Hi everyone,
I am experiencing some trouble publishing polygon layers as I realized that the WFS service, apparently, simplify my features. And, as we are dealing with property limits, this simplification cannot occur.
I am using version 2.16 of Geoserver, store type is POSTGIS, and the option ‘Support on the fly geometry simplification’ in the Store configuration is unchecked.
Would any of you know how I can solve this problem, and present the WFS according to the existing geometry of my database?
**Link of the service:**http://geovis.dev.planejamento.gov.br/vetor/spunet/ows?version=1.0.0&layer=spunet%3Aareas_uniao
Abaixo, segue print da apresentação da mesma camada em WMS(cinza) e WFS(verde-simplificada).
Below is a print of the presentation of the same layer in WMS (gray-like database) and WFS (green-simplified).

Strange, I'm not aware that anybody will automagically simplify stuff.
Even loading both layers in epsg:4674 I still get different data.
Are we 100% sure it is exact the same data?
Because even holes in polygons (like 4 coordinates, so NON simplified) seem to have other coordinates (see screenie).
Regards,
Richard Duivenvoorde

Hi Jessica,
GeoServer WFS has no actual “geometry simplification” option. However, there is a setting that acts
as a simplifier of sorts: the number of decimals used to represent ordinates.
Typically 6 is enough for data in geographic coordinates, did you set it to a smaller value?
The effect is to basically snap every point to a grid (it always is, but becomes visible if the
number of decimals is small).
Cheers
Andrea

Hi Andrea,
The setting of the max number decimal was set indeed at “0”!!! Changed it to It worked!!!
