Map Features

When you read a map in Views, cartographic data is loaded as IlvMapFeature objects. A map feature is an object that represents cartographic data as it was read from its source file. It can be a segment of road, an aerial image, the summit of a hill, or a digital terrain model. A map feature carries the following information:

• The geometry of the feature

• Attributes

• The projection in which the geometry is expressed

  Projections are not covered in this section. For details, see Selecting a Target Projection and Map Projections.
