PySAL is an open source cross-platform library of spatial analysis functions written in Python. It is intended to support the development of high level applications for spatial analysis. https://us02web.zoom.us/j/84105444598
hiiii @sjsrey , I have made necessary changes in the PR
Hi all, This is my very first appearance here 👋🏽 but I admit I've following some of the PySal moves for a little while with a bit of a silent approach. Today I'm breaking that with my draft proposal for this year's GSoC for the Network Simplification project.
Thanks a lot! I'll have a look later today or tomorrow. From the first skim, I don't think many changes will be needed.
Hi, @HTenkanen I got a quick question. I was just going through some of the details on retrieving networks in pyrosm, btw, absolutely love the package, I was looking over some of the details on the network filter and the definition of a driving network. I noticed you and Geoff have basically the same filter system. I was wondering if there is any source that helps define which tags to choose for which situation or if there is any other way to get through the OSM tags more efficiently than going through them manually.
Hi all, I’ve drafted my proposal for the GSoC street network simplification project. If you could skim through it and let me know what you think before the submission deadline, that would be great!
Thanks! Can you put it on Google drive so we can comment on specific parts? I’m not sure how to efficiently review this otherwise
I meant Google docs of course…
@gsagostini_twitter I left just one minor comment, this read almost like a grant proposal. Good job, we'll have tough evaluation. And say hello to Trivik and Juliana if you'll speak with them :). Maybe @jGaboardi or @amorfinv have some further suggestions.
@ljwolf@sjsrey I found the name of the library I was missing (formulaic) and the technical term for the formulas in question (Wilkinson formulas). Here's an updated draft of the proposal -- let me know what you think!
(also paging @knaaptime because we've discussed this together!)
@thoffman1 the proposal looks great.

Yes, looks good @thoffman1! My one recommendation would be to put some specific dates on the phases, in order to provide an indicative schedule. They can totally be tentative, but they should be there!
wonderful! I added weeks according to the official timeline. Since it's planned to be a large size project (350 hours), I'm budgeting 16 weeks plus one week at the end to wrap up and present at the October 7 PySAL dev meeting. Thanks for the feedback!
Hey @martinfleis , Thank you for all these comments. I have made change according to your comments. Please look again the proposal and give me feedbacks. I am sorry for being in haste, but today is last day to submit proposal for GSOC. I hope you understand.
@martinfleis I’m just now seeing your “PySAL Effect” graphic for momepy download frequency. Very cool!
Hey folks! Hope you're well... In the long wait for the GSoC results to come out I decided to do some prep work and I wanted to ask you guys about two recommendations. (1) Can you think about a performant library for doing isochrons from multiple origins (5k+) ? More than the actual polygons I'm thinking to have the distance values directly on to a street network. My current thinking is to iterate through subgraphs and run a shortest path with no destination. But it sounds like there could be library already for that.
(2) if you wanted to start a new library...(say for indoor analysis ;) ) where would you recommend to start?
1) @knaaptime was cooking something :), 2) I'd recommend setting up infrastructure first, like CI etc and then start filling it with functions. You can even check the pysal template package but I am not sure if it is up to date and it has some pysal-specific tweaks like the docs buiding https://github.com/pysal/submodule_template
@gregmaya@knaaptime and I have been working on some isocrhones for a related project but haven’t yet figured out where to land it. Would be good to connect on future plans.

Hey folks, is there a calendar link for today's developer meeting?
