National Agricultural Survey 2017

The tasks carried out in the information processing are described below.

1. DATA CAPTURE
   The data capture in the National Agricultural Survey 2017 was through the digital form captured in a tablet application which was validated by a team of consistency analysts to ensure that they do not present difficulties during the field operation.
   With this process, the survey official first filled out the digital form, then at the end of the interview he was instructed to export the database of the agricultural unit and send it to the central headquarters servers after reviewing the information completed, to which was directed to look for an internet booth, from where using the address, username and password, he proceeded to send said information through an integrated information system via the web.
   For the daily income it was not necessary that the questionnaire be complete, so the application allowed him to modify the information as many times as necessary, but only until the information is completed, at which time he should save the information by placing the agricultural unit in "Closed" status so that the system can proceed with its consistency.
   If once closed, it was necessary to modify the information, this process was only possible, through the computer team, who coordinated the cases with the consistency area and, according to their need, proceeded to correct them.

2. BASIC CONSISTENCY
   Coverage: The coverage process is carried out by the INEI Consistency staff, consisting of the crossing of information between the framework and what was actually found in the field. In the case of the National Agricultural Survey, we worked in two stages according to the natural region; First stage: Sierra; Second stage: Costa-Selva. The progress of coverage at the national level was monitored from the Lima headquarters through a series of reports, which guaranteed that the agricultural units are covered and consistent according to their natural region.

Structure: The structure process is carried out by INEI's OTIN staff. This process consisted of ensuring the integrity of the chapters that correspond to each agricultural unit according to their agricultural activity carried out by that agricultural producer in the reference period.

Basic consistency: Basic consistency is performed by the ENA and OTIN consistency staff together. The consistency analyst defines a set of flow rules, default values, etc. that apply to the database. The OTIN programmer implements and incorporates these rules into the basic consistency application. The process operators execute the basic consistency application and the consistency analyst verifies the obtained result.

3. CODING
   The coding process is automatic in the tablet application, however there are cases in which the interviewer was unable to determine the name and / or type of the crop, sub product and / or derivative, in these cases the coding is carried out by INEI's coding analysts and OTIN process operators using an interface to assign their corresponding codes in the database.

4. CONSISTENCY
   Consistency is performed by ENA and OTIN Consistency staff together. The consistency analyst defines a set of consistency rules that apply to the database. The OTIN developer implements and incorporates these rules into the consistency application. The process operators execute the consistency application and the consistency analyst verifies the obtained result. To facilitate the work of process operators, the process application for data processing was implemented, which consolidates in a single application all the processes involved in this task. Consistency was also a parallel action with the collection of information because, when entered into the survey database in a timely manner, it was immediately reviewed, consistent, verified and if errors or omissions were detected, they were gradually delivered to the operational headquarters for their timely recovery, correction and / or verification in the field and, if necessary, the information was returned to the headquarters.

5. RESULTS
   Generation of results: 23 data tables were generated according to each chapter of the form, each identified with a unique identifier (ID) in each table.

6. PRODUCTS
   From the database of the definitive results of the National Agricultural Survey, the microdata is generated as a product in the SPSS Database, which includes all the chapters and sections of the virtual form.
