Distribution Maps and Data Analysis

This video tutorial explains how to create distribution maps using a GIS viewer. It covers setting up the viewer with a QD a minor project, plotting data on shapefiles, and using point layers for data visualization. The tutorial also demonstrates how to map statistics on numerical variables, such as average and sum, to analyze crime data in San Francisco. The video provides step-by-step instructions on adjusting map appearance and interpreting data through thematic maps.

What is the primary purpose of creating distribution maps using a GIS viewer?

• To design urban infrastructure

• To analyze weather patterns

• To create 3D models of geographic regions

• To visualize point density and demographic information

Which project is used as an example for creating a distribution map in the video?

• A QD a minor project with weather data

• A QD a minor project with crime reports from San Francisco

• A project on global warming

• A project on wildlife conservation

What can be adjusted to change the appearance of a distribution map?

• The type of data source

• The color and opacity settings

• The type of map projection

• The geographic region

How is data plotted on shapefiles in a distribution map?

• By using a 3D modeling tool

• By selecting the value in polygon layer radio button

• By manually drawing the data points

• By importing data from a spreadsheet

What does each color represent in the distribution map of square mileage?

• A different type of crime

• A range of square mileage

• A specific geographic region

• A time period

What is the second method of plotting data on a distribution map?

• Using data from a satellite

• Using data computed from point layers

• Using data from a weather station

• Using data from a survey

What type of data is used to analyze personal crime in the video?

• Data from a financial report

• Data from a weather report

• Data from a wildlife survey

• Data from point layers in a QD a minor project

What statistical measures can be mapped on numerical variables in a distribution map?

• Maximum and sum

• Variance and standard deviation

• Mode and range

• Minimum and median

What does the average threat level of personal crimes indicate in the distribution map?

• The economic status of a region

• The number of crimes in a region

• The level of violence associated with each type of crime

• The geographic size of a region

What are the two methods of plotting data on a distribution map discussed in the video?

• Using shapefiles and satellite images

• Using shapefiles and data computed from point layers

• Using satellite images and survey data

• Using survey data and weather reports
