How to change a projection in a project?
Open Data Management Tools → Projections and Transformations → Feature → Project. The Project dialog box will appear. Under Input Data Set or Feature Class, choose the Map Layer for which you want to change the Projection. It can be an entirely new Map Layer or Shapefile or one that is already being used in a Map Project.
How do I define or change map projection in ArcGIS?
Answer. Individual shapefiles have a projection, and the data frame has a projection. Both of these need to be defined for your data to display properly. Note that if there is no projection defined, you must first define it before you try to change it.
How are map layers supposed to work together?
In order for multiple map layers to work properly together, they must all use the same Coordinate System. The following directions will walk you through the process of checking your Map Layers/Shapefiles to find out which Coordinate System they are using and how to change them if they are different.
Why does the Las dataset disappear in ArcMap?
If the projection of the ArcMap data frame is changed, some or all the features in the LAS dataset disappear. While the LAS dataset (LASD) has a projection defined, the LAS files which are loaded into the LAS dataset do not have projections defined.
How to change the projection of the native layer?
For example if the native layer projection is Mercator/WGS84 and the view/export projection is set to Geographic (lat/lon)/WGS84, exporting to a new Shapefile will generate one with Geographic/WGS84 coordinates. They will have been converted from the Mercator easting/northing values of the native layer.
How can I change the projection of my mapper?
So long as your edits didn’t involve reprojection or anything like that, you can simply select all of your layers in the Control Center, press Options, then go to the Projection tab and change the native projection interpretation of the layers to the new correct one and all should be fine.
How is web layer’s data source has a different projection?
The web layer being shared will be in the projection of your map. One of the layers in your map is in a different coordinate system than that of the map. This requires on-the-fly projection, which can affect drawing performance. The value parameter indicates the projection of the data source.
