ACTUAL Exam Questions and CORRECT
Answers
What is spatial data analysis? - CORRECT ANSWER - A set of methods to examine,
manipulate, analyze, and interpret geospatial data to understand spatial patterns and
relationships.
What are the goals of spatial data analysis? - CORRECT ANSWER - To support research,
decision-making, and planning through understanding of geographic patterns and causes.
What are the six high-level categories of spatial analysis according to ESRI? - CORRECT
ANSWER - 1. Understanding where 2. Measuring size, shape, and distribution 3.
Determining how places are related 4. Finding the best locations and paths 5. Detecting and
quantifying patterns 6. Making predictions
What are spatial queries? - CORRECT ANSWER - Queries that involve geometric or
topological relationships between layers, such as "within" or "intersects".
What are attribute queries? - CORRECT ANSWER - Queries that select features based on
attribute values.
What are examples of geometric measurements? - CORRECT ANSWER - Distance, area,
perimeter, angle.
What are types of distance measurement? - CORRECT ANSWER - Euclidean, geodesic
(spherical), network distance, and cost surface.
What is a cost surface? - CORRECT ANSWER - A raster that represents the "cost" of
moving across a landscape, e.g. elevation or slope.
, What is spatial distribution? - CORRECT ANSWER - The way objects or phenomena are
arranged in space.
What is proximity analysis? - CORRECT ANSWER - Techniques to analyze spatial
relationships based on distance.
What is a buffer in GIS? - CORRECT ANSWER - A zone around a feature defined by a
specified distance.
What are use cases of buffers? - CORRECT ANSWER - Identifying features within
walking distance, service coverage, impact zones.
What is a distance matrix? - CORRECT ANSWER - A table showing distances between
pairs of features.
What is a nearest neighbor analysis? - CORRECT ANSWER - Measures proximity
between features and detects clustering or dispersion.
What are Thiessen polygons (Voronoi diagrams)? - CORRECT ANSWER - Polygons
where each location is closer to its own seed point than any other.
What is density analysis? - CORRECT ANSWER - Analyzes concentration of features to
identify hotspots.
What is classification in spatial analysis? - CORRECT ANSWER - Grouping data into
categories based on attribute conditions.
Why can maps using the same data appear different? - CORRECT ANSWER - Because of
different classification schemes or color symbology.
