I want to create an ellipse around a point. I have the lat/longs of the point and the length of semimajor and semi minor axes in a CSV format. Is there a way?
An example csv
Geometry by expression
Expression (in the step-3 above):
make_ellipse(transform(make_point("lon_dd","lat_dd"), 'EPSG:4326', 'EPSG:32653'), "semimajor", "semiminor", "az")
QGIS (< 3.0) ... (Tested in QGIS 2.18.19 on Windows10)
Shape Tools Plugin
This time you need to (1)
Add Delimited Text your csv on WGS84 (EPSG:4326) (2) reproject the point by
Save As, and (3) set the project CRS to fit with the reprojected point data.
Then, using Shape Tools
The output image is the same.
