Administration of geographic information

Mainly based on cartographic information, alphanumeric and geographical database, and Reference base station (GNSS).

Cartographic information

The geographic database contains cartography with precise limits of the farms and lots harvested by 13 sugar mills. The thematic maps included in the system (map server) have been prepared from studies carried out by Cenicaña and other institutions such as the Agustín Codazzi Geographic Institute (IGAC), the Regional Autonomous Corporation of the Valle del Cauca (CVC) and the mills sugar bowl Commercial production data and mapping of lots and farms are supplied by the sugar mills. These

Map server

The map server integrates the database of the geographic information system (GIS) of the sugar sector with the databases of commercial production and the automated meteorological network (RMA) to deliver thematic maps by ingenuity, farm and sugarcane, with associated information that is necessary for the practice of specific agriculture by site in the Cauca river valley. It also offers an application for monitoring crop development based on satellite image analysis, and other applications for different purposes.

Alphanumeric and geographic database

A geographic information system not only feeds on geographic data but also alphanumeric data. The alphanumeric data correspond to all the data that Ingenios and Cenicaña collect and store in large databases. These data are those related to the crop and its management, for example: name of the farm, number or lucky code, variety planted, age, planting date, harvest date, tons of cane per hectare (TCH), yield Commercial, rain, among others.

Communication between the alphanumeric and geographic databases is carried out through a common field or column between the tables of both databases. The common field or "key" is made up of the code of the mill, the hacienda code and the luck or lot code. This field allows the GIS to be connected with the various databases within Cenicaña.

Reference Base Station (GNSS)

It is the reference base station for differential correction of data collected with global satellite navigation system (GNSS) devices.

The GNSS base station is located at a fixed point with precise geographical coordinates. It provides reliable information for different calculations and surveys of geodetic control, data collection for Geographic Information Systems (GIS) and photogrammetric surveys of terrestrial type, among other utilities. It records the data of the geographic coordinates during the 24 hours of the day and publishes them on the web every hour in intervals of one second (RINEX format).

Users of mobile GNSS can use the data from the fixed station to make the differential correction of the geographic coordinates recorded with portable equipment.
