In the past few decades, there have been significant changes in the job market, and for the better. Although new kinds of jobs have opened up in almost every sector, the maximum amount of boom has been ion the technological realm. With the rapid advent of technology and its influence on practically every sphere of the human existence has naturally opened up new vistas in the employment scenario. The GIS technology is no different, and there are a variety of different jobs that one can take up today if he or she is well conversant with the brand new technology. Naturally, there are a whole lot of students clamouring to study this technology in order to increase their chances in the related posts that are extremely lucrative; the rush has been picked up by the educational institutes pretty easily, and various colleges and universities now offer GIS courses. Given the high demand of these courses, the universities and colleges have opened up various kinds of courses in Geographic Information Systems.

While regular classes are available in colleges, online courses have also opened up for those unable to attend a regular university. Besides, certificate courses have also become much a rage among students wishing to pursue an optional course in GIS to keep their options open. Usually, the GIS student initially lands a job as an intern with a Geographic Information Systems firm or any field where this technology is used. Later on, the intern can rise up the ranks from intern through a GIS Technician or specialist and then move on to the managerial ranks. In between, the candidate can be considered for posts like a GIS Analyst or GIS Programmer. Of course, a candidate can apply anytime for any job in between those top and bottom ranks, and the selection is dependent on his or her qualification, aptitude and expertise. It is advisable, however, to ensure that some on-the-job training is acquired before applying for a full time job; this can be garnered only through an internship.

A student pursuing GIS courses has to study a variety of subjects, all of them highly technical. Therefore, opting for the course itself becomes a pretty practical experience in the GIS field, which is why it is termed as a vocational course. The syllabus of this course includes the following topics:
• A basic overview of the key concepts of GIS
• Basic spatial analysis
• Creating and editing datasets
• Application of 3D data
• Multiple coordinate systems
• Registration of raster and vector images
• Understanding and using spatial distribution
• Understanding the purpose and usage local spatial correlation
• Calculation of spatial densities
• Understanding the purpose and application of global spatial correlation
• VBA scripting
• In depth study of interpolation and geostatics
• Learning the meanings of various symbols and interpreting data
• Geodemographics

A lot of these courses can be divided into various sections. Make your choices carefully as you decide which ones you will pursue, and the choices must be made based on the career path you want to walk in. Initially, it is best to get a general overview of the field, which should be the very first course that you take up. Remember that a cartography course is mandatory.
