Some proportional symbols are outside the boundaries

Good morning/afternoon,
When we represent Proportional symbol map, we noticed that some symbols are represented outside the boundaries of the country - specially for countries with irregular shapes or country consists of multiple polygons (like USE symbol lies on France).

Is the symbol lies on the center point from the shape file or is StatPlanet use special methodology? How we can set the position of these symbol s?

Hi,
StatPlanet centres the symbol in the exact middle of the shape. For the world map edition, however, some special adjustments were made to improve shape positioning for countries with unusual shapes. For shapefile maps, the only option is currently to have them appear in the middle of the shape. If you would be able to share a link to the map or the files via e-mail, it could be looked at to verify if anything unusual is happening with the symbol positioning.

Dear Frank,
I sent email to you.
Best Regards.

Many thanks for sharing this file. I can see now what is happening. It seems that one or several pacific islands administered by the USA might be included as part of the USA shape within the shapefile, so when the symbol goes in the middle it is between the USA shape and the pacific island shape. There could be two options to resolve this:

(i) Edit the shapefile map to remove the pacific island (or whichever shapes are causing this) associated with USA, and similarly for any other potential territories where this could be causing the symbol to appear in the incorrect position.
(ii) Purchase the world map edition, where the symbols are correctly placed (see also www.statsilk.com/maps/world-stats-open-data).

If you need more details just let me know.

Dear Frank,
Many thanks for your support, but we have to use Shapefile map edition because we have other Shapefiles for UAE and Abu Dhabi Emirate with different geographical boundaries like districts and sectors.
Instead of removing pacific shapes are causing this, can we let our GIS team to move the center point in the shapefile to be in the desired place? Do you think this can solve the problem?

Dear Tarek,
You could use both editions, the world map just for your world map data and the shapefile map for the ones that require shapefiles. Sorry I am not aware of a way to change the center point of a shape. Instead of removing a shape, it could perhaps also be 'counter balanced' by inserting a tiny dot/circle (which isn't visible) on the other side, e.g. for the USA map put a tiny circle on the other side at the same distance as the pacific island. Then the centre point would once again be USA. Otherwise just using the world map edition for this particular data set could resolve it, if you do not have the problem with your other maps.

Best,

Frank
