ERMapper Format

The ERMapper map format is implemented by Dinamica EGO as follows:

Maps are represnted using two different files:

The header file uses the extension “.ers” and stores the map metadata.

The data file does not use an extension and stores the cells from all map layers interlaced by lines. Compression is never used.

Due to format limitations, maps whose cells are represented using 1 bit per cell are written using 8 bits per cell, unsigned.

Blanks in layer names are automagically replaced by “_” (underscore) when reading maps.

It is not possible to read or write maps bigger than 4 Gbytes (4294967296 bytes) even on Dinamica EGO 64.
