Once you have data in an existing table, feature class, shapefile or attributed relationship class, you can create attribute indexes for the fields you frequently query against. Ideally, you want to create indexes on columns with unique or almost unique values. Create only those indexes you reall...
Stellen Sie sicher, dass ein Shapefile oder eine Feature-Class nur von einem Benutzer bearbeitet wird. Wenn sich das Shapefile oder die Feature-Class in einer Anwendung befindet, die nicht mehr reagiert, beenden Sie den Prozess, um die Sperre aufzuheben. Nach dem Aufheben der Sperren...

. The output data can be converted to a simple shapefile, as well as a geodatabase feature class. If only features from a specific Layer or Level from the CAD file are required, Select by Attributes can also be used in ArcMap. After the required features are selected, right-click the ...
synthesized data. The original formatting of the raw datasets varied greatly. 62% were vector data (51.5% shapefiles, 3% KML/KMZ files, 7.5% feature class), 19% were raster files, and 19% were only available in tabulated format (comma-delimited text or Microsoft Excel files). In terms ...
