Ik gebruik Drone2Map 1.3.2. Ik heb een verzameling foto's die <\/SPAN>verzameld zijn met een dronevlucht die in WGS 84 zijn. Ik heb ze zonder <\/SPAN>de grondcontrolepunten uitgevoerd en kreeg enkele mooi uitziende mozaïeken en oppervlakken. <\/SPAN>Vervolgens probeerde ik een ander Drone2Map-project met dezelfde foto's, en deze <\/SPAN>keer probeerde ik de grondcontrolepunten toe te voegen die in een CSV werden geleverd. Ze zijn <\/SPAN>in Washington StatePlane South. Ze worden correct weergegeven in Arc Map als <\/SPAN>Washington State Plane South. Drone2Map importeert GCP's in het project en lijkt <\/SPAN>het horizontale coördinatensysteem te begrijpen, en het Sample <\/SPAN>Record lijkt te tonen dat de CSV-velden correct zijn ingelezen. Dropbox - gcp.PNG<\/A> Maar ik <\/SPAN>krijg alleen "Er zijn geen GCP's die binnen het projectgebied vallen. <\/SPAN>Controleer uw ruimtelijke referentie en verifieer of uw breedte- en <\/SPAN>lengtegraad correct zijn." Wat heb ik gemist? Moet ik de <\/SPAN>GCP's naar WSG 84 converteren? <\/SPAN><\/P><\/P>Ik heb de State Plane CSV-punten in Arcmap als XY-evenementen geïmporteerd, ze opnieuw geprojecteerd naar WGS 84, de AddXY-tool erop uitgevoerd, ze weer geëxporteerd naar CSV, en vervolgens de GCP's weer geïmporteerd in D2M. De veldtoewijzingen moesten een beetje worden aangepast om de nieuwe WGS 84-veldtoewijzingen te gebruiken, maar de punten werden goed geïmporteerd. Ik heb mijn koppelingen gemaakt en ben momenteel bezig dit opnieuw uit te voeren om te zien hoeveel de controlepunten de producten helpen. <\/SPAN><\/P><\/BODY><\/HTML>
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 "

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?

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?
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.
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'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 @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
