The digital data was generated from the Geographic Information System of the Railroad Commission of Texas. Base map information was obtained directly from U.S. Geological Survey 7.5 minute quadrangle maps. Patent Survey lines from Texas General Land Office maps were interpreted as accurately as possible over the US Geological Survey base. Oil and gas well data or pipeline data (if included) was obtained from public records at the Railroad Commission. The information provided by this system is being continually updated and refined. The data is intended solely for the internal use of the Railroad Commission, which makes no claim as to its accuracy or completeness.Field Definitions can be found at: https://rrc.texas.gov/media/kmld3uzj/digital-map-information-user-guide.pdf

Dataset of 2Kx2K image tiles cropped from Taiwan Historical Maps System for the ICDAR'25 Competition on Historical Map Text Detection, Recognition, and Linking.

This collection contains topographic maps related to Taiwan, covering detailed records of the terrain, topography, and geographic names (in traditional Chinese).

Annotations and images follow the format described at the competition website and can be evaluated using the official evaluation repository script.

Please note the we also provide an extra synthetic dataset in traditional Chinese for training, which is released under the record: "SynthMap+ (Traditional Chinese) Synthetic Train Data for ICDAR'25 MapText Competition" (10.5281/zenodo.14502179).
