I have collected some temperature data from a Google Car dataset with each data having Lat/Lon and temperature values. The data is stored in CSV file. I already fixed the GPS lat/lon by using "project" and "interpolate" using this shapely Snap points. Snapped points

I also have a shapefile of the road the car took divided into 30 m segments.30 m segment of road

What I want to know, how can I snap/group GPS data to these 30 m segments in QGIS?

I am using QGIS 3.16 and all data is projected in ESPG 4326.

    Please don't post two questions at once. Also, I am under the impression, that both issues have been dealt with on GIS.SE already.

  • Hey sorry, I am not aware on what exactly to find. I am really new to GIS domain and also using QGIS. You have any reference/link that will be helpful? Feb 3 '21 at 10:25

After some searching, I realized that I can use "Join Attributes by Location (summary)" to calculate the some statistics for all the points lying on each 30 m line segment.

This answers my question.

But I have issue that I am not able to get values for all the line segments. The join only gives me statistics for few line segments.

  • You should not ask a question in an answer - it will go unnoticed. Rather ask a new question
