[MapProxy] Seeding using shape files

Tue Sep 8 08:15:21 PDT 2015

Hi all,

I have a doubt to seed a cache using shape files and I don't know if what I want to do is possible or not.

I explain myself...

I want to cache the flood areas of several countries using a shapefile which contains different polygons.
The shapefile to use would be similar to this. (Colors doesn't matter)

In this case, in the example above, each polygon represent a possible flood area.
What I want to do is to cache only the "areas" of the WMS service which are covered by a polygon.

I have tested two different configurations but I have obtained the same results.

*         Configuration 1

In this case I use a restricted shapefile with only two polygons.

However the summary of mapproxy-seed does not limited the area to cache to the two polygons. It cache all the bbox marked in red.

*         Configuration 2

The configuration number two, is similar to the previous one, but in this case, I have created the coverage areas using a where clause, selecting a specific polygon.

However the summary result is the same:

Is there any configuration that allows caching only the area covered by the polygons?

Thanks in advance.

Regards

Natalia
