# Image Anonymization in Esri ArcGIS Pro

### Introduction

This tutorial will guide you through the process of anonymizing personal information in your images stored in a ArcGIS Online Feature Layer, by using Celantur's **Geoprocessing Tool in ArcGIS Pro** to connect to [Celantur Cloud API](/cloud-api/getting-started.md).

The Geoprocessing Tool will fetch the original image attachments which have not been anonymized yet, send them to Celantur Cloud API for anonymization, and save the anonymized images back to ArcGIS Online.

### Prerequisites

Before you begin, ensure you have the following:

* [ ] A Celantur account (app.celantur.com)
* [ ] Esri ArcGIS Pro
* [ ] A Feature Layer with a custom `new_anonymized` field

### Steps

#### 1. Prepare Feature Layer in ArcGIS Online

1. On the ArcGIS page <https://celantur.maps.arcgis.com/home/content.html> click to `New Item` button and proceed with creation of `Feature Layer` (skip this step if you have an existing feature layer).
2. Then open that new Item, and open `Data` tab and select `Fields` sub-tab
3. Click to `Add` button (only if this field does not yet exist)
   * `Field Name`: `new_anonymized`
   * `Display Name`: `Is anonymized`
   * `Type`: `integer`
   * `Default Value`: `0`
   * Click `Add New Field`

#### 2. Add the Celantur Geoprocessing Tool to ArcGIS Pro&#x20;

1. Download the Celantur Geoprocessing Tool ([CelanturBlurringToolbox.pyt](https://github.com/celantur/celantur-arcgis-tools/blob/main/geoprocessing-toolbox/CelanturBlurringToolbox.pyt)) from <https://github.com/celantur/celantur-arcgis-tools/tree/main/geoprocessing-toolbox>
2. In ArcGIS Pro
   1. Switch to "Insert" ribbon
   2. Click "Toolbox" dropdown
   3. Click "Add Toolbox"
   4. Select and open the Celantur Geoprocessing Tool (.pyt file)
   5. In the "Catalog" pane, select "Project"
   6. Expand "Toolboxes" and "CelanturBlurringTool" in the tree
   7. Double-click the "Celantur Blurring Tool" script

#### 4. Anonymize images with Celantur Geoprocessing Tool

1. In ArcGIS Pro, open the Celantur Geoprocessing Tool and specify your Celantur App username (email) and password, as well as the Feature Service Layer containing the images you want to anonymize.
2. Click "Run" to start the anonymization process.
