Republic of Maldives
OneMap is the official national portal for geospatial, mapping, and land information, serving as the authoritative source for national maps and framework datasets managed by the Geomatics Department under the Ministry of Finance and Planning. The platform provides public access to standardized and trusted spatial data for use by government agencies, private sector, researchers, and the general public.
The portal offers downloadable national geospatial datasets and supports land administration, planning and informed decision making. Openly accessible geospatial data promotes transparency, supports innovation, reduces duplication of data collection, and enables consistent use of national spatial data. All datasets are maintained in accordance with national standards

Following UN guidelines for standardization and romanization of Dhivehi names
The Geomsatics Department follows the UNGEGN (United Nations Group of Experts on Geographical Names) system for romanizing Thaana script. This system provides a consistent and reversible method for converting Dhivehi geographical names to Latin characters.
Following international standards set by UNGEGN for geographical names
System maintains ability to convert back to original Thaana script
Compatible with all modern systems and international applications
Represents the actual pronunciation of Dhivehi words as accurately as possible using Latin characters
Each Thaana character has a single, consistent representation in the romanized form
Avoids complex diacritics and uses standard Latin characters accessible on all keyboards
The system allows for accurate conversion back to the original Thaana script when needed
Thaana consonants are transliterated following specific rules to maintain phonetic accuracy while ensuring international readability.

Retroflex 'sh' sound, distinct from the alveolar 's'
Retroflex 'l' sound, represented as 'lh'
Palatal nasal sound, represented as 'y'
Glottal stop, often silent at word beginnings
Thaana uses a combination of base characters and diacritical marks (fili) to represent vowel sounds. The romanization system accurately represents these vowel qualities.
| Thaana | Roman |
|---|---|
| ަ | a |
| ާ | aa |
| ި | i |
| ީ | ee |
| ު | u |
| ޫ | oo |
| ެ | e |
| ޭ | ey |
| ޮ | o |
| ޯ | oa |
Short and long vowels are distinguished (a vs aa, i vs ee, etc.)
ް indicates absence of vowel, represented by apostrophe in romanization
Combinations like 'ai', 'au' are represented as written in Thaana
Nūn used for nasalized vowels in certain contexts
How to properly implement the romanization system in mapping, addressing, and official documentation.
