Onemap is the authoritative
source for the National map of Maldives developed and maintained by the Maldives Land and Survey
Authority under it’s mandate of creating the National Chart and maintaining the National land
registry.
The atoll Nation of Maldives is made up of more than thousand islands. An
island is defined as a piece of land (formed naturally or man-made) surrounded by water. If an
island is administratively subdivided, each separate piece of land will be considered as a
single island. If two islands are merged for administrative purposes, it will be identified as a
single island.
Islands are a type of feature in OneMap. The official names of features
together with their unique codes are identified in the map.
The island names are originally in Dhivehi language and has been converted to English under standardized transliteration criteria. More Info

Geographic names standards are important not only to prevent ambiguity and confusion in spelling of geographic names but also in fulfilling the needs of commerce and international relations, and it is the goal of United Nations to establish such standards among its members (United Nations, 2007). Standardization is concerned with written forms of names including their script, spelling, word forms, writing marks and capitalization. Standardization is also aims to establish a convention for names conversion which is the process of converting geographic names from one written script to another. Although the written forms of many languages such as English use what is known as the Roman (Latin) script, other languages such as Dhivehi are recorded using other non-Roman scripts.
There are two main methods known as transcription and transliteration that are used for names conversion. Transcription is the conversion of sounds of one language into the closest corresponding written sound symbols of another. However, it is always not possible to accurately convert the sound symbols of one language to another without adding special marks (diacritics) and/or letter. Conversion using such additional diacritics and/or letters is called transliteration. The intended sounds of diacritics marks and other symbols are not usually understood by most people and for this reason transcription is often adopted for more everyday situations, using only the letters and letter combinations of a target alphabet, at the expense of the exact original pronunciation.
The Roman script has been adopted as a base for international use by the United Nations and it is recommended that a single romanization (transliteration) system should be developed for each non-Roman script. Additionally the United Nations Group of Experts on Geographical Names (UNGEGN) recommends several factors that need to be considered when adopting a romanization system. They include:
Currently no romanization for Thaana has been approved at the United Nations conference on the standardization of geographic names. However many methods are used to convert the geographic names written in Thaana to Roman alphabet. Some use diacritical marks where as others do not. This lack of standardization has led to considerable difficulties in communication as well as data comparison. Hence a romanization system needs to be adopted for use in the cartographic works produced by the Maldives Land and Survey Authority (MLSA) and by considering the above factors recommended by UNGEGN, the following romanization system without diacritical marks will be used in writing geographic feature names.
The following is the System of romanization (transliteration) for Maldivian script, Thaana. Thaana is written from right to left. Vowels are marked as diacritical marks accompanying a consonant character.
A Romanized n’ if used without any vowel (Ex: ކަނޑު kan’du).
B Not romanized but see note 1.
Consonants with diacritical marks (used mainly in words of Arabic origin, corresponding Arabic characters and their romanizations are shown in parentheses)
Notes:
The Draw widget allows you to draw simple graphics and text on the map. You can also use it to add line distance or polygon area to the feature as text. This widget provides basic sketching and markup functionality. It also displays some measurements for drawn features, such as length for lines and area and perimeter for polygons. When the widget initially opens, a window appears that contains the following draw tools:
To get started with the Draw widget, complete the following steps:
The Measurement widget allows you to measure the area of a polygon or length of a line or find the coordinates of a point.
Click the Measurement widget icon to open it.
Click the Location button and click a location on the map.
The Measurement widget displays the coordinates for the point in degrees (decimal). To change the coordinate display format to degrees/minutes/seconds, change the selection in the Degrees drop-down menu to DMS.
The Measurement widget displays the total length of the polyline using the defined Default Length Unit. To change the length unit, select the applicable unit of measure from the Meters drop-down menu.
The Measurement widget displays the total area of the polygon using the defined Default Area Unit. To change the area unit, select the applicable unit of measure from the Hectares drop-down menu.

The Print widget connects the web app with a printing service to allow the current map to print.
The Distance and Direction widget allows you to draw lines, circles, ellipses, and range rings to visualize important information.
You can use the Distance and Direction widget to create lines, circles, ellipses, or rings.
The Distance and Direction widget allows you to change the way coordinates are displayed in the coordinate text box. The Format Input and Add Point tools are located by the Start Point and End Point for the line tab, and Centre Point for the circle, ellipse and range rings tabs.
You can edit the symbology of a line, circle, ellipse, or range ring. Each tab has a Symbol and label settings section that provides the option to change how graphics are displayed.
You can create lines using the Distance and Direction widget given a distance and bearing, from known coordinates, or by interactively selecting points.
Create lines from a given distance and bearing.
Use known coordinates to create geodesic lines.
Interactively create geodesic lines on the map.
You can create circles using the Distance and Direction widget from known coordinates, interactively, or from a given time and speed.
Use known coordinates to create circles using radius or diameter lengths.
Interactively create circles by clicking the map.
Create a circle to identify potential locations for moving objects using a centre point, time, and speed.
The Distance and Direction widget can create ellipses from either known coordinates or interactively.
You can use known coordinates to create ellipses.
Interactively create ellipses by clicking the map.
Interactively create range rings by clicking the map.
Create range rings using a set ring number and distance with the Distance and Direction widget.
Create range rings based on an origin and distance from the previous ring.
