Errors in your data, whether in the attributes or in the geometry, cause real problems when creating maps and performing analysis. Certain types of errors are very common, such as misspellings in the attribute table and edges of polygons that should, but don’t quite, line up. This course is designed to teach ArcGIS techniques to find and fix GIS data quality issues. It also addresses spatial data problems and tabular data inconsistencies and errors. Importantly, this ourse teaches data management techniques to prevent future errors such as setting up topology rules on your data to identify errors in the digitizing of data and using domains to prevent typos in your attribute tables.
