Direct (Original) Data
Pros Cons
You get the exact data you need Data gathering may take a long time to collect.
You only gather as much or as little as you need Data gathering may be expensive as you hire other companies to get it for you.
You know exactly where the data came from and so you can estimate how reliable it is. It may involve having to purchase equipment such as data loggers and computers.
You may be able to sell the data for other purposes. It may not be possible to gather original data due to the time of year e.g. you want winter snowfall data and the project is now in the middle of summer.
