Re: [Qgis-user] check for coordinates in an attribute table for shapefile layer

[geo . guide]

Dear Maria,

 

if you export your shapefile to csv and reimport it in QGIS with your X and Y values as the valid coordinates again, your problem should be solved.

 

It's possible and better to edit the geometry directly with the geometry tools.

 

Regards, Christine

Betreff: [Qgis-user] check for coordinates in an attribute table for shapefile layer

Hi,

I imported a .csv file with about 100 datasets and created a shapefile layer from the X and Y data.

Then I did something stupid. I deleted some duplicates and changed the X and Y data slightly in three or four data sets, and I created a new row with one new data point and X and Y data.

What I did no realize is that the data in X and Y will not be accepted automatically as geo coordinates.

Now I have a map without the full set of points, and I do not know the following:

1. How do I check quickly, which rows need ne geocoordinates from the X and Y columns?

2. When I figured which data set need updates, how do get the X and Y data into their geocoordinates and get them shown on the map.

Thanks,
Maria
