Edited data and created versions of data as edits were made, the positions of points, the size and shape of polygons and metadata for many features in the dataset. ● Used many of the ArcMap tools integrated into the software to analyze the data, and I validated the data to make sure that the data was in line with what was expected.● Change management was at the core of every function. I kept archived versions of all data; in case it was needed later for auditing or other purposes. Change management in ESRI ArcMap was done by saving different versions of mixed documents, as well as saving different versions of geodatabases, and assigning different names to the different versions. ● Extracted data for various business partners from databases using SQL queries. Also used query builder and model builder tools in ESRI ArcGIS software to provide data used in coverage analysis requests.
