GIS applied to Municipality Management: Module 4.2 ‘Attribute tables (joining tables)’

At this second video of the fourth module we will continue speaking about the attribute tables, where we will show how to join the the alphanumeric information of a vector layer and an external table.

In our city council we can have external information in a table, and it would be interesting to georeference it, that means, to join the information of that table with the alphanumeric information of a vector layer.

For example, if we have a table with the population of each neighbourhood in our municipality, and we also have a vector layer with the neighbourhoods in our GIS, we can add the population of the first table to the graphic layer. For that we would need a field in both tables with common values. If we use the name of the neighbourhoods there can be different names (with or without the article…), so we can get an error. Then it will be recommendable to use a numeric field, where the numbers will be the same in both tables (we can use the neighbourhood code).

Here you have the second videotutorial of this fourth module:
