This is beneficial when the spatial data for an exploration project is in different coordinate systems.
Spatial objects in Maptek Eureka™ are initialised by the user to a coordinate system. Predefined grid coordinate systems include:
Users can also define their own grid systems by specifying a datum - a reference ellipsoid and a transformation back to WGS84 - and a projection system.
Objects in one coordinate system can be transformed into any other coordinate system.
A calculator tool allows users to check coordinate conversions and pick a point on a UTM grid to display latitude and longitude.
A geographic graticule can be created to provide a reference grid to help with the conversion.
Converting data is simple with Eureka. The user assigns an initial coordinate system to the objects, which can be transferred to other objects to ensure all of the data in the focus area is georeferenced correctly. The data can then be transformed to any other grid projection.
Setting the coordinate system to a local projection minimises distortion when the area of interest lies on the boundaries of standard UTM zones.
Eureka 1.1 is scheduled for release at the end of 2013. New functionality includes implicit modelling and interactive drillhole editing.
