Francisco Yes these are the values you enter for reflectance in the Drone2Map UI. There are no units - these figures represent the % reflectance, so pure black would be 0, pure white ~0.99 , and mid gray should be near 50% = 0.50

ArcGIS Drone2Map version 2024.1 has been released! The latest version is now available for users to download from My Esri. This blog contains some highlights for what’s new in this version. For a complete list of everything new or improved, please check our help documentation. Further improvements in the quality in the 3D mesh, especially for thin structures With every release, Esri works hard to improve processing efficiency and the quality of the output data products. In 2024.1, our users will be able to reproduce thin structures like antennas, towers and bridges with better fidelity than ever before in the 3D mesh as well as 3D point cloud. The structural improvements will also be noticeable along sharp building edges. In this release, be sure to use the “ultra” setting for the point cloud density for best resolution in the 3D mesh. Enhancements to the Inspection workflow The 3D Inspection workflow, new at version 2023.2, has now been improved regarding the accuracy of inspection features created in 3D space through multisketch editing. After the image adjustment has been run, when users draw a sketch on multiple images, Drone2Map will automatically correlate between images to improve the accuracy of the 3D features. We’ve also enabled faster access to the inspection workflow. The full 3D editing capabilities of an inspection session will require that the block adjustment step has been completed, but for time critical image inspections, users can now perform an inspection without running any processing – simply create the project and proceed immediately to inspection. In this rapid workflow, the observations cannot be placed into 3D space, but users can review the drone imagery and generate a report in a matter of minutes. Catalog datasets are now time enabled Another of our features introduced in a previous version has been improved for users with multi-temporal datasets. For those who have embraced the Catalog Datasets for data sharing and project management, any region of interest showing layers captured at different times will now be automatically time enabled, enabling users to move through time for improved understanding and analysis. The time-enabled catalog can also be combined with other functionality such as the built-in animation tools to quickly create a video demonstrating, for example, the progress of construction for a new building. Adding map notes into catalog datasets The supported layer types for catalog datasets continue to grow with the addition of map note layers. Map note layers in a catalog dataset function in the same manner as other catalog layers and can be loaded into a map or shared to ArcGIS Online or ArcGIS Enterprise. Area and distance measurements in 2D and 3D Drone2Map continues to benefit from the extensive functionality in the entire ArcGIS System. Measurements of distances and areas within a Drone2Map project can now be completed in both 2D and 3D. You’ll find the “Measure” toolbox now has sections for the 2D and 3D tools: As an example, if you need to calculate the straight-line distance across a drainage canal, or the length of cable that would be dropped down into the canal to make the crossing, you can make measurements in 3D by including the DEM, or strictly in 2D (planimetric) based on your project requirements. Example showing both 2D and 3D distance measurements 3D profile showing the depth of the drainage canal (viewed in the 3D scene) Improvements for thermal infrared imagery In our prior release, we enabled creation of True Orthos from thermal infrared (IR) sensors. In version 2024.1, for those flying DJI drones with thermal IR cameras, pixel values can now be reported in temperature units (degrees Celsius or Fahrenheit). Note that installation of an additional software package is required to add this support for DJI hardware – see your MyEsri account and you can read more in this blog. DJI Zenmuse H20T Thermal True Orthomosaic processed in Drone2Map 2024.1 Smart processing improvements Our development team has applied a great effort in this release to help users understand and avoid the most common problems encountered when working with a large variety of drones and conditions. ArcGIS provides support for nearly every known coordinate system, but sometimes users are unsure of coordinate transformations that may be required for their project data. In Drone2Map version 2024.1, the Select Transformation drop-down list now displays messages that indicate whether any transformation is needed, which default transformation is being applied, or whether a transformation is needed but not found. The ArcGIS coordinate system data can be installed if necessary for additional transformations. Two additional information messages relate to helping ensure horizontal and vertical accuracy. Our typical best practice advice is to always use Ground Control Points (GCPs), but with the increased use of high accuracy GPS in form of RTK or PPK, attempting to add control can negatively impact processing. Drone2Map 2024.1 will now warn users who attempt this, and advise them to define GCPs to be Check Points (for verifying post-processing accuracy). The additional informational message, related to vertical accuracy, is to warn users if their drone altitude values appear to be incorrect. This is a very common situation for many commercial drones, and the software will compare the drone’s reported Z values to the elevation of the project site to notify the user of expected errors. Learning resources accessible from the app The processing report now includes hyperlinks in each section title of the report. Clicking a link takes you to the relevant help topic to learn more about that subject. New tutorials and blogs have been published that focus on some of the most requested subjects. Some of them are listed on the updated Drone2Map Resources page. Stay Connected If you have questions or ideas, we’d love to hear from you!

Gideon It sounds like you have not found our best practice advice for imagery at https://esriurl.com/ImageryWorkflows. You definitely should not use the Raster Dataset raster type - that will fail to include important metadata to properly configure the mosaic dataset for Landsat imagery. See the notes here https://doc.arcgis.com/en/imagery/workflows/resources/managing-medium-resolution-satellite-data.htm and specifically the recommended sample Python scripts for managing Landsat 8 scenes .

para JairoCordero Por favor, perdone mi mal español. Usé https://translate.google.com/. Solicitaste ayuda para crear el "conjunto de datos ráster", pero creo que te refieres al "conjunto de datos en mosaico". El dataset de mosaico es una estructura de datos específica en ArcGIS para acceder a imágenes y se utiliza para administrar imágenes para visualización estéreo. El dataset de mosaico se crea dentro de una geodatabase y se vincula a las imágenes de origen. Las imágenes de origen no tienen que estar dentro de la geodatabase. Puede comenzar aquí con respecto a cómo crear el conjunto de datos de mosaico https://pro.arcgis.com/en/pro-app/latest/help/data/imagery/creating-a-mosaic-dataset-pro-.htm y tenga en cuenta Tendrá que utilizar el "Tipo de ráster" adecuado para agregar imágenes junto con datos de orientación para habilitar la capacidad de visualización estéreo. Si está utilizando imágenes de satélite, el tipo de ráster tendrá el nombre del satélite. Si está utilizando imágenes de una cámara digital, el tipo de ráster debe aparecer aquí https://pro.arcgis.com/en/pro-app/latest/help/data/imagery/aerial-imagery-raster-types.htm Si está utilizando imágenes de drones o películas históricas escaneadas, háganoslo saber y le podremos asesorar más. Cuando tenga un dataset de mosaico configurado correctamente, puede calcular pares de imágenes para visualización estéreo usando esta ayuda https://pro.arcgis.com/en/pro-app/latest/tool-reference/data-management/build-stereo- modelo.htm Cody B.

Guy did you check the environment variable for resampling method? https://pro.arcgis.com/en/pro-app/latest/tool-reference/environment-settings/resampling-method.htm Usage notes The nearest neighbor option should be used for categorical data, since no new values are created. Be sure to use nearest neighbor. If your 4 rasters are not perfectly aligned at the pixel level, the software will resample pixel values. If this doesn't solve it, could you look at pixel values between input and output and give us a specific response e.g. "lower right pixel in the input (last pixel at lower right) has pixel value 13, but in output it's 15..."

I'm glad you have usable results, but for future reference I recommend you always use ground control. (Even those of you that have an RTK/PPK drone, ground control is not technically NEEDED, but we still recommend using measured points as Check points - withheld from the aerotriangulation - to verify accuracy). If you don't have accurately surveyed points, you can extract points from the Esri imagery basemap, and that will include Z values from the ArcGIS Online world terrain to ensure you get the proper Z values. Two caveats with using control from the Esri basemaps: Our basemaps are compiled from multiple sources, and we cannot provide an accuracy statement for the horizontal positions. The same is true for the DEMs used to compile the world terrain, so it's generally good everywhere but we do sometimes discover errors in the DEMs - sometimes very localized - so multiple points and careful QC are still recommended.

Varvara for most drones, the Z values *SHOULD* be the orthometric height of the drone, the height above sea level. [BUT as noted above those values can be VERY wrong] If RTK/PPK they are almost always ellipsoidal height. I have published a map at http://esriurl.com/Map4GroundElevation that can give you both orthometric and ellipsoidal heights if you are interested. (Must log in with ArcGIS Online account to get the Terrain values) Almost no drones report height above ground (because they don't have a world DEM to know where the ground is). Internally they usually have data regarding height above launch point (so if the entire project is flat, that WOULD be height above ground) but that Z value is not written to the EXIF tags of the JPG images. Our learn.arcgis.com site has some good training courses for Drone2Map. Since you're new to this, I'd advise you to review our free training. Cody B.

Varvara I agree with Mervyn. If it's not an RTK/PPK drone, the altitude values can be terrible. Until 5 months ago the worst I saw was an error of 100 meters, but I've seen a new "record" for bad values, more than 200 meters off. On the other hand, they can be very close to correct - and this can be true for ONE drone, from day to day. Without ground control points, I can almost guarantee your DSM and DTM heights will always be wrong. You said "The ground-controlled points are not applied" but you didn't include any details. Since your project coordinate system is State Plane, I am guessing you might have used GCPs but they didn't work properly? Pål_Herman_Sund also gave good advice regarding the vertical coordinate system - whether RTK/PPK or ground control points, check to see if they might be referenced to ellipsoidal height. If this doesn't solve your problem, please contact support@esri.com - they are very good and should be able to help Cody B

Thank you for posting this Pål_Herman_Sund For MelodyVeldorale and others, there are no tools that you need to run - this is just a data package to support coordinate systems and transforms, and the same package works for both ArcGIS Pro and Drone2Map. Once you have it installed, you'll have all the coordinate systems available. As noted in the previous post, if you do not have this package installed, you can find and download from your MyEsri portal. Note for anyone with an RTK-enabled drone (or PPK data) be sure to set your Image Coordinate System to agree with the drone data before processing. RTK/PPK is almost always referenced to ellipsoidal height (usually WGS84 but you will have to verify with your drone), and the default for Drone2Map currently assumes input image data is referenced to the EGM96 Geoid (not ellipsoidal height). See this recent blog for more discussion of RTK https://esriurl.com/d2mRTK Cody B

Hi Brian - since your post was nearly 3 years ago I'm not sure you need a response - but this was either processed without ground control (drone altitude values are known to be subject to large errors - I've seen vertical heights off by more than 200 meters) or it was processed with the wrong coordinate system (incorrect input coordinates if the GPS was RTK or PPK, or incorrect coordinate system for the control points if GCPs were used). This blog should be helpful for those using RTK GPS: https://www.esri.com/arcgis-blog/products/drone2map/imagery/work-with-rtk-drone-imagery-in-arcgis-drone2map/ Let us know if you still need help Cody B

Thanks for catching one of my errors. I discussed this with a colleague, and realized that my post above from earlier today offered poor advice. Assuming I'd referenced the correct tool (GPX To Features tool), you COULD follow what I offered but it's more complicated than necessary. Assuming you have Microsoft Excel, I had forgotten that Excel can automatically read and reformat the GPX file, so that is a much simpler first step to get the timestamp + lat/long/elevation (etc.) metadata into a table format. You will still need to add additional fields - email me if you need documentation on the content of the video metadata table. However it's not necessary to extract frames from the video as GIS-Cambria suggested. That is another alternative, but you'd then be limited to viewing the extracted frames, not the video. The "Oriented Imagery Classic" tools at https://www.arcgis.com/home/item.html?id=36ee0bbedca64a5a8b68d7c69ab51728 directly support video today. At risk of further confusion, note that Oriented Imagery is now being integrated as a native capability in ArcGIS Pro - read this blog to learn more - but today (Pro v3.2) video is not yet supported in the integrated version. Video support should be added in 2024 (but watch our blogs for confirmation of when this will be available).

I can help you with this. FMV in ArcGIS Pro is not suitable for 360 videos - the FMV tools assume the video field of view is on the ground, and with a 360 camera the footprint extends to the horizon in all directions. So cdanielvarons is on the right track to use Oriented Imagery but I agree with GIS-Cambria that "...it will take some work...". The starting point is to use this GP tool https://pro.arcgis.com/en/pro-app/latest/tool-reference/conversion/features-to-gpx.htm to generate a point feature class, then you'll have to extract the required fields from the attribute table and edit to create a *.csv with the required metadata fields. You'll be missing some of the required fields (e.g. horizontalFOV = 360, verticalFOV = TBD, UnixTimeStamp in MICROseconds, more) but you can insert nominal values. If you need a description and example of the video metadata, send me email at cbenkelman@esri.com. Note the video and metadata are asynchronous so you don't need metadata for every second or every video frame - as long as your metadata and video start at the same time, our tools can work with the video.
