EWMAPA

[PPU GEOBID]

EWMAPA - a computer graphic programme having a unique structure of data storage: base, vector, object.
 EWMAPA is a versatile programme which may serve the purpose of construction of digital maps, and servicing the geodetic and cartographic resources, as well as that of creating and analysing objects in space, on the basis of data contained in other modules of the STRATEG system.
 
 The system is based on a cadastral system of spatial references, that is border points, parcels, and classification contours. The layers and sub-layers in the system are of technical character as they serve the purpose of physical division of the content of spatial elements and creation of dispersed databases.
 Objects may be composed of elements located on different layers and sub-layers, they are of functional character. Descriptive attributes are most often associated with objects.
 
 EWMAPA provides various possibilities of data presentation, in the form of:
 
 . printouts of co-ordinates, surfaces, frontal measures
 . outlines on matrix, ink jet, and laser printers
 . outlines on plotters
 . hybrid outlines (raster-vector ones)
 . outlines with possibility of covering content (transparency)
 . raster image modelling in a continuous manner the attributes of two-dimensional space (including also the third dimension).
 
 The new thing is the use of colour raster and the possibility of transforming aerial photographs into orthophotograms, on the basis of land model constructed from height measurements (station poles) held in the geodetic and cartographic resources.
