DATA COLLECTION, SPATIAL DATA INVENTORY,  META DATA & MAP MAKING IN PURSUIT OF THE  TRUTH TRUTH, DATA, INFORMATION & KNOWLEDGE  ENHANCEMENT Is there such a thing as the “absolute truth? The term  data  refers to qualitative or quantitative attributes  of a variable  or set of variables. Data (plural of " datum ") are  typically the results of measurements and can be the basis  of graphs , images , or observations of a set of variables. Data  are often viewed as the lowest level of abstraction  from  which information and then knowledge are derived.  Raw  data , i.e. unprocessed data, refers to a collection of  numbers , characters , images or other outputs from devices  that collect information to convert physical quantities into  symbols. In English , the word  datum  is still used in the general sense  of "something given". In cartography , geography , nuclear   magnetic resonance  and technical drawing  it is often used to  refer to a single specific reference datum  from which  distances to all other data are measured.

For example, the height of Mt. Everest is generally considered as  "data", a book on Mt. Everest geological characteristics may be  considered as "information", and a report containing practical  information on the best way to reach Mt. Everest's peak may be  considered as "knowledge". Information as a concept bears a diversity of meanings,  from everyday usage to technical settings.  Generally  speaking, the concept of information is closely related to  notions of constraint, communication, control, data, form,  instruction, knowledge, meaning, mental stimulus, pattern,  perception, and representation. Beynon-Davies uses the concept of a sign  to distinguish  between data and information; data are symbols while  information occurs when symbols are used to refer to  something.  [14]   [15] It is people and computers who collect data and impose  patterns on it. These patterns are seen as information  which can be used to enhance knowledge. These  patterns can be interpreted as truth, and are authorized  as aesthetic and ethical criteria.  Raw data  refers to a collection of numbers , characters , images  or  other outputs from devices to convert physical quantities into

symbols, that are unprocessed. Such data is typically further  processed  by a human or input  into a computer , stored  and  processed there, or transmitted (output ) to another human or

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
