This page contains information on how to bring data into your AURIN portal session
After selecting your area of analysis, you now need to bring some data into your AURIN portal session to visualise, interrogate and analyse.
The Data panel (shown below) provides you with three options for selecting data. Each of these will be explained in more detail below
The first thing to note is that the number of datasets that are available to you when you open the Data Browser window is restricted by your area selection – the smaller the area that you select, the fewer the datasets that will be available within your session
There are many ways that you can filter and search for datasets within the data browser. You can do a Keyword search, limit your search to a specific level of aggregation or granularity, or limit to the organisation/data custodian that you’re interested in.
When you select a dataset (shown below), the dialogue box will then require you to select the attributes you want for the data. You can select all of the attributes by clicking the top left check box next to “Attributes” (in red box on image below). Additionally, you may be required to filter some of the specific attributes(in blue box on image below). The abstract for your data is provided in the top right of the Data Browser window (green box). as by year of collection, or age cohorts.
Once you have selected your dataset and attributes, you can click either Add or Add and Open. The former option will keep your Data Browser open, so that you can shop for more datasets, but it will not automatically retrieve your dataset from the custodian/source. You will still need to do this by clicking on the specific dataset entry in the Data panel later. The latter option will close your Data Browser window and automatically retrieve the dataset from the custodian/source
You will first need to upload either a zipped shapefile (.zip) or a comma delimited file (.csv), by browsing to the right directory on your computer
Once the data has uploaded, you will need to name the data and put an abstract (preferably with metadata details), and specify the level of geographic aggregation (Aggregation Level), and the attribute field which identifies each of the geographic units, features, or rows (Key). Once you have added the data that you wish to visualise, click the Add & Display button.
If your data is either a non-spatial table (such as the age group mappings required in the Age Aggregation tool), or a shapefile that doesn’t contain geometries which fall into the standard aggregation hierarchy, select Non Aggregated under Aggregation Level.
In addition to bringing in data from the the AURIN data sources, or importing your own data, you can also create your own geometry (vector) datasets within your session. These can be important, for example, for creating potential point locations where you would like to measure the walkability around. Clicking on the Draw button calls up the geometry toolbar (shown below), which contains a number of features for creating geometry datasets. These are explained underneath the image left to right.
- Draw Point: this option allows you to draw different points over your area, such as potential site locations for anlaysing walkability
- Draw Path: this option allows you to draw lines over your area, such as potential road corridors or street networks
- Draw Polygon: this option allows you to draw irregular polygons over your area, such as potential catchments or regions which don’t fit within the normal aggregation boundaries
- Draw Regular Polygon: this option allows you to draw a regular polygon – either a triangle, square, pentagon, hexagon or circle
- Draw Circle: this option allows you to draw a circular polygon on the map
- Draw Box: this option allows you to draw a rectangle of varying dimension son the map
- Modify Geometry: this option allows you to alter the vertices and edges of your polygons to change their shape
- Draw Hole: this option allows you to cut a hole out of your polygons, creating “islands and donuts”
- Select Geometry: this option allows you to select specific items from the ones that you have created
- Drag Geometry: this option allows you to move specific items around on the map
- Delete Selected: this option allows you to specific items that you have selected
- Delete all Geometries: this option allows you to delete all of the items that you have created
- Save Geometries as a dataset: this option allows you to add the dataset that you have created to your Data panel
- Close Geometry Editor: this closes the geometry toolbar
Viewing Your Data
Once your dataset has been loaded, it will appear in your Data panel (as shown below).
Clicking on the table symbol will bring up your dataset. There are a few features that are worth pointing out when you open up the data table (shown below).
- All of the AURIN datasets come with a disclaimer, shown in green above. Clicking the disclaimer button brings up this information (which usually includes the important Terms and Conditions for use of the AURIN datasets!
- There is an option to view the columns either with their human readable Titles (default) or the machine readable Names.
- You can sort your columns by clicking on the column name to sort it either Smallest ↔ Largest, or A ↔ Z.
- Additionally, you can see the metadata for the dataset by clicking on the Metadata button, shown in blue above. This will open up a new window, containing a suite of information about the dataset, its format, its provenance etc (shown below)
Once your data has been loaded into the Data panel there are some options available to you by clicking on the spanner icon to the right of the dataset. This will bring up a menu looking like the one below. These are explained further under the image.
- Show/Hide: The eye symbol brings up the data that you have selected in a separate dialogue box, similar to the table icon to the left of the data entry.
- Rename: This allows you to provide your data with a new name. This may be important if you have similarly named datasets and wish to be able to distinguish between them.
- Remove: Clicking this icon will allow you to remove your dataset from your project – you can also do this by clicking on the red symbol next to the spanner. It may be necessary to remove the dataset’s “participation” in other components of your project, for example if you have the data mapped or in an interactive graph
- Display on Map: Clicking this will display the dataset on the map. Note that this is not the same as producing a choropleth of the data – it simply brings up the geometries without distinguishing between areas based on values.
- Zoom to Extent: This will allow you to zoom to the maximum geographic extent of your data in the portal view.
- Select Extent: This will allow you to alter the boundaries of a bounding box on the map
- Edit: This allows you to remove certain columns from your dataset, which is then re-retrieved from the data custodian.
- Load/Reload: This tool re-retrieves the data from its custodian. This may be important if the data have been updated since you last viewed them, or if you have previously had difficulty contacting and retrieving the data.
- Metadata: This tool allows you to view the metadata associated with the data
- Download: These tools allow you to download the dataset to your desktop as either .csv or .json file formats, or as .shp if the datasets are non-aggregated or spatialised
- Edit Aggregation Level: This option allows you to specify that your dataset is at a different level of aggregation than you had previously specified. This is really only useful for data that you have uploaded yourself
