Preparing the shapefile
In order to import the shapefile as expected, the shapefile will need to meet the following criteria:
- The shapefile must contain only 1 layer - The tool loops through all polygons in 1 layer, so please remove all other layers
- Polygons must not have any holes/cutout areas - For example, a ring doughnut shape will be rejected
- The areas will need to be singular polygons rather than multiple polygons - For example, an area that contains 2 or more non-connected polygons will not be imported.
- The shapefile's attribute table must have a name column - please add this from within your GIS platform, then export your shapefile.
Please note: If you are unsure how to prepare the shapefile correctly, you may wish to liaise with your GIS team so they can provide you with a shapefile that meets the above requirements
Once you have created your shapefile, you are ready to begin uploading and importing your shapefile.
Here you will need to enter the term used in the shapefile that identifies the name-field for each area. For example, your .dbf file should have a column which contains the name of each area to import. You should enter the text you have used in the column header to identify it as the 'area name' column.
Please note: This name field is also case sensitive, so please double check before uploading/entering.
The following shows the .dbf file and name field column when opened in excel. In this example, when filling out the name field you will need to enter 'NAME'.
To upload your shapefile to Local Insight you will need to have your zipped shapefile ready.
Please note: The shapefile must include all of the following files: .shp, .shx, .dbf.
If the shapefile was originally created with more than required 3 files, you will need to include all of these in the zip file. Do not edit these files after exporting from your GIS platform
Click 'Choose File' and select your zip file on your computer.
Importing the shapefile
Top tip: Your areas will all be added to the category 'Uncategorised', so we recommend moving any areas you have here already into another category.
Once you have completed the above, you are ready to import the shapefile.
Clicking import will disable the button to prevent further submissions. It will then upload, check the file, and process the areas in your shapefile. This process can take around a minute to process 1000 areas.
If you have received an error and you're unsure as to what it means, take a look at our article Why has my shapefile import failed?
When will my shapefile areas be ready to use?
Once processed, you should receive a success message at the top of the screen. You will then be free to browse your custom areas to see your new areas added to the 'Uncategorised' category. As with normal custom area creation, see our guide to viewing data for your areas - the tool will aggregate data for these custom areas one by one.
