GeoReferencing is the method of assigning the real-world coordinates to each pixel of the raster. Usually, these coordinates are obtained by doing proper field surveys and collecting coordinates with a GPS device for few easily identifiable features in the image or the map.
It is basically a means to associate something with locations in the physical space or the process of associating a physical map or raster image of a map with spatial locations.
The importance of Georeferencing lies in its ability to turn non-spatial imagery into spatial raster data for use in a variety of circumstances. Spatialized air photos can be used for GIS land cover analysis.
Following Are Some of the Uses of Georeferencing:-
• It makes the different imagery required for mapping. It explains how other data, such as the above GPS points, relate to the imagery.
• Necessary information may be contained in data or images produced at a different point in time. It can be used to compare this data with that currently available.
• Different maps may use different projection systems. The tools of Georeferencing contain methods to combine and overlay these maps with minimum distortion.
• Data obtained from surveying may be given a point of reference from topographic maps by the application of GeoReferencing.
• It may be required to establish the significant relationship between social survey results which have been coded with postal codes or street addresses.
Also, for other geographic areas such as census zones or areas such as public administration or service planning.
GIS Services is a technology specifically designed to capture, analyze, manage and present all types of spatial and geographical data.These services have aided national security and law enforcement as well. Several companies are reaping big benefits due to these GIS services. They rely on the data rooted in computer mapping and satellite imageries to leverage work efficiency, take strategic decisions and select a better consumer group and increase the efficiency of the business.
These services basically aids essential business functions such as marketing, logistics and strategic decision making. The company offering such services provides valuable support in defining business requirements.Also, industry policies and standards, database design and implementation, application development.
Services Providing Area
The GIS services uses technology to trace location.This is very useful in marketing and sales, logistics and transportation, human resource and other fields. It is well integrated with targeted marketing and market analysis, routing and logistics.
GIS is now a very important tool that helps the education department to send across the answers from local to global implications.
This technology helps biologists, ecologists, environmental regulators, astronomers, and miners etc to make difficult decisions regarding the handling of the earth’s natural resources.
Due to the improved decision making processes, as a result of GIS, service delivery and citizen management have become easier. As most of the data in the government is location-based.Thus, smoother operations can be expected.
GIS technology also provides good assistance in mapping and charting in Aeronautic and Maritime fields. It immediately starts producing geospatial data and provides high quality products with tools in making and maintaining the results.It also tracks the status and progress of jobs through the complete cycle.
The use of lidar data processing has erupted in recent years, for many good reasons. The Lidar technology helped in producing higher-quality results than traditional photogrammetric techniques that cost low. Therefore, this has created a huge accomplishment to a large extent by the automatically collecting measurements very densely. The progress in laser scanning hardware has been astonishing.
One of the major side effects of switching to lidar-based technology is that it has many challenges in increasing the data volume and the development of software processing abilities required. Fortunately, there are many benefits offered by Lidar technology such as LiDAR Mapping Services, lidar data processing workflow, and Lidar 3D Scans.
1. Have Lidar in LAS Format
Having a lidar in LAS format can be visible to the admitted but not to the one who is new to using lidar data. LAS stand for Laser is the industry standard format for lidar. This helps in choosing the best format that works best.
2. Make Sure the LAS Files Are “Tempered” for Use in GIS
When you have to use LAS, a lot of things go on between initial data collection of LAS files a ready to use the file. Therefore, you can use LAS as there are many flavors out of which some are better than others for use in GIS.
3. Consider Your Options
Look for a company that provides several complimentary options for accessing lidar. Basically, there are three primary data access tools: the LAS dataset, the region dataset, and the mosaic dataset. Therefore, if you will learn about them you will get a better idea to determine which one is for use.
4. Stage Data Appropriately
Lidar data is quite large and requires careful planning to avoid producing a network to its knees or making users wait for long to display.
Therefore, if you have to determine the best overall approach, make sure you get your questions and queries solved. Questions such as – How large is the dataset? And will the whole lidar samples process in order to ad-hoc queries?
Geographic Information Systems have a wide range of applications in different industries. These systems have become a key component in many organizations. With the chance of visualizing and analyzing data better industries are able to understand recent trends and relationships more efficiently. GIS can help answer many geography based questions and it is exciting to see how in the future these systems will improve.
There are a lot of GIS applications for different industry needs the most popular of them being-
- GIS In Mapping And Technology- If you have ever used Google maps to find a place near you then believe me you have made use of some kind of GIS technology. This is the central function of these systems and thus, they find used in any kind of mapping need and in the technology industry.
- Government Needs- From agriculture needs to surveying areas, flood damage estimation and even disaster management, GIS systems can be used in all such applications for government needs.
- Advertising- GIS today has even proved used for advertising as it can help in better decision making and identify areas where consumers are more likely to buy a certain products
- Medical- The health and medicine industry can benefit greatly with the use of GIS. It can help in the collection of health data of a particular area, map out areas where there is a disease outbreak and do so much more
- Insurance- Even here GIS systems prove useful in areas like catastrophe planning, risk prediction and analysis and customer service analysis

Seeing this it is clear that GIS are not just restricted to be used in a single industry but find application in so many organizations.
GIS has found use in many areas and has proven to be an asset to numerous industries. From agriculture to natural resource management and even urban planning GIS can be used in all such fields and many more to make better decisions and gain comprehensive geographic information about an area.
Though GIS applications may be many but when it comes to use of GIS in agriculture there is an essential role that these systems plays. Similarly even in natural geo resource management GIS can prove to be very useful. Some of the most important benefits of such systems in these field include-
GIS in Agriculture-
- With GIS systems people are able to map and project current and future fluctuations in precipitation, temperature, crop output and much more.
- These systems assist farmers in creating more efficient farming techniques which will yield better crops
- These systems also help in soil analysis to find out which places are suitable for a particular crop
- From area mapping to finding resources nearby there is a lot that these systems can do for agriculture needs
GIS in Natural Resource Management-
- From land covers maps to vegetation maps, soil maps and geology maps all these can be developed using these systems
- From gathering information regarding all present natural resources in a particular area to analysis and management all this can be done using this system
