Convert Points into a Polygon

Jump to: navigation, search


It allows to convert a selection of points into a polygon.  This tool is very useful, for example for converting the GPS points of the edges of a field into a shape that represents the area of the field.  This is a simple and easy way to georeference a field.

1. Select the points that you want to convert into a polygon.


2. Click on the “Convert points into a polygon” icon.

3. In the following window, you can set the order of the points sequence. By default, GeoAgro GIS shows them in the order they were taken in the field, therefore there might be some overlapping or union that are not correct, but that can be corrected using this tool.

Order in which the points were drawn.


Select one point at a time (the selected point will appear blue) and change its position in the list using the up Image:GIS_gps_Tool_05_02A.jpg and down Image:GIS_gps_Tool_05_02B.jpg arrows on the right of the window.

If there is a selected point that is not supposed to be part of the polygon, click on the Image:GIS_gps_Tool_05_02C.jpg tool for deselecting.

If you would like to sort the points alphabetically or sorted by number, click on Image:GIS_gps_Tool_05_02D.jpg.

You will see that the changes will modify the line. Arrange the points until the overlapping disappears.

Order in which the points were set by the user.


Select the Identifier of the resulting polygon by selecting the point that will be assigned as the name of the object (in this example is 1).

4. Finally, click on “Accept” and the conversion will be performed.
