I have been given a CSV file which contains the Longitude and Latitude data points for a number of mobiles that run our own internal app. The data includes the unique
"ID" for the device plus a date & time stamp for each ping received.
I have been asked if I can extract the data to show only the mobiles within a specific area. I'm new to this so based on research I think I need to create polygon covering the area we are interested in and then work out which points are within that polygon.
I have downloaded and installed some software called QGIS which seems like its capable of doing what I need. I have imported the CSV file which looks correct.
Can anyone point me in the direction of how to go about getting the info i need. Ultimately I wanted to extract the points I'm interested in and then load that into kepler.gl to have a graphical view of the movements over a period of a week so I need to retain the unique
"ID" and date / time stamp but for only the points within my polygon.
