In this paper we describe the characteristics of magnetic first and second order networlts, the magnetic measurements and the data elaboration procedures. We report the new repeat station information and data reduced at 02,, hours for the day of measure and at the epoch 2005.0; we determined, for all elements, the coefficients for normal fields at 2005.0 and for secular variation in the period 2000-2005. The new maps for Italy, for D, F, H and Z at the year 2005.0, drawn with graphic contouring programs, together with a short explanation, are enclosed to this paper. In order to get an immediate inspection of magnetic element values in the area of interest on a PC an information system based on a CD program, is also enclosed.310 36 - PublicationRestrictedItalian Magnetic Network and Geomagnetic Field Maps of Italy at year 2010.0(Istituto Geografico Militare, 2012)

In this paper the procedures for magnetic measurements and data elaboration are described. Furthermore, for all the repeat stations data reduced at of the measurement day, at the epoch 2010.0; are presented. At the same epoch the coefficients for normal fields were determined for all the data, in order to draw the new maps of the geomagnetic field elements (D, H, Z and total field F) at the year 2010.0, at 1: 2 000 000 scale. All these maps were created by mean of interpolation procedures on GIS platform.319 64
