Enduring Understanding:
Geographers use maps and data to depict relationships of time, space and scale.
Required Reading:
Essential Knowledge:
- Data may be gathered in the field by organizations or by individuals.
- Geospatial technologies include geographic information systems (GIS), satellite navigation systems, remote sensing, and online mapping and visualization.
| GIS Data System | Primary Uses | Benefits | Drawbacks |
| ArcGIS | Comprehensive spatial analysis, mapping, and geospatial data management | Industry standard, robust tools, large support community | High licensing cost, steep learning curve |
| QGIS (Quantum GIS) | Open-source mapping, data visualization, and spatial analysis | Free, open-source, cross-platform, active developer community | Less polished interface, fewer proprietary datasets |
| Google Earth Engine | Cloud-based geospatial data analysis at global scale with satellite imagery | Massive dataset access, powerful cloud processing, no local storage needs | Requires internet connection, limited offline capability |
| GRASS GIS | Advanced raster/vector analysis, geoprocessing, and modeling | Powerful open-source analytics for scientific research | Steeper learning curve, less intuitive for beginners |
| MapInfo Professional | Business mapping, location analytics, and geodemographics | User-friendly for business applications, strong customer segmentation tools | Proprietary with licensing costs, less suited for complex scientific analysis |
| Esri StoryMaps | Interactive web-based storytelling with maps and multimedia | Engaging public communication, easy integration with ArcGIS data | Less analytical depth, dependent on ArcGIS ecosystem |
- Spatial information can come from written accounts in the form of field observations, media reports, travel narratives, policy documents, personal interviews, landscape analysis, and photographic interpretation.
Word Bank!
Copy down the following word bank. You will use this regularly on FRQ questions as you describe spatial relationships in maps.
1. Location & Position
Absolute location — exact coordinates (latitude/longitude)
Relative location — location described in relation to other places
Proximity — nearness in space
Central / Peripheral — near the center or on the edge of a region
Adjacent — next to or adjoining
Contiguous — sharing a common border, touching
2. Direction
Cardinal directions — north, south, east, west
Intermediate directions — northeast, southeast, northwest, southwest
Relative direction — “upstream,” “downtown,” “inland,” etc.
Orientation — general alignment or facing
3. Distance
Absolute distance — measured in standard units (miles, km)
Relative distance — perceived distance affected by travel time or cost
Linear distance — straight-line measurement
Distance decay — interaction decreases with distance
Time-space compression — perceived shrinking of distance due to improved transportation/communication
4. Distribution Patterns
Clustered (concentrated) — close together in space
Dispersed (scattered) — spread apart
Linear pattern — along a line (e.g., road, river)
Radial pattern — radiating outward from a central point
Random pattern — no discernible order
Uniform distribution — evenly spaced
5. Spatial Interaction
Flows — movement of people, goods, or ideas
Connectivity — degree of connection between places
Accessibility — ease of reaching a location
Spatial association — relationship between the distribution of two variables
Network — interconnected system (roads, internet cables)
6. Regional & Scale Relationships
Core — dominant central area of activity
Periphery — less developed edge of a region
Hinterland — area served by a central place
Transitional zone — area where characteristics blend
Scale of analysis — local, regional, national, global
Spatial hierarchy — arrangement of phenomena from largest to smallest scale
7. Boundaries & Edges
Boundary — dividing line between regions
Border zone — area of transition between regions
Edge effect — changes that occur at the boundary of two regions
Fringe area — outer portion of a settlement or region
Contextualization:
This video breaks down how Google Maps collects information via Satellite.
In Practice:
Essential Question:
How have map making techniques advanced over time? Cite at least three specific examples (label them example 1, example 2 and example 3).
Conceptual Analysis Questions:
- What impact does the way geographical data is collected have on the information that can be presented? (Think of written accounts vs. Policy documents vs. Landscape analysis)
- What are the benefits of contemporary (technology based) map making? Are there any disadvantages that you can think of?
Vocab Review:
Provide a shorthand working definition for each of the following terms. This means it needs to be in YOUR OWN WORDS.
- Geospatial technologies
- Geographic Information Systems (GIS)
- Satellite Navigation Systems
- Remote Sensing
- Online Mapping
- Visualization
