I have a huge point file (4933873 points, currently in GeoPackage)) looking this way:
imported from a CSV of following structure:
Captured Time,Latitude,Longitude,Value,Unit,Location Name,Device ID,MD5Sum,Height,Surface,Radiation,Uploaded Time,Loader ID 2016-11-04 01:00:07,37.4932,139.93305,38,cpm,,101,e40768be06169b47c412cdbc8b50ee51,,,,2016-11-04 01:00:07.805856, 2016-11-04 01:00:03,37.366713,140.53097,27,celcius,,100079,0654275d9d656aac8f1ee06eaf2ca8d0,462,,,2016-11-04 01:00:03.691745, 2016-11-04 01:00:02,37.366713,140.53097,11,cpm,,100072,b48a5a4b821d04d2071d233d99fc9bf5,462,,,2016-11-04 01:00:03.149019, 2016-11-04 01:00:01,37.366713,140.53097,56,cpm,,100071,654c26d9ad16aa776613db4913a6ee95,462,,,2016-11-04 01:00:01.932265,
And I need to remove those orange / red straight lines (airborne data) and keep the rest (ground measured data - car/walk etc.). Unfortunately there is no altitude so I cannot easily filter it out.
Is there any better way to select consecutive points (after selecting one to begin) without need to load attribute table for a whole layer?
