Hi, I am attempting to create a training sample schema for an image classification in ArcPro. I created my own training samples in the form of a file geodatabase feature class and am attempting to upload that feature class into the training sample manager. When I select the "generate from training samples" options in the drop-down menu I get an error message that reads "Failed to generate classification schema from training samples", however, there is no explanation as to what went wrong or how to correct the issue. Does anyone have any suggestions as to how I can fix this? Thank you. ... View more

I am a masters student working with LIDAR and 4 - band satellite imagery to remotely measure above ground biomass of the shrub community encroaching the Illinois Lake Plain region. I am new to working with LIDAR data, and I am contemplating if creating an LAS dataset is necessary or if I should just import the LAS files directly. When working with LAS datasets, if you reclassify a point, will the classification change be reflected in the LAS file or will you have to do that separately?   ... View more

Spatial cover breakdown question: I have a shapefile of landscape characters (polygons) and a shapefile of land cover classes (polygons). Both are of the same region, i.e. they overlap. Is there a tool to obtain a breakdown of the spatial cover of all land use polygons within each landscape character polygon? Ultimately, the result would be a table with landscape characters as rows and the land use cover breakdown in columns. I have tried Clip, Union and Intersect, but the problem is new polygons are being created each time, rather than preserving the original landscape character shapefile and examining the cover of land use within. Any ideas are very welcome, many thanks in advance. ... View more

I am trying to classify thermal imagery using object based image analysis using Random Trees and Maximum likelihood classifiers. I was wondering if there are rules for how many training samples we should generate per class? ... View more
