GaiaCad is a CAD/GIS program.GaiaCAD can switch between the 3D view of the Earth and a Cartesian, Mercator or user defined projections GaiaCAD can display multiple Raster or Vector layers of data simultaneously, with unlimited number of GIS Objects Each country, river, lake and item of text on the globe is a separate object that can be selected/delete/edit with the mouse. GaiaCAD can plot points to a resolution of 1500th of a second of Arc, approximately one inch. You can add to any layer, objects like GIS Polygons, GIS polylines, One point GIS Objects (Circles, text, etc). You can capture a view of Earth to BMP file. You can load directly as layers, industry Vector files standard like: MapInfo *.MIF files and *.ESRI *.SHP *.E00 files. You can load to layers photo File (Bmp). You can load to layers Raster Maps File, Like ADRG, ADRI, DTED (U.S. Defense Mapping Agency). You can save/load any Layer to *.Lyr file format, You can save/load a View of Earth to *.Env file.GaiaCAD support projection like: Spherical, Cartesian, Mercator, AlbersEqualAreaConic, Azimuthal2Equidistant, AzimuthalEquidistant, BehrmannCylEqualArea, Bonne, CylEqualArea, Equidistant, Peters, Sinusoidal.GaiaCAD support Spheroid models like: iry1830, Australian1965, Bessel1841, Clarke1866, Clarke1880, Everest1830, GRS1967, GRS1980, Helmert1906, Hough, International1920, Krassovsky1940, SouthAmerican1969, WGS60, WGS66, WGS72, WGS84. |
