For the default coordinates, look at the "default_extent" field on the view definition, this field is the area on which the map is centered.

default_extent = fields.Char( 'Default map extent in 900913', size=128, default='-123164.85222423, 5574694.9538936, 1578017.6490538,' ' 6186191.1800898')


'-123164.85222423, 5574694.9538936, 1578017.6490538, 6186191.1800898', is the default extent which leads you to europe. It is the coordinates of a rectangle.



Once you have data, it should set the extent to match position of your data.

For zoom level this is not implemented in version 8 of the module, you can have a look at version 9 on how it was done.

Zoom by default is hardcoded, and when you have data zoom will fit your data.

Hi

actually, I use geoengine v-8.

When I add a map in the form, I always have the map centered in the 
center of the Europe.

My question is:

How can I decide the center point that I show in the form ?

Can I decide the zoom level too?


Thanks
