MARPLOT®

rule

MARPLOT is the mapping application for LandView® IV. It is a separate program from the LandView database program. When you start LandView IV, MARPLOT is also started; thus you have two applications running simultaneously.

MARPLOT has its own set of help screens. Therefore, in order to obtain detailed instructions on using MARPLOT, choose Help from the menu bar in the MARPLOT application. You can also enter the MARPLOT program by clicking on the MARPLOT tab in the task bar.

The LandView IV product contains the 3.2.3 version of MARPLOT software. It has two new MARPLOT behaviors not yet documented in the MARPLOT Help.

  1. Selecting a single object in MARPLOT by Clicking. This fixes a bug where in certain situations the object on the bottom was selected rather than the object on top.

  2. Circle objects now represent approximate earth circles. Circles created with MARPLOT now represent a circle on the earth (i.e. they take into account the earth's curvature) rather than circles on the computer screen. This change means that large circles will appear on the computer screen as ellipses as one moves away from the equator.
