how to export area in os map

Hi there,

I am using os map. I want to export my required place’s coordinates data, but it is giving me only rectangle to select the area.

But my required place is in eclipe, or something in polygon, how can I do this see the attached picture

I am looking forward to hearing from you soon.

Many thanks,
Rao

Not quite sure what is meant by “os map” (and pretty late to ask about the OP) but generally you can get arbitrary polygon extracts on https://extract.bbbike.org/ Once you moved the map to your area of interest and click on “here” the website starts with a rectangle. You can resize it, move it and add points to its contour. Available output formats include a variety from pure osm data to Garmin and Android compatible maps.
