The demand for geoinformation is constantly growing, forcing data publishers to strike a balance between the art of map-making and the need to keep data and services up to date. The Geographic Institute of Spain(IGN) as a public institution is entrusted, amongst others, with creating, maintaining, and updating the State’s basic cartography at a 1:25,000 scale. At this scale, Spain is divided into 4.096 sheets, with an update frequency of less than a year. FME was used to create an automated workflow that starts importing data from a PostGIS database and through the most diverse decision-making methods ends up with a cartographic output symbolized in MAPublisher, obtaining GeoPDF files for each sheet, which are then made available for public download. Recently a new feature was added to this workflow: the publication of these sheets in COG (Cloud Optimised GeoTIFF) format, which allows for a great saving of disk space on the servers due to its high compression rate. This workflow is also being applied for the generation of topographic maps at a scale of 1:50,000.

Geographic Engineer
Since 2019 I’ve been working in the cartography
division of the National Geographic Institute of Spain
as an engineer.
In addition, since the same year I work in the
development of the automatic process of map
production with FME and Mapublisher.
Currently, the process is being modified to adapt it
to the production of the National Topographic Map
at 1:50000 scale.

Thanks to FME's ability to
automate processes, it is possible
to easily adapt the process to
produce a different scale, which is
very versatile for our institution,
being able to adapt the series of
maps to the production needs.
Just change the scale, choose the
corresponding tables and
connections and start producing.
Furthermore, this automatic map
production does not require any
human intervention for the
production.

Agenda
In this presentation, it will be shown how,
through FME, the automatic production of
maps becomes easier.
I will review 3 reasons why automation in map
production is essential today:
● Satisfying citizens' demand for information
● Speed in the implementation of
information updates of the territory.
● Fast response time to changes in the
territory for mapping production.

Problem Description
Here, we present the problem we will be solving today.
● How to synchronise changes in the territory with
the production of maps?
● How our maps could be made more efficiently?
● That you’ll show them how to solve

Describe the Solution
The problem is to strike a balance
between the changes that occur in
the territory due to the changing
reality and the representation of
them on the map, minimizing
production times and maintaining
quality standards like our map made
by traditional methods.

At the National Geographic
Institute of Spain, we are
concerned that the public
should have in their hands
maps that faithfully reflect
the territory and the changes
occurring in it thanks to
effective and efficient
production with FME.
