Rural cadastre in Ecuador – MAGAP

Project Description

In early 2013, the Ministry of Agriculture, Livestock, Aquaculture and Fisheries (MAGAP) of the Republic of Ecuador, within the SIGTIERRAS program, hired NIP, S.A. to develop the survey and update of the rural cadastre in two large territorial areas.

  • Zone 1 included the cantons of Antonio Ante, Cotacachi, Pedro Vicente Maldonado, La Concordia, Flavio Alfaro and Santa Lucía. The total number of properties raised was more than 163,253. .

  • Zone 3 included the cantons of Riobamba, Pangua, Tosagua and Portoviejo. The total number of properties surveyed amounted to more than 187,995.

During the years 2013 – 2015 NIP, S.A. deployed field and cabinet teams (more than 800 people) to carry out the work that was successfully completed by the end of 2015.

Tasks developed


Training courses were held in all the cantons operated so that the work was done by local staff. The subjects taught have been mainly:

  • Juridical, possession of land.

  • Cartographic interpretation, photointerpretation, GPS management and tape measure.

  • SIG and digital mapping.

  • Use of digital databases.

In total, more than 600 people have been trained, mostly (90%) with a baccalaureate degree and 10% of engineers and lawyers.

Communication / Socialization

Before the beguining of the work and the completion of each canton, communication tasks
have been carried out with the local authorities (GAD) and with the main agrarian groups and communities involved.

In the course of the survey, two basic types of communication have been carried out:

  • General, using radio wedges and press advertisements.

  • Individual, by periphery and door to door to locate the largest possible number of owners.


This part is the most complicated of the projects and consists of the realization of a field visit together with the possessor, owner or valid informant to collect the data on the possession, such as:

  • Identification of the property

  • Identification of the possessor / owner / possessor.

  • Legal status of the property.

  • Land use.

  • Natural coverage.

  • Buildings.

  • Improvements and installations.

  • Access to services.

  • Sketch of the property.

  • Sketching of buildings.

  • Photographs of buildings and legal documents.

More than 320,000 land survey cards have been made in the field, in each of which more than 100 entries appear, all in digital format under free software applications designed by NIPSA on tablet and Android OS.

Digitization and Quality Control

Processes for creation of the continuous and definitive database in the format of the client:

  • Concordance between sketches and landmarks.

  • Automatic quality control: more than 200 validations are processed in each building.

  • Semi-automatic quality control, more than 25 topological validations are processed for each site.

  • Manual quality control: all possible errors that have not been detected by previous processes are verified.

  • Once the quality controls are passed, the premises are integrated into the customer database, checking the overlaps and checking the continuity and homogeneity of the public boundaries.

Public Exposure of Results (EPR)

During which it is proceeded to inform all the owners that they wish of the obtained results and at the same time to gather new information to update the existing one.

  • More than 230 public expositions have been held, with an average duration of 3 days each.

  • Legal guidance has been given in order to legalize the properties to all the possessors who have requested it.

Final delivery

With all the data collected and contrasted in all the mentioned processes, it comes the creation of a unique database by canton, which is delivered to Sigtierras for its implantation.
