Goals

To get more and/or better quality landuse data, mostly natural and water related

Schedule

TBD

Import Data

Background

The Swedish parts of the EU Natura 2000

Data source site: Links in feed

Data license: metria.nu/miljodataportalen

Type of license : CC-0

ODbL Compliance verified: yes

Source data preview

OSM Data Files

TODO

Link to your source data files that you have prepared for the import - e.g. the .osm files you have derived from the data sources.

Import Type

TODO

Identify if this is a one-time or recurring import and whether you'll be doing it with automated scripts, etc.

Identify what method will be used for entering the imported data into the OSM database - e.g. API, JOSM, upload.py, etc.

Data Preparation

Data Reduction & Simplification

TODO

Describe your plans, if any, to reduce the amount of data you'll need to import.

Examples of this include removing information that is already contained in OSM or simplifying shapefiles.

Tagging Plans

FORANDRING ignore
KARTERINGS Review status: keep in transformation to aid in conflation (remove before upload?)
KOMMENTAR Comment: keep in transformation to aid in conflation (remove before upload?)
KOMPLEX Parent type (ie lake in bog or beach in islet): ignore
NATURTYP Class: base for transformation see table keep in transformation to aid in conflation (remove before upload?)

MALNATUR3 ignore
OBJECTID Id: ignore most features are going to be merged anyway
NATURTYPKO Class of parent type: ignore

Changeset Tags

TBD

Describe how you'll use changeset tags in the import.

Data Transformation

Parsing source shp files with ogr2osm todo put transformation script on git hub

Table with all used codes and their osm tags

Note that several codes are defined as uncertain in the source material and need to be classified be the user doing the conflation.

Data Transformation Results

First example draft (2017-04-07 end result is post-conflation)

Morevildmark only org2osm trasformation

bengtsfors only org2osm trasformation

Marstrandsfjorden only org2osm trasformation

Data Merge Workflow

Team Approach

TBD

Describe if you'll be doing this solo or as a team.

References

List all factors that will be evaluated in the import.

Use the official interpretations as guides for uncertain areas

English descriptions 

Swedish descriptions

Marina naturtyper 1110-1650

Skogar 9010-91F0

Gräsmarker 4010-6530, 8240

Våtmarker 7110-7320

Workflow

Detail the steps you'll take during the actual import.

Information to include:

  • Step by step instructions
  • Changeset size policy
  • Revert plans

Remember to open adjacent files when working near Län borders

There are no duplicates across the shp files so some large features are missing of you only use data from one file.

Note that the quality varies a lot from orthophoto (normal and IR) traced and field verified on the high end to ~30x30m resolution semiautomatic classified from aerial /satellite imagery on the low end.

Line data quality is good for position but poor for connectivity and direction, ie every way need verifying.

Select appropriate size data, inc any relations

copy (control + c) - new layer (control + n) - paste at source position (control + alt + v)

remove small areas, jsom filter
 areasize:0-150 closed
select all (control + a), unselect nodes (shift + u), delete

check fixme and comments, remove fixme when done

join adjacent areas with the same tags (shift + j)

merge in existing osm data

use replace geometry (control + shift + g) when replacing objects
