I'm trying to map data for a county in Texas. The data were provided to me in a shapefile, and I've been working with it in QGIS 2.14. My problem is this: The coordinates in the shapefile I was given are wrong. The latitudes should all be in the 31-degrees range, but instead they're around 21 degrees N, which - when exported into Google Earth - puts the county squarely in Mexico.
Is there a way in QGIS that I can simply add ten degrees to all the inaccurate latitude coordinates? Everything else about the shapefile seems correct - it's just the degrees latitude are ten degrees lower than they should be.
