Add DVW areas

[damianooldoni]

Based on useful discussion with @fjasteen, we have a better overview now about the shared areas to add for De Vlaamse Waterweg (DVW).

areas	tags
districts	DVW, district, one of: aZS, aBS, DS (departements, afdelingen)
sectors	DVW, sector, one of: aZS, aBS, DS, one of: core, extended
parcels within a sector	DVW, parcel, one of: aZS, aBS, DS (departement, afdelingen), one of: core, extended

Some details:

1. parcels are grouped per sector. So, we have a one-to-one replationship between parcels and sectors. If a user wants to have its own parcel, he/she will add it as a custom area.
2. almost all sectors with tag core have their sector counterparts with tag extended. Notice that these sectors share the same name. The use of tags kern/extended will guide the user to choose the right sector while maintaining the sector name short (no need to add "core" or "extended" in the sector name as prefix or suffix )

@fjasteen will send us:

1. shapefile with districts
2. shapefile with sectors defined as above. The shapefiles we have now are slightly different as the extended sectors are areas without core. They are complementary to the core sectors. We found such sectors not useful from a user point of view. The extended sectors Frédérique will send us soon will contain their core counterparts.
3. shapefiles with parcels per sector. See details in point 1 above. At the moment, we have an example of the parcels but they are not aggregated at sector level.

All DVW_geodata files are within this Google Drive folder .

1. Districts: the shapefile containing the districts polygons
2. Sector_core: the 'Kern'-areas within each sector
3. Sector_extended: the whole of the area of the sector, the 'kern'- or core- areas included
4. Sector_parcels: for each sector a multipolygon of all of the contained parcels

Thanks @fjasteen for the shapefiles provided in the link above: very well done 👍 @niconoe: here below a practical table of what to import and which labels to assign:

Districts

The districts are contained in the shapefile in folder Districts. It's a one layer file containing 17 multipolygons.

area name	tags
values in column DSTRCT	DVW, district, value in column AFD, i.e. one of: aZS, aBS, DS

Sectors

We have two directories containing core sectors and extended sectors

Core sectors

The core sectors are contained in the shapefile in folder Sector_core. It's a one layer file containing 48 multipolygons.

area name	tags
values in column SCTR	DVW, sector, core (also contained in column TYPE), value in column AFD, i.e. one of: aZS, aBS, DS

Extended sectors

The extended sectors are contained in the shapefile in folder Sector_extended. It's a one layer file containing 48 multipolygons.

area name	tags
values in column SCTR	DVW, sector, extended (also contained in column TYPE), value in column AFD, i.e. one of: aZS, aBS, DS

Sector parcels

The sector parcels are contained in the shapefile in folder Sector_parcels. It's a one layer file containing 33 multipolygons.

area name	tags
values in column SCTR	DVW, parcel (column TYPE = "parcels", but singular is preferrable), value in column AFD, i.e. one of: aZS, aBS, DS

Thanks @damianooldoni.

The areas have been imported to dev, can you have a look?

[damianooldoni]

Hi @niconoe: it looks nice. Thanks!

Only one thing: when selecting tag aBS I get also all areas with tag DS or AZS. These tags are department related and therefore should be mutually exclusive: ONE OF rule.

[niconoe]

Indeed, that's a distraction bug :) Fixing it now!

[niconoe]

It should be better now, can you recheck?

[damianooldoni]

Great job!

[fjasteen]

Looks very nice! Thanks a lot!
