Geometry from WKT

Here’s a new issue related to importing WKT. It can be replicated as follows:

  1. Load the product: S1A_IW_SLC__1SDV_20151116T062645_20151116T062713_008626_00C402_43DC.zip.
  2. Open the intensity band of any subswath.
  3. Go to Vector -> Geometry from WKT and paste POLYGON ((-6.836904122773189 37.339906877047703,-6.974919869843501 37.240484037217094,-6.817678048554439 37.157348938725931,-6.588338448945064 37.275460891205142,-6.672795846406001 37.33062569180521,-6.836904122773189 37.339906877047703)). Click on OK.
  4. You’ll see the polygon is always drawn outside the image. There seems to be a shift in range.

Note: I’m using the latest version from git.

Before you can do this the product needs to be deburst.
Even then, the coordinates would be affected by the slant geometry.
In order to accurate place a vector given in lat lon, the product should be geocoded.

Thanks for replying Luis. I will do that then.
