A: Data Quality stems from the ability to provide trace-ability, integrity, spatial resolution, so forth. These can be achieved in several ways. For example through data input forms that check the values that are added, triggers can be enforced in a database to do automatic consistency checks, direct connection to other databases like AIXM ones might be done, availability to ingest different formats directly without user input like the ones provided by surveyors, visual and logical checks among others. Those are just a few besides the methods and procedures.
Specifically for using the GIS in a charting context you must ensure that any process you use can retain trace-ability in the production process. And repeat-ability when defining charts. This means careful content management and integration with a content management system may be required, depending on the complexity of your AIM department and existing systems.
