This repo is used to share materials including map or nonmap images used in our paper to reviewers of AAG Annals.

Images for computational cartographic recognition training and testing

Images in this repo are used to train and test machine learning models for identifying maps and for recognizing geographic regions and projections on the map. These images are stored in different folders that are organized for the three purposes. The folders and images are summarized below. Online maps and images vary significantly in their sizes. For example, in the category of world maps for region recognition, the sizes range from 315x160 to 4096x2906 pixels, and maps for China vary from 283x178 to 2250x1447 pixels. Maps in the syntheticMaps folders are generated using Python. These are supplementary maps for training and testing. Their size ranges are listed below.
