Podaris allows you to import custom datasets and visualise the geographical features described within. These features may comprise points (useful for describing addresses or locations), line strings (suited to streets, highways, etc...) and polygons (ideal for describing tracts of land).
Importing a dataset
The dataset import feature can be found on the layers panel. To import a new dataset click Import dataset layer
Datasets can be uploaded from a local machine or by pointing to the URL at which they are hosted. Podaris currently accepts the following file formats for datasets: .geojson, .json and .csv
(If you're looking to use a format that is not currently supported, please get in touch)
- Once your dataset has been uploaded, you can choose which attributes to import by ticking or unticking each attribute's import checkbox and assigning them an appropriate datatype (string, number or boolean). Click IMPORT to finish.
Here we can see polygon data from our imported dataset visualised in pink.
Clicking on a polygon will allow you view (and change) all associated attributes, as well as view its perimeter and respective area.
In order to move this polygon, click once to select it and then again and drag it to a new location. Double clicking will allow you to manually edit its coordinates.
Styling datasets can be achieved by clicking the cog icon next to the dataset layer that you wish to modify.
The colour and stroke values of labels, polygons and linestrings can all be styled here. In order to set the attribute that will be visible as a layer next to each geometric element, select your preferred text attribute from the Labels box.
Clicking the cog icon next to the attribute that you wish to edit will allow you change the attribute's type (string/number/boolean), default value, as well as manually populate a list of allowed values.
