I was trying to convert a group of x and y coordinates into a point shapefile. I use ArcMap 10.2, Here is what I did:
(1) put x and y (in numerical values) in columns in Excel and convert it into a .cvs file;
(2) in ArcMap 10.2, go to file> add data>add XY data;
(3) for coordinate system, I imported the projection of my reference shapefile;
(4) click ok.
(5) export the layer into a shapefile by right click it and go to data>export data;
After I got the shapefile, I realized that it cannot be in line my reference map though both have the same projection. When I check the converted shapefile, I noticed that its EXTENT is different from that of the reference map.
Could anyone tell me what I did wrong and how to fix this problem?
