User Upload - Upload requirements
The following file types are accepted:
Comma Separated Values (CSV)
GeoJSON
Geopackage (GPKG)
Please note that uploading multiple data layers within one GPKG may result in unexpected behaviour when visualising the data on the map. We recommend separating the layers and uploading them individually.
Shapefiles
To be ingested successfully, files must meet the following formatting requirements:
Files must contain geometry attributes. Any rows which do not contain geometries cannot be shown
Point datasets are recognised in latitude and longitude formats. Where this is the case, the column headings should contain exactly the words “latitude” and “longitude”
Polygon datasets should be in WKT format or similar. For polygon datasets, the column heading should be “geometry”
If geometry and latitude and longitude columns are present, then latitude and longitude will be displayed by default
Geometries with EPSG: 4326 and EPSG: 27700 are supported.
All column headings should contain:
Only lowercase characters;
No spaces (spaces may be replaced with underscores);
No special characters (e.g. &*-@!#$)
Numbers should not have commas as delimiter e.g. 10,000 should written as 10000
Shapefiles should be uploaded as a zip
The zip file needs to contain all mandatory parts of a shapefile. This includes .shp, .shx, .dbf, and .prj files:
.shp files contain the geometric data (points, lines, and polygons)
.shx files contain the index of the geometric data
.dbf files contain the attribute data in tabular format
.prj files store the coordinate system info
User Upload - Transforming datasets
There are several open source, free-to-use tools available to help transform datasets into the required formats.
Note: Advanced Infrastructure is not affiliated with any of these providers and cannot guarantee the security of any data uploaded to third party websites.
Transform Shape files to GeoJSON or CSV formats: https://mapshaper.org
Convert X & Y into latitude and longitude: https://gridreferencefinder.com/
Convert Eastings and Northings and UK grid reference numbers into latitude and longitude: https://doogal.co.uk/
If you're struggling to transform a dataset, we recommend reaching out to any data specialists within your local authority, as they may be able to lend a hand.
Sharing your uploaded data
To share your dataset with all other users who have access to your Local Authority's instance of the platform, click the 'i' icon next to the dataset title, and select 'Share dataset with other users'.
To be more selective about who has access to your uploaded data, ask your local admin user to help manage the access permissions for your dataset. Instructions on that here.
