  1. Enhancing Web Map Performance in ArcGIS Online Julia Guard & Melanie Summers

  2. Questions to ask before creating a 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? Enhancing Web Map Performance in ArcGIS Online

  3. Case Study: Mapperville, Michigan • The citizens of Mapperville are in need of current land parcel information with reference data for neighborhoods and roads • The community needs to know: parcel ID, parcel owner & acreage • The map needs to be simple, clear and easy for anyone to use. • Available through a browser, iOS or Android device Enhancing Web Map Performance in ArcGIS Online

  4. What information is important? • Maximum number of records returned by the server • Number of feature layers in the service • Number of attribute fields As the amount of data goes up, the performance of the web map goes down. Enhancing Web Map Performance in ArcGIS Online

  5. Who will be using this web map? • 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 • Fill in useful Metadata ArcMap ArcGIS Online Enhancing Web Map Performance in ArcGIS Online

  6. How will the map or application be accessed? • File Layer • Less than 1000 features • Not updated frequently or by multiple people • Feature Service • If possible, disable editing on your services • Remove all filters on your data Enhancing Web Map Performance in ArcGIS Online

  7. What functionality do the users need? • Complexity of feature geometry: consider using the Simplify Line or Simplify Polygon tool • Edit settings: should the layer be read-only? Enhancing Web Map Performance in ArcGIS Online

  8. What functionality do the users need? • Tiles hosted on ArcGIS Online support fast visualization of large datasets using pre-drawn map images, or tiles • Tiled map services run quickly on the web, but it takes an investment of strategic planning and storage space to build a quality tile cache • Tile layers are most appropriate for vector or raster data that is read-only and intended for use as a basemap • Methods: • Publish tiles from an ArcMapdocument • 2. Publish a tile package and upload to ArcGIS Online • 3. Publish a feature layer in ArcGIS Online Enhancing Web Map Performance in ArcGIS Online

  9. What type of experience am I trying to convey? • User-friendly • Fast • Informative • Data centric • Accessible • Focused • Functional • Relevant Enhancing Web Map Performance in ArcGIS Online

  10. Performance Improvements Data source: • Reduced number of feature layers • Refined the feature attribute information • Minimized the number of records returned by the server • Cached tiles • Simplified the feature geometry • Measurement tool = Service URL • http://services.arcgis.com/Wl7Y1m92PbjtJs5n/arcgis/rest/services/Mapperville_FS1/FeatureServer/3 Web map configuration: • Established visible scale ranges • Created Bookmarks • Configured pop-ups • Add labels • Measurement tool = User experience Enhancing Web Map Performance in ArcGIS Online
