2. Points to consider before creating the web map
Who will be using this web map?
What functionality do the users need?
What information is important?
How will the map or application be accessed?
What type of experience am I trying to convey?

3. Case Study: Hurricane Awareness – Brunswick County, NC
Who will be using this web map?
Brunswick County citizens, schools and businesses
What functionality do the users need?
Find closest shelter locations quickly and recognize areas of high risk
What information is important?
Awareness of emergency shelter locations, areas of risk, and street locations
How will the map or application be accessed?
Available through a web browser, iOS or Android mobile device
What type of experience am I trying to convey?
Map needs to be simple, clear and easy for anyone to use

5. Pre-publishing considerations
Maximum number of records returned by the server
How many layers are in the map and do they fit together?
Are all the attributes in each layer necessary?
General rule: as the amount of data increases, the performance of the webmap can decreases.

6. Complexity of the data
Complexity of feature geometry: consider using the Simplify Line or Simplify Polygon tool

8. Post-publishing considerations
Set a Visible Scale Range: layers set to automatically display only within an appropriate range of map scales
Minimum Scale: the smallest desired map scale (i.e. 1:50,000)
Maximum Scale: the largest desired map scale (i.e. 1:2,000)
Use Bookmarks: an item you can save to a map providing a shortcut to a position in the map

10. Data Type Options Feature Layer (Service) Feature Collection
Feature Service, Feature Collection, Tiled Service…
Feature Layer (Service)
Hosted feature layers support vector feature querying, visualization, and editing.
Performance Consideration
If possible, disable editing on your services
Remove all filters on your data
Feature Collection
Small amount of data, with only owner editing, added directly to the map
Performance Consideration
Does not need to be updated frequently
Is stored in the JSON of the web map

11. Data Type Options
Feature Service, Feature Collection, Tiled Service…
Tiles hosted on ArcGIS Online support fast visualization of large datasets using pre-drawn map images, or tiles
Tile layers are most appropriate for vector or raster data that is read-only and intended for use as a basemap
Pre-Publishing Considerations:
What layers can be incorporated
Storage space
Full Extent of map
Convert Labels to Annotation
Create needed Tile Levels only

12. Methods for Creating Tiled Services
1. Generate Tiles in ArcMap
does not consume tile generation credits
Create Tile Package and upload to ArcGIS Online, then Publish Service
2. Generate Tiles in ArcGIS Online
consumes tile generation credits
Publish directly Tiles from ArcMap or ArcGIS Pro
Publish Feature Layer
Map Tile Generation =
1 credit per 1,000 tiles generated
