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
