I am trying to merge two polygon shapefiles in QGIS 2.6.1.
- One is older one with all state boundary, which I have (.shp, .shx, .prj, .dbf).
- New one is downloaded from WEOGEO (.shp, .shx, .prj, .dbf ) and Coordinate ref system EPSG:4326 - WGS 84 - both.
In the newly merged shapefile the Polygon overlaps. If I set the transparency to high layer below is visible.
I thought of editing attribute table but, both have different attribute fields.
- The old one have field like ID, NAME, TYPE, LENGTH, AREA.
- But the new one OSM_ID, BOUNDARY, NAME, ADMIN_LEVEL
I am new to QGIS, how can I get the area and length of new polygon if I have to match attribute field of old.
