Isopleth maps simplify information about a region by showing areas with continuous distribution. Isopleth maps may use lines to show areas where elevation, temperature, rainfall, or some other quality is the same; values between lines can be interpolated.

The Prime Meridian divides the globe into two equal halves, the Eastern Hemisphere and the Northern Hemisphere. The longitude of a place is followed by E for east and W for west. 180° E and 180° W are on the same line. The vertical lines on a globe represent lines of latitudes.

1. Choropleth maps. A choropleth map is a thematic map where geographic regions are colored, shaded, or patterned in relation to a value. This type of map is particularly useful when visualizing a variable and how it changes across defined regions or geopolitical areas.

A Geographic Information System (GIS) is a computer system that analyzes and displays geographically referenced information. It uses data that is attached to a unique location.

GIS is a strong career, and it will be in demand for a long time. But like all careers, GIS is changing fast with new techniques every day. As a GIS specialist, your salary depends on your work experience and varies according to the job location and title.

A working GIS integrates five key components: hardware, software, data, people, and methods.

“Learning is neither super easy nor extremely difficult, its our interest and passion which makes it so”. GIS is a vast subject which starts with the basic concepts of Geography that is taught in Junior High School level to complex concepts involving algorithms, image processing, Spatial Models etc.

GIS is difficult because users focus on data , while GIS software focuses on operations. GIS is typically described as a set of operations applied to data: overlying polygons, creating buffers, calculating viewshed. Most commonly-used GIS software is also organized around operations.

If you dedicate time(enough time) to learn GIS, you will be good at it in a very short while e.g. Two weeks. Again it all depends with what you want to learn in GIS, if it’s use kf existing GIS software, even a week is enough. Going to analytic side of GIS you may take longer and so is programming.

GIS is a subject that can be self taught using online tools. As you have no doubt learned using search tools, a plethora of courses including several that are free. GIS in itself is not terribly difficult to learn.

Esri has many resources that will help you quickly learn about how GIS technology can help you work more effectively.

GIS certification helps you become an expert in your field and gives you confidence. Lastly, you get the necessary experience and knowledge to climb the GIS career ladder in your job. Overall, it depends on how much you think the GIS certification will benefit you and what you want to get out of it.

To become a GIS technician, you need a bachelor’s degree in geography, computer science, engineering, or a related field. Coursework in geography, computer technology, and cartography are all staples in programs that lead to work with GIS systems.

What jobs could one get related to GIS without having a GIS degree? Ordinarily, you’d need a GIS-related university degree. It’s the most straightforward pathway to placement. On the other hand, a degree may not be all that it takes to be hired for a GIS-related job.

Here are eight (out of many) careers you can pursue with GIS experience.

• GIS Developer. Developers in GIS create and modify GIS tools, applications, programs, and software.
• Conservationist.
• Law Enforcement.
• Cartographer.
• Health Geographer.
• Remote Sensing Analyst.
• Climate Scientist.
• City/Urban Planner.

The national average salary for a GIS Analyst is $60,597 in United States.

All things taken together, the future of GIS is very optimistic. It’s poised for even wider scale adoption than we’ve seen in recent decades, as more organizations learn how much business value can come from geospatial data.

The demand for GIS is growing. The U.S. government predicts Geographic Information System will be in high demand over the next decade, with annual salaries of $70,000. The Bureau of Labor Statistics predicts growth of 35% a year, with a shortage of trained people to fill the jobs.

Primary duties include using mapping software to analyze spatial data and design digital maps. GIS Analysts gather this information to make decisions about how land is utilized. They also anticipate and catalog geographic changes and maintain the digital databases that house geospatial information.

So I present to you the top 8 skills you need to be a successful GIS professional in today’s world.

• Basic Programming Knowledge.
• Involvement in Professional Organizations.
• A Great Network.
• Keep Learning.
• Software-Specific Knowledge.
• Analytical and Critical Thinking.
• Project Management.
• Sales Skills.

$60k is possible after a few years, even in your 20’s, but it requires a bit of luck, pushing yourself in your career, and living in an area of the country that’s good for GIS professionals. Finding a job won’t be easy. The job market is very competitive in urban areas, even for experienced professionals.

Spatial analysts need experience with mapping tools such as vector and raster data, and spatial modeling….5 Skills Every GIS Analyst Needs

• Possess strong IT skills.
• Can manipulate complex databases.
• Are highly detail-oriented.
• Are clean writers and thoughtful communicators.
• Can problem-solve individually and on a team.

GIS engineer is a great career option in today’s scenario. He can work as GIS analyst, GIS manager, cartographer, photogrammetrist, land surveyors, serving technician, mapping technician and drafter. Job growth in GIS engineer’s field has increased from 18 to 29% in past few years.

Six Things You Should be Doing to Enhance Your GIS Career

1. Continue a Habit of Lifelong Education. Take advantage of the range of training and learning opportunities available.
2. Consider Certification.
3. Interact with your peers.
4. Share.
5. Play in the Sandbox.
6. Pay it Forward.

A GIS developer is a software developer that helps in the designing, programming, and maintenance of GIS software. This is done based on what the organization or the clients asked for. As a GIS developer, you’ll make use of 3D and maps to organize your data using spatial analysis.

GIS is also valuable because it is not one tool but a system containing hundreds of tools in a single environment. GIS is also valuable because it helps communicate complex ideas because it uses the powerful medium of the map, which for centuries has helped to explain connections.

For the GIS Technician, GIS is the job. For a GIS user, GIS is an adjunct to or tool for the job. GIS Analyst – Probably more experienced than the GIS Technician and probably having some specialist knowledge of spatial analysis maybe in a particular field (e.g. oil sector, renewable energy, civil engineering etc).

Python is a scripting language incorporated into many GIS software applications such as ArcGIS and QGIS and is used to automate geoprocessing tasks. Python scripts are essentially a command-based script containing data types, statements, and functions that make up the geoprocessing instructions.
