Some map properties edit the entire map view. These include the scale, limits, and coordinate system for the entire map and the symbol and line properties for features on the map. Individual symbols and lines can be changed, but these default properties control all of the objects that have not been specifically changed.
Map scale controls the size of a map on the printed page. This is accomplished by defining a correspondence between length on the map (in map units) and length on the printed page (in page units). For example, one mile on the map corresponds to one inch on the page. The map scale is set using the Scale tab in the Property Manager. The map scale for the X axis and the map scale for the Y axis can be set in unison (proportionally), or they can be set independently.
Map limits are defined as the X and Y extents of the map. When a map is first created, the map limits are set to the minimum and maximum X and Y coordinate values of the collars table used to create the map. You can accept these as the limits for the map, or you can specify custom limits using the Limits page. Custom limits are useful when plotting only a portion of a map.
The map coordinate system is the target coordinate system for the map. A coordinate system has a defined projection and datum. If some map layers are using a different coordinate system, the layer is converted to the map coordinate system. The map's Coordinate System is the new coordinate system that you want to use to project your X, Y coordinate data.
The line properties control the default look of all axes, and well selector lines.
The fill properties control the fill patterns of any polygons in the base map.
The symbol properties control the default look of all wells in the map.
The font properties control the default text for all labels and text in the map.
The Info tab contains the name of the source file and the number of any objects in the group.
