TNT Georeferencing Highlights:

• Georeference spatial objects that have no prior georeference information, or improve or replace existing georeference information

• Use reference objects (image, vector, shape, ...) in any coordinate reference system

• View reference objects in separate view or as overlays in main view

• Auto-register option automatically generates many georeference control points for an image using a reference image or on-line web tileset

• Auto-register provides choice of matching one or more image bands to reference

• Specify minimum allowed point spacing and maximum point residual for auto-register option

• Optionally set control point symbol colors to indicate residual value

• Control point labels turn on/off in view automatically according to view scale

• Snap control points to elements in a geometric reference object or to intersections of a virtual map grid

• Import GPS points as control points from GPX files

• Choice of several coordinate transformation models with varied complexity for computing control point residual errors

• View and enter map coordinates in alternate coordinate reference system

• Set up simple georeference for images with rows/columns aligned to map coordinate axes

• Set up implied georeference for geometric objects containing map coordinates

• Simultaneously georeference bands in a multispectral image with choice of displaying single band or RGB band combination

• Transfer georeference from higher-resolution to lower-resolution bands in a multispectral image

• Create 3D control points for displaying cross-sections and other manifold objects in 3D perspective views
