capture of the GPS coordinates of the supervisor's route, a high precision was
obtained, because its visual representation is very consistent with the shape of
the covered areas, with an average error of 3.8 meters. This method
guarantees that the supervisor effectively made his route in the areas of his
workload; this information also allows to determine the time invested and the
direction of the path.
Among the main areas of opportunity, in computer science, the need was
determined to implement laboratories to perform code testing and the use of
best practices for the development of applications for MD with Android
operating systems; the need for a tool for the remote erase or reset of the MD
was also detected for the cases of robbery or loss, as well as the remote
updating of the applications; in addition to the implementation of a more
robust security scheme, mainly in mobile devices and in the transfer of data to
the central repository.
Later, with the purpose of emulating in all the senses the activities of the
Census, the Pilot Test of the Population and Housing Census 2020 was carried
out, with a sample of more than 44 thousand dwellings and a duration of 20
working days. The installed offices corresponded to a municipal coordination,
that is to say, one of the around 1,600 offices in which the national territory is
divided for the gathering of information. All the planned operations were
carried out, including the post-enumeration and the special operation for the
enumeration of collective living quarters, as well as the operative verification
of the inhabited condition of the buildings, which were not verified in the 2017
test.
For this operation, with the intention of testing the public bidding process
to acquire the devices that will be used in the 2020 Census, a similar process
was carried out to purchase the required MD. Unlike the 2017 Test, only one
brand and model that complies with the minimum characteristics and
technical specifications required and defined from the results of 2017 was
purchased. One of the bases of this bidding considered a test of the devices,
in which the transfer of information was proved through the use of a USB OTG
memory, as well as the duration of at least eight hours of battery, for which
tools were used ad-hoc and processes were implemented to guarantee the
best device selection. The result was the purchase of 243 MD of the best offer
considering the aforementioned tests.
The use of Delphi Rio de Embarcadero Rad Studio was defined for the
development of the computer tools, which provides a technological platform
more oriented to the development of mobile applications, in particular for
devices with Android operating system, in such a way that systems were
optimized for the training of the personnel, the processes of information
exchange between the different operatives, the collection module of the
Census Administrator, the synchronization mechanisms for the transfer of
