<div> </div>
<div>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.</div>
<div> </div>
<div>It's possible and better to edit the geometry directly with the geometry tools.</div>
<div> </div>

<b>Betreff:</b> [Qgis-user] check for coordinates in an attribute table for shapefile layer</div>
<div name="quoted-content">Hi,<br/>
<br/>
I imported a .csv file with about 100 datasets and created a shapefile layer from the X and Y data.<br/>
<br/>
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.<br/>
<br/>
What I did no realize is that the data in X and Y will not be accepted automatically as geo coordinates.<br/>
<br/>
Now I have a map without the full set of points, and I do not know the following:<br/>
<br/>
1. How do I check quickly, which rows need ne geocoordinates from the X and Y columns?<br/>
<br/>
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.<br/>
<br/>
Thanks,<br/>
Maria<br/>
