Re: [Qgis-user] Isochrones

[Tyler Veinot]

All;
It isn't the networ because the tool works fine when I interpolate the
results as points instead of a raster.
I think it is in how it bulbs the tin, I will have to do more checking.
Thanks;
Tyler

Nicolas is right. There is  good chance the topology is a bit messed up. You 
can spend Lot of time fixing it up so I would suggest downloading the gis 
basmap layers from the pei government website. There us a large scale database 
for Charlottetown  (1:2000) that will work better for you. Just search gis 
database pei.KirkSent from my Samsung Galaxy smartphone.

Hi Tyler,

I have step-by-step tutorials for using the built-in network analysis
tools, QNEAT3 and ORS Tools plugins that show how to setup and use them. Do
have a look and see if you can make it work for your dataset.

*Basic Network Visualization and Routing (QGIS3)*

*Locating Nearest Facility with Origin-Destination Matrix (QGIS3)*

*Service Area Analysis using Openrouteservice (QGIS3)*

Re: [Qgis-user] Isochrones

[Nicolas Cadieux]

Hi,

The first thing I would do is to check the network integrity.  Perhaps some 
road are not connected (snapped).  You also need a snap and break at every 
intersection. You can do some of this by exporting all the end node. Check for 
multiline vs lines. You can split all of those in the vector menu.  Your 
problems are likely linked to a bad network topology. Users of that network 
could perhaps confirm this? I have used it but not for this type of stuff.

All;
I have a network, Canada National Road Network it is a free download, that
I am trying to use for PEI and the City of Charlottetown to find out what
area is within X time of various points of interest. I used Here for QGIS
to get the initial result but QGIS has a tool built in Network Analyst that
has Service Area from Network and from Point, also and QNEAT that has 6
isochrone tools for doing exactly what I am trying to do. For some reason
though the results don't seem to match the network. I would expect the from
the point of origin the shortest times to be along the lines and radiate
out.
What tools are you guys using to do this kind of work? Do my values for
forward backward both direction need to be numeric? Any tutorials on using
these tools?

[Qgis-user] Style Manager not Showing Anything in items to Import

[Tim Smith]

Hi All


Please could somebody help.  I am using QGIS 3.10.3 on Linux Mint 19.3.
 I am trying to add styles from an xml file.  I did this with no
problem using this xml file in previous QGIS versions but when I try to
do this in QGIS 3.10.3 the Select Items to Import is blank and does not
contain anything so I cannot select anything!   Very grateful if
anybody can help, thank you.


Kind regards

[Qgis-user] data defined override dash pattern

[lars lingner]

Hello,

I'm styling a polygon feature with "Outline: Simple line" and using a
data defined attribute for custom dash pattern.
As long as the the data defined override is set, the enable/disable
checkbox "Use custom dash pattern" doesn't have an effect.
It seems it is always enabled.

I have to clear the override to use the stroke style setting again.

I would have assumed, if I disable the checkbox, the custom dash pattern
isn't used anymore.

Is this known or somehow expected? Should I open a issue about it?

QGIS version 3.10.4-A Coruña
QGIS code revision 10bc9f2ff2


Best wishes,

Lars
