Abstract: The road dataset includes Access Roads, Dzongkhag Highways, Primary Highways, Secondary Highways, and Thromde Roads. These classifications are based on their functional hierarchy and administrative importance. The dataset was developed under the coordinate framework of CGI during the National Cadastral Resurvey Program (NCRP). Some portions were updated through digitizing using Google imagery, and topological corrections were applied to address overlaps with the National Highway. Topological corrections were made, especially to ensure proper alignment and eliminate overlaps with the National Highway. This dataset will be updated periodically, and the latest version will be uploaded when updated data is received from MoIT.
Purpose: The road network dataset is developed to provide accurate and detailed information on the classification and distribution of roads across Bhutan. This data is essential for effective spatial planning, infrastructure management, and sustainable development by improving connectivity, optimizing transportation networks, and supporting informed decision-making at multiple administrative levels.

Content Information

Coverage Description

Attribute described by cell values: The dataset provides a structured view of Bhutan’s road network, categorized by road type and administrative relevance. It was created using the CGI coordinate system under the NCRP, with selected sections updated through Google-based digitizing. Topological adjustments were made to ensure accuracy and resolve overlaps with national highways. Designed to support transportation planning and infrastructure management, the dataset will be updated as new inputs are received from MoIT.
