GIS/GPS based Survey

The efficacy of GIS as an adept tool for decision-making and strategic planning is contingent upon the precision and authenticity of the database, encompassing both spatial and non-spatial components. These databases can manifest in diverse forms, spanning traditional paper-based maps, softcopy representations like PDFs and JPEGs, intricate AutoCAD renderings, field-generated reports, and organized tabular charts. However, the cardinal tenet in curating an impeccable and authentically reflective database is the role of comprehensive surveys. Surveys hold sway in two pivotal ways: they lay the foundation for crafting new maps for previously uncharted territories, or they elevate existing maps through geocoding and real-world alignment. Furthermore, surveys entail the meticulous collection of Ground Control Points, which stand as essential components for the accurate orthorectification of satellite imagery.

The meticulousness of a well-executed survey augments its status as a dependable cornerstone, capable of fostering well-grounded decisions in the realm of developmental planning for a designated area. DOS Infonet Pvt. Ltd. boasts a team of seasoned surveyors who are well-versed in a gamut of survey endeavors.
