Challenge #204: Updating Brazil

A solution to last week’s challenge can be found here.image source: https://en.wikipedia.org/wiki/States_of_Brazil

Did you know that Brazil is the largest country in South America? “Super legal!” you say to yourself em Português. Brazil is also an incredibly diverse country with many unique geographic regions. That’s why it’s a good idea to bring a map.

Unfortunately, the map I found is from 1920 and doesn’t show all 27 states (26 and the Federal District). Your task is to use the supplied data to update the map from the 22 existing states to include all 27.

Additionally, the capital moved from Rio de Janeiro to Brasilia in 1960, so the updated state of Rio de Janeiro should regain the land occupied by the Federal District in the 1920 map.

Boa Sorte!

Not sure if purposeful but nice timing to reference Brazil with Carnaval going on right now!

Cheers from Rio de Janeiro!

My solution. Probably a more efficient solution, but time is short this morning.

Here's my solution.

Step1: Process Federal District to merge with Rio

Step2: Remove parts of Old States that now belongs to New ones.

Step3: Combine all processed areas to generate final map.

I don't use spatial tools in my daily business, so it's usually a challenging task - but always interesting.

Just when I think I finally have a handle on spatial tools... Sometimes it seems like spatial process is doing the OPPOSITE of what I want it to. I guess I need more practice :S

Really a lot of fun, and some things I didn't know about Brazil!

Fairly simple if you know how to use spatial process tool and the summarize (spatial combine).

I am not sure this is quite right, but it appears to be accurate compared to the final picture.

I really enjoy working with spatial!

There are a couple of "extra" selects in my workflow because I really don't like to see warnings in the log.

A bit of Trial and Error, but I got to the end result. 🙂

A little while since I've done a spatial challenge, so this was a nice refresher

This was a fun learning one, I didn't go with the spatial process tool to do my 'cookie cutting' and instead went for the multi-row.

Good spatial practice! The tricky part about this one was trying to keep the workflow tidy!

@Blake 's video walk-through was key to get this solved.

I should have called my workflow "Pra que simplificar quando se pode complicar?" XD Used more tools that the necessary, but got there! Saudade da terrinha!
