Normally yes, but it seems I have overdone it here a bit.
Do you know which one is the vegetable oil mill, so i can revert that one?
Feel free to change it yourself if you like.

Hi crisitunity,
why did you remove the landuse and industrial tags for the substation areas?

Well, there are 4 gas (see below) and 1 oil pipelines in the area. For me it was not "clearly" the substation for an oil pipeline. But rather the opposite, since the only pipeline that has a node inside the substation is a gas pipeline.

Anyway, if you have information/knowledge that this is for an oil pipeline, feel free to change it to industrial=oil, I'm fine with that. (Maybe add a node for the oil pipeline inside the area as well.)

gas pipelines nearby / inside:

Well ... I added a waterway ... to the relation.

You can also see it in josm relation history.

They are not meant as a category, after all they are connected to each other.
Put all ways in 1 giant relation would cause problems. There needs to be seperate relations for each section, yet also one which contains all parts.

Hi surveyor54,
I basically "connected the dots".
The start and end/connection points were already existing areas.
I've included already existing pipeline sections where they were available and reasonybly obvious to be a part of the pipeline.
The course of the pipelines in/under the ground is not as straight as currently mapped, but i have no detailed course data available.
I'm happy to split long sections into smaller ones where markers or pipeling substations are available (mapped).

Hi,
yes the pipeline is not visible, but the start- and end/connection points are visible. At least the big ones.
The layer tag was indeed missing on some lines. I've added it together with location=underground for the pipelines where it was missing. Thanks for pointing it out!

I've added lines between the already existing connection points. The exact course is unknown to me, therefore they contain the note "location estimated / interpolated", location meaning the course here.

Hi geow, die areas waren größtenteils schon vorhanden, ich habe die halt zu einem MP zusammengefasst.
Besondere Datenquelle habe ich keine, nur das Sattelitenbild (war eher Bayern 80cm statt bing wie im source steht).
Auswahl welche areas dazugehören? Die haben alle ein spezielles, ähnliches aussehen auf dem Bild, landuse=industrial und keine buildings (außer Hauptgelände).

Hi geow, der Link war schon da, ich habe leider keinen besseren.
Den Namen habe ich nicht geändert, da ich zum Status nichts sagen kann (ob z.B. Bau schon fertig oder nicht).
Ich habe das nur anhand des aktuellen Bildes angepasst.
Wer näheres weiß zum Namen oder Status, darf das gerne anpassen.

Ja stimmt, der ist aber nicht von mir.
Der ist vom ursprünglichem landuse und wurde beim Umwandeln in multipoly automatisch übernommen.
