Learn more about a dataset
While searching for data on Koordinates, you are able to learn more about individual datasets before adding them to the map.
Datasets on Koordinates sites come with a range of supporting information explaining the nature and history of the dataset and how it can be used.
The first interaction with any dataset on a Koordinates site will usually be the summary view provided on the left hand side of the screen. This view provides a concise introduction to the basic features of the dataset. Many of these are self-explanatory. Running from the top, these are:
- The title of the dataset
- The source of the dataset
- Date added and updated
- View and download count
- A button to add the dataset to your collection.
If you click on either the title or thumbnail of your chosen dataset, you’ll be taken to the dataset’s About page. This page gives a range of additional information about the dataset. Depending on the dataset you are viewing, the About page will provide:
- A general introduction to the dataset, which may include a statement about the dataset’s accuracy.
- The dataset’s licence.
- Information about how the dataset has been categorised and tagged, as well as its various metadata schemas.
- Technical details about the dataset, including its feature count, primary key and attributes.
- The history of the dataset, including when it was first uploaded, its latest changes and its revision history.
- Source code to embed the dataset.
Note that the revision history of the dataset is an automated technical history of the dataset generated by Koordinates so users can understand how up-to-date the data might be. It is not intended to be a meta-level history of the data.
The Metadata tab displays the metadata available for your chosen dataset. If the metadata is available in more than one schema, a dropdown menu on the right lets you choose which schema you want to see.
By clicking on the links in blue, we can also choose to download the metadata in either XML or PDF.
Select Data Table for your dataset to be presented as a browsable and searchable table.
The Data Table tab allows you to:
- Find specific data within the overall dataset, using the search box at the top of the data table.
- Remove the preview map - i.e. the map on the right half of your screen - so you can more easily view the tabular data. You can do this by clicking on the small arrow, and the map will disappear. You can find this arrow on the right margin of the table.
- Zoom to the point in the map that represents each individual row of data, by clicking the magnifying glass.
- Generate a link for each individual row, using the link symbol in the second column.
API and web services
If enabled for your chosen dataset, Services will list APIs and web services available for each dataset. This page provides brief instructions, and will link to documentation on the specific API or service in question.
