Shortest & Fastest Routes, Isochrone Maps, Time - Distance Matrix using QGIS

[@nahrafdhom]

Best QGIS video I have seen. Point to point, explained each step.

[@MrFerMath]

As usual, quality tutorial. Straight to the point and very well explained. Thanks a lot.

Feature ID None caused a ApiError: 401 ({ "error": "Authorization field missing" }) This appears in my log after I clicked run for isochrone. What should I do to fix it?

[@harurindo]

Really useful and glad to see you demonstrate this on the latest version of QGIS. An explanation on the API key and how to apply that to the ORS tools would have helped too. I was stumped on that for a while as I added they key to the wrong place.

[@outbackaerialimagery171]

This is fantastic. The matrix option will be perfect for my thesis topic. Im going to use it to determine the shortest path from maintenacne roads (centroid) to water points and gravel stockpile points.

[@budd2460]

Really useful. Really simple. Thanks so much!!

[@kninja995]

am having this error when trying to run the isochrones " Feature ID None caused a InvalidKey: 403 ({ "error": "Quota exceeded" })"

[@adamuel-oji3510]

Thanks for the tutorials. My challenge is that I keep receiving error message run directions tool. Message is : The files are not supported for this algorithm What is the issue? Thanks

[@kashicumasankar5338]

Thank you so much for this! I could generate the path of a bus route by uploading the stops in sequence. But I got a spreadsheet with 200+ bus routes and their corresponding stops listed in sequence. I cannot generate directions for more than one route at a time. Please let me know if it's possible to create multiple paths at a go, and if so, how?

[@alqu2222]

Thanks for the informative tutorial. I have a question. What if I have my own network of roads which is in the desert and I need to calculate the driving areas from a point feature class over this network of desert roads? these roads are not available in the builtin data set as you demonstrated in the tutorial.

[@NalinBalasuriya]

Thank you very much for this tutorial

[@dr.mohanvasave3050]

excellent hands on tanning sir

[@milosuricic6860]

Great - simple explaination and very useful! Cheers! One question: what is the adopted average speed of movement of the cyclist and is it somehow taken into account the slope of the terrain? Thanks

[@randomsurfer007]

Thanks for the very useful video. Can you please demonstrate the travelling salesman problem using the matrix you generated?

[@TOMMYTOM1993]

How would you create isochrones using ORS for public transportation?

[@cityrise]

What if instead of using the OSM map to use as routes, I want to use a road segment shapefile? Especially if I'm working in places that don't have roads and I want to create my own road network and use this tool to test its efficacy?

[@Jiraporn_Vlog]

Hi, please let me know, What is the speed of the car in the Distance Matrix. How this function calculate ?

[@mcm018]

you saved me! thank you

[@jinglu7643]

Hi thanks for your tutorial very useful. I have a question regarding to the fastest routes that if the waiting at traffic light time was calculated or considered? Thanks a lot

Can matrix layer converted into a line (vector layer) ?

Thank you very much.

Hey how did you create those files in the browser field please? :)

[@Mariana-uf9it]

I have lots of points, I'd like to calculate the distance from these points to a street (layer). How to solve? It doesn't works

[@ssafal1634]

Is this your own voice? If yes, how do u get such crystal clear audio on these videos?

[@geodeltalabs]

Using a dynamic microphone can be immensely helpful for that :)

[@ssafal1634]

[@n.o.n.academic]

What are the features of the map you use? What kind of data should I have to make these calculations?

[@matteoruggieri805]

hi, I was wondering...is it possible to create a route for a garbage truck with qgis?

[@geodeltalabs]

Hi, can you elaborate a bit more on this.

[@matteoruggieri805]

@@geodeltalabs I would like to plan a route for two or more vehicles with multiple stops for waste collection. Someone said that this type of problem is called the Chinese Postman Problem and I don't know if its possible to solve it with this or other tools via Qgis. Anyway I just want to optimize and scheduling a route for this type of vehicles.

[@liciab7277]

is there a way to upload data from an excel sheet with starting and ending points and make a matrix from those? rather than clicking spots on the map?

[@geodeltalabs]

If you have the lat, lon then yes kzbin.info/www/bejne/jpjMXoiarqmcZ80

@@geodeltalabs Hello, I tried using the Matrix in ORS tools because I already have the data. But when I input the layer on the paramters and run, the log says "KeyError: INPUT_AVOID_FEATURES" What does it mean?

[@amyhowardmiller8328]

@@ravenalice8253 Did you go get your free API key from the Open Source?

[@onkarchothe6897]

Respected sir, I had used ORS tool to create Isochrones. I had to click on "Isochrones from point". and I had click "Run" button after filling in all information. But no any isochrones visible --- there the shapefile layer is created on the left side but Isochrones are not visible. Can you please tell me the correct way to create isochrones? . or Any settings?

[@ravenalice8253]

Maybe you can check log if there is an error

[@youssefm8983]

When i try to run the fastest or shortest path I get error. "Feature could not be written to Output_Layer_5f74ef56_a8d5_4d5c_a96c_6c2be63bfe78: Could not store attribute "id": Value "" is not a number " Any suggestion? Thank you.

Interesting facts

[@ing.3291]

How can I calculate the longest path?

[@geodeltalabs]

Hi, can you elaborate your intended application of that? Because in a practical sense, one can make the path as long as they want by taking detours further away from the intended destination.

[@ing.3291]

@@geodeltalabs Thanks for the answer. In my case, I have an open network and want to determine the longest route starting from one or two starting points.

[@ing.3291]

I have a hydrographic network and I want to determine the longest route from an initial point.

[@geodeltalabs]

Are you referring to the longest flow path in a hydrological sense? If yes, the techniques explained in this tutorial are not applicable as this is only valid for road networks.

[@ing.3291]

@@geodeltalabs Yes, I’m referring to the longest route in the hydrological sense. I was actually hoping that you would know a plugin or qgis function that could do this. Thanks for your time
