Geospatial Data Acquisition and Analysis Practice Questions
Course Introduction
Geospatial Data Acquisition and Analysis explores the principles and techniques for collecting, processing, and interpreting spatial data from diverse sources such as satellites, GPS, remote sensing platforms, and field surveys. Students will learn about methods for acquiring high-quality geospatial data, integrating various datasets, and applying analytical tools to address real-world problems in areas like urban planning, environmental management, and disaster response. Emphasis is placed on data quality, accuracy assessment, and the use of Geographic Information Systems (GIS) for visualization and analysis, providing a comprehensive understanding of how spatial information supports decision-making in multiple disciplines.

Q1) What are the four ways that the affine transformation may alter a dataset to match it up with another dataset?
Answer: The affine transformation will change the coordinates (and projection)of one dataset to match up with the coordinates (and projection of a second).It can do this by rotating (turning),skewing (slanting),scaling (altering the scale of the dataset),and translating (altering the placement of the dataset)the data.
Q2) Which of the following describes the use of a real-world coordinate system for identifying locations?
A)Spatial reference
B)Spatial analysis
C)Spatial scaling
D)Spatial projection
