ESRI - Exploring GIS Maps UPDATED
ACTUAL Exam Questions and CORRECT
Answers
basemap - CORRECT ANSWER - A map depicting locational reference information, such
as landforms, roads, landmarks, and political boundaries.
feature - CORRECT ANSWER - A representation of a real-world object on a map.
GIS - CORRECT ANSWER - Geographic information system. GIS uses interactive maps
to analyze data and help answer questions about the world.
layer - CORRECT ANSWER - A collection of related features in a GIS map. The features
in a layer usually have the same theme, geometry, and set of attributes.
For example, a GIS layer might use lines (geometry) to represent streets (theme) and include the
name of each street (attribute).
scale - CORRECT ANSWER - The ratio or relationship between a distance or area on a
map and the corresponding distance or area on the ground. Scale is commonly expressed as a
fraction or ratio.
Example: A scale of 1:1,000,000 means that 1 unit on the map equals 1 million units on the earth.
In other words, 1 inch on the map shows 1 million inches on the earth (about 189 miles).
spatial analysis - CORRECT ANSWER - The process of examining the locations,
attributes, and relationships of features in spatial data to address a question or gain useful
knowledge.
Map location - CORRECT ANSWER - You can use a map to determine where things are
in relation to each other.
