How do I do this task (using Rstudio): Spatial filtering and aggregation:
In this task, firstly you will import all datasets. Then, you will filter all spatial data (TA, SA1, parks) based on Christchurch City TA. In case of SA1 you want only records that are in Christchurch City TA, for parks you want all records that intersects with Christchurch City TA. Then, you will summarise (sum) a SA1 population and area based on wards from the concordance file.
Hint: Check CRS of your layers and transform some if necessary.
Q1: What is the most and least populated ward in Christchurch City TA? (name and population)
