3.1. The MID file

3.1. The MID file
	Chapter 3. Geometry input

The MID file must be made of only one column where territorial units identifiers are listed, one per line, without any doublon. Example:

"AT111"
"AT112"
"AT125"
"AT126"
"AT127"
"AT13"
"AT211"


	The given order of TU identifiers in the `MID` file must match the order of provided regions in the `MIF` file, see Data section of the MIF file

Based on a naming convention of the identifiers for these territorial units, following exceptions are handled by HyperAtlas for particular display options. Please take into account the following exceptions when designing your dataset:

FR, ES, PT, MT is the list of units identifiers for countries that own overseas units: France (Martinique, ...), Spain (Canarias, ...) and Portugal (Madeire). For example for European datasets, In HyperAtlas, the islands will be drawn in squares over the Russia.
SUR and BRA (Surinam and Brazil) are examples of units identifiers that are treated differently when drawing them on the maps by HyperAtlas.
Integer identifiers from 0 to 9 correspond to squares that must be drawn on the map, they are used for overseas in Europe dataset.
A territorial unit with the identifier no data will be painted in white on the maps that are drawn by HyperAtlas. This exception is used for North Cyprus in Europe datasets.
The chypre identifier is used to handle the particular case of the display of Cyprus island in the ESPON datasets.
