Integrated System of Cadastre Administration
Municipio de Tampico
Municipio de Tampico’s project was part of a
broader program to improve government and its
services. The goal was to reengineer administrative processes and introduce modern information
technology to help government better meet the
needs of its citizens.
One area of particular concern was cadastre
administration. This function has a direct impact
on not only future infrastructure development, but
also on the ability to assess property values and
collect taxes. Because it lacked a GIS solution,
the municipality was forced to rely on outdated
maps and manually acquired information, much of
which was incorrect. As a result, its database was
only about 30 percent complete.
With the implementation of its integrated cartographic system, Municipio de Tampico became
the first municipality in Mexico to take advantage
of 3D technology for cadastre administration. The
project involved photogrammetric flights, a door-to-door census, verification of existing parcel information and comparisons with new information,
and the incorporation within the database of
roughly 90,000 properties. As a result of this effort,
the municipality can now quickly identify all construction types within its boundaries and detail the
public services available within each zone.
Using MicroStation GeoGraphics and Bentley
PowerMap, Municipio de Tampico found it easy
to integrate topographical information from the
digital terrain model with cadastral financial information. MicroStation GeoGraphics has all of the
tools needed to quickly and efficiently search all
of the data, and is totally integrated with the existing systems used by the municipality.
The planned return on investment from this project
was about 12 months, but the new system paid for
itself in less than six months. A substantial portion
of the return came from an eight percent increase
in property tax collection, which resulted from the
detection of more than 15,000 residential and commercial building structures omitted from the previous database.
In addition, the public is enjoying increased
administrative efficiency. In-person customer service time has decreased from three hours to 20 minutes, and the time required to arrange for a physical inspection of a property has dropped from
three weeks to a week or less. ;
