GeoDLL - геодезическое программное обеспечение для различных
платформ. GeoDLL содержит точные функции, которые может преобразовывать
в 2D и 3D системе координат, геодезическое изменение данной величины и
справочную систему преобразования, изменение полосы меридиана,
определение координаты и системы эталонов, системы вычисления
расстояния, Цифровую модель Возвышенностей, обработку NTv2, Прямые /
Обратные Решения и функциональные карты.
GeoDLL supports the development of geodetic software on various
platforms by providing geodetic functions. GeoDLL contains precise
functions of the themes 2D and 3D coordinate transformation, geodetic
datum shift and reference system convertion, meridian strip changing,
user defined coordinate and reference systems, distance calculation,
Digital Elevation Model, NTv2 handling, Direct / Inverse Solutions and
map function.
User coordinate systems, local reference systems and earth ellipsoids
can be defined, based on the coordinate system parameters, the semi
axes of the earth and seven Helmert or three Molodenski datum
parameters.
GeoDLL comes with extensive documentation and is supplied as a DLL file
or as C++ or CA-Visual Objects source code. The functions of GeoDLL are
suitable for multithreading. The DLL is written in the C++ language.
That gives very fast performance, compact code, and high stability in
use.
WINDOWS operating system allows building of function libraries intended
for use by applications, the so-called Dynamic Link Libraries. The
application uses functions stored in the DLL by making a DLL call. The
language used for developing applications that call functions of the
DLL is not important. It could be C++, Delphi, MS-Access, Visual Basic
or CA-Visual Objects or other. Therefore GeoDLL is delivered with
examples and interface source code for many commonly used programming
languages.
