1. A method for creating a database for recording a railway line,
creating localized first measurement values using a first measurement location attribute of a first coordinate reference system, the first coordinate reference system being at least one of an absolute first coordinate reference system and a relative first coordinate reference system, the first measurement values comprising first measurement value attributes created by means of at least one of a first sensor and by a first input;
creating localized second measurement values using a second measurement location attribute of a second coordinate reference system, the second coordinate reference system being at least one of an absolute second coordinate reference system and a relative second coordinate reference system, the second measurement values comprising second measurement value attributes created by means of at least one of a second sensor and by a second input, the second coordinate reference system being different than the first coordinate reference system;
performing a coordinate transformation of the first coordinate reference system and the second coordinate reference system into a unified coordinate reference system, the unified coordinate reference system being different from at least one of the first coordinate reference system and from the second coordinate reference system, the unified coordinate reference system comprising at least one reference point, the coordinate transformation being performed by generating a unified measurement value set comprising at least one of the first measurement values and the second measurement values;
storing the unified measurement value set in the database, the first measurement value attributes and the second measurement value attributes being stored in the database in a defined structure in the unified measurement value set, the defined structure of the unified measurement value set comprising at least structured storing of the first measurement value attribute and the second measurement value attribute; and
controlling a rail repair machine traveling on the railway line based on the unified measurement value set stored in the database;
wherein the database comprises objects including rail, ballast, vegetation, groundwater, a rail cross-section, catenary, crossties, fasteners for attaching a rail to a crosstie, and catenary masts; and
wherein the first measurement values and the second measurement values form a measurement value set, the measurement value set describing one of a first condition of the railway line and a second condition of a vehicle traveling on the railway line, the first measurement values and the second measurement values being heterogeneous.
