QGIS Tutorial: Network Analysis (Shortest Path/Route and Service Area)

[@musahasen5435]

I am investigating the effects of newly constructed rural roads by constructing a least-cost path between villages and the nearest available road. Hence, I have to construct the least-cost paths between many points (the number of villages is 1584) and lines (nearest road). However, most of the tutorials are for only two points (one starting and one destination point). Do you have another video that discusses the implementation of the least-cost path between more than one starting and destination point?

[@catherinezettner7581]

I have a similar issue, where I want to find the distance between many different points (houses) and many different, but 1:1 associated points (places of work associated with each house). Have you or anyone reading this had any luck?

[@giovanymontero766]

It would be a lot better without the loud music, but thanks, it's really good

[@giovanymontero766]

Forget it, you solve all my problems, and also at the end I thought the music was good.

[@catherinezettner7581]

Maybe you can find a tutorial on how to turn down the volume ;P

Hi, is it possible to make a route for door to door waste collection? I would like to build a route with multistops and where the start point is the same as the end point.

[@sowelhadjidemba2524]

hello @Matteo, i'm working on a similary project, could you please tell me if you found some tutorial on that subject? it seems there is not a lot of documentation about it.

[@matteoruggieri805]

Hi @@sowelhadjidemba2524 , unfortunately I have not found much material about it. I only have several options to start from, but I don't have any guide available. Could you please contact me in private? we could talk about this and maybe understand something more by joining our forces :)

[@nathaliasouza6169]

I wanted to find something like that too

Hello iam doing same project where iam doing solid waste management and route optimization using gis can you help me with any tutorial video on route optimization using gis step by step ​@@sowelhadjidemba2524

in 5:13 what it show,i mean from output .

[@fajaralim365]

quick tip: sebenarnya ada cara untuk mengubah node 5:12 hasil analisis menjadi poligon

[@MariSpasialkan]

Wah, mantap gan, sejauh ini kalau Saya pakai tool Convex hull, semacam bikin klaster polygon. Kalau Ente pakai apa/gimana gan biasanya, mungkin bisa dishare di sini..

[@afifurahman650]

kalau boleh, share dong caranya untuk mengubah hasil service area mencari polygon mas

[@MariSpasialkan]

@@afifurahman650 kalau yg Saya tahu untuk mengubah boundary nodes (hasil dari service area) menjadi polygon pakai tool Convex hull (di menu "Vector" > "Geoprocessing Tools" > "Convex Hull"). Silakan dicoba..

makasi jawaban nya mas,

sir how can I put turn restrictions like right turn, left turn and u turn restriction in network analysis in qgis

[@علاءالدينكمبو-ظ9و]

I have a question, can the program Arc Gis analyze the road network and exactly determine the shortest path from point 1 to 2, and from 1 to 3 and from 1 to 4 that is, making several paths from one location to several points, and how is this done if I have one center and 12 thousand Point

[@michaelspector92]

I can't see the plugin. How can I install it ?

[@MariSpasialkan]

In QGIS2 you can use Road Graph plugin ( 0:14 ), but in QGIS3 you can use Network Analyst tool ( 3:30 )

[@amritsingh4095]

Sir I am unable to find network analysis plugin in qgis software. Can you please tell me which version of software you are using.

I'm very new in this ,can you please help me with network build ....I have points and line shape file with me but unable to generate network.... please help

[@meinartysinurat4412]

Mas pakai shortest path ini Kan udah nemu jalur nya. Terus kalau mau jalur nya diubah jadi ke kalimat Arah rute. Gimana ya mas? Apa Ada Cara konversi ato apa gitu. Hehe

My Road Graph plugin is missing then how to do?

[@MariSpasialkan]

Try reinstall the plugin

Mas, data atribut tabel di service area isinya apa?

[@MariSpasialkan]

maksudnya atribut table dari layer hasil proses service area? kurang lebih sama dengan atribut data titiknya, cuma ada tambahan field type dan start

[@ing.3291]

How can I calculate the longest path?

[@MariSpasialkan]

you can sort on "cost" field from the shortest path analysis result layer

[@ing.3291]

@@MariSpasialkan Thanks for the answer. But do I have to sort according to the field "cost" from the table of attributes of the shape "shorter path" generated? Because then I have no choice.

[@muhammadnoorhafizimohammad9406]

@@MariSpasialkan what unit for the "cost"? meter or what?

[@RomyAulia]

bg itu bisa dijadikan webgis ga bg?di export ke qgis2web?

[@MariSpasialkan]

layer output dari network analisisnya yak? bisa aja kalau mau ditampilkan di webgis pakai qgis2web ..
