How is geographic data collected?
Surveying: It is the most holistic approach to data collection. Data are gathered either from on-site surveys or from remote sensing, photogrammetry, and GPS techniques and through their combination, we have primary data collection which results in scientific maps and researchers..
How is GIS data acquired?
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 are the methods of data acquisition in geography?
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..

Geoprocessing is a framework and set of tools for processing geographic and related data. The comprehensive suite of geoprocessing tools can be used to perform spatial analysis or manage GIS data in an automated way.
5.2 Geographic Data Acquisition. Acquiring geographic data is crucial in any geographic information system (GIS) effort. It has been estimated that data
Acquiring geographic data is an important factor in any geographic information system (GIS) effort. It has been estimated that data acquisition typically
is an indirect methodology that utilizes the vast amount of existing geospatial data available in both digital and hard-copy formats.
Can GIS data be gleaned from a nondigital source?
Although these data sources are all cases where the information has been converted to digital format and properly projected for use in a GIS, there is also a great deal of spatial information that can be gleaned from existing, nondigital sources.

Data Types
The type of data that we employ to help us understand a given entity is determined by (1) what we are examining, (2) what we want to know about that entity, and (3) our ability to measure that entity at the desired scale. The most common data types available in a GIS are alphanumeric strings, numbers, Boolean values, dates, and binaries. An alphanu.

How are topographical and GIS data captured?
The vast majority of the today's topographical and GIS-data are captured from mobile and possibly autonomous platforms that operate from the air, on the ground (also indoors) or on the water and that are equipped with optical sensors.

Measurement Scale
In addition to defining data by type, a measurement scale acts to group data according to the level of complexity (Stevens, 1946). For GIS analyses, measurement scales can be grouped into two broad categories. Nominal and ordinal data represent categorical data; interval and ratio data represent numeric data. The most straightforward data measureme.

Primary Data Capture
Now that we understand the different data types and measurement scales available in a GIS, we must direct our thoughts to how this data can be acquired. Primary data capture is a direct data acquisition methodology usually associated with in-the-field effort. In the case of vector data, directly captured data commonly comes from a global positionin.
Web hosting service active from 1994 to 2009
GeoCities, later Yahoo! GeoCities, was a web hosting service that allowed users to create and publish websites for free and to browse user-created websites by their theme or interest, active from 1994 to 2009. GeoCities was started in November 1994 by David Bohnett and John Rezner, and was named Beverly Hills Internet briefly before being renamed GeoCities. On January 28, 1999, it was acquired by Yahoo!, at which time it was reportedly the third-most visited website on the World Wide Web.
