Most users are comfortable with static 2D data, where a shape is represented on a surface and is invariant throughout time.
While most maps are built with this type of data, GeoServer offers you the possibility to explore even the third spatial dimension, which is elevation.
Besides, GeoServer can also publish data that changes over time. In this recipe, we'll see how to use data that changes over time using a set of points mimicking the path of a vehicle on a highway.
For this recipe, we need some new data. We will create a new dataset on PostGIS with data simulating a vehicle tracking path. It contains a set of points using timestamp.
First, we need to create a repository for the data. Execute the following SQL code to create a table:
CREATE TABLE vehicletrack (
gid integer NOT NULL,
"time" timestamp without time zone,
geom geometry(Point,32633)
);
CREATE SEQUENCE vehicletrack_gid_seq
START WITH 1
INCREMENT BY 1
NO MINVALUE
NO...
