1 、 Task of the Research

Design and development of the Xiamen Atmospheric aDesign and development of the Xiamen Atmospheric and Oceanographic Data Management and Visualizationd Oceanographic Data Management and Visualization System (AODMDS)n System (AODMDS)

Design and implement an effective representation and storage of oceanic and atomospheric data.

Design and implement based-ArcGIS, effective visualization and mapping of oceanic and atmospherics data.

Device some control to enlarge the functions of ArcGIS to provide the users mapping of gradually changed color

Solve the editing of annotation on the graph

2.Critical Technology Schema

AO-GIS Component Development Schema

Using ArcObjectsthe Development Methods ：

VBA development

Creating the users’s own COM

Develop a independent application program

-System is using VB+AO developing independently-Control is made by VC

3.Editing of Annotations

Annotation editingsIn ArcGIS ， Map labels can not be edited directly,

So an annotation layer is created so that

they can be edited.

Selecting text

Create Annotation
