Ítem Organización de la información correspondiente a la red de nivelación nacional en el GIT de geodesia del IGACLópez Pinzón, Sergio Daniel; Quintana Puentes, RobinsonDuring the period between august 19th and November the 13th of 2017, was developed a practical and theoretical exercise, intended to organize information from the altimetry national network for the internal working group –GIT – of geodesy at the “Instituto Geográfico Agustín Codazzi IGAC-. As a result of this work, a digital format was obtained from the 10 lines altimetry extracts whose files were analog, as well as the transcription to digital of two books with information of elevation points coming from different lines of altimetry. All this information was gathered from data of the 1951- 1999 altimetry period. For a second instance, through the construction of a macro, we obtained the structuring of the altimetry extracts of 4 circuits of the network, these lines of altimetry were intended to make up each circuit to be calculated. Simultaneously, with the same activity, the Geographical Data Base –GDB- from tha National Altimetry Network, was structured along with another classmate. For this purpose a Python program was designed to energize the work, which was helpful to create and include t the GDB of 6 shapes of line type, and 6 shapes of point type, they represent the direction that follows an specific altimetry line and the geodesic points to make up a line or altimetry circuit .The last information corresponds to data of altimetry gathered from 2000 to these days.Ítem Recuperar, clasificar, y digitalizar la información de los proyectos de nivelación por el grupo interno de geodesiaFuentes Pineda, Andrés Felipe; Quintana Puentes, RóbinsonThe geodesy in the country is in a process of growth, where the Geographical Institute Agustin Codazzi is the main responsible for carrying out an adequate geodetic work in the country, for this it is necessary to organize in the information obtained, during the development of This project supported the process of leveling that is in charge of the Geodesy GIT of the institute. The leveling networks in the country are referred from a vertical datum located in Buenaventura, where from there the transfer of elevations is made to all parts of the country by means of geodetic leveling, therefore, during the course of the work of grade information was recovered from the 80s 90s of old leveling lines, important for adjusting the leveling circuits that are currently being measured in Colombia; In addition to this, a unique geodatabase was created for leveling in the institute with the objective of organizing all the information that was found in several dependencies, this in order to support and help the IHRS project where the entire national geodetic framework is needed. leveling information, gravimetry and calculation of geopotential numbers, this project facilitates the management of geographic information about the leveling networks of the first order in the country.
