I tried changing the shapefiles by projecting them by only using the Project tool and I made sure that the data frame properties were set to the correct projection. I see the properties of the shapefile and the data frame properties say that they are all set to Albers Equal Area Conic but when they are displayed in a map it doesn't look like it. Here is the image that I see.

Here is what one of my three source tabs looks like. They all have the same projected coordinate system and even the same geographic coordinate system.enter image description here

  • I'm not familiar with the coordinate ranges expected for the Projected Coordinate System that you are using.

  • Can you edit your question to show the layer property page of one of the original datasets? It looks like you have a mix of lat/lon and projected coordinates in the extent of the new files. We need to see the source extent too.

Applying coordinate systems to datasets and using them within the coordinate system of a data frame can be confusing.

I think the way to sort it out is:

  1. Look at the Properties of each shapefile to see what coordinate range is present.
    • If they are -180 < long < 180 and -90 < lat < 90 then they are in a Geographic Coordinate System and you use Define Projection to give it one.
    • If they are much larger numbers (usually 6 or 7 digits) then they are in a Projected Coordinate System and you use Define Projection to give it one.
  2. If you want to display shapefiles in any coordinate system (as long as it has the correct coordinate system defined on it), in Albers Equal Area Conic, then set that as the coordinate system on your data frame.
  3. Add your shapefiles into that data frame and they will display in Albers Equal Area Conic, irrespective of the coordinate system(s) that they are stored in.
  4. If you want your shapefiles to be stored in a Projected Coordinate System, when they are currently correctly defined to be in a Geographic Coordinate System then, as a separate exercise, you can use the Project tool to project them.

Albers Equal Area Conic is a Projected Coordinate System.

Your question does not mention which, if any, Geographic Coordinate System your shapefile coordinates may be from.

For all questions like this one I think it is important to show a screenshot from the Source tab of the Layer Properties like the one below. From it you can see the 6-7 digit numbers for the extent which is the range expected for a Projected Coordinate System. Then by scrolling down in the Data Source section you can see that it has a Projected Coordinate System of GDA_1994_MGA_Zone_56 defined on it.

  • I looked at the source tab. It said that the projected coordinate system was Albers Equal Area Conic, but the map still looked like that shown above.

  • I just posted above what my source tab that I am seeing looks like.

  • The geographic coordinate system information is below the screenshot you posted. It should list a datum such as D_WGS_1984.
