Becker- Week 4

Chapter 1

• ArcGIS- integrated collection of geographic information system software developed by Esri

• ArcGISPro- 64-bit desktop GIS application that uses a ribbon interface for 2D and 3D mapping

• Feature class- basic building block for displaying geographic features on a map

• • • Homogenous layer on map
    • Vector data with corresponding attributes for each feature

• Raster dataset- major type of spatial data that is a picture made up of a bunch of pixels

• File geodatabase- with extension.gdb that stores feature classes, raster datasets, and other related files

• Project- file with extension.aprx that contains one or more maps and related items

• Basemap helps orient users to location
  • ex:

• Catalog pane provides access to all components in ArcGIS project
  • Can create map with heading through this

Tutorial 1-2

• Learned how to find attribute data for a feature
• Learned how to zoom in on feature
  • 
• Spatial bookmarks allow you to zoom to preset map views
• Can right click feature to get attribute table

Tutorial 1-3

• Can change order of attributes, names and displayed names of attributes, see data types, delete attributes, and make only certain attributes visible
• Learned more about how to navigate attribute table

Tutorial 1-4

• Learning how to change symbols for feature classes (color, shape)
• Explored 3D maps
• 

Chapter 2

• Thematic map- consists of a subject layer/s (theme) placed in spatial context with other layers
• Make subject prominent while placing spatial context layers in the background

Tutorial 2-1

• Context layers often displayed using outlines with no color fill
  • Water features exception- blue color, no outline
  • 

Tutorial 2-2

• Learning how to label all layers of map
• Learned how to filter out duplicate labels

Tutorial 2-3

• Use definition query to limit features to a desired subset of the larger collection based on values in feature attribute table
• 

Tutorial 2-4

• Choropleth map- uses color in polygons to represent numeric attribute values

• • Use classification methods to display data (default method is natural breaks)
    • Uses algorithm to cluster values of numeric attributes into groups
    •  

Tutorial 2-5

• Learning to display polygon data in their centers

Tutorial 2-6

• Choropleth map showing population useful for studying needs like demand for goods and services
• Choropleth maps of normalized data provide different data than choropleth maps of total population
  • Normalized = segment of population divided by total population
• Density maps also form of normalized maps
• Can import and reuse symbology

Tutorial 2-7

• Dot density maps can be used to denote quantitative values
• Display a total number randomly across a statistical unit

Tutorial 2-8

• Visibility ranges automatically turn layers and labeling on and off, depending on zoom
• Small scale- 1:50,000,000
• Large scale- 1:24,000
• Can turn a feature layer on or off using visibility ranges

Chapter 3

Tutorial 3-1

• Building map layout that has two maps
• Had some troubles here loading second map
• Learned how to add legends beside maps
• Because of struggles displaying the second map, I wasn’t able to follow the instruction for the create charts section

Tutorial 3-2

• Learning how to publish and share ArcGIS maps online
• Learning how to access our maps using ArcGIS Online
• I realized I have been signed into somebody else’s ArcGIS Pro this whole time…
• 

Tutorial 3-3

• Learned how to create story on ArcGIS Online
  • Added various headers, subheadings, paragraph texts, and maps
  • 

Tutorial 3-4

• Dashboards- visual displays of data feeds in an easy-to-understand format, usually with map as center of focus

• Learned how to create a dashboard
• Had issues filling screen with map, so I couldn’t finish the very last part
