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
