Project Description

NIP, SA, in consortium with the Navarra company TRACASA (50%), was awarded two contracts for the development of thematic cartography (Lot 1 and Lot 2) at the end of 2013. The works affected a total of 105 cantons and an area of approximately 121,610 km², developing thematic maps of the territory at scale 1: 25,000 with details of 1: 5,000.


Tasks developed

Geomorphology

Geomorphological study in 105 cantons with an area of approximately 121,000 km², 9,000 geomorphological units interpreted and 221 types of differentiated geoforms.

Geopedology

In 105 cantons with an approximate surface area of 121,000 km², more than 8,000 surveys were carried out, 4,400 surveys and 17,000 samples analyzed in the laboratory. The following studies have been carried out:

  • Land use capacity, 8 differentiated classes of land use capacity and 65 management units.

  • Difficulty of tillage, 5 different classes of tillage difficulty and 63 tillage units.

  • Threat of water erosion, 5 different classes of risk of water erosion.

  • Infiltration speed, more than 6,000 tests with two techniques to contrast results.

Coverage and Productive Systems

In 105 cantons with an area of approximately 121,000 km².

  • More than 100,000 doubts analyzed.

  • 8,839 chips and 35,356 crop photos.

  • 9,847 files and 9,847 photos of natural hedges.

  • 161,397 simple tokens.

  • 110 surveys of key informants.

  • 5,160 surveys (sheet) to producers.

Volcanic hazards

Map of national risks of the most active volcanoes.

Accessibility

Four national maps, 283,000 km², with the following studies:

  • Road network

  • Collection centers and agricultural facilities.

  • Important economic centers.

  • Homogeneous areas.

For the accomplishment of these works the following specialized personnel have been counted on:

  • 20 soil scientists.

  • 20 geologists.

  • 17 agronomist / environmental / geographer photointerpreters.

  • 21 field technicians (agronomists / foresters).

  • 68 Field Assistants.

  • 2 SIG technicians.

  • 6 specialists in quality control.

  • 5 technicians for the elaboration of memories.

GeoPortal developed by NIP, S.A. shows, easily, all the geographic information obtained as well as all the data (graphs and alphanumeric) that have served as basis for the elaboration of the thematic maps. This information can be consulted at: http://geoportal.sigtierras.gob.ec:8080/GeoserverViewer/
