The processingof the images went well  and the NDVI map, index map are ready. The prescription to the field in terms of kg/ha was made and the map was exported into .shp format. When it’s uploaded into the tractor computer (Muller Basic Terminal) it shows only application rates but the map can’t be seen by the computer. What was made wrong? Although a month ago a contractor mapped a few fields for us BUT processed the images at Airinov Co. and all maps in .shp worked fine in the tractor computer. Thank you   ---

Hi Oleg, As per Muller Elektonik user manual we can see that in order to be able to use a shp prescription map on the terminal, you have to convert it into an ISO-XML task. As the prescription maps that Pix4D Desktop generates are in .shp format we believe that you will first need to convert them and after import them in to console. Cheers, ---

Dear Ina   I’m interested in this topic. Could you let me know the convert SW from Geotiff / Shape to ISO-XML?   Mirai Koujimaru ---

Hi Mirai, I have never tried it from my side. But I can see that they have a converter for this: [https://www.mueller-elektronik.de/en/products/shape-iso-xml-converter/ ](https://www.mueller-elektronik.de/en/products/shape-iso-xml-converter/%C2%A0) If you try it for yourself, please comment here other Pix4D users may also be interested 🙂 Have a good day, Ina ---

Dear Ina   The conversion was succeeded. But it seems not to be correct data.   Now I discuss with senseFly support team. I’ll ask again if I need your help.   Best regards, ---

Hi Ina, Muller can work with these 2 types of files, shp files being much easier to use on a tractor screen. I did some tests with different equipment recently and it seems like we have to make transformations to make it work with most displays Could you let me know if Pix4D will evolve to be compatible with tractor screens ? If not, I will try to find a way to do the modifications with other softwares (QGIS or Farmworks)   Thanks ---

Hi Paul, My name is Sam, I am the Technical Support Engineer for our new product Pix4Dfields which is dedicated to agriculture. If you have not yet had a chance to try it, I would recommend visiting [https://fields.pix4d.com/welcome](https://fields.pix4d.com/welcome) where you can try the software for free for a month. Pix4Dfields allows you to generate orthomosaics which in turn can create vegetation indices (e.g. NDVI, NDRE).  Our team have developed tools which analyse the index map and produce a zonation, used by variable rate applications.  Whilst the NDVI is a geotiff, the zonation and associated prescription rates can be exported as shapefiles and should be compatible with the tractor terminus. This will not require the use of QGIS to be compatible.  We are working to add ISO-XML export functionality in the near future. Kind regards, Sam ---

Hi Sam! I have been following Ina for some time now, like her I am very interested in system integration and spectral analyses. I wish I could be more involved in this side of spatial analyst, but till then I’ve added you to my follow list as well if you don’t mind. Hi Paul! The integration of this technology into modern agriculture is fascinating to me, but I suspect it is frustrating and time consuming for yourself. Wish I could help. Thanks Gary   ---

Hi Sam,   Thanks a lot for your quick response. I am already using Pix4D (the company I work for is selling Parrot drones for agriculture). I have tried SHP from Pix4DField with an XML converter to use on a Kverneland ISOMATCH screen but it’s not working. To be fair, even SHP files are not standard from one screen manufacturer to another. I know a few guys around so I will do some tests and let you know with who it’s working or not About the ISO XML, this is very interesting. If you are looking for people to test it, just let me know, I can have access to a ISOMATCH Tellus screen easily. Thanks again ---

Hi Paul and Gary, Thanks for your eagerness to be involved, having come from industry I know how difficult it can be for file formats to work with the range of machinery on the market.  If you are able to provide information about how the machinery you use handles the files then we can see how easy it is to support. Feel free to write to [agriculture@pix4d.com](mailto:agriculture@pix4d.com) so I can share it with my colleagues in development and follow up with you more directly.  Our office here in Berlin is dedicated to agriculture R&D and seeks to build / improve Pix4Dfields functionality with the input of farmers, agronomists, breeders and the user community. I agree that having a shapefile work across many machines is complicated - there is no standard shapefile!  Our aim is to ensure our outputs are compatible with the converters, machine terminals (directly if possible) or farm management platforms. Thanks and look forward to hearing from you, Sam ---

Hi Sam, I ask a friend at Muller France to do a test with a SHP file from Pix4D Field and it works perfectly on their 2 main products (ME Touch800 and ME Basic-Terminal). This is the application map generated by Pix4D Field This is the application map displayed on a ME Basic-Terminal And now on a ME Touch800
