Your #geospatial portfolio is proof that you know & understand #GIS concepts, so how do you build one?
If you are wondering what kinds of projects you can do to populate your geospatial portfolio and also gain knowledge as you do them.
Do not look too far, open this thread.

The fundamental thing about projects in GIS terrain is that all your project must have a study area. A study area is a place within the earth surface that you choose to perform your analysis on. E.g Landslide Susceptibility mapping in "South Eastern Nigeria...
South east is my study area here.
So, all your projects must have that and that's at your discretion.
Now let's dive in ✈️

Now let's dive in ✈️
1. Landuse Landcover Classification:
This will be done by all GIS analyst at one point or the other in their career, so it's good that you practice with it now. This project helps you to understand what the land is being used for - it's that basic.
This will be done by all GIS analyst at one point or the other in their career, so it's good that you practice with it now. This project helps you to understand what the land is being used for - it's that basic.
Generally, we have 5 major classes of landuse which are Bare lands, Built up Areas, Vegetation, Water bodies and Wetlands. To also make this more applicable, I'll advise that you also calculate the areas occupied by each classes.
This will give you more insights and help you make more informed decisions from your analysis.
2. Suitability Analysis:
This kind of analysis helps you to understand and know whether a place is is suitable for a defined use. Think of this analysis as what you perform to know if a particular kind of structure can be built in a particular place or not.

Although, It's not limited to that only. To be more niched you can check out site suitability and Land suitability Analysis.
3. Locational Analysis:
This is a technique for discovering, assessing & specifying the optimal placement of organisations,people or materials. You might be thinking of where to situate your business, where banks should situate their ATMs, this analysis comes in handy here.

4. Hotspot Analysis:
Think of hotspot as a particular location where concentrated number of things take place consistently. It could be an accident hotspot, a terrorist hotspot, fire hotspot and so on.
Think of hotspot as a particular location where concentrated number of things take place consistently. It could be an accident hotspot, a terrorist hotspot, fire hotspot and so on.
This kind of analysis helps you focus your energy on where the problem really is and then you can combat the issue that consistently causes accidents or sponsors terrorism in the examples above.
5. Network Analysis: This is directly related to those in the transportation Industry. This can help in managing transportation and logistical problems. Let's say the government is planning a new route for railways or even vehicles you could use this analysis to ....
generate the best route based on the different data you have at your disposal which would result in less traffic and even allow people to arrive at their destination much more faster.
Think of Google Maps.

6. Wetland Mapping and Monitoring:
GIS can help measure water turbidity check plant health and also check the level of moisture in the soil and so on period this can be rather technical as you would be looking to use some remote sensing equipment such as hyperspectral sensors..

like radiometer to get the spectral reflectance of crops to know their health and so on. All in all ecological students and researchers will find this very adventurous.
7. Landslide susceptibility mapping:
GIS can help you estimate places that are at risk of experiencing landslide. This is done by certain environmental factors that are available to the GIS analyst as data such as slope, geology of the Earth, digital elevation model (DEM), etc.

By analysing these factors, a map of the study area will be gotten which indicates the areas that are vulnerable and policies can be implemented based on the results of the map. Needless to say that analysis like this save millions of lives annually.
8. Flood Risk Assessment:
This is also obvious from the name and the method is quite similar to that of landslide mapping but the data sets are very different. The goal of this analysis is to make the necessary authorities aware of places that are very prone to flooding....

such that the necessary policies can be implemented. A very good study area would be North central Nigeria especially the confluence area where the niger and benue river actually meets. You can also use Bayelsa as a result of the flood that happened recently.
9. Change Detection Analysis:
This is a general analysis that can be performed using any kind of Project. It simply means comparing two analysed images of different periods together and assessing how much change has happened over time.
This is a general analysis that can be performed using any kind of Project. It simply means comparing two analysed images of different periods together and assessing how much change has happened over time.
So, you can perform a land use and land cover analysis for both year 2000 and 2022 and you do an analysis of the changes observed. You could also do something like "Pre-flood", "During the flood" and "After the flood" analysis for a flood risk assessment project.
The insights from these kinds of comparison are very insightful and revealing.
10. GIS in Healthcare:
What GIS in health can do is to help you note the places that certain diseases are prevalent and sometimes it can help with understanding "why" they are prevalent there.

For example GIS is very instrumental in mapping covid-19 - it helps you note how and where it started, how and where it is spreading to, & where it has spread to currently.Having this kind of insights can help you really make decisions that would be positive for the environment.
Tbh, these projects are all impossible without data and that why I said in my last thread on starting out in GIS that the crux of our work is data.
Literally, you can solve ANY kind of problem using GIS once you have your dataset and I literally mean any KIND of problem.

Also, these projects are just a tip of the iceberg as GIS offers much more than these. But these projects can be done by one who is ready to learn, understand and building something worthwhile with GIS.
All these projects can be done using either QGIS or ArcGIS. I curated this thread with beginners in mind. Yeah, so go for it as a beginner ✈️
