How to do supervised and unsupervised classification in ArcGIS?

For supervised classification, the signature file is created using training samples through the Image Classification toolbar. For unsupervised classification, the signature file is created by running a clustering tool.

How do you do supervised classification?

When you run a supervised classification, you perform the following 3 steps:

Why is my ArcGIS not working?

If the layers in your ArcGIS Server service or hosted web layer have been reordered, removed, or the schema has changed, maps or layers referencing the service or layer may not function as expected. To resolve the issue, remove and re-add the service or layer and reconfigure the layer settings.

Which is better supervised or unsupervised classification?

While supervised learning models tend to be more accurate than unsupervised learning models, they require upfront human intervention to label the data appropriately. For example, a supervised learning model can predict how long your commute will be based on the time of day, weather conditions and so on.
 

Why is classification supervised?

Based on training data, the Classification algorithm is a Supervised Learning technique used to categorize new observations. In classification, a program uses the dataset or observations provided to learn how to categorize new observations into various classes or groups.

What is supervised document classification?

Supervised document classification



Supervised methods require a training data set with labeled documents to predict the category of new documents accurately. Conceptually, supervised methods attempt to find a relationship between the document and its category by looking at labeled historic data.
