Steps to apply EDA to the whole of Spain

Integrating electrofishing data into the dbeel

Spain electrofishing data?

Dams

• Import dam data into postgres
• Build the table joining dam data
• Run R program to calculate the cumulated number of dams from the sea.
• Run R program to calculate the cumulated score
  Spain dams?

CLC Corine Land Cover

• Run the program to calculate the clc numbers
• Run sql script
• Run R program
  Spain clc?

Caracteristics of river network

• Run the program to calculate the distance to the source, distance to the sea, upstream catchment
