At this first video of the fourth module we will speak about the attribute tables of a GIS, and we will show how to manage the alphanumeric information of a vector layer.

As we told at the first module, about differences between GIS and CAD, at the Geographic Information Systems we can manage different types of alphanumeric information. For example, for a parcel we can add information about the owner, area, coordinates, date of the buildings… And we can make a query to get the elements with a concrete values (for example the parcels with an area higer than X squared meters).

That information will be very useful for our city council, to manage the information in an easy way.

At this module we will see hot to manage that information.

At the first module of the course you can find a frequent questions section about the course, and if you have any doubt or error using gvSIG you can consult this post:  https://blog.gvsig.org/2015/06/17/what-to-do-when-we-get-an-error-in-gvsig/

At the third module you can see how to install gvSIG to follow this new module, and you can find the cartography to use for this video at this link.

Here you have the first videotutorial of this fourth module:
