Hey,

I am new here, and i am new with arcMap.
I created a Mosaic raster dataset. (Digital elevation model, 90m resolution). I would like to add some datapoints from a .csv sheet.
(Longitude and Latitude, ca. 100 000 points).
my problem is, the points are all on a different scale (they look like 1 point, if i zoom in then they differ)

Dose some one now where the problem is?
Here the Screenshots to give a better look.

Thx

Hi Floelae,

This looks like a projection issue.  What projection & Datum is the DEM using?  You need to try and match the two datasets.  Are you using Lat/Long data to add your points from the csv file?  If so you may need to define the projection information when adding them.

I'm no expert on projections because I don't have to deal with them very often.

But perhaps this helps and gets you on the right track.  I'm sure someone else could chime in and be of more assistance.

Thanks,
Sol
