This blog post will give you a brief hands-on experience with the Image Classification Wizard in ArcGIS Pro 1.3.\u00a0<\/em><\/em><\/p>\n

Image classification is the task of extracting information classes from a raster image. The results of an image classification can be used to create thematic maps, analyze landcover, examine spatial relationships and more.\u00a0For example, if you have aerial imagery of some land that includes farmland, forest, ponds, and a city, you could assign a range of pixel values to each of these landcover types, classify the aerial images, and create a series of maps that display the change in landcover over time.<\/p>\n

Image classification is an incredibly useful and important task, but it can also be time consuming, complicated, and difficult to produce accurate results. Luckily, with the release of ArcGIS Pro 1.3, a magical new wizard has appeared to help you with your work.<\/p>\n

The Image Classification Wizard provides a simplified user experience comprised of best practices to guide beginning and experienced users through the classification process.<\/p>\n

Try your hand at the wizardry with this quick tutorial, or check out this help topic<\/a> to learn more about the Image Classification Wizard.<\/p>\n

It is recommended that you have some background knowledge of image classification to understand the terminology used in this blog. If you’re just getting started with imagery, check out the new ArcGIS Imagery Book<\/a>\u00a0filled with great interactive examples, videos, and exercises.<\/p>\n

Set up ArcGIS Pro 1.3<\/h1>\n
    \n
  1. You’ll need to have ArcGIS Pro 1.3 installed on your machine. The\u00a0post announcing the 1.3 release<\/a>\u00a0provides guidance on that. See the Get ArcGIS Pro 1.3 section.<\/li>\n
  2. In order to use the Image Classification Wizard and complete this tutorial, you must have an ArcGIS Desktop license (any level) with the Spatial Analyst Extension<\/a>.<\/li>\n
  3. Download the zip file<\/a> from ArcGIS Online that includes the ArcGIS Pro project and associated data. Extract the data to a convenient location on your machine.<\/li>\n
  4. Browse to the folder location where you extracted the files, and double-click ImageClassificationWizardTutorial.aprx to open the project.<\/li>\n<\/ol>\n

    Start the Image Classification Wizard<\/h1>\n

    Your project contains a number of raster imagery datasets on Lake Pontchartrain in New Orleans. These remotely sensed images contain data in red, green, and blue bands.<\/p>\n

      \n
    1. Click Imagery<\/strong> Layer<\/strong> in the Contents<\/strong> pane. The Raster Layer<\/strong> contextual tab appears.<\/li>\n
    2. Click the Data <\/strong>tab.
      \n

      \"Data<\/a><\/p><\/blockquote>\n

      \u00a0<\/a><\/li>\n

    3. On the Data <\/strong>tab, in the Image Classification <\/strong>group, click Classification Wizard<\/strong>. The Image Classification Wizard <\/strong>pane opens.
      \n

      \"Configure<\/a><\/p><\/blockquote>\n<\/li>\n<\/ol>\n

      Complete the classification<\/h1>\n

      In the map view, the raster landcover data for Lake Pontchartrain is useful for those who understand what the different colors of the RGB band combinations represent. However, if the image was classified, different landcover classes become apparent to anyone looking at the map. The Image Classification Wizard walks you step-by-step through the classification process.<\/p>\n

        \n
      1. On the Image Classification Wizard <\/strong>pane, on the Configure<\/strong><\/a> page, set the following configuration and then click Next<\/strong>:\n
