How do you become a GIS Specialist? or How do I become a GIS expert?
Becoming a GIS specialist is a long-term process. It requires a lot of patience and self-learning. To understand any subject you first need to be familiar with the fundamentals of the subject. You can learn GIS fundamentals from different sources for free. For self-learners, we also made a roadmap for GIS to help them follow the right path.
Is GIS a good career?
GIS is a good career path for data scientists, civil engineers, environmentalists, urban planners, meteorologists etc. It is useful for all those studies who are in one way or another involved with spatial information. GIS helps scientists in better decision-making. It also helps them understand the spatial aspect of their data. GIS with expertise in another field provides flexibility and maximized productivity. For example, if you are an environmentalist and have knowledge of GIS. This will give you an edge over the other fellows in managing and collecting geospatial information.
How long is the GIS course?
Just like any other study, GIS also takes time for understanding the basic concepts. There are many online sources for learning GIS. You may also check your local institutions or relevant public departments for proper GIS training. Usually, the introductory courses stay between 1 to 4 weeks.
Is GIS Difficult to learn?
Nowadays, almost everyone who uses the internet is using GIS in his daily life in one way or another. Daily uses of GIS are Google Maps, Flight radar, Weather forecast maps, etc. GIS basics are quite easy to learn but just as with any other subject, everything takes time. GIS may also involve programming and coding knowledge for mastering, which may make it somewhat difficult for some GIS learners. Coding in GIS is not mandatory but an additional and desired skill.
How do I become a GIS Developer?
GIS development requires some mandatory skills i.e., Python, R, JS, SQL, etc. But before that, it is important to work on the basics of GIS which doesn’t require any coding knowledge. For the ease of future GIS Developers, we made a detailed Roadmap for becoming a GIS expert.
Is coding needed for GIS?
Coding in GIS is a powerful skill but it is not a mandatory skill to have for a GIS expert. It is recommended to have some basic coding knowledge for automation purposes. In ArcMap, you can still automate your geoprocessing without coding by using the Model builder tool.
What is WebGIS Developer?
WebGIS developer is a person who has a background in web development and also in GIS. Web developers who want to become webGIS developers would require to learn some JS libraries such as Leaflet.js, Mapbox, Google Maps Platform APIs etc. The GIS person wanting to become a WebGIS developer must learn some basics of HTML, CSS, and Javascript.
