Message HrzProtocol.VectorDataLayer

Defined in hrz/protocol/layer/vector_data_layer.proto.

id: uint32

sources: HrzProtocol.VectorDataSource[]

Sources of vector data, that are combined to make up the layer’s data. The first source is the primary source, and the others are secondary. The primary source defines the number and order of features. Data from secondary sources is joined to data from the primary source, and adapted if needed to match the primary source. Data can be joined in two ways:

• The simplest way is to take geometries and attribute values in the order they come from. Features from secondary sources can be deleted if there are more in the secondary source than in the primary source. Default (empty) features can be added if the secondary source has fewer features than the primary source.
• If both the primary and secondary sources have features IDs, data from the secondary source can be reordered to match the primary source. Features from the secondary source can be discarded if they have no matching feature in the primary source, and default (empty) features can be added if some features from the primary source have no matching feature in the secondary source. Feature IDs must be defined with the same attributes in both primary and secondary sources, for joins by feature ID to be possible. When this condition is met, joins by feature ID are automatically used.
