Hi Tara Sorry but would you mind starting a new post and explaining exactly what you're seeing?  This thread began 8 years ago, and the software has changed dramatically since that time.  Screenshots of your project would be helpful, if that doesn't reveal proprietary information.  If you have a lot of heavy canopy or water, the image correlation is fundamentally challenging.   Cody B.  ...

Cameron Several things appear wrong here.  It appears to be multispectral data but your spectral bands are in the wrong sequence for the RGB display, and you should not have seamlines in the default True Ortho output (unless you're intentionally using the Image Collection?).  Are you using an old version of Drone2Map Standard?  Current version is 2024.1.1. Also, I can't make out any blurring in the sample you sent.  Let us know what camera you are using, and if you can send us few of the source images.  I'll send you a direct message. Cody B.  ...

Hi Ramon I've been talking with Mark about your data - I'm sure we can make this work better.  I wanted to confirm that you are selecting all of your ground control points on the ground?  If you are surveying your own points with GPS, you can use control on tops of buildings - but when extracting control from the map note that the Z value comes from Esri's World Terrain which provides an estimate of the ground height, not including buildings.   Also, can you let us know how you are controlling your drone flight?  The flight line direction and spacing appear to be somewhat  variable - so if you have inconsistent overlap and a lot of buildings in the project area, this can also reduce accuracy. For future flights, if you have access to an iPad (and depending on the model of drone) I'd recommend you use our drone flight control app, ArcGIS Flight.  (See http://esriurl.com/ArcGISflight and also https://community.esri.com/t5/arcgis-flight-blog/arcgis-flight-supported-aircraft-and-cameras/ba-p/1502473?rsource=https:%2F%2Fesriurl.com%2Farcgis-flight-app-supported-drones ) Best wishes Cody   ...

Hello everyone. Esri's drone flight control appfor iPad was updated earlier this month.  The app has now been renamed "ArcGIS Flight" to emphasize compatibility with a range of ArcGIS applications, including Site Scan, Drone2Map, ArcGIS Reality, and ArcGIS Online. You can find this app by navigating to https://esriurl.com/ArcGISflight on your iPad Cody B.   ... View more

@RAMON_VERANO How are you combining the true orthos?  Are you using Drone2Map, ArcGIS Pro, or some other method? Cody B.  ... View more

Hello I'm not sure I understand your status.  You mentioned processing this data before installing the DJI software - was processing successful previously, and now failing only after adding the DJI code?  Are you using the current version (2024.1, or 2024.1.1 which was just released 27 June)?   If you are able to share the imagery with us, I can provide an FTP link.

Hello all In version 2024.1 we've enabled addition of DJI software that will enable correlation to temperature.  Could you try the new version (with optional DJI software installed - access through your MyEsri account) and let us know if it's working?   Thanks Cody B.  ... View more

Josh Yes, the altitude warning is a new feature at v2024.1.  Incorrect altitudes are one of the most common problems for our users - This warning was added seeking to avoid confusion and problems.  I've seen drones report altitudes with errors more than 100 m - although this should not happen with RTK.  Users with RTK drones should have highly accurate (X,Y,Z) values but note RTK is almost always referenced to ellipsoidal height, not orthometric height - so with RTK or PPK you must set the proper vertical datum.    Lacking RTK/PPK, I recommend *always* using control points.  (With RTK, I recommend using check points). If you have surveyed points, be sure you know the proper Horizontal and Vertical coordinate systems for the points.  If you do not have surveyed points, you can extract points from the Esri Imagery Basemap - those points will not have any documented accuracy but *will* ensure your 3D products don't float above or sink below the basemap in a 3D scene.

Hi Everyone Sorry I never saw the later posts.  This thread is now very old, but if anyone is still having license issues please let me know. Originally the license simply said "Drone2Map" We then separated the product into 2 license levels - "Standard" for 2D processing only, "Advanced" for 2D & 3D.    As of now June 2024 you should never see "Drone2Map" in the license manager - it should be either "Drone2Map Standard" or "Drone2Map Advanced" (or both if your organization has both).  Cody B ...

Francisco Do those values appear to be incorrect for your project site, assuming the pixels represent temperature in degrees Celsius?   I was going to show you that you can convert temperature units to Fahrenheit under Settings ...but I assume this project is in Spain, and you'd want Celsius.  (Note if you change units, you would have to reprocess).   Were you hoping to create a mosaic showing the original pixel values, from 5000 to 7000?

Javier Sorry for the delay - I missed your message. 1) you said you followed the configuration in the documentation - do you mean from the workflow best practices starting here  https://doc.arcgis.com/en/imagery/workflows/resources/managing-medium-resolution-satellite-data.htm  where you found and downloaded  sample Python scripts for managing Sentinel-2 scenes ? 2) You said you're getting a warning - do you mean the error message above: "Error: 8004818c: No new mosaic dataset item was added." ? Can you send a screenshot or directory listing showing your Sentinel-2 files?  The folder and file structure is somewhat complicated so I want to be sure you have all the necessary files.   If you view the folder in the Catalog pane in ArcGIS Pro, do you see the Raster Product icon  and if you drop that into the map, does that one image load successfully?  https://desktop.arcgis.com/en/arcmap/latest/manage-data/raster-and-images/what-is-a-raster-product.htm (I understand that you're seeking to make a mosaic dataset with multiple scenes, but this last test will help confirm you have all the necessary source files) Cody     ...

Lars In the current release, this value is not editable, for control points extracted from the imagery basemap (or your own ortho layer).  If you have control points in a *.csv file, that file can define the uncertainty of each individual point. I can't yet promise which future release will enable editing of the uncertainty fields but this is an area we are actively working.   We know this is an important issue. Last, I want to congratulate you for figuring out the workaround!  I know it's cumbersome but it does provide a method for changing these values.  Cody B.    ... View more

I'm sorry I did not see this question for 10 months.  No, the software cannot autopopulate the % reflectance value for the panel.  Your drone will record an image, with brightness levels in the range of 0..255 assuming an 8 bit sensor.  The calibration process is seeking to answer "What is the average pixel value on the image when it views a gray object with [for example] 50% reflectance?" This provides a data point to convert pixel values from 0..255 into values representing percent reflectance.  (It is generally assumed that 0% reflectance would result in a pixel value of 0, so these two reference points define the linear equation from pixels to reflectance - but this depends on the specific drone and camera.  Esri implements calibration calculations recommended by the manufacturer, so we follow their specifications for this process).     ...

Francisco for Radiometric Quantity Type you should use Reflectance.  See help here:  https://doc.arcgis.com/en/drone2map/latest/help/radiometric-calibration.htm At this time we have not implemented support for the DLS inside Drone2Map.  What I would recommend is to capture images of the reflectance panel before and after your flight, and look at the DLS values for those calibration images and also for the images captured over your project site.  If the "before" and "after" calibration images have DLS values that are very similar (within a few %) and your flight images show consistent DLS values, your results should still be valid.   If the DLS data indicates significant changes during the flight (perhaps more than ~15%, but this is just an estimate) then you would need to consider how changes in your multispectral values from early vs. late in the flight may appear in your data.  e.g. if your flightlines run north/south and proceed from west to east, and illumination drops by 15% from first image to last, your spectral values MAY show a bias from west to east. However, if you're using NDVI, this concern is largely reduced, since the normalization of the NDVI compensates for variable illumination.  Further, your drone will most likely change the exposure parameters to compensate for the change in illumination.   ...
