Activities and tasks expected to be completed in this section:
Based on skills acquired in earlier Esri Academy courses, the focus in this section will be on working with and editing of vector feature data, to be shared as web services at a later stage.
1) Make sure the indicated Esri Academy courses are completed!
2) Data acquisition. Set up your personal 'case study' exercise in an area you are familiar with. As the only requirement it should contain entities to be represented as point, line and polygon features. This could be a park in your vicinity with trees, paths and ponds; or an area with land cover (polygons), powerlines or roads (lines) and buildings (points); anything ...
In ArcGIS Online, go to your Content and select or create a folder, then click on New Item and select Feature Layer - Define your own layer. Next, you specify the Point, Line and Polygon layers (at least one each). After creating the feature layer follow the instructions given 'Describe your item below. Add fields on the Data tab. Configure editing on the Settings tab. Configure drawing and pop-ups through the map viewer or Visualization tab' with a focus of adding at least 1-2 suitable fields to each layer. Define a List of Values (Domain) for at least 2 fields. You can deactivate or simply ignore attachments.
To add data, return to Overview and open the layer in the Map Viewer. Select a suitable Basemap (e.g. Imagery) and zoom to your intended study area, perhaps setting a bookmark right away. In Layers, select your working layer and eg your points layer. Make sure editing is enabled. Activate the Edit tool on the right side menu, click on a location and start creating features for each of the point/line/polygone categories. Make sure you explore the snapping option for the latter two.
Close the Editor. Click on features to inspect the assigned attributes. Save the map for later sharing it in your ePortfolio. Go back to Content, open the layer description and inspect the added features.
3) Attribute join
Open a new map in the ArcGIS Online Map Viewer. Add the layer 'World Country Boundaries' from the Living Atlas and check out its characteristics. Then open https://data.worldbank.org/indicator/SP.POP.TOTL and download a .csv file containing e.g. population totals. Go to Content - New Item and drag the .csv over the upload box. Inspect the fields, and upload as a hosted service without geocoding. Check the imported table, and note there are multiple entries per country, e.g. for the years 2017-2020.
To connect the Worldbank demographic data with the country boundaries for further visualisation and analysis, join using the fields 'ISO 3 DIGIT' and 'LOCATION'.
... (this currently only is possible in Map Viewer Classic. For (new) Map Viewer, wait for fall 2022 release.
4) OpenStreetMap editing (optional)
An excellent way to practice vector feature editing is by signing up to https://www.openstreetmap.org, then choosing the online editor iD and experimenting with adding some detail in an area you are familiar with (
