uSMART Geodetic

Define and Utilise Geographical coordinates (i.e. Latitude and Longitude) together with Map Projections.
Convert between Map Projections.

Probably the most important fact is the way in which uSMART makes use of two individual conversions that can be chained together, namely "Map Projection to Geodetic" and "Geodetic to Map Projection". This means that map projections that can be related to a spheroid can be interactively and dynamically converted between them.

If, for example, it is required to convert from a Gauss conform projection to a UTM projection, the necessary parameters will be entered for each projection individually thus relating each to a spheroid. When a conversion is required, the routine will convert from the map projection of the one to Geographical coordinates and then from the Geographical coordinates to the other map projection. The user also however has the option of only doing the one conversion resulting in a conversion between map projection and Geographical coordinates in either direction.

Please note that it is not necessary to have different map projections for each conversion. It may, for example, be required to convert a Gauss conform projection from one panel to another. This requirement can be easily catered for by specifying (in the job configuration) a different "Secondary systems Central Meridian" to the standard "Central Meridian".

These conversions can be done on the fly. This means that any coordinates exported or imported to uSMART can be converted in the import/export process. The Geographical and "secondary" map projections coordinates can also be displayed and entered with a key-in dialog box. This effectively allows the user to view and input coordinates in three systems simultaneously.

A User Coordinate System may be setup which caters for virtually any transformation/projection required by the user. It allows the user to create a projection or to apply constants/multipliers to a projection. This means that final job coordinates can be different to the orientation ground coordinates as used in the absolute etc. For example, a cylindrical projection could be used to map an open cast mine.
