Magnetic map (K. Šalanský, 1995) of the Czech Republic in a scale 1 : 500,000 (GEOCR500) in the izanomal T (Z) form. Selected basic interval of isolines of 25 n T represents sufficiently accurately the course of the magnetic field. The map si complemented by the list of reports where are noticed basis which were used for the preparation of magnetic maps. The map is complemented by the selection of literature for interpretation of magnetic anomalies.
