Topography Quiz: Test Your Knowledge of Topographic Maps

Study Notes

Topography and Maps

Topography encompasses all identifiable surface features, natural or artificial, with positions relative to elevation above or below a reference datum.
Topographic maps use symbols to depict hills, valleys, streams, and human-made structures.

Topographic Maps

Topographic maps aid in engineering design, resource development, and military planning.
Government agencies, such as the Bureau of Lands and Ministry of Natural Resources in the Philippines, create topographic maps to meet specific needs.

Thematic Maps

Thematic maps focus on a specific theme or subject, typically overlaid on a skeletal topographic background.
They present data, often statistical, in map form rather than graph form, emphasizing topics like geology, population, crop production, land use, or meteorological data.
Thematic maps vary widely in scale and are not restricted by it, though they are typically medium to small in scale.
They prioritize data classification and representation through abstract symbolism.

Computer-generated Maps

Electronic computers have revolutionized map-making, replacing manual drafting with faster and more varied production methods.
They process digital cartographic information, including survey data, scale, and contour intervals, to generate maps automatically.
Interactive drafting systems enable operators to visualize and modify maps in real-time for accuracy and completeness before printing the final product.
Advantages of computer-generated maps include:
- Faster and more accurate cartographic tasks
- Electronically stored data for convenience and easy retrieval
- Flexibility in resizing maps
- Minimized errors and mistakes

Maps and their Classification

The word "map" originates from the Latin "mappa," meaning napkin or sheet.
Maps can be classified into:
- Planimetric maps
- Topographic maps
- Thematic maps
- Computer-generated maps
- Photomaps

Planimetric Maps

Planimetric maps represent the Earth's surface in two horizontal dimensions without showing elevations.
They accurately depict the horizontal positions of natural and man-made features like buildings, roads, water bodies, and political boundaries.
Planimetric maps are helpful for:
- Locating places
- Measuring distances
- Finding directions
