This document explains how to use the Map Simplification deep learning model available on ArcGIS Living Atlas of the World.
Digitization of old records is a crucial task for organizations worldwide, as it not only preserves valuable historical information but also enhances accessibility and usability. By converting physical documents into digital formats, organizations can better understand historical changes, improve record-keeping practices, and facilitate the upgrading of data infrastructure. This process is essential for maintaining the integrity of information while ensuring that it remains available for future generations.
This model can generate a simplified version of scanned images, including topographical maps, floor plans, and cadastral maps. It helps to simplify hatch patterns, reduce salt-and-pepper noise, and effectively separate background from foreground elements. By extracting higher-level patterns from the input imagery, the model enhances the clarity and usability of the data. During the image simplification process, the input images are converted to black and white, which helps in emphasizing the essential features and structures within the maps. This conversion is beneficial, as it streamlines the semiautomatic or manual digitization workflow.
License requirements
To complete this workflow, the following are the license requirements:
- ArcGIS Desktop—ArcGIS Image Analyst extension for ArcGIS Pro
- ArcGIS Enterprise—ArcGIS Image Server
- ArcGIS Online—ArcGIS Pro or Professional Plus user type
Model details
This model has the following characteristics:
- Input—Raster with red, green, and blue bands.
- Output—A simplified, black and white variant of the input 3-band image.
- Compute—This workflow is compute intensive, and a GPU with minimum CUDA compute capability of 6.0 and 8 GB dedicated VRAM or higher is recommended.
- Applicable geographies—The model is expected to work globally.
- Architecture—This model uses the MangaLineExtraction model architecture.
