To understand what a layer catalogue is, let us break down a few concepts.
Layers are the means by which geographic datasets such as boundaries, point of interest(parking bays, restaurants, warehouse), and so on are displayed. You specify the dataset and labelling properties of a layer when you add it to a map.
You can use layers to represent specific features on the Earth’s surface. These could be,
Points can be used to represent parking bays, restaurants, warehouses and so on.
Polygons can be used to represent areas definition, city boundaries and so on.
On Locale, through this feature users can upload and create their own boundary definitions, areas of interest and so on. These files are displayed in the same map. We support two types of layers:
Polygon layers: For example, these could be area definitions of a city, locality and so on.
Point layers: For example, these could be parking bays, restaurants, pick up points and so on.
📍What kind of layers can be added on Locale?
The users can add two different types of layers:
✨Note: Multipolygon or multipoint means that there are more than one polygon/points in that file.
📍What are the different files that are supported while creating a layer?
On Locale, the users can upload files of two different formats:
GeoJSON: GeoJSON is an open standard format designed for representing simple geographical features, along with their non-spatial attributes.
Sample GeoJSON file
KML: Keyhole Markup Language is an XML notation for expressing geographic annotation and visualisation within two-dimensional maps and three-dimensional Earth browsers.
Sample KML file
Formats supported on Locale
Note: The files should contain only one type of feature. i.e it can either contain polygons or points but not both.
