How to clip data to polygon on Mapinfo Professional

Its been a while not write any post on this GIS blog. Here I just want to give a little update in How to clip data to polygon on Mapinfo Professional. Off course I have Encom Discover software integrated to my Mapinfo. Its pretty easy to clip data inside a polygon on Mapinfo.

Data Preparation

In order to cut or clip data to a polygon make sure we have the following layers opened in Mapinfo Professional:

  • Data/layer to be clipped
  • Polygon layer
The polygon must be saved in a separate file, not in cosmetic layer. 

Steps to clip data to polygon on Mapinfo

Step 1. Open the Tables (both the polygon and the data). See the following example
As you can see, I have point layer (blue) and polygon layer (red). I will cut the blue point layer with the red polygon. I will save data points inside the red polygon.

Step 2. Make sure you click/select the polygon to cut the data with. And then go to Discover | Object Editing | Clip to Polygon. 
The new window will open up and the select which table that will be clipped by the polygon. You may also need to specify the new file name. You can also change some options available on the left. When you press OK you will be asked to give the destination folder. 


Thanks for reading this How to clip data to polygon on Mapinfo Professional. See you.
