I am using QGIS V 3.2 and I need to create an area to form a polygon shapefile using a latitude and a longitude, not using python as I am just a beginner. Does anyone know how to do this?

To give an example according to @geom recommendation. You must use the syntax to define polygons in WKT format, here an example in CSV:

Finally use add delimited text data source:

With the following result:

To edit the question to provide an example of where I need to create a polygon via distances.

I need to create a polygon to represent a survey area. The survey area required is 3.58km x 3.0km. I have used the v.buffer GRASS tool and the Buffer tool. Which I select a certain point to buffer Around to create the survey area. However I cant find any input within these tools where I can enter such distances. Do you know how to fix this?

  • perfect, thank you for providing an example. Would I follow the same formula if I wanted a polygon with specific dimensions rather than coordinates. e.g length in km. – Bodhi Nov 21 '18 at 14:16
  • Could @Bodhi provide some example, some data to provide what you require? I think it's best to do the coordinate calculations from the dimensions in the spreadsheet and then perform their representation in QGIS. – SamTux Nov 21 '18 at 16:17
  • sure, Provided an example in the problem – Bodhi Nov 26 '18 at 9:34
