Aerial Survey
One of the most common, versatile, and economical forms of remote sensing is aerial photography. Historically most aerial photography has been film based. In recent years, however, digital photography has become increasingly widely used. Aerial photography gives a bird’s eye view of large areas, enabling us to see earth surface features in their spatial location. CSW now will use the UAV aerial photos technique. In this technique CSW can get a resolution of 1cm with 100m flying height, and can build also the DTM directly with very accurate results.
GIS Mapping
Geographic information systems are computer based systems that can deal with virtually any type of information about features that can be referenced by geographical location. These systems are capable of handling both location data and attribute data about such features. Much of the power of a GIS comes from the database management system that is designed to store and manipulate these attribute data. CSW can apply all survey works not just in CAD format but in GIS format with complete data base for decision makers.
Remote Sensing
Is the science and art of obtaining information about an object, area, or phenomenon through the analysis of data acquired by a device that is not in contact with the object. The subject of remote sensing from space is rapidly changing one, with numerous countries. CSW uses the different satellite images (Spot, QB, WV2) with different resolution for many applications such as City planning, Classification of different objects, Environment, Digital mapping and for GIS applications.
Underground Utility Detection
Surveying of underground utilities such as buried pipes could be done using the RD8000 device and other Radar penetrating waves. Buried pipes and Surveying utilizes the principles of control, land, geophysics, and topographic surveying to control, locate and map underground and surface pipes.
Hydrographic Survey
Is the science of measurement and description of features which affect maritime navigation, marine construction, dredging, offshore oil exploration/drilling and related activities Strong emphasis is placed on soundings, shorelines, tides, currents, sea floor and submerged obstructions that relate to the previously mentioned activities. The term hydrograph is sometimes used synonymously to describe cartography of water bed, which in the final stages of the hydrographic process uses the raw data collected through hydrographic survey into information usable by the end user. Hydrographic survey is collected under rules which vary depending on the acceptance authority. Traditionally conducted by ships with a sounding line or echo sounding, surveys are increasingly conducted with the aid of aircraft and sophisticated electronic sensor systems in shallow water.
Geodetic Surveying
That type of surveying which takes into account the true shape of the earth is defined as geodetic surveying. The data of the various geodetic surveys are of great importance because they furnish precise points of reference (GCP), to which the multitude of surveys of lower precision may be need.
Strata Survey
Job title or function
How to define the boundary of Strata Unit? Distance of outer to outer that are not common wall to another unit or otherwise the median of wall is to be consider as boundary common to each other. Unless otherwise is specifically required the boundaries of strata unit should follow features such as the inner surfaces, median plane, or outer surface walls, floors and ceilings.
