Import field boundaries as shapefile or GeoJSON
To import field boundaries as shapefile:
1. After importing images the option to import field boundaries is available.
2. To import a field boundary, click the FIELD BOUNDARIES menu, then click Import.
3. Navigate to the folder containing the file and select it.
4. Click Open.
5. Select the field boundary, click TRIM.
6. Select the layers to trim, click TRIM
Draw field boundaries
To draw a custom polygon field boundary:
1. After importing images the option to draw field boundary is available.
2. To draw a field boundary, click the FIELD BOUNDARIES menu, then click Add.
3. Left-click to start drawing.
4. Click Accept to finish the draw.
Reuse field boundaries
To reuse a field boundary:
1. After importing or creating a new boundary the option to reuse a field boundary is available.
2. Below the FIELD BOUNDARIES menu select the field boundary to be reused.
3. Click the FIELD BOUNDARIES menu, then click Reuse.
4. Drag the white dots to modify the field boundary.
5. Click Accept to apply the modifications or Cancel to keep the original field boundary.
6. A new field boundary appers automatically.
Trim layers
To trim layers with an imported shapefile, GeoJSON or custom drawn field boundary:
1. Below the FIELD BOUNDARIES menu select the field boundary to be trimmed.
2. Select the layers to trim and click TRIM.
Edit field boundaries
To edit field boundaries:
1. Below the FIELD BOUNDARIES menu select the field boundary to be edit.
2. Toggle on the Edit button.
3. Drag the white dots to modify the field boundary.
4. Click the "plus" sign to create more corners or vertices.
5. To remove a vertex, drag the dot of the vertex that you would like to delete on top of any other dot. Wait until a red halo appears around the selected vertex then release the mouse button.
6. Toggle off the Edit button to stop editing or click Cancel to keep the original field boundary.
7. Add a name to the field boundary.
8. Close the window BOUNDARY.
Delete field boundaries
To delete field boundaries:
1. Click the trash bin icon of the field boundary you want to remove.
2. Click YES in the confirmation box.
Hi,
how can I create/import/draw/trim boundaries of the specific area/field in Pix4D Mapper?
Thank you!
Hi Michal,
Boundaries in fields are regions in mapper. You can draw/import regions (https://support.pix4d.com/hc/en-us/articles/204769419-How-to-create-a-Region-with-the-Index-Calculator) and get the index map for that region only.
If you want DSM, ortho, index (all the outputs) for a certain area, you have to draw a processing area (https://support.pix4d.com/hc/en-us/articles/202560179-How-to-select-/-draw-the-Processing-Area)
Hi Momtanu,
thank you for your promt reply, however, the second link does not work, can you confirm please?
Hi Michal, my bad, here is the working link:

Hi,
I need to process several areas within one batch. I work in sugarcane and the lots have an average of 15 hectares and are subdivided by internal roads into sublots which I can define using the boundary tools. My goal is to generate the indices (NDVI) of these sublots all together eliminating the internal roads. Is it possible to define serveal limits (sublots) within the same lot an generate the indices at same time if i need to process them one by one?
Hey Felipe,
We replied to your ticket. Thanks for contacting us. At the moment this can be a workflow to follow: You can draw all the field boundaries. Then, you trim the orthomosaic with each boundary, and then generate and NDVI of each trimmed orthomosaic. I would recommend this workflow because you will get accurate results in that way. For now, it is not possible to hide the field boundaries, but I am passing this request to my team. Trial plot projects are in our roadmap, so we fully appreciate your feedback and feature requests in this regard. You can add any Pix4Dfields feature request here.
Cheers,
