Import & Customise Datasets

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 

Importing a dataset

  1. The dataset import feature can be found on the layers panel. To import a new dataset click Import dataset layer import_layer

  2. 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, .kml, ShapeFile (must be uploaded as a zipped file), and .csv

(If you're looking to use a format that is not currently supported, please get in touch)

Podaris does not support multipart geometries. Any such features will be flattened into single-part features automatically, with any attributes copied to the created features. 

  1. 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 data type (string, number or boolean). Click IMPORT to finish.

For large datasets connecting to an external GIS server is likely to provide better performance when editing and viewing your project. If you require any assistance, please contact support who are happy to help discuss the best ways to import data.

Using datasets

Here we can see polygon data from our imported dataset visualised in pink.

Clicking on a polygon will allow you to 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

Styling datasets can be achieved by clicking the cog icon cog next to the dataset layer that you wish to modify. The colour and appearance of points, polygons and linestrings can all be styled here.

Styling by attribute

The fill color of polygons, linestrings and points can be styled based on a dataset’s attributes.

This can be done by changing the fill type from Solid to By Value.

Doing this will bring up some extra settings:

  • Attribute - select the attribute that you would like to categorize your dataset by
  • Classes - specify the number of color-categorized groups you would like to split your dataset into for this attribute
  • Color Scale - select the spectrum of colors you would like to use to categorize by this attribute. The color scale reads left to right, with values from the attribute in the lowest class receiving the left-most color and values from the attribute in the highest class receiving the right-most color.

After clicking Okay, these styling changes will have been applied to your dataset.

Labels

From within the Labels tab, you can choose to use any text-type attribute to display on the map above each feature. 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. From there you can also change the style of the label.

Amending attributes

Clicking the cog icon cog next to the attribute that you wish to edit will allow you to change the attribute's type (string/number/boolean), default value, as well as manually populate a list of allowed values.
