Data QC & Cleanup

June 15, 2017 | 8:30 - 4:30
Taught by:
TeachMeGIS Instructor
Errors in your data, whether in the attributes or in the geometry, cause real problems when creating maps and performing analysis. There are some types of errors that 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 for finding and fixing GIS data quality issues. The course covers both spatial data problems and tabular data inconsistencies and errors. The course also teaches data management techniques that help prevent future errors including 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.
