Today, we will discuss 'site.' Can anyone tell me what they think site refers to in the context of remote sensing?
Is it about the location of something?
Exactly! Site refers to the geographic or topographic location of objects. It's crucial for identifying features based on their surroundings. Can anyone think of examples?
Like different tree species growing in different types of soil or land?
Great example! Tree species occur on various site types, such as well-drained upland or poorly drained lowland sites. Let's keep that in mind as we move forward.

Now let’s shift our focus to 'association.' What can you tell me about how association is related to site?
Does it have to do with how features connect or relate to each other?
That's correct! Association refers to the relationship between different features based on their proximity. Can someone provide an example?
I think commercial properties often cluster around main roads and highways, right?
Exactly! That’s a perfect example of association. Understanding these relationships helps improve our spatial analyses.

How do you think site and association work together in spatial analysis?
Well, knowing where something is can help us know what other features might be close by.
Great connection! The site's characteristics can help predict the relationships (association) with nearby features. Can anyone think of another example illustrating this connection?
Snow cover in higher elevations means other cold-related biological features might also be present.
Excellent point! The association of features based on site characteristics is fundamental in remote sensing and GIS applications.
Introduction & Overview
Read summaries of the section's main ideas at different levels of detail.
Quick Overview
Standard
The section discusses site, the topographic or geographic location of objects, and association, the relationship between features. Examples like species distribution based on site type and commercial properties linked to transportation routes are provided to illustrate these concepts.
Detailed
Site and Association
Overview
This section delves into the critical concepts of site and association in remote sensing and spatial analysis. Understanding these terms aids in interpreting geographic and spatial data more effectively.
Site
- Definition: Site refers to the geographic or topographical location of objects. This aspect is crucial for identifying features based on where they are situated in relation to their environment.
- Examples:
- Certain tree species thrive on well-drained upland sites, whereas others prefer poorly drained lowlands.
Association
- Definition: Association involves studying the relationships between different features or objects located near each other. It emphasizes how the presence of one feature can suggest the presence of another.
- Examples:
- Snow cover is commonly associated with higher elevation zones.
- Commercial properties tend to cluster around main transportation routes.
Maintaining an understanding of these concepts is essential for effective spatial analysis in various applications, especially in remote sensing and geographic information systems (GIS).

Chapter Content
Site refers to the topographic or geographic location of objects. It is an important clue in the identification of certain types of features (Figure 5.38). For example, certain tree species would occur on well-drained upland sites, whereas other tree species would occur on poorly drained lowland sites.
Detailed Explanation
The term 'site' is significant in the context of remote sensing as it describes the geographic or topographical location of features in an image. Different species of trees, for example, have specific preferences for their growing conditions. Some trees thrive on upland sites that are well-drained, meaning they don’t retain water, while others prefer lowland sites that can hold moisture, which allows the trees to draw in necessary water for growth. This relationship helps in identifying tree species from remote images based on their location.
Examples & Analogies
Think of a gardener who distinguishes between two types of plants. One type of plant grows best in sunny, elevated gardens (upland), while the other flourishes in damp, shady areas (lowland). Just like the gardener uses soil type and moisture to decide where to plant, remote sensing experts use site information to determine where certain species might be found in images.

Chapter Content
Association refers to the presence of certain features in relation to others. It takes into account the relationship between the recognizable objects/features in proximity to the object to be identified. For example, the snow cover is related to higher elevation zones, commercial properties are associated with major transportation routes.
Detailed Explanation
Association involves understanding how different features are related based on their spatial proximity. For instance, certain environmental conditions, like snow cover, commonly occur in regions at higher elevations. Similarly, commercial areas tend to be located near major roads and transportation routes to facilitate better access. By examining these associations in remote sensing data, analysts can deduce information about land use and the types of features present in an area.
Examples & Analogies
Consider a shopping mall in your town. You’ll likely find it near major highways and streets because that location encourages customers to visit. Similarly, remote sensing analysts look at spatial associations to understand why certain features exist together—like snow in mountain areas or shops near busy roads.
Key Concepts
-
Site: The geographic location of an object important for identifying features in remote sensing.
-
Association: The relationship between features that helps in understanding their proximity-related characteristics.
Examples & Applications
For instance, certain tree species found on well-drained upland sites versus poorly drained lowland sites.
Another example includes commercial properties often found along major transportation routes.
