WikiProject Lithuania/Import Public Document

Rietavo municipality

This is short description of public document import process.

Data

Data available at http://www.rietavas.lt/index.php?113113998. There is folders with shapefiles and ADF files.

Software

QGIS for loading vector files and changing projection
GRASS for converting from shapefile to GPX
Merkaartor for conversion from GPX to GPX (some bug: cannot convert to osm format or load directly)
JOSM for loading GPX, converting into data, resolving conflicts, adding tags

Basic steps

Load, merge and reproject shapefiles
Load shapefiles with grass and export to GPX format

   v.generalize input=test output=test_generalized method=douglas_reduction threshold=0 reduction=50 -c
   v.out.ogr --verbose input=test_generalized@PERMANENT type=line dsn=test.gpx format=GPX

Load GPX with Merkaartor and export to GPX (without this conversion you will get only points without vectors)
Load GPX file with JOSM and convert into data layer
Add tags (very important is source=public_document), check validity and resolve conflicts
Upload
