Digitizing Irrigation Buildings (Point)

1. Before digitizing, a shp or several shp that are in one folder must first enter Editing mode by right-           clicking the layer to be edited or to be digitized (Irrigation Channel) Edit Features

️    Start Editing.

2. Click the Create Feature Logo in the Editor toolbar on the side menu Create Feature select the irrigation     building layer in the Construction Tools select Point the pointer will change to a sign

3. Start digitizing the location of the irrigation building, by directly placing the point according to its        position in the satellite image.

4. If you previously had the coordinates, then input the location of this building can be done by entering     the X and Y values of the coordinates. The method is by right-clicking anywhere on the display (still     in editing mode) clicking Absolute X, Y entering the values of X and Y pressing the Enter key.

Digitizing Irrigation Channels (Polyline)

1. Same as before, when delineating, a shp or several shp that are in one folder must first enter                 Editing mode by right-clicking the layer to be edited or digitized (Irrigation Channel) Edit Features         Start Editing.

2. Click the Create Feature Logo in the Editor toolbar on the side menu Create Feature select the             irrigation channel shp in the Construction Tools select Line the pointer will change to a sign +

3. Start digitizing on screen by tracing the irrigation canal based on observations through satellite           imagery at a level of detail at a scale of 1:5,000. If needed, zoom to a larger scale, because the               resolution of satellite imagery can accommodate up to 1:2,000. To end digitizing double click on the       end of the channel. Do digitization in all irrigation channels both in the primary, secondary to tertiary     irrigation networks.

4. If there is a vertex error in digitizing, then you can undo it by pressing the Ctrl+Z combination on         the keyboard. Undo can be done with the note that the digitization has not been terminated at the            end of the channel. If the digitization has been terminated then the repair is done with the editing            tool. The method will be explained in the next chapter in the Editing Data section.

Digitizing Irrigation Area (Polygon)

1. Click the Create Feature Logo in the Editor toolbar on the side menu Create Feature select shp                Irrigation Area in the Construction Tools select Polygon the pointer will change to a sign  +

2. Start doing on screen digitization as well as line vector digitization by tracing the irrigation area based on observations through satellite imagery at a level of detail scale 1:5,000. If needed, zoom to a larger scale, because the resolution of satellite imagery can accommodate up to 1:2,000. Same with digitizing the line, when finished, click 2 times to form a delineation of the irrigation area.

3. If needed, there is a feature that is commonly used in on-screen digitization, namely Cut Polygon. Its function is to cut a polygon into 2 parts with the size as needed. Cutting can be done from the outer line to the outer line in a polygon or it can also be done by cutting the polygons within the polygon to be cut. To be able to use this feature, first select the polygon to be cut using the Edit Tool  on the Editors toolbar. Click Edit Tool select

polygon click Cut Polygon  ️ do the digitization starting from the outer line to the other outer line ️ click 2 times when you are done digitizing.

4. If there is an error in digitizing, then like line vectors, the delineation of polygons can be corrected using the undo feature as long as the digitization process has not ended. If it is finished, then data editing must be done (explained in the next chapter).

5. If the digitization process is complete, then the editing process must be saved and dismissed first so that the data that has been created is recorded and can be used in the next stage. How: click Editor in the Editor toolbar Save Editing Stop Edits.
