Hello,   I am going to have to do a lot of our USDA US Forest service Region 2 forest reserves that was scanned by the NARA and they have asked me to do these. The maps are very old dated back to 1897   My question to you, for those to have done, recommend or suggest me to do a best practice which software to do georeference in ArcGIS 10.5.1 or… (Show more)

Hi there,   I am trying to experiment with using Ground Control Points for Drone Imagery and test how they influence the Orthomosaic accuracy before and after using GCP by looking at the amount of error in the Adjustment Report. After setting up my Workspace using the OrthoMapping workflow (type Drone), I use the Adjust function to apply block… (Show more)

Just tried FMV with Arcpro 2.2.  Used the multiplexer to add MISB data to a video and got this error.   ERROR 002652: Unable to parse the header of the metadata file. Ensure each column in the metadata file corresponds to a legal MISB 0601 header, or that there is a corresponding entry in the metadata field mapping file.    I used the same… (Show more)

Than I used Data management / Clip. After that my clip image was all white so I… (Show more)

Hello - I'm using two tools, the "Create Orthocorrected Raster" and also the "Geometric" raster function to apply the RPC file for a WorldView 3 image and a high resolution DEM to orthorectify my image. The raster functions work great, I get an offset of ~1-3 pixels but they don't use nearest neighbor (NN) resampling which is imperative for my… (Show more)

Hello! I am working on a project where I am trying to detect the expansion of sugarcane crop area over time, using 10 m Sentinel-2 imagery. The area I am researching is about 460,000 acres. Currently I have approached this task a number of different ways. I have used the imagery difference tool for two images converted to NDVI. I have also… (Show more)

I have been struggling with this problem for some time - I am rather new to ArcGIS Pro and apologize in advance if this is trivial, but I really need to find out what I am doing wrong...   I have a set of Sentinel 2 images with just one band each (NDVI or NDRE) and a set of drone photos that are multispectral.   I used Extract Band to isolate… (Show more)

Hello everyone, a quick question regarding the functions available within the ArcMap Image Analysis window (10.5.1 for reference).   Is there a function that will replicate what I could achieve using the Focal Statistics tool with 'Minimum'? Effectively I would like to sample across a singleband image in a 11 x 11 neighbourhood and select the… (Show more)
