Data Editing and Topology
During the data creation, either using a tablet or on-screen, digitizing can generate errors. The error can be due to human error, such as missing a point, line, polygon, or digitizing extra features. Errors can also be generated during scanning, tracing or during the geo-referencing. An ArcGIS user can edit various types of data such as: feature data stored in shapefiles, geodatabases, and different tabular formats. The editing can include points, lines, polygons, and text.
