What is spatial interaction in AP Human Geography?
Spatial Interaction. the movement of people, goods and ideas within and across geographic space . Spatial Search. the process by which individuals evaluate the alternative locations to which they might move.
What is an example of spatial interaction?
SPATIAL INTERACTION IS A dynamic flow process from one location to another. ... A workplace such as a factory or office tower is an example of a place with a demand for labor, while a residential neighborhood provides a source of workers.
Which factors determine spatial interaction between two regions?

What are spatial interaction models?
A spatial interaction model is a mathematical model that predicts the movement of people between origins (usually their homes) and destinations (health facilities) by examining the distance between them . ... Such models are one of the more complex ways of deciding where to locate a new health facility.
Globalisation propels and is propelled by spatial interaction – the connections and relations that develop among places and regions as a result of the movement or flow of people, goods, or information .
What is spatial process in geography?
Spatial processes are processes taking place in space and may depend on location in space . They show different natures and are studied in different disciplines like ecology, geography, geocomputation, and physics. Exam- ples are the spread of forest fires (Yuan 2001), the growth of cities (Batty et al.
What is spatial perspective in geography?
The Spatial Perspective
A historical perspective focuses on the temporal dimension of human experience (time and chronology), while geography is concerned with the spatial dimension of human experience (space and place) . ... Understanding spatial patterns and processes is essential to appreciating how people live on Earth.
How does distance affect spatial interaction?
The distance decay effect states that the interaction between two locales declines as the distance between them increases . Once the distance is outside of the two locales’ activity space, their interactions begin to decrease.
What do you think are some good examples of items shared through spatial interaction? Art, food, or other items that are known to one of the groups but not the other .
What are spatial associations?
Spatial association means connectedness or relationship between and among variables over space . ... Many variables may be associated one with another at one or more sites. If there is spatial interaction there is also spatial association. Maps can depict spatial association.
What are spatial patterns?
The spatial pattern of a distribution is defined by the arrangement of individual entities in space and the geographic relationships among them . The capability of evaluating spatial patterns is a prerequisite to understanding the complicated spatial processes underlying the distribution of a phenomenon.
What are the components of spatial flow?
- Geographical. Each flow has an origin and a destination and, consequently, a degree of separation. ...
- Physical. Each flow involves specific physical characteristics in terms of possible load units and the conditions in which they can be carried. ...
- Transactional. ...
- Distribution.
Which is an example of a spatial organization?
My child’s daycare center uses a developmental game in which they put a pile of differently colored lego blocks and set of cannisters with the names of colors on them in front of the child . This is not only a good developmental exercise, it is a good example of Spatial Organization. ...
What is time space convergence in human geography?
Time–space convergence (TSC) refers to the decline in travel time between geographical locations as a result of transportation, communication, and related technological and social innovations .
What is interaction model of communication?
The Interaction Model of communication (see Figure 1.4) describes communication as a process in which participants alternate positions as sender and receiver and generate meaning by sending messages and receiving feedback within physical and psychological contexts (Schramm, 1997).
Who gave the spatial interaction model?
The fundamental concept developed by him is known as ‘Ullman’s Principles’ or ‘Ullman’s Traid’. Ullman (1954, 1957, and 1973) put forward three main reasons of the interactions involving transportation: (i) Complementarity (ii) Intervening opportunity, and (iii) Transferability.
What is spatial perspective?
Spatial Perspective. Way of identifying, explaining, and predicting the human and physical patterns in space and the interconnectedness of various spaces .
In what ways are places on Earth connected?
Humans and places are connected on Earth through language, religion, ethnicity, culture, climate, transportation, and more . Globalization can be defined as the increasing connection of economic, cultural, and political characteristics across the world.
How does globalization create or show connections across Earth?
How does globalization create or show connections across Earth? [ Globalization provides an opportunity to diffuse ideas , as well as learn about other places (including the cultural landscape).]
What are spatial observations?
Spatial observation data includes both data of conventional entities and also samplings over multi-dimensional spaces . ... It integrates the management of entities and samplings within a simple data model based on the well known mathematical concept of function.
What are some geographic factors?
Geography, which is the study of the Earth’s surface, focuses on elements such as the arrangement of physical features, climate, soil and vegetation . Geography influences the development of the people who occupy given areas.
What are examples of spatial patterns?
Types of spatial patterns represented on maps include absolute and relative distance and direction, clustering, dispersal, and elevation .
What are the 3 geographic perspectives?
The matrix of geographic perspectives. Geography’s ways of looking at the world—through its focus on place and scale (horizontal axis)—cuts across its three domains of synthesis: human-societal dynamics, environmental dynamics, and environmental-societal dynamics (vertical axis) .
What’s spatial location?
Spatial data is any type of data that directly or indirectly references a specific geographical area or location . Sometimes called geospatial data or geographic information, spatial data can also numerically represent a physical object in a geographic coordinate system.
What are spatial regions?
Spatial region filtering allows a program to select regions of a FITS image to process using simple geometric shapes and boolean combinations of shapes. When an image is filtered, only pixels found within these shapes are processed. Spatial region filtering is accomplished by means of region specifications.
What is interaction in geography?
The definition to geographical interaction is how humans change the Earth . ... This included taking apart the earth’s elements (e.g. oceans, terrestrial ecosystems, atmosphere, hydro-logical systems) and separately studying each on and how they’re influenced, and connected to, the other parts of the Earth system.
What are 3 examples of professions that use geographic skills?
- Cartographer.
- Commercial/residential surveyor.
- Environmental consultant.
- Geographical information systems officer.
- Planning and development surveyor.
- Secondary school teacher.
- Social researcher.
- Town planner.
What are the six important considerations of spatial approach?
What are the important considerations of spatial approach? location, distance, direction, orientation, pattern and interconnection .
Our results support the idea that geographic distance strongly affects technology adoption patterns and the friendship connections that users establish on online social networks; however, the intensity of interaction on social ties seems unaffected by distance, with negligible differences in how users interact with ...
How are pollutants an example of interconnections among places?
What is regionalism? Dividing a city or state into separate regions. How are pollutants an example of interconnections among places? Places with the same pollutants could have similar ways of life.
What influences spatial interaction?
Spatial interaction is a basic concept that considers how locations interact with each other in terms of the movement of people, freight, services, energy, or information. Complementarity, intervening opportunity, and transferability are the three bases for spatial interactions.
What is the gravity model of spatial interaction?
The Gravity Model holds that the interaction between two places can be determined by the product of the population of both places, divided by the square of their distance from one another . The primary implication of this model is that distance is not the only determining factor in the interaction between two cities.
How did environmental determinism impact culture?
Environmental determinism is the belief that the environment, most notably its physical factors such as landforms and climate , determines the patterns of human culture and societal development. ... These different outlooks then spread throughout a population and help define the overall behavior and culture of a society.
What are the 3 types of spatial distribution?
Dispersion or distribution patterns show the spatial relationship between members of a population within a habitat. Individuals of a population can be distributed in one of three basic patterns: uniform, random, or clumped .
What types of spatial patterns are represented on maps?
Types of spatial patterns represented on maps include absolute and relative distance and direction, clustering, dispersal, and elevation .
What are spatial variations?
A difference or variation (in terms of population, population density, gross domestic product (GDP), life expectancy) over an area of the earth’s surface.
