Visualizing relativity btwn 2 GIS datasets, issues with CPs and Proximity

Hi all,

This is my first time posting - apologies in advance if the answer is obvious, I am very new to Grasshopper.

I am creating two scripts with imported GIS data to visualize relationships between housing, food accessibility, and parks in DC. My first map (image below) is attempting to connect each affordable housing location to grocery stores within a quarter-mile radius using lines. I thought I could use the Closest Points and Line components, but obviously I am missing something.

My second map is a fuzzy cloud grid that gradates colors depending on how many parks (between one and five) are within a half mile of an Affordable Housing complex (I hope to also change the size of the clouds depending on income data for each grid - holding off on this for now). Again, I’m realizing my CPs and Proximity components are not accurately capturing the relationship between the two variables and instead are just showing the density of parks.

Both scripts appear to be missing relativity - any tips on how I can best relate the Affordable Housing data back to the respective Grocery Store and Park data identified in the CPs components?

Thank you!

You might want to try grafting the Affordable Housing points first. Also, not quite sure what you are looking for with fuzzy cloud grid, but I took a pass at it by coloring a mesh and extracting the vertexes for the cloud.

Depending on how accurate you’d like to be, you could look into generating isochrones based on modes of transportation. I’ve added a component for the Mapbox Isochrone service to Heron which will be available in the next release.

Hi Brian,

This is much appreciated - thank you so much! I will give these scripts a try now :slight_smile:

Best wishes,
Erin

Just to follow up, a MapboxIsochrone component is now available in Heron v0.4.0.
