Hi all,

I am attempting supervised and object-based image classification using Arch Pro (V.3.2). Here are the steps I have followed:

I acquired Sentinel-2 imagery and combined bands 2, 3, 4, and 8 (10m resolution).

I performed image segmentation.

I created a classification schema.

I generated training samples.

However, when I attempt to classify using a support vector machine classifier, I encounter the following error:

ERROR 003436: No training samples found for these classes: Soil, Water, Impervious, Grass, Tress.

The table was not found. [VAT_Segmented_202407110934456475089_interIndex]

The table was not found. [VAT_Segmented_202407110934456475089_interIndex]

Failed to execute (TrainSupportVectorMachineClassifier).

Failed at Thursday, July 11, 2024 9:44:52 AM (Elapsed Time: 0.22 seconds)

(I have attached a screenshot of the error.)

I have tried several times but haven't been able to identify the cause of this error. Do any of you know what might be causing it?
