How
to manipulate data?
In TerraView data can come from different data sources from where datasets can be selected and added to a
project becoming a project layer. A layer is then manipulated inside the
application. Several tools are available to manipulate data sources, datasets and layers. This session aims is to
give a quick index to the most used tools grouped by its
functionalities.
Tools to add/update/remove data
sources and select its datasets:
Tools to exchange data between
data sources:
Tools operating
over a Layer:
Tools operating
on data table:
Tools to set or change
the spatial reference system of a Layer or Map Display:
It also worth mention the different ways to obtain a layer and add it
to the application. A layer can represent the whole content of a
dataset stored in a data source, can be a query result, and also can
be generated from a tabular file (with or without geometry). The
details are given in the links bellow:
When a layer is added
directly from a directory of vector
or raster files, a new datasource is added to the list of Data Sources
available with the same name of the layer. Check all ways to
add a layer in Project
Menu.
