I have downloaded the federal wetland shape file for New York State and the prj file indicates it to be on NAD 83 Albers. After many attempts and searching on line I can't get the shape file to import into Autocad Map 2013 (with Carlson Civil/Survey) correctly. When the shape file comes in it is significantly out of position. I have tried without success using Esri ArcMap to change the projection, but I am not proficient with ArcMap. I figure someone else must have bumped into this and knows what to do. Other governmental agency shape files from NYS and FEMA were no problem to import. Thank you for any assistance.

Any chance the shape files are metric?

Yes, the shape file is in metric. The drawing I'm trying to import into has our County boundary footprint in it that is in US feet. I have tried playing with the settings for metric/US feet. Thank you.

If it has a prj file, aka the coordinate reference system is already defined, open up ArcToolbox and browse to Data Management toolbox, Projections and Transformations toolset, and select the Project Tool (you can also search for the tool).

For the output coordinate system, you can use a state plane or UTM zone, a custom Albers (switch the units to either foot definition), etc. The Project Tool will create a new 'feature class' that's using the selected output coordinate system. It will default to the default file geodatabase, so if you want a shapefile in another location, browse to the folder, then type in the new shapefile name + .shp.

When setting the output coordinate system, browse into the Projected Coordinate Systems, then either State Plane or UTM, or right-click the current coordinate system and select copy and modify if you want to customize it.

I had issues re-projecting some Teal Albers stuff (California state wide data) to state plane (don't know if that is what you are trying to do).

If I remember correctly it was a two step process because there wasn't a direct transformation between the two.

I'm going to have to strain my brain trying to remember what I did.

Thanks for your help, it got me on track to creating an export to CAD that came in to Autocad correctly.
