I've a list of coordinates which were recorded in a last years aerial survey. Besides this I've the flightlog. The list of coordinates was created "manually" by writing down the position into a spreadsheet.
The projection of the flightlog data is: WGS84, EPSG4326
This files works fine and the locations seem to be correct.
Now I'd like to create a point-shapefile from my excel-spreadsheet. The problem right now, is that I don't have any information of the used projection. When I try to use EPSG4326 I get a gap (see screenshot).
The coordinates are as follows:
S074233 E0341051
S074109 E0340115
S073729 E0340115
S071631 E0342037
S071628 E0342837
S071409 E0343446
S071525 E0343546
I'm a bit perplex. Maybe important to know that they maybe used Skydemon or Garmin as GPS recorder. The area of interest is in Tanzania. I've access to ArcGIS and QGIS.
