If the first layer does not have a coordinate system, ArcMap will set the coordinate system to Unknown. As you add subsequent layers, they are automatically transformed to the data frame's In ArcGIS, you can use data collected from a GPS device to create a shapefile containing points, lines, or polygon features. For more about shapefiles, see Shapefile in Wikipedia. Note: With most ArcGIS functions and tools, several methods can accomplish the same task.
