For the data acquisition at small areas or for individual objects digital camera with calibrated metric lens or calibrated video cameras are used. For more precise works at small surfaces terrestrial laser scanner or modern geodetic instruments are used. For the cadastral or topographic surveys GNSS instrument is used..
What is data acquisition in data mining?
Data acquisition has been understood as the process of gathering, filtering, and cleaning data before the data is put in a data warehouse or any other storage solution. The acquisition of big data is most commonly governed by four of the Vs: volume, velocity, variety, and value..
What is data acquisition science?
Data acquisition is the process of taking measurements of real-world physical occurrences using signals and digitizing them so that a computer and software may alter them..
There are two main ways that the geologists collected data, through their own fieldwork and through reviewing information already available. Fieldwork involves collecting original data for the purpose of the research aims.
May 2, 2007“Geological data acquisition” is a general term for the collection of observations and measurements by direct observation of exposed bedrock
There are four methods of acquiring data: collecting new data; converting/transforming legacy data; sharing/exchanging data; and purchasing data.Common Data Acquisition Authoritative Data SourceNewly Collected Data
Are 3D visualization systems useful for field geology?
Finally, 3D visualization systems represent the ultimate future for field geology, but at the time of this writing there is no practical system that is useful for the field environment.

What are the four methods of acquiring data?
Bureau of Land Management (BLM). There are four methods of acquiring data:
collecting new data; converting/transforming legacy data; sharing/exchanging data; and purchasing data
This includes ,automated collection (e.g., of sensor-derived data), the manual recording of empirical observations, and obtaining existing data from other sources.

What is the Earth MRI acquisitions map?
The Earth MRI acquisitions map provides you with contact and related information for Earth MRI funded data acquisition projects.

Who collects data from the USGS?
In the USGS, most data are collected by employees and/or their contractors. While USGS can obtain some data from outside sources, we recognize that the bulk of an employee's work is the creation and maintenance of data.

Method of viewing geological details from aerial images
Aerial photograph interpretation is a method of extrapolating geological details of the ground surface from aerial images. It allows geologists to analyze the distinguishing geological features and structures, plant cover, past history of the site, soil properties, and topography of the study area. It is crucial in the early stage of a geological mapping as it is less time-consuming and offers important data at a minimal price. It is also commonly used in other industries such as forest management, environmental science, disciplines of engineering, and investigating aviation accidents.
Provenance in geology, is the reconstruction of the origin of sediments. The Earth is a dynamic planet, and all rocks are subject to transition between the three main rock types: sedimentary, metamorphic, and igneous rocks. Rocks exposed to the surface are sooner or later broken down into sediments. Sediments are expected to be able to provide evidence of the erosional history of their parent source rocks. The purpose of provenance study is to restore the tectonic, paleo-geographic and paleo-climatic history.
