New #introduction after migrating to Hachyderm.io - I work in data/research for a dog welfare and rehoming charity, mostly using #RStats, #Python and #SQL with occasional #QGIS.

I’m also interested in the environment, climate and wildlife. I don’t have loads of free time these days but I also enjoy music (see Bandcamp link!), books when I get round to reading them (see Bookwyrm link!), films (anything from highbrow to Highlander), cycling, yoga and #TaiChi (initially as ways to help manage #arthritis, before I began to appreciate both in their own rights).

I've now published a write-up and the source code for how I calculated a connectivity rank which could be used to help prioritize how a bike network is built out based how segments would improve connections with the existing network.

Thanks to all the open source mapping projects that helped make this possible, including #qgis #valhalla #josm and #turfjs. And yes, I used JavaScript for this.

Feedback, improvements welcome!

You can look upthread to see how I generated the isochrones yesterday. The hex grid used here is just a standard hex grid. So all I did today to finish was to use those isochrones to calculate the rank, and then I pulled everything back into #qgis to visualize.

I may throw the code up into a public repo in case others are interested.

Continued thread

I only want to test the travel distance along the current and planned low-stress network. But routing engines normally generate isochrones against anything that's bikeable in #OpenStreetMap.

Here's how I solved that. Starting with geo-data for the current and planned low-stress network, I loaded into #QGIS and then exported back out to GeoJSON, then imported back into #JOSM. From there, I added tags to entire network to mark them as bike routable. 🧵

Oh well, here we go again with another instance change for me because thanks to @joeroe we have an archaeology themed instance!
#introduction:

I'm a landscape archaeologist based in Rome. I did my PhD on spatial distribution of #IronAge archaeological sites along the Euphrates.

Currently, I am working on #remotesensing tools applied to #culturalheritage and #landscapearchaeology in #WesternAsia.

I have been an #R and #QGIS user for a few years now, and love everything about them.

#ReIntroduction

Curious. Introspective. An aging idealist trying not to be too inflexible. Hope to leave things in a better place. We are never too old to re-assess our direction.

Process ideas visually through photography #darktable. Explore new music in #Bandcamp, then purchase for #Jellyfin in lossless #FLAC.

Graduated from Art School in Portland Or, and wish I had overlapped with #QGIS back then.

Tend to avoid "Rent to Never Own" revenue models.
