The End of GIS: AI!
The AI Revolution is Coming for GIS: What You Need to Know About Microsoft’s Latest Warning is a pretty dire read...but you probably should add 5-10 years to this timeline. Here are a few take-home messages for me:
- The impact will be most-significant on the entry-level jobs.
- But, field work and basic project management will still be around for a while.
- Coding is still a key skill, but it will be all about AI-assisted coding in the very near future. But, you will need to have a good understanding of coding and how AI 'thinks' in-order to effectively prompt the AI.
- Take an online class in maschine learning for geospatial applications.
- Combine GIS expertise with complementary skills such as urban planning, environmental science, and more.

Projections & Distances
Geodesic or planar: which to use for distance analysis (by Esri) is a nice overview of the issue. Take-home message: use geodesic distances!

The Copernicus Interactive Climate Atlas
The Copernicus Interactive Climate Atlas is awesome - have a look! You can display measurements, reanalysis, and model data at all kinds of geographies & time scales. And: download the data in a bunch of formats.
It is just too much...nobody will use it. Expert scientists will access the data directly and the general public will scared off by the complexity. This is really designed for the rare 'regular' person who is interested & competent enough to figure-out the tool.
Suggestion: Make a simplified version or walk-through video.

Open Pedagogy in GIS Education
- There's nothing inherently 'bad' about commerical GIS products (= Esri products) and there's nothing inherently 'better' about open-source GIS products - it's all in the way that you use them for teaching & learning.
- GIS teaching & learning does not all of the sudden become 'active' or 'inquiry-based' or 'diverse' or 'participatory' when you use QGIS & an open-source book.
- The vast majority of employees that hire my students use Esri products.
- The biggest challanges for open-source GIS products: 1) there is no pratical solution for a Web GIS and 2) for GIS apps.
- I will continue to use the Esri GIS products.
