OpenAtlas

I found some issues with the kataster.bev.gv.at, which needs to be discussed:

Landing site¶

There is no nice landing site URL like with wikidata, geonames or GND. The URL, e.g. https://kataster.bev.gv.at/#/center/13.64543,47.55562/zoom/20.6/vermv/0.6 consits of a point y,y, the zoom level and some transparency. The only thing we could to, to link to the correct place is to calculate the centerpoint.
Or it is linked to its JSON representation.

Search¶

There is no fuzzy search, only an exact match search. This means one has to enter the exact Katestralgemeindenummer (kdnr), e.g. 42007, and the correct Grundstücksnummer (gnr), e.g. 222, and either there is only one match, or the sub parcel number are shown. So a valid search string looks like this: 42007-222

There is the possibility of adress search, but this gives no information about the kdnr or the gnr.

There is also no possiblity to list all Grundstücke of a Katestralgemeinde , so a system wide import of for example all Grundstücke of Hallstatt is not possible.

Questions¶

• Is there any official list of all Grundstücksnummer for a Katestralgemeinde?
• How are the students getting their information about the Grundstücksnummer? Also through kataster.bev.gv.at?

Swagger: https://kataster.bev.gv.at/at.gv.bev.kataster/api/swagger.yml or via kataster.bev.gv.at -> Anleitung/Guide -> API

tl;dr: So the implementation of a external reference system is possible, but the comfort functions like a fuzzy search and the link to a user friendly landing page will be an issue.
