Introduction to Geographic Information Systems by Chang 9th Edition-Test Bank

Geographic Information Systems (GIS) play a crucial role in mapping and analyzing spatial data. The 9th edition of “Introduction to Geographic Information Systems” by Chang covers key topics such as geometric transformation, image-to-map transformation, and more. Understanding these concepts is essential for anyone working with GIS technology.

### FAQ

#### 1) Why is geometric transformation necessary in GIS?
Geometric transformation in GIS is necessary to ensure accurate positioning of spatial data on different coordinate systems, allowing for seamless integration and analysis.

#### 2) What are the steps to transform a digitized layer into UTM coordinates?
The steps involve adjusting the digitized layer based on known longitude and latitude values of reference points on a map to convert it into UTM coordinates.

#### 3) What is image-to-map transformation?
Image-to-map transformation involves converting pixel coordinates from a raster image to geographic coordinates on a map.

#### 4) What does differential scaling do in affine transformation?
Differential scaling in affine transformation allows for non-uniform scaling of objects in different directions.

#### 5) What are the three sequential steps in the affine transformation of a satellite image?
The steps include rotation, translation, and scaling of the image to align it with a reference coordinate system.
