Technology as a major force behind most of the developments experienced in many parts of the world has taken various dimensions in that each and every sector are affected in one way or the other. It ranges from engineering, mathematics aspects of technologies, science which is a major force behind the technology aspects and also the engineering aspects of it. Geospatial Information System can be categorized as an engineering which applies technology majorly in its operation. It is a fast growing industry as can be put by some scholars though it faces a major challenge as being one of the fast growing industry with very few skilled workers.
The technology involving is very important in making critical decisions in the field of technology. Experienced GIS specialists may decide to specialize in various sectors. Some may focus on the programming aspects and others may major in the development of the GIS software which in turn can be used in other ways to improve the users live. These types of the software can be used in the field of the mapping. It is referred to as the remote sensing or a type of a mapping in which technology takes a bigger part of it for the achievement of the objectives.
The software can still be used in the creating or editing the spatial data, inputting data into a GIS system, it can also be used in changing maps, aerial photographs and some other important data into a digitized system that can be further is stored for future use by the specialists. It has become essential to use the databases and the Geographic Information System and then turn the data into usable information. Basically, the traditional geologic map expressed the understanding of the field. At some points, some information may not be all that be useful but they can be transformed into some other useful data and be stored further and be used in regional data analyses.
With reference to the development of the geologic databases and GIS, it is necessary for one to be mindful of the quickly changing and the analyses of the geological data and their possible presentation. Most of the aspects can be incorporated within one single GIS set, these are like geologic, paleontologic, climatic, hydrologic, ecologic, topographic and many others all can be integrated into a single set of the GIS software than can be used in the operation of the remote sensing, which is basically for the mapping purposes.
The software provides the geoarcheologists with very important and vital tools that they can use in processing a vast amount of information which in turn promote some new possibility in the pattern recognition, landscape analysis and most importantly helps in the data visualization which was not feasible before the introduction of the technique, it is believed that with the incorporation of more appropriate scales within the field which is now available through the satellite remote sensing, it is through this that the prospects of the technique seems tremendous.
The software is said to be capable of manipulating data in either vector or in a raster format. From the definition, rasters are believed to be grid cells of some specified dimension and specific software is used in manipulating data in this case which is known as the GRASS for manipulating spatial data in this case. On the other hand, vector based software is mainly for linear data, for instance the ARC/INFO. The most suitable example is the drainage networks.
Most of the archeologists are focused on the spatial arrangement of the physical features and their relation with the other important parameters like time, climate, soils and also the land used. The software has the tasks of manipulating the information provided to come up with a comprehensive data analyzed and one that can be used to come up with appropriate results. It is understood that most of the remote sensing data can be directly be fed into the GIS since it has an integrated image processing capability. Another vital feature is that the software has the ability to recognize the various patterns once some data has been feed into it. The most important application of the remotely sensed data is basically for the classification which is in some aspects the process of organizing data into distinct categories in terms of land use or vegetation types in that regard.
Some regions could be inaccessible in that the information obtained could not be sufficient for the analysts due to few maps in such regions, it would be wise to use the combined effort of the GPS and GIS which in turn may provide a powerful combined methodology for the researchers. For example, National Aeronautics and Space Administration’s (NASA) LANDSAT imagery and some GPS data were used to come up with the GIS of the Middle Holocene which was in turn used to study the roots of the agriculture in southern Arabia. They were capable of documenting the data they obtained and they analyzed and made some vital classifications and generated some maps in the process.
It is believed that there is a major challenge to the researchers in terms of the scale they use coming up with their observations. It is believed that geologists and the archeologists operate in totally different scales from each other. Whereas the archeologists work within the human timescales of years, decades or even centuries, geologists may even work with more than million years of artifacts to get information of a given area. The scale of a given map normally can give the control of the features it can adequately represent in the normal way. It is believed that the details of the mapping normally changes with the kind of the scale that was used in gathering the artifacts. From the basic understand of the approximation with the use of the scale, the smaller the scale, the larger the interpretive as opposed to the actual representation on the map.
Conclusion
The technique is a powerful tool in the analysis of the groundwater exploration since it is believed to be less expensive and very quick to launch as compared to other techniques. It helps in getting vital information concerning the prospects, depth and quality of the landscape in a given map. It is a very useful tool in the preparation of the groundwater prospective areas mapping and management plan of the dairy farm in a scientific basis. The information obtained may be used in coming up with a feasible development plan for a given organization.
