Overwrite Data?

When importing a series of files, it is possible through an error in specifying the time stamps, or perhaps because there is conflicting information in the file set, that two sets of data could apply to the same point in time. When you import data into SpaceStat, you need to define how to handle overlapping time stamps. The choices are:

• Do not merge data with the same name (uncheck "merge data with existing datasets by name"). This allos both sets of data to be viewed in maps, tables, and graphs.

• Merge data with the same name (check the "merge data" option) but retain data already imported (uncheck "new data takes precedence..."). This allows the new dataset to only be applied where there is no data for that time and for those variable names already in the project.

• Merge data with the same name but overwrite old information with new data (check "new data takes precedence...").

For shapefiles only, you will also have the option to overwrite objects (location, size, shape....) when overlap occurs. Again, you must choose whether the geography already in the project or the new geography you are importing takes precedence.
