Tile layers, map image layers, and on-premises Web GIS Chapter 5 Tile layers, map image layers, and on-premises Web GIS Instructor These slides are for Getting to Know Web GIS, third edition (Esri Press 2018).

Chapter objectives Understand the needs for on-premises and hybrid Web GIS. Know ArcGIS Enterprise and its components. Understand the concept of portal collaboration. Know the differences and similarities of vector tile, raster tile, and map image layers. Become familiar with the workflow to publish web layers using ArcGIS Pro. Explore and use web layers in web maps. Create web apps for side-by-side comparison. This chapter is long. It can be split into two meetings: One focuses on ArcGIS Online standard analysis tools The other focuses on custom web tools (i.e. geoprocessing services) and big data tools (i.e. GeoAnalytics tools) Getting to Know Web GIS, third edition

+ + + Components ArcGIS Web Adaptor Integrates with your existing web server and appropriately distributes incoming requests for access to ArcGIS Enterprise. + Portal for ArcGIS The web frontend and infrastructure backend that supports a user’s interaction and overall experience with your Web GIS. + ArcGIS Server Gives you the ability to publish services and share maps and layers from your own business databases. The Web Adaptor acts as the gatekeeper of sorts to your ArcGIS Enterprise. It integrates with your existing web servers, where it takes requests and routes them appropriately to the related components of ArcGIS Enterprise. This location is also where web-tier security would be implemented for your ArcGIS Enterprise. + The ArcGIS managed data repository that stores the content hosted on the portal. It is not a replacement for your enterprise geodatabases. ArcGIS Data Store Getting to Know Web GIS, third edition

Tutorial Share a raster tile layer, a vector tile layer, and optionally a map image layer (require ArcGIS Enterprise). Create a web app to compare the performances of these layers. Finished product sample available here: Getting to Know Web GIS, third edition

Summary ArcGIS Enterprise enables on-premises and hybrid Web GIS deployment. Publishing services including dynamic map, geoprocessing, stream, image services requires ArcGIS Enterprise. ArcGIS Enterprise is 1 product, with 4 components, 2 user levels, 3 data store types, and 5 license roles. Map image, raster tile, vector tile, and feature layers fit for different needs. Creating app with ArcGIS Enterprise is basically author resources, publish/share services, and use the services. Getting to Know Web GIS, third edition

Assignment Publish a raster tile layer and a vector tile layer, and compare the layers side by side in a web app. Data is at C:\EsrIPress\GTKWebGIS\Chapter5\Assignment.gdb Be careful with the size of the raster tiles that will be generated. Keep the size small (<40MB) so that you can complete your homework quickly and the tiles won't take too much space in your portal. Submit URLs to the item details pages of your web layers. URL to your web app. A paragraph summarizing the differences between raster tile layers and vector tile layers. Getting to Know Web GIS, third edition
