Why don't you just project the second dataset into Albers Equal Area to match the NLDC? ... View more

ArcMap can project on the fly, so If the datasets did not line up correctly to begin with, then one of them was likely defined incorrectly. I would be less inclined to think that the NLCD data was incorrect, so the culprit is probably the recently created one. Have you tried defining the original dataset to zone 16?  Basically, if they didn't line up to begin with, then reprojecting them won't help. You need to find the correct original projection. Also, the data frame will have the projection of the first data set you add to your project. Sometimes it s better to start a new project and bring your dataset with the correct projecion in first to make them the same. ... View more

When should I use the Define Projection tool and the Project tool? I wasn't sure if I explained that as well as the above document does. ... View more

Hi Ashley, define projection is for defining the original projection. You don't use it to change a projection, nor should you do that in data frame properties, that just sets it for your data frame, not the actual datasets. You need to use the Project Raster tool to change a projection, and the Project tool if it is a feature dataset. What was the original projection of your second dataset? It sounds like you might have defined that wrong to begin with. Did they line up before you attempted the reprojection? If not then then most likely it was defined incorrectly. Once you have the original projections defined correctly, using define projection, they should line up, and then you can project them into a new projection. ... View more

Hi Martin, I cam up with another suggestions. The Extend Line tool in the Editing Toolbox would probably work great for this... Extend line ... View more

Hmmm, from his description I get the impression that it's just one shapefile. So how would you tackle that problem? I couldn't think of any easy way. ... View more

I'm not sure how feasible your idea is, just because DEMs don't usually contain bathymetry information, ie. the elevation under the water. Some sort of spatial analysis of your DEM might work better, perhaps looking for the breakpoint where the DEM becomes flat at the surface of the water, and then using Con, or a Reclass to separate out just those water areas, and converting those to polygons. Just a thought. ... View more

Hey Peng, It's customary to mark an answer as correct if it worked for you. Thanks! ... View more

At the bottom of my answer there should be a star next to a box that says correct answer I think. You can also mark any answers as helpful by clicking yes next to the word helpful. Thanks so much! ... View more

No problem, it is polite though to mark my answer as the correct one, rather than assumed answered, for future reference. ... View more
