Estoy usando Drone2Map 1.3.2. Tengo una colección de fotos que fueron <\/SPAN>recogidas con un vuelo de dron que están en WGS 84. Las procesé sin <\/SPAN>los puntos de control terrestre y obtuve algunos mosaicos y superficies con buen aspecto. <\/SPAN>Luego intenté otro proyecto en Drone2Map con las mismas fotos, y esta <\/SPAN>vez intenté agregar los puntos de control terrestre proporcionados en un CSV. Están <\/SPAN>en Washington StatePlane South. Se mapean correctamente en Arc Map como <\/SPAN>Washington State Plane South. La importación de GCPs en Drone2Map parece <\/SPAN>entender el sistema de coordenadas horizontal, y el Registro de Muestra parece mostrar que los campos del CSV fueron leídos correctamente. Dropbox - gcp.PNG<\/A> Pero solo puedo obtener "No hay GCPs que caigan dentro del área del proyecto. <\/SPAN>Por favor, verifique su referencia espacial y confirme que su latitud y <\/SPAN>longitud son correctas." ¿Qué me perdí? ¿Necesito convertir los <\/SPAN>GCPs a WSG 84? <\/SPAN><\/P><\/P>Importé los puntos CSV de State Plane en Arcmap como eventos XY, los reproyecté a WGS 84, ejecuté la herramienta AddXY sobre ellos, los exporté nuevamente a CSV, y luego importé los GCPs de nuevo en D2M. Las asignaciones de campos tuvieron que ajustarse un poco para usar las nuevas asignaciones de campos WGS 84, pero los puntos se importaron bien. Creé mis enlaces y actualmente estoy ejecutando esto nuevamente para ver cuánto ayudan los puntos de control a los productos. <\/SPAN><\/P><\/BODY><\/HTML>
Hi @JEngvall,This is a pretty old post so the way we handle coordinate systems from that version has changed a bit. When importing control we do a validation of the X/Y (lat/long) fields to make sure that the points appear over the flight area. Do you happen to have points that are far away from the flight path? If so, then they might be causing the problem.
I would also double check that the field mappings didn't get swapped for latitude and longitude as sometimes the table formatting, especially tables without headers, can cause the automated field detection to not match properly. If you continue to have trouble importing your control, then please share the image coordinate system you are using and the one you are defining for the control. Regards,
Mark
I'm having the same issue. The photos is reprojected fine but the control points does not work: "No control could be imported into your project. Please check that the control you are trying to import is in the correct spatial reference and the control is within the project area." The control points are the same coordinate system as the project but still does not work.
Hi there,I have similar question.I'm trying to import GCPs into Drone2map version 2.3.Images from the drone are in WGS 84 so I left all the project in this coordinate system.Now I would like to improve project accuracy by GCPs, however according to this procedure:
I can not click on "OK". What might be the problem please?I can have GCPs either in national geographic system - "JTSK Krovak East North" or WGS.I tried to import both but without a success.I am looking forward for any suggestions.
I figured out that transformation on the fly does work in Drone2Map. I had just been trying to use the wrong input coordinate system for the GCPs. Drone2Map presents a lot of different kinds of NAD 1983 Washington State Plane South, and, unlike my ArcMap, none are saved to "favorites". NAD 83 Washington State Plane South 102349 sends the GCPs out of the project area. NAD 83 Washington State Plane South Feet 2927 places the GCPs correctly.
It looks like I don't have a processing report for this run. The report folder just has a folder html with the esri logo in it. I think that would be consistent with just stopping the project when I encountered the message that there were no control points in the project area. Would the report for the run in which I used reprojected coordinates be helpful?

Sorry for the delay in my response - I missed your original post. You *should* be able to use GCPs in state plane coordinates; there must be some other cause for this problem. Can you send us your processing report?

ESRI Technical support told me that having a different coordinate system for the ground control points just doesn't work. D2M is unable to reproject GCPs on the fly. That I should use my workaround workflow of changing the projection of the GCPs. But it seems strange that the product would have the user set the projection system for the photos in one area of the workflow, then have a way to define the projection system of the ground control points in another part of the workflow if it doesn't work.
Tech support pointed me to bug ENH-000103747, but this enhancement request doesn't match well to what I am experiencing. The bug description is "
