私はDrone2Map 1.3.2を使用しています。ドローン飛行で収集された写真のコレクションがあり、それらはWGS 84の座標系です。<\/SPAN>地上制御点なしで処理を実行し、きれいなモザイクと表面を得ました。<\/SPAN>次に、同じ写真を使って別のDrone2Mapプロジェクトを試み、今回はCSVで提供された地上制御点を追加しようとしました。<\/SPAN>それらはWashington StatePlane Southの座標系です。Arc Mapでは正しくWashington State Plane Southとしてマッピングされます。Drone2MapのGCPインポートはプロジェクトに水平座標系を認識させるようですし、サンプルレコードはCSVフィールドが正しく読み込まれていることを示しています。Dropbox - gcp.PNG<\/A> しかし、「プロジェクト領域内に該当するGCPがありません。空間参照を確認し、緯度経度が正しいか検証してください。」というメッセージしか得られません。何を見落としたのでしょうか？GCPをWSG 84に変換する必要がありますか？<\/SPAN><\/P><\/P>State PlaneのCSVポイントをArcmapにXYイベントとして取り込み、WGS 84に再投影し、AddXYツールを実行してからCSVにエクスポートし、その後GCPをD2Mに再インポートしました。フィールドマッピングは新しいWGS 84のフィールドマッピングに合わせて少し調整しましたが、ポイントは問題なくインポートされました。リンクを作成し、現在この処理を再度実行して制御点が製品にどれだけ役立つか確認しています。<\/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 "
