Taking into account the profile of the target client, the variables of interest are identified and an analysis of geographical concentrations is carried out, which offer guidance on the most representative characteristics of the population, in this way, the results are supported under a global perspective and only as a trend on areas with potential for commercial performance. By the foregoing, within this document analysis will be carried out that will be able to propose an optimal sector for the location of a new specialized coloproctology center in the geographical area made up of the municipalities of Duitama, Sogamoso, Paipa, and Tunja, is that how The following methodology would be applied based on two components, component A (geomarketing analysis with secondary information) and component B (geomarketing analysis with field validation). The geomarketing analysis with secondary information is based on the use of digital maps with sociodemographic information of the analyzed city and information from free databases, processing from statistical and quantitative methods supported by geographic information system tools. On the other hand, the geomarketing analysis with field validation is the most reliable part of the study where the hypotheses obtained in the first component are confirmed and thus have greater certainty of the decisions to be made. This process is executed with the help of surveys, where it begins with a pre-operational phase, corresponding to the planning stage that consists of defining the size of the sample and the content of the form, after which the execution is given, supported by the TaskGo application, which allows georeferenced data to be obtained in real-time, and thus later to be able to carry out the validation with the GIS tools and the statistical processes, complying with the required standards. This writing shows the theoretical, technical, and practical inputs that were developed throughout the internship, as well as its execution results and conclusions. Recognizing the importance of the integration between the theoretical heritage and the practical component as two necessary elements on the way to the professionalization of the topographical engineer.Ítem Apoyo técnico e investigativo para la cuantificación de biomasa y stock de carbono, utilizando datos LiDAR de alta densidad, para parcelas en el departamento del Chocó, caso de estudio: Medio Baudó y Bajo BaudóIván Darío, Silva Luis; Erika, Martínez Bonilla; Figueroa Fernández, Alberto; Barragán Zaque, William Benigno; 0000-0002-8234-1874The present work aims to adapt a methodology for the quantification of biomass and carbon stock in high resolution, for 3 plots located between the municipalities of Bajo Baudó and Medio Baudó in the department of Chocó, generating the Digital Terrain Model (DTM) and the Digital Surface Model (DSM) through LiDAR data modeling. Optical remote sensing technique, which uses laser pulses to calculate the limit distance between the sensor and the target, and according to this obtain heights and values in X and Y, in addition to using secondary information to generate elevation models. The volume of biomass for each of the plots under study was obtained through the development of vegetation height models, based on the generation of digital terrain models (DTM) and digital surface models (DSM), which were generated based on classified LiDAR point clouds. A validation of the models was carried out and the carbon and CO2 equivalent for the AOIs was calculated from the Corine Land Cover map at a scale of 100,000 for Colombia. The biomass and CO2 data obtained are approximate values, since the model was not calibrated with dasometric data from the study area. The scope of the project provides a first phase of characterization of the area of interest, to know the biomass and carbon stock data that the study areas harbor and to propose the collection of field data to adjust the model.Ítem Caracterización topográfica de la Laguna Sagrada de Siecha (PNN Chingaza), utilizando nubes de puntos de alta densidadSuárez Saboyá, Ana María; Barragán Zaque, William BenignoThe present work consisted of demonstrating the efficiency of point clouds for the realization of the topographic characterization of a high mountain area in the Lagunas Sagradas de Siecha (PNN Chingaza), area chosen for the level of difficulty and because it allowed encompass a body of water and a mountainous formation.

To perform this work, the use of remotely operated aircraft was implemented, which allows the development of a topographic survey obtaining products with both high precision and resolution. In order to achieve this and to develop the topographic survey, two phases had to be performed: one in the field, which consisted in performing the flight and lifting the control points: and the other one indoors, where all the information was processed. This fieldwork was carried out in an area located in Cundinamarca, close to northern Bogota, more precisely on the road to Tunja in the province of Sabana Centro. The survey covered an approximate area of 1.5 square kilometers that presented a variable level in altimetry. Once the data were obtained in the field and processed with the software designed for the aircraft, the error rate that the information could have had it was identified by performing different processing tests, which allowed to determine that the greater number of control points, the more improvement in the reduction of the obtained error is shown. Upon obtaining this result and determining the optimal situation to achieve the minimum error, a repetition of the process was done in two different software. The variations that could generate any error in the final products were determined and then compared with the mapping of the zone raised by the IGAC with conventional methods.Ítem Implementación de prototipo de aplicación web para el diagnóstico del inventario de fallas en el espacio públicoRojas Barbosa, Carlos Eduardo; Barragán Zaque, William BenignoThe Urban Development Institute is one of the entities that are responsible for maintaining the public space in Bogota, which is a very important entity that the city has approximately 36 million m2 of public space, of which less than half They are in good condition. In relation to this, it is proposed to implement an application prototype that allows optimizing the diagnosis in the fault inventory. The pilot of the prototype was made on a section of the NQS avenue, at an approximate length of 1.85 km, where the tool was tested on two platforms to compare, compare with the traditional method. To develop the prototype, use the management of the database, geographic information systems, cartography and other knowledge of engineering, looking for a functional tool with good performance.Ítem Mantenimiento y actualización de la GDB de aerofotografías análogas y digitales con su respectiva georreferenciación y control de calidadMerchán Cantor, Andrea del Pilar; Barragán Zaque, William BenignoThe quality control of photogrammetric flights is a procedure that is part of the cartographic process, its purpose is the evaluation of each aerial photography including its vector information to establish if it is suitable for the generation of basic cartography. Once this process is done it is possible to obtain a single GDB that contains all the information of similar flights in a reliable way. The present project showa the process for the realization of this work through the ArcMap software and the IGAC Geocarto consultation and management portal.Ítem Mantenimiento y actualización de la GDB de aerofotografías análogas y digitales tomadas a lo largo de la historia por el IGAC con su respectiva georreferenciación y control de calidadPardo Rodríguez, Brayan David; Barragán Zaque, William BenignoThe internship was born from the need to execute the standardization for the analogue photographs database that the institute have for its own and from the need for verify the georeferencing of those. All this for improve and make easier the posthumous processes. The development of this internship took four months and a total of 384 hours, in that time, an analysis for 74 flights, 15661 photographys and its repective geodatabase was made, using tools from software as ArcMap and Inpho, this last one with its Match At application. Also, the execution for this internship allowed to reach the purposed goals and getting as a result the correct geodabase estandarization, the georeferencing verification and the generation of a relational model that pretends to help into the consolidation of the global geodatabase for the area.Ítem Mantenimiento y actualización de la GDB de aerofotografías análogas y digitales tomadas a lo largo de la historia por el IGAC con su respectiva georreferenciación y control de calidadFonseca Roa, Joan Sebastian; Hernández Guzmán, María Camila; Barragán Zaque, William Benigno; Galvis Lagos, Wilffy CeciliaThe Instituto Geográfico Agustín Codazzi – cartographic agency of Colombia - has made throughout history the capture of analog and digital aerial photographs of the national territory, which have been compiled in Geodatabases (GDB). This Degree Work exposes the procedures for the Maintenance and Updating of these databases, which include raster information and a set of vector data which, after checking their georeferencing and quality control must been shown coherent with each other; otherwise, existing anomalies are identified and reported.Ítem Metodología para el diseño de un vuelo fotogramétrico usando UAV´SRiaño Rodríguez, Edgar Roberto; Barragán Zaque, William BenignoThe purpose of the design of a photogrammetric flight is to be able to represent on a map with an appropriate scale the flight lines to be followed, the capture points of the images and the flight height. This work proposes the adaptation of the design of a photogrammetric flight that is normally done from a manned aircraft to be able to do it with an RPA1, this in order to be able to implement this data capture technique for the support of small, medium and large projects. engineering in a more efficient and economic way. The correct design of the flight improves the accuracy of the abstracted information of the terrains, which will finally be reflected in the final deliverables of the flights such as ortomosaics, MDT2, contour lines, dense point clouds among others. For the development of this work it was necessary to inquire about photogrammetry, digital cameras, and basic programming, all this in order to create an interface layers to provide the user with the basic parameters necessary to carry out a photogrammetric flight. The equations that were used are adaptations of the photogrammetric flight design manual created by the CIAF3 in 1981 and to be able to calculate the necessary parameters, it was decided to use the Matlab program and its GUI4 application which allows to create interfaces capases to solve programmed algorithms in a fast way and in a very friendly way for the users. The photogrammetric flights must have a logical sequence, and the calculation of their parameters are based on the type of terrain where they are going to be carried out. If there is a flat terrain, the problems are not greater because the flight heights above ground do not vary from way that may affect the quality of the information, but on the other hand fly over mountainous terrain implies establishing tolerance ranges where flight heights meet the overlap and scale determined by the user. This methodology proposes a solution to these two scenarios through a user interface from the Matlab environment and the support of the Google Earth and Mission Planner programs.
