Graphs must be constructed accurately and accoring to accepted rules. Vanishing bearing and body orientation data can be represented as dots along the outside edge of an empty circle. Three Monarchs flying south, then, would be represented as three dots under the circle, one directly beneath the other. And so on. This type of a graph will give you a clear visual representation of your findings that is often more telling than the tables used to collect the data initially.
Statistics are also a valuable tool for looking at data and giving meaning to it.
If you are familar with statistics, use the results of your analysis in your conclusion. The data that we have collected as a part of this project is well suited to GIS technology because it has a critical geographic dimension. GIS integrates common database operations such as query and statistical analysis with the unique visualization and geographic analysis benefits offered by maps. These abilities distinguish GIS from other types of analysis. Mapmaking and geographic analysis are not new, but a GIS performs these tasks better and faster than do the old manual methods.
