Getting to Know Web GIS. Pinde Fu

submitted my homework URL, but my professors can’t access it. Why? How can I fix this problem?Answer: First, make sure your layer(s), web map, and web app for this assignment are all shared with the public. Next, check if your organizational settings allow anonymous access. Refer to step 7 in section 1.1. If you still have the problem, go to http://storymaps.arcgis.com/en/my-stories/, sign in, and click the Check Stories button to find the causes.

      5 Should I enable my ArcGIS Online organization to use HTTPS only?Answer: It depends. In general, it is recommended that you enable HTTPS only, which gives you enhanced security. If you enable HTTPS only, this implies that all the services and layers that your web maps and apps will be using must be configured to support HTTPS because web browsers do not allow the mixing of HTTP and HTTPS content. Some organizations still have map services and geoprocessing services running on the ArcGIS Server that doesn’t have HTTPS configured. These services can be loaded via HTTPS. If you will use such services in your web maps and apps, you should disable the HTTPS only option (refer to step 5 in section 1.1.).

      6 I need to upload my photos to a web server to get their URLs. Is there a web hosting service that you would recommend?Answer: There are many ways to upload and host your photos. Here are a couple easy ways:Upload your photos to https://imgur.com, and then find the direct links to each photo.Upload your photos to ArcGIS Online. Refer to https://blogs.esri.com/esri/arcgis/2018/01/05/photos-images.Upload your photos to Flickr, and then import them to your map tour app.

      7 I can drag and drop my CSV to the map viewer directly. How does this layer differ from a hosted feature layer?Answer: The former can be used for quick demos of small amounts of data, but it is not recommended in general. The latter has better reusability, supports larger data sizes, and supports more operations.Embedded layers (layers added to web maps directly)Hosted feature layer and feature serviceStorageThe data is stored or hardcoded in the web map.The data is stored in its own layer. Web maps just store a reference to this layer.Data size limitationLimited. Up to 1,000 features per layer, or 250 features per layer if using geocoding.1G per hosted feature layer;unlimited for feature services (requires ArcGIS Enterprise).ReusabilityNot reusable. To use the data in a different web map, you would have to add the CSV to the web map one more time. This essentially creates another copy.Reusable. You can reference a feature layer—one copy of truth—in as many web maps and apps as you want.CapabilitiesDoesn’t support query, search, and charting in most ArcGIS client apps such as Web AppBuilder for ArcGIS.Support query, search, and charting in most ArcGIS client apps such as Web AppBuilder for ArcGIS.

      8 It’s slow to upload my photos to a web server and find the latitudes/longitudes of these photos manually. Are there ways to create Story Map Tour apps without me having to upload photos and locating them myself?Answer: This tutorial teaches the generic workflow from data > layer > web map > web app. This workflow is applicable when you create web apps using other templates or app builders.You can create map tour apps using many other ways, some of which are easier though they are specific to the map tour template. For example, you can use Story Map Tour Builder, and choose to upload your images. This approach will upload your photos for you. If your photos are geotagged, the location of each photo is automatically extracted. Refer to http://storymaps.arcgis.com/en/app-list/map-tour/tutorial for more details.
