“I used to think that writing is the most trivial part of the job of a data scientist; because the analyses and numbers should speak for themselves right? Wrong!” ~ Xie (2024b)1

So What?

(Does a Spatial Data Scientist do?)

The ‘Pipeline’

  • Code
  • Tidy
  • Analyse
  • Understand
  • Communicate
  • Report

How to Understand?

How should we do this?

This is the method that matches the need.

How to Communicate?

Tell Me a Story

All data science is, ultimately, a story.

Tell Me a Story

All data science is, ultimately, a story.
Focus on the ‘so what’.

Tell Me a Story

All data science is, ultimately, a story.
Focus on the ‘so what’.
Don’t bury the lede.

Tell the Right Story

(And that requires soft-skills)1

All Change?

We think the story is the stable part, because everything else in data science is always changing. Here’s one vision from Analyst Uttam (2025):

Old Data Science Role New Job Title
Data cleaning & ETL Analytics Engineer (SQL + dbt + Airflow )
Business dashboards BI Developer (Power BI, Tabley, Looker)
Product experimentation Data Analyst (SQL + experimentation)
ML Modelling ML Engineer (MLOps, pipelines, deployment)
Causal inference/forecasting Research Scientist (Stats + PhD-level modeling)
