The Institut Cartogr\u00e0fic i Geol\u00f2gic de Catalunya (ICCG)<\/a> is the regional mapping agency in Catalu\u00f1a and one of the largest mapping agencies in Spain. They are in charge of capturing, processing, and publishing imagery and imagery derivative data into their open data portal. Once a year, they fly over the entire region of Catalu\u00f1a to capture and deliver up-to-date imagery services. One of the goals of ICGC is to quickly process large building change detection workflows and the extent of their captured imagery. This blog article covers one of the approaches you can take to accomplish change detection using deep learning in ArcGIS. ICGC made the imagery services available for this use case.<\/p>\n

Change detection is a common workflow for most, if not all, mapping agencies. It is traditionally time- and resource-consuming, which presents a challenge in keeping basemaps up to date.<\/p>\n

Deep learning tools in ArcGIS and pretrained models available in ArcGIS Living Atlas of the World<\/a> can be a core piece in an end-to-end change detection workflow, and they can help your analysis and visualization results provide important insights.

This workflow shows how to overcome deep learning challenges and implement best practices. It is mainly focused on imagery management, how to improve a traditional deep learning approach, and how the multiple resolution approach can help you improve results.<\/p>\n

Imagery management<\/strong><\/h1>\n

Today, organizations are dealing with a large amount of data. This allows you to see an updated overview of what is happening\u2014for example, the areas of urban expansion or how much a city has grown in the last 10 years, among other questions. But having lots of data can also present a big challenge: how to manage and access this large volume of imagery.<\/p>\n

The first step of any deep learning workflow is data preparation and image management.<\/p>\n"},{"acf_fc_layout":"image","image":{"ID":2366902,"id":2366902,"title":"Imagery Management in ArcGIS","filename":"2-Imagery-Management.png","filesize":207107,"url":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/06\/2-Imagery-Management.png","link":"https:\/\/www.esri.com\/arcgis-blog\/products\/arcgis-pro\/geoai\/building-change-detection-in-the-region-of-cataluna\/2-imagery-management","alt":"Imagery Management in ArcGIS","author":"19291","description":"","caption":"Imagery Management in \nArcGIS","name":"2-imagery-management","status":"inherit","uploaded_to":2364712,"date":"2024-06-06 16:23:23","modified":"2024-06-06 16:23:46","menu_order":0,"mime_type":"image\/png","type":"image","subtype":"png","icon":"https:\/\/www.esri.com\/arcgis-blog\/wp-includes\/images\/media\/default.png","width":1153,"height":278,"sizes":{"thumbnail":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/06\/2-Imagery-Management-213x200.png","thumbnail-width":213,"thumbnail-height":200,"medium":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/06\/2-Imagery-Management.png","medium-width":464,"medium-height":112,"medium_large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/06\/2-Imagery-Management.png","medium_large-width":768,"medium_large-height":185,"large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/06\/2-Imagery-Management.png","large-width":1153,"large-height":278,"1536x1536":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/06\/2-Imagery-Management.png","1536x1536-width":1153,"1536x1536-height":278,"2048x2048":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/06\/2-Imagery-Management.png","2048x2048-width":1153,"2048x2048-height":278,"card_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/06\/2-Imagery-Management-826x199.png","card_image-width":826,"card_image-height":199,"wide_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/06\/2-Imagery-Management.png","wide_image-width":1153,"wide_image-height":278}},"image_position":"center","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"

ICGC\u2019s initial data included two sets of imagery for 2018 and 2022 in GeoTIFF format in 8 bits and 3 bands. Resolution was 0.25 meters and data size for the entire source was 110 GB, which is challenging if you need to share locally stored information across an organization.<\/p>\n

First, create a mosaic dataset<\/a> for each year collection for your imagery. These are used to manage, display, analyze, serve, and share imagery and raster data.<\/p>\n

You can share data with people inside or outside of your organization by creating a map tile package in ArcGIS Pro. This is recommended for deep learning with RGB band imagery you need to share. In this example, a tile package was created and uploaded to ArcGIS Online.<\/p>\n

By creating a map tile package<\/a>, you can reduce the size of the data, which allows you to share it.<\/p>\n

Now that you have prepared the data, you can get started with deep learning.<\/p>\n

Use deep learning with the traditional approach<\/strong><\/h1>\n

Once you have the data prepared, the second step is defining the approach that you will use. With Living Atlas pretrained models, you can achieve high-quality results and a reliable estimation of changes. Following this approach, you can avoid the need to train a model, which eliminates the steps of labeling, data preparation, and model training that involve imagery requirements and massive computing requirements.<\/p>\n"},{"acf_fc_layout":"image","image":{"ID":2366922,"id":2366922,"title":"Workflow using Pretrained Models from Living Atlas","filename":"3-Workflow-using-Pretrained-Models-from-Living-Atlas.png","filesize":340736,"url":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/06\/3-Workflow-using-Pretrained-Models-from-Living-Atlas.png","link":"https:\/\/www.esri.com\/arcgis-blog\/products\/arcgis-pro\/geoai\/building-change-detection-in-the-region-of-cataluna\/3-workflow-using-pretrained-models-from-living-atlas","alt":"Workflow using Pretrained Models from Living Atlas","author":"19291","description":"","caption":"Workflow using Pretrained Models from Living Atlas","name":"3-workflow-using-pretrained-models-from-living-atlas","status":"inherit","uploaded_to":2364712,"date":"2024-06-06 16:24:23","modified":"2024-06-06 16:24:33","menu_order":0,"mime_type":"image\/png","type":"image","subtype":"png","icon":"https:\/\/www.esri.com\/arcgis-blog\/wp-includes\/images\/media\/default.png","width":1118,"height":357,"sizes":{"thumbnail":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/06\/3-Workflow-using-Pretrained-Models-from-Living-Atlas-213x200.png","thumbnail-width":213,"thumbnail-height":200,"medium":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/06\/3-Workflow-using-Pretrained-Models-from-Living-Atlas.png","medium-width":464,"medium-height":148,"medium_large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/06\/3-Workflow-using-Pretrained-Models-from-Living-Atlas.png","medium_large-width":768,"medium_large-height":245,"large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/06\/3-Workflow-using-Pretrained-Models-from-Living-Atlas.png","large-width":1118,"large-height":357,"1536x1536":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/06\/3-Workflow-using-Pretrained-Models-from-Living-Atlas.png","1536x1536-width":1118,"1536x1536-height":357,"2048x2048":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/06\/3-Workflow-using-Pretrained-Models-from-Living-Atlas.png","2048x2048-width":1118,"2048x2048-height":357,"card_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/06\/3-Workflow-using-Pretrained-Models-from-Living-Atlas-826x264.png","card_image-width":826,"card_image-height":264,"wide_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/06\/3-Workflow-using-Pretrained-Models-from-Living-Atlas.png","wide_image-width":1118,"wide_image-height":357}},"image_position":"center","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"

Why adjusting parameters can be crucial to get better results<\/em><\/strong><\/p>\n

Usually, the better resolution the better results you will get.

After getting a detailed view of the process to reach useable building features extracted through pretrained models, you see there are many tools and parameters to keep in mind in order to reach acceptable results. ArcGIS supports tool development with ArcPy and ArcGIS Python API libraries so you can automate the entire workflow of extracting buildings at multiple resolutions and then performing the needed QA\/QC at once.<\/p>\n

This will allow them to go beyond GeoAI and gather additional analysis-driven insights of new areas of development, urban density, and more.<\/p>\n"},{"acf_fc_layout":"image","image":{"ID":2372582,"id":2372582,"title":"Deliver Insight with Post Analysis","filename":"Deliver-Insight-with-Post-Analysis.png","filesize":52330,"url":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/06\/Deliver-Insight-with-Post-Analysis.png","link":"https:\/\/www.esri.com\/arcgis-blog\/products\/arcgis-pro\/geoai\/building-change-detection-in-the-region-of-cataluna\/deliver-insight-with-post-analysis","alt":"Deliver Insight with Post Analysis","author":"19291","description":"","caption":"Deliver Insight with Post Analysis","name":"deliver-insight-with-post-analysis","status":"inherit","uploaded_to":2364712,"date":"2024-06-11 07:02:58","modified":"2024-06-11 07:03:07","menu_order":0,"mime_type":"image\/png","type":"image","subtype":"png","icon":"https:\/\/www.esri.com\/arcgis-blog\/wp-includes\/images\/media\/default.png","width":512,"height":126,"sizes":{"thumbnail":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/06\/Deliver-Insight-with-Post-Analysis-213x126.png","thumbnail-width":213,"thumbnail-height":126,"medium":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/06\/Deliver-Insight-with-Post-Analysis.png","medium-width":464,"medium-height":114,"medium_large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/06\/Deliver-Insight-with-Post-Analysis.png","medium_large-width":512,"medium_large-height":126,"large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/06\/Deliver-Insight-with-Post-Analysis.png","large-width":512,"large-height":126,"1536x1536":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/06\/Deliver-Insight-with-Post-Analysis.png","1536x1536-width":512,"1536x1536-height":126,"2048x2048":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/06\/Deliver-Insight-with-Post-Analysis.png","2048x2048-width":512,"2048x2048-height":126,"card_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/06\/Deliver-Insight-with-Post-Analysis.png","card_image-width":512,"card_image-height":126,"wide_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/06\/Deliver-Insight-with-Post-Analysis.png","wide_image-width":512,"wide_image-height":126}},"image_position":"center","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"
