Merging data sources

I am new to GM, but trying to create terrain using multiple data sources. One source is US Elevation Data (NED, 10m). The other source is a shape file consisting of GIS points.

I have merged the 2 sources and aligned the data horizontally using the projection location saved in the GIS shape file. But vertically the data is mismatched. Is there an "easy" way to align the GIS points the the NED data vertically?

Check out the attached image showing the result of my merged data when viewed in 3D. The data from the shape file is too low.
