How to import csv (sample GPS). 

This is also helpful for making geological maps. Research papers in geology mostly have the geological map. But I do not usually find the file of the geological map. So we have to make the map from scratch which is not efficient. 

I made a geological map using QGIS which is very efficient and has many potentials. This is my memo. I hope this helps you somehow!


1. Sample CSV file

ex. 

column 1: sample name

column 2: X latitude (DD: decimal degrees  _ex. 2.27723)

column 3: Y longitude (DD: decimal degrees  _ex. -101.44623)













*It is also nice to add other columns (ex. depth, compositions, lithology)


2. Open Data Source Manager



3. Import sample data (GPS)

add the file (path) (ex. desktop/file/name.csv) in file name or we can also add the file from the upper right corner like below.


Open




Choose X(longtitude) and Y(latitude) and/or Z (depth etc) from the data file

Geometry CRS is how we project the data 
For example, I want to use the Robinson projection, so I chose World_Robinson CRS as shown in the image below.

1. go to coordinate reference system selector
2. filter: searching "Robinson"
3. Ok
4. Add





Then, the data should be in layers now.


If you cannot find the points, right-click and zoom to the point
