Are you curious about the "Future of GIS"? If yes, tune in to episode 290. of the **#geomobpod **to hear about discrete global grid systems from Instituto Superior Técnico lecturer @luis_de_sousa.

He provides an overview of what DGG systems are, the challenges of existing systems like H3 and why they could prove to be so important in the future.

Enjoy:

De la complejidad de WFS a la simplicidad de OGC API – Features - Blog IDEE

¿Te frustra consultar servicios WFS con «endpoints» kilométricos? ¿Quieres obtener todas las direcciones de un código postal? Si es así, este artículo es para ti. Por suerte, las OGC API - Features han llegado para facilitarnos la vida: peticiones simples, formatos modernos como JSON o GeoJSON y una estructura que cualquier desarrollador entiende a la...

@IvanSanchez Good point :-) This approach theoretical approach assumes they could be walking across buildings...

@doublebyte I got the data from the QGIS training manual: https://docs.qgis.org/3.40/en/docs/training_manual/processing/john_snow.html

@cwillmes yes: it was the broad street pump. Once it was closed, the cholera cases dropped!

The analysis using #Thiessen polygons shows an even more evident concentration of cholera cases around the broad street pump #Voronoi #SnowAnalysis #SnowKaggle #GIS #BTS

@doublebyte but the point of the spatial analysis is to find the contaminated pump. The pump locations (red dots) are the "center" points of the constructed thiessen polygons... "winner" is the polygon with the most colera cases.

@doublebyte yes, I know! I use this data set in my spatial analysis class to teach the students point pattern analysis. :)

@doublebyte That tesselation doesn't take into account the shape of the street network, though.
Or, to put it in another way: people don't walk from a house to a pump in a straight line.
