Can a shapefile be created from a table?
If a table contains information describing spatial locations, such as x,y,z coordinates or street addresses, you can create a shapefile representing those locations with tools available in ArcCatalog. In addition to shapefiles and tables, ArcView GIS users work with project files, legend files, and Avenue scripts.
How are geographic features represented in a shapefile?
Geographic features in a shapefile can be represented by points, lines, or polygons (areas). The workspace containing shapefiles may also contain dBASE tables, which can store additional attributes that can be joined to a shapefile’s features.
Where do I find attributes in a shapefile?
You can join attributes stored in a dBASE table or text file to the features in a shapefile in a layer’s Properties dialog box on the Joins & Relates tab.
How do I create a new shapefile in arc?
Creating a new shapefile. You can create new shapefiles in ArcCatalog or by using the Create Feature Class tool. When you create a new shapefile, you must define the types of features it will contain, whether those features will represent routes (m-values), and whether those features will be three-dimensional (z-values).
How to convert UTM coordinates to shapefile?
Click on Layers ‣ Add Delimited Text Layer. In the Create a Layer from a Delimited Text File dialog, click on Browse and specify the path to the text file you downloaded. In the File format section, select Custom delimiters and check Tab. The Geometry definition secction will be auto-populated if it finds a suitable X and Y coordinate fields.
Where do I find a shapefile in ArcCatalog?
Below is an example of how shapefiles appear in ArcCatalog. You can also see the dBASE file (that may be associated with a shapefile). All files that have the file extensions .txt, .asc, .csv, or .tab appear in ArcCatalog as text files by default.
How to merge multiple shapefiles into a single shapefile?
Question: I have multiple shapefiles of underwater forms (coral reef, outcrop, sandflat, etc) that I would like to combine into a single shapefile. This would make the data easier to manage and I would use a column in the attribute table to delineate each form, rather than have each be in a separate shapefile.
How are feature types converted to geometry types in shapefile?
All feature types in shapefiles convert to geometry types in the geodatabase. Unlike coverages, shapefile feature types are similar to the geometry types stored in a geodatabase, so conversion is more straightforward. For more information, see How data converts when importing. Each of the component files of a shapefile is limited to 2 GB each.
