We'll also see how HTML form elements (such as drop-down lists and radio buttons) can be used to provide end users with an interface for selecting subsets of larger datasets to visualize on the map.
Finally, we'll look at methods of dynamically acquiring the data for your map from some other site on the web. These methods include accessing data through a published web service and "scraping" data off of pages in which the desired information is not packaged in a convenient format.
The goal of the graded assignment in this lesson is for you to apply what you've learned in the course to produce a sophisticated mapping application of your choice. My expectation is that you'll work on something that goes a bit beyond the assignments you've already completed.
There are a number of directions you could take with this project. One of those directions would be to model your project after the examples in the lesson that demonstrate giving users the ability to map a part of a larger dataset. However, those of you who are looking for a bigger challenge might want to do something involving web scraping or database-driven mapping. (For the latter, I point you toward the optional database lesson and the database-related examples found here in this lesson.) I'm also open to you delving into some other advanced topic that we haven't touched on here. Examples include, but are certainly not limited to:
With the Google API:
- Custom tiles
- Handling large numbers/clusters of markers
- Polygon encoding (used to properly display donut polygons)
With the ArcGIS API:
- Query tasks/geoprocessing tasks
- Displaying arcgis.com web maps
- Extending an app developed with the Web AppBuilder
