Re: [datameet] Query regarding Heat map Generation

[Ujaval Gandhi]

Hi Jagades,

There are many ways to do it. Here are some ways to achieve this in QGIS

Easiest would be to use the GPX tracks (lines). QGIS has a tool 'Line
Density' in Processing Toolbox that will give you a heatmap based on
overlapping line segments. If you just have points with timestamps and
track id, use the 'Points to Path' tool to create tracks.

A more complex but accurate way would be to first snap your GPS points to
the road segments. I outline the process here
https://spatialthoughts.com/2020/02/22/snap-to-roads-qgis-and-osrm/ . If
you don't care much about accuracy, you can use 'Snap Geometries to Layer'
tool in QGIS and snap each GPS point to the nearest road segment. Then you
can do a spatial join 'Join Attributes by Location (summary)' and count the
number of points on each segment. Then you can use apply a symbology using
the 'count' field for each line segment.

I can think of 5 other ways, but instead of listing them here, I'll point
you to this thread which has more ideas :)

[datameet] Query regarding Heat map Generation

[Jagades Vignesvar]

Dear All,
I have a set of GPS Points (in both .gpx and .csv format), and the base
road layers in .shp format. Can anybody help how to generate a Line Heat
Map based on the available GPS points? (Like a larger number of GPS points
on a particular route indicates its being used frequently)
Thanks in advance.

Re: [datameet] Re: Ground water level map of India

[sonia agnihotri]

Hi Arun,
I tried this as well, it will point to the same page that I mentioned
earlier. 1st link to India_WRIS portal, 2nd link not opening for me and the
other two links provide pdf reports state wise not point or well level
information. Actually, I need well level information district wise so that
I can interpolate and prepare a water level map.

Re: [datameet] Discord

Agreed.
A slack or discord channel will be good.
Mainly as they may support better code sharing.
