[Croatia] Reviewing osmlint-osmium and osmlint data issues

[sbelemey]

Background

As part of on-going work to improve the quality of OpenStreetMap data, we use internal Mapbox data validation jobs that search OSM data for errors for detecting issues related to road network data in Croatia. In total, we are going to review issues in 7 categories.

Our plan is to review all detected issues and fix it in OpenStreetMap. There's a link to the OSM Wiki page.

Timeframe

We are going to start review in the end of April 2022.

Tools

We will use existing OpenStreetMap editing tools, we will use #hashtag for the project #mapbox_linters_croatia

Editor: iD
Satellite Imagery: dgu.hr: Croatia 2019-2020 aerial imagery, osm-hr: Zagreb 2018 Aerial imagery, Bing, Maxar, Esri

Hi! Thanks for your work.

I'm trying to review these using geojson.io, however I'm running into errors. Upon inspecting the provided geojson files I noticed that the root FeatureCollection object contains a list of other FeatureCollection objects (which in turn contain Feature objects). This is not valid according to RFC 7946.

A FeatureCollection object has a member with the name "features". The value of "features" is a JSON array. Each element of the array is a Feature object as defined above.

If you could provide valid geojson files that would be great.

Hi @ihabunek,
I flattened 2nd level FeatureCollection to match RFC and removed empty properties for top level FeatureCollection.
Please take a look.
