Microsurvey starnet traversing settings software#
As the development of computer technology become so advanced the capability of software to handle images captured with certain overlapping coverage to produced 3D model has been proven capable of producing a high quality surface model as the raw data captured in 3D with instrument coordinates system. A 3D laser scanner captured image the same as photogrammetric camera that capture x and y coordinates and z value measured by distance from the instrument to the object. The then can be used to produce the real surface condition in relevant processing software which is suitable for direct measurement on the image or constructing DTM (Digital Terrain Model) the as what is possible in photogrammetry. more A 3D laser scanner is an active image capturing instrument that has the ability to accurately send a signal and capture it back in x, y and z dimension. Based on several studies on determining the suitable method to classify the groundwater zone, integrated assessment of thematic maps using a model developed based on GIS techniques is the most suitable method for groundwater potential zones prediction.Ī 3D laser scanner is an active image capturing instrument that has the ability to accurately sen. In order to predict the groundwater potential zones, different thematic maps have been prepared which includes annual rainfall distribution, land use, lithology, lineament density, topography elevation, slope steepness, drainage density and soil type. The various surfacial parameters prepared from remotely sensed data and ancillary data can be integrated and analyzed through GIS to predict the groundwater potential zone. They are particularly useful, very detailed and also show up features which cannot be seen easily on the ground. Remote sensing data from aircraft or satellite has become an increasing valuable tool for understanding subsurface water condition. Geological methods, involving interpretation of geologic data and field reconnaissance, represent an important early step in groundwater investigation. more ABSTRACT Groundwater is hardly and almost not possible to be seen directly from the earth's surface. Obviously, this adjustment result may be producing the output and the quality can be evaluated.ĪBSTRACT Groundwater is hardly and almost not possible to be seen directly from the earth'.

Then, the result of Chi-Square Test (Total Error Factor) from the adjustment must be in the middle within Upper and Lower Bounds for the data being process to passes the adjustment. In the StarNet system, the quality of 3D traverse will be evaluated based on the chi-square level achievement produced after the data has been processed in the systems. Hence, this 3D traversing is expected to generate the statistical summary test after a proper processing in the Microsurvey StarNet software systems. Therefore, 3D traverse network is performed using a high accuracy Topcon Total Station (ES 105) with 1 second angular and 2 mm distance accuracy to evaluate the impact of distance of each traverse line toward the quality of the closed 3D traverse.

According to this investigation, there are errors that need to be evaluated in this observation because of the data from the length lines observed, equipment used or the condition of the study area could produce some errors. Generally, this Deformation Surveys can be able to detect relative even absolute movements for monitoring of a pump base, storage tanks, retaining walls, slope areas and general ground subsidence. more 3D traverse network survey is one of the methods use by surveyor or engineer as a control network for deformation monitoring, as not all the area/position surrounding the building or high rise building suitable for GPS observation and that position unavoidablely required for monitoring of the building. 3D traverse network survey is one of the methods use by surveyor or engineer as a control network.
