In this chapter, we discovered more about the way to query information from your map. Compared to a paper map, interactive feedback from a map is one of the most powerful features you can expect. We hope following our guidance was not too tough.

Starting with data manipulation, you learned more about the complex world of GIS. Next, we discovered about the dedicated components to select and query maps. Afterwards, with a pop-up, we inspected how to nearly reproduce the Push Pins map (you can always reproduce it as an additional task).

We created and modified our own geographical data instead of consuming existing data.
