Background

Improving the efficiency of canal systems is more complicated than that of groundwater, which will in the future remain the dominant water transport technique in developing countries. The standards used for the design of irrigation canals in many countries have not kept up with the development of new technologies. Global Position Systems (GPS) and Geographical Information System; integrated systems have emerged as powerful tools in the conduct of large scale surveys in recent years for mapping and to create spatial database of any Geographical area in any scale and integration of non-spatial information, modeling, analysis and generating statistical data according to the nature of application.

Project Description

This study involves four phases which include preliminary study and planning, data collection, data processing, results, and analysis. The methodology plays an important role in implementing this study accordingly. The first phase is on the preliminary study and the planning of the work which are crucial parts of the study that require a lot of reading and planning. The first phase also includes calibration of the equipment and measurement of data. The next phase is on data collection using drone images and getting the detailed plans. Then, both sets of data are processed for the third phase of this study which is data processing. The UAV images are processed using the software which can generate the X, Y, and Z coordinates of the proposed road. This phase also comprises the construction of road mapping of the area of interest. After the data processing is completed, the results are analyzed

The main objective was to get accurate terrain information for the construction of Canals. Spatial analysis techniques were used to extract the features of the land components of the individual owners which are acquired by the government for constructing the canal. It included the registered farm areas of the individual owners, road, water bodies, transmission tower, forest area, village Abadi, etc. For getting information about the elevation of land, Digital terrain model was generated. It helped us in determining elevation points that diverted the flow of water. An Orthophoto was built for visualizing the entire area to spot the land features.

Data Acqusistion

This canal survey has completed with186 sq.km pre-planned grid mission path. The drone flight time depends on the area's mission and height. between the two aerial imagery is 70% which is a help acquire an ortho-mosaic flight height of ap 100meter above from the images with a ground sampling distance is less than collected. accurate and detailed information about the canal. In addition to improving the quality of the project added GCPs which is measured coordinates by the DGPS instruments. This canal has a 22 GCPs coordinates along with the canal bed. The accuracy of the XYZ coordinates up to 15cm. This canal project took 2 days to collect the raw data image.

AIRPIX provided drone-based project monitoring and site analysis solution to Western Corridor’s 421km stretch from JNPT to Vadodara with quarterly reporting and status based on chainage, ROB, RUB and other critical locations, thus giving critical insights to higher authorities, Government officials and stakeholders

Image Processing

The drone survey carried out high-precision geotagging images. The images were imported into photogrammetry software. Using this software, where all the images were processed to generate the map outputs 2D and 3D. An ortho-mosaic map provides information about the canal and you can plan your development with the help of the map. The flight was conducted at a constant height and Maintaining constant parameters of the flight shall be led to the good result. This whole process was complete in 1day.
