating Distances
- Measure the distance on the map in centimeters.
- Multiply by the scale factor to find the actual distance.
- Convert to appropriate units (meters or kilometers).
Conducting Fieldwork
- Fieldwork involves direct data collection in the natural environment.
- Steps are organized by the mnemonic "FIELDWORK"
"FIELDWORK"
- F: Finding a Topic: Choose a current, relevant, and interesting issue.
- Identification of Topic: Affecting the local community or environment.
- This can be accomplished through brainstorming, discussions, or reviewing local media.
- I: Information Gathering
- Preliminary Research: Determine the necessary background information.
- Understand the scope of the topic before beginning the actual fieldwork.
- E: Engaging with Stakeholders/Local Environment
- Identify Information Sources: Decide who will provide the needed information Engaging with local stakeholders is crucial.
- Methods of Engagement: Use surveys, questionnaires, or observational templates to collect data from the community.
- L: Localizing Your Investigation/Fieldwork
- Planning and Community Engagement: Plan the fieldwork to align with the local context and actively engage with the community.
- Safety Measures: Ensure all safety protocols are in place during the fieldwork.
- D: Data Gathering
- Type of Data: Decide whether the data to be collected is quantitative or qualitative (such as perspectives or opinions).
- Involving measurements such as counting or averaging
- Tools for Data Collection: Use appropriate tools like tape recorders, thermometers, or cameras to gather reliable and valid data.
- W: Working Effectively
- Time Management and Planning: Organize the timeline and manage different phases of the fieldwork efficiently,
- Role Allocation in Teams: If working in a group, ensure roles and responsibilities are clearly assigned and deadlines set.
- O: Organizing Your Data
- Data Analysis: Classify the collected data into categories such as fact, opinion, consensus, and notable contrasts.
- Theme Development: Organize the data around key themes and subthemes.
- R: Recording and Reporting Your Findings
- Documentation: Record findings according to the identified themes and subthemes.
- Report Writing: Prepare a concise report in an accepted format, ensuring it reflects the objective evaluation of the data.
