Thanks. Nice video. I created a buffer for each centroid and would like to compare it to stations (points on another level). Especially, I would like to know which buffer have accessible stations within 3 kilometres. intersection

I have my tables set up in the same way to track networking among correspondents - but when I add the virtual layer no lines are showing up connecting the idfrom and idto.... I've been trying to troubleshoot this for a couple days now and am at a loss of what I have set up wrong.

Nice Tuto! Congrats! When I want to test the Virtual layer, I always have messages of syntax error, I triple check and I am sure all the text are equal. I am using QGIS 3.4. Do you think It can come from QGIS version?

Thank you so much! I have a question: suppose one also has a certain number of people staying within the city, and you'd like to visualize that. Is there a way to create arrow loops from one city to itself in QGIS as well?
@konradlawson29124 жыл бұрын
I haven't thought about that before. Of course, if you have exacts addresses of people, and you zoom in to the level of the city, those arrows could point from one person's address to another's just as set up in this video. However, if zoomed out, I am not sure it would be very clear without a lot of customisation for those specific arrows since the arrow heads would overlap and need fixing, but also the bend would need to be different for those local cases. I'm sure it could be done, but not sure how well it would as a visualisation.
@maxmuller1324 жыл бұрын
@@konradlawson2912 Hmmm alright, thank you for your thoughts. I'm now trying to do it by creating a set of copy set of points just next to the original ones. Then I proceed to create arrows between the original ones to the copies. In order to create the loops, it is indeed important to adjust the bend. I'm not entirely sure yet how to customize the bend in such a way that it is proportional to the distance between the points though. Or perhaps it's easier to manually adjust the bend for each pair, if one has a limited amount of nodes? If so, do you perhaps know how to manually adjust the bend of each arrow?

I have kept working on some of these base maps (e.g. merging South Asian countries for colonial India, merging central asian countries into Russia for Soviet Union, etc.). Eventually I'll share these sources for anyone who might want to use them in teaching.

Hi I have a problem, it is related to the distances query nearest I have 2 point layers A and B, layer A has fields ID & CODE ROAD, I want to find layer A' s points there are distances nearest with B layer 's points, and satisfies the condition there are CODE ROAD mentioned (that is, these points must be distance nearest with layer B 's points, and must be on road k) I hope to receive your idea, thanks many
