Abstract
In the framework of development of the Atlas of the Main
magnetic field of the Earth (EMMF) a series of digital charts
of the Earth's magnetic field was developed with mapping of
parameters of the Earth's main magnetic field:
anomalous component and component frequency of
EMMF;
characteristics of EMF spatial structure and reflection of
variation cycles.
During developing of EMMF digital charts mapping projections
and scale were selected and established, primary
data (sources of information) were analyzed, applied for
developing of EMMF digital charts. Technology of mapping
of EMMF digital charts was developed according to the data
of observations' network and centers for collecting, storing
and processing data. The tasks of converting of data, data
evaluation and generalization were also solved.
At elaborating methods and technologies of EMF digital
charts professional toolkit and program software were used.
Digital charts were prepared on licensed program software
ArcGIS in raster and vector formats. A list of requirements to
EMMF charts description was prepared, economic evaluation of
alternative methods of EMMF study is carried out, technologies
for charts' editing, quality control and publication were worked
out.
Questions related to authorship at mapping digital charts are
being settled down.
