DASAR DASAR PEMETAAN "PENGERTIAN DAN JENIS - JENIS PETA" PART 1

Main ideas and concepts

• Maps as a foundation of civilization

  • Maps have existed for hundreds of years before Christ; early world maps are associated with Babylon (noted as existing since ~600 years before Christ).
  • Humans used maps to explore and sail.
  • Maps developed and expanded because they provide many benefits across different fields, especially geography.

• Why maps matter in geography

  • In geography education, maps are described as the main feature.
  • Results of geographical studies are displayed in the form of a grid.
  • Maps help support geographical studies/planning and decision-making.

• Field of study and key terms

  • The science that studies maps is cartography.
  • People who are map experts are called cartographers.

Definition of a map (as presented)

A map is described as a depiction of earth-related information using:

• a projection system
• a specific scale
• shown on a flat plane

Different sources/definitions mentioned:

1. General definition (course/chapter context)

   • The appearance of the earth’s surface depicted using a projection system with a certain scale, presented on a flat plane.

2. Government regulation (Regulation No. 8 of 2013)

   • A map is a depiction of natural and/or man-made elements located above or below the earth’s surface, depicted on a flat plane with a certain scale.

3. Geospatial Information Agency (BIGTA / likely BIG)

   • A map is a vehicle for storing and presenting environmental condition data, functioning as a source of information for users (e.g., planners/decision makers).

4. International Geographic Association

   • A map is a perception/depicition of abstract elements related to earth’s surface or celestial bodies, generally shown on a flat plane, and classified based on scale.

Atlas, globe, image, and plan (differences)

• Map: A depiction of the earth’s surface on a flat plane.
• Atlas: A collection of images of the earth’s surface.
• Globe: A three-dimensional representation of the earth as a ball.
• Satellite imagery: A visual capture of the earth’s surface from the air or satellite.
• Plan: A two-dimensional image that usually shows the location of a building, a small space, or a small area.

Methodology / classification of maps (detailed)

1) Classification by content

• General maps

  • Depict all features on the earth’s surface (broad coverage).

• Thematic maps

  • Depict the earth’s surface with a specific theme, depending on mapping purpose.
  • Show quantitative and qualitative data for that theme.
  • Examples given:
    • Transportation route map
    • Geological map
    • Settlement map
    • “Kumu” and similar thematic categories (as mentioned in the subtitles)

2) Classification by scale (five types)

1. Cadastral maps

   • Scale: 1:1000 to 1:5000 (subtitles contain an unclear range but indicate “1 to 100 to 1 Bing 5000”)
   • Characteristics: very detailed
   • Uses (examples): determining road networks, mapping building/structures, planning irrigation

2. Large-scale maps

   • Scale range given: 1:5000 to 1:250,000
   • Uses: regional planning, mapping, administration
   • Example mentioned: “Javanese map” (as referenced)

3. Medium-scale maps

   • Scale range given: 1:250,000 to 1:100,000
   • Uses: to display broader information in an area
   • Examples mentioned: district or province

4. Small-scale maps

   • Scale range given: 1:500,000 to 1:1,000,000
   • Uses: general planning and strategic studies
   • Coverage: usually across the territory of a country

5. Geographical scale maps (terminology as in subtitles)

   • Scale: 1:1,000,000
   • Uses: to describe the scope of the world

Summary (as conveyed)

• Maps have long been important for human activity and geography.
• Cartography is the study of maps, and cartographers are experts in maps.
• A map is defined through depiction on a flat plane with scale and projection, representing natural/man-made or other abstract elements.
• Maps can be distinguished from atlas/globe/imagery/plan.
• Maps are classified mainly by:
  • content (general vs thematic)
  • scale (cadastral, large, medium, small, and world-scale/geographical)

Speakers or sources featured

• Regulation No. 8 of 2013 (concerning spatial planning map accuracy)
• Geospatial Information Agency (BIGTA / “BIG” as mentioned in subtitles)
• International Geographic Association (as stated in subtitles)
• Music (non-speaking audio marker)
