Remember to also use the Zoom and Pan tools to navigate within the workspace to help you mark points and trace features of the georeferenced base map you are referencing. Now in the ArcMap workspace click to set each vertex of the polygon you want to draw.

(At this point you will not have added any information to your shapefile, so nothing will appear in the workspace showing your shapefile.) Your Shapefile and maps you've added will appear as layers in the Table of Contents on the left hand side and will be displayed in the workspace. Use the 'Add Data' button to add the Shapefile you created in ArcCatalogue. Use the 'Add Data' button to add any georeferenced base maps or layers that you want to use as a reference for creating your Shapefile.Ĭlick this link to view a list of available georeferenced maps and layers.

You will learn how to do this in the follwing steps describing how to create and edit Shapefile features in ArcMap.Ĭreating Features and Editing a Shapefile in ArcMap. You add information to the Shapefile's database using the Shapefile's Attributes Table in ArcMap. When you add a field, choose what type of data it will contain by selecting a format from the Data Type column. Type in the Field Name column to add further fields for information you want to contain in the Shapefile's database. The Shapefile Properties window will open. Right click the Shapefile in the Arc Catalogue window and select Properties. This database is used to store data against each vector shape we create in our Shapefile. You now need to set up the database associated to the Shapefile.Your Shapefile should now appear as a file in the ArcCatalogue window. To finish creating your Shapefile click OK on the Create New Shapefile window. Once added, click OK on the Spatial Reference Properties window. The best one to choose if using our georeferenced maps or WMS layers is the British National Grid, OSGB 1936 (EPSG:27700).Ĭlick Add to add the coordinate system to your Shapefile. You can then browse through sets of predefined coordinate systems and choose the one you require. In the Spatial Reference Properties window, click the Select button. The Spatial Reference Properties window will open. To set the coordinate system click the Edit button. If you prefer, you can choose to leave this empty and specify it later. It is also possible to set up your shape file in a specific coordinate system.Polygon is often used to trace features on a map or mark boundaries. Polygon is used to draw vector areas on a map. Point allows vector points to be placed on a map to mark single locations.

The most common types to choose are either point or polygon.
