Kiribati is located in Oceania, spanning over 3.5 million km², mostly sea. The landmass is only about 811km². There are 32 atolls and 1 separate island. About 100000 people live there. What is somewhat important for mappers: Kiribati may be the first country to disappear due to sea level rise.

Villages and maneabas
The heart of any Kiribati community is itsor meeting house. The maneaba is not just the biggest building in any village; it is the centre of village life and the basis of island and national governance.
There are also church maneabas that belong to its corresponding church, that are usually near to each other. And there are sometimes maneabas inside the schools.
A traditional maneaba is an imposing structure, with slabs of coral supporting a huge roof formed from coconut wood, held together with coconut string and thatched with pandanus leaves. The whole community is involved in its construction, and every aspect of the maneaba has a symbolic as well as a practical function.
But nowadays, many maneabas are constructed with concrete, and the roofs with corrugated metal.
Mapping a maneaba from aerial imagery
Spotting a maneaba when using imagery is normally easy, as you will see a big rectangular building that seems to have an inner roof inside the outer roof. This is due to the way the entire roof is built, as you can see in the image above. Be aware that many maneabas are nowadays built with industrial materials, using corrugated metalic material for the roofs.
Following is a collection of different maneabas around the islands of Kiribati:
Tagging of maneabas
As they are centres of a village life, maneabas should be tagged as:
- name=* (in case you know it. Please, avoid name=maneaba)
- operator=* (in case you know who operates it)
All islands in Kiribati are coral atolls. A coral atoll is a coral reef including a coral rim with cays (sandy islets) that encircle a lagoon. Some atolls in Kiribati don't have lagoon (like Arorae and Tamana in the Gilbert Group). But the majority of atolls do have a lagoon, that usually connects with the coral rim through the spaces between the islands and islets that conform the atoll. Some atolls like Kiritimati (Christmas Island) have one or more lagoons that are completely surrounded by land.
Some of the islets and islands are connected each other through bridges or causeways.
For the tagging of an atoll we will consider an atoll that has a lagoon conected to the sea in different points, and a completely enclosed lagoon inside one of the islands of the atoll, with a small islet inside it. Islands have beaches, forests and residential areas.
The proposed tagging of the whole atoll would be as follows:
- Trace the coral reef, and tag it as
- If there are parts where there is no reef, that means, stretches where the open sea enters freely to the lagoon, just connect one end of the reef with the following with a line.
- In case the reef surrounds all the atoll in one single line, add the following tags to the reef:
- In case the reef consists of several lines, put all of them and the connecting lines between them in a relation:
- The perimeter line of each islet or island would be tagged in general as:
- name=* Name of the island or islet
- Remember that the coastline has to be traced with the sea to its right.
- But to properly trace beaches, forests, residential areas, etc, we have to do it using multipolygon relations.
- This means we will have to cut the coastline in several parts, unless a beach or forest surrounds all the island. If you do that, move the place=island and the name=* to the multipolygon defining the whole island and listing all coastlines as its members with role outer.
- Then, we collect all the lines of the coastline in one relation, as follows:
- place=island or place=islet
- name=* Name of the island in its original language, if you know it
- Needless to say, the members of the multipolygon have to be all the parts of the coastline that conform the island, with role outer.
- With this tagging schema, we can now reuse any parts of the coasline for beaches, forests, etc.
- For a beach, it would be a relation like this:
- Finally, a lake inside one island should be tagged as:
- natural=water or
- natural=wetland, depending on what it is.
- If you have an islet inside that lake, then you would have to map it as a relation of type=multipolygon, with the perimeter of the lake as role outer, and the perimeter of the islet as role inner.
