Estou usando o Drone2Map 1.3.2. Tenho uma coleção de fotos que foram coletadas com um voo de drone que estão em WGS 84. Eu as processei sem os pontos de controle no solo e obtive alguns mosaicos e superfícies com boa aparência. Então, tentei outro projeto no Drone2Map com as mesmas fotos, e desta vez tentei adicionar os pontos de controle no solo fornecidos em um CSV. Eles estão no Washington StatePlane South. Eles são mapeados corretamente no Arc Map como Washington State Plane South. A importação dos GCPs para o projeto no Drone2Map parece entender o sistema de coordenadas horizontal, e o Registro de Amostra parece mostrar que os campos do CSV foram lidos corretamente. Dropbox - gcp.PNG Mas eu só consigo obter "Não há GCPs que caiam dentro da área do projeto. Por favor, verifique sua referência espacial e confirme se sua latitude e longitude estão corretas." O que eu perdi? Preciso converter os GCPs para WSG 84? Importei os pontos CSV do State Plane para o Arcmap como eventos XY, reprojetei-os para WGS 84, executei a ferramenta AddXY neles, exportei-os de volta para CSV e então importei os GCPs novamente para o D2M. Os mapeamentos dos campos tiveram que ser ajustados um pouco para usar os novos mapeamentos de campo WGS 84, mas os pontos foram importados corretamente. Criei meus links e atualmente estou executando isso novamente para ver quanto os pontos de controle ajudam nos produtos.

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.

Posso não misturar sistemas de coordenadas no Drone2Map?

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 "

In Drone2Map, For gcp that use a different Datum than the Drone imagery, the Software should indicate, in documentation or in the product as a message, what datum transformation is being applied and/or allow this to be applied to the processing results as well."

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?

PaulHuffman

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'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
