I am fairly new to QGIS. I am attempting to import a CSV file with lat/long coordinates into a project I have been working on. Each time I import the file, I receive an error stating my geometry is invalid. I did some research, and found that as I am working on a mac, it was important to save the file as a windows formatted CSV. This has not helped. I also tried separating the columns such that the lat/longs were formatted differently, and did not include letters. This has also not worked either. I've tried to upload some images but unfortunatly i have very poor internet in the area in which I work. Can anyone help me out here?

QGIS Add Delimited Text Layer can handle either DD (decimal degrees) or DMS (degrees minutes seconds). But unfortunately your data is formatted in degrees plus decimal minutes (sometimes called DM). Please change the format to decimal degrees and try loading the data again.

If you don't mind using MS-Excel the conversion can be done like below. enter image description here

A2: N 0 27.888
B2: E 30 18.648
C2: =VALUE(MID(B2, FIND(" ", B2)+1, 2))
D2: =VALUE(MID(B2, FIND(".", B2)-2, 6))
E2: =VALUE(MID(A2, FIND(" ", A2)+1, 2))
F2: =VALUE(MID(A2, FIND(".", A2)-2, 6))
G2: =C2+D2/60
H2: =E2+F2/60

EDIT ...... if Southern (S) or Western (W) coordinates are included:

G2: =IF(LEFT(B2,1)="W", -1 * (C2+D2/60), C2+D2/60)
H2: =IF(LEFT(A2,1)="S", -1 * (E2+F2/60), E2+F2/60)

Once calculation is done, save the sheet as csv and load the data to QGIS using X, Y (columns G and H respectively).

    There might be some tweaking necessary for West and South coordinates. The result must be negative, and the minutes subtracted instead of added to the degrees (even for zero degrees). – AndreJ May 29 '17 at 15:04

    uh-oh... get to it right away. – Kazuhito May 29 '17 at 15:27
