3D Analysis

Forget visualizations. GIS software systems should keep up with the 3D world we are in right now by performing 3D analysis. Doing so can help everyone assess our 3D world, especially in the areas of water quality, population, biodiversity, etc. Also, this trend takes us a step closer to 4D analysis.

AI and Machine Learning

AI and machine learning can understand what your complex data cannot. For instance, it helps locate natural clusters based on attribute similarities and spatial distribution, categorize a huge amount of virtually sensed data, and gather data from various sources, scales, and formats to train solid spatial prediction frameworks. Keep in mind that GIS does not just attempt to understand the world, it also forecasts its future and helps make it a better place to live in.

According to GIS Professional’s survey, the major challenges of GIS users are data accuracy (32%) and efficient data management (31%). Moreover, 12% see open source and open data both as a challenge and a trend, while 8% noted location privacy as a concern to be cautious of.

The survey participants also raised concerns about GIS employment by users who do not have basic knowledge about the software and the soaring cost of GIS tools. Open-source data and programs have resulted in the rise of user groups who know the benefits of GIS but do not have a deep understanding of how to use it correctly. This new group paves the way for a new market for GIS software providers.

• The GIS industry reached a value of $11.6 billion in 2021.
• The GIS market is expected to grow by $9.7 billion by 2025.
• It is projected to grow at a CAGR of 16.2% until 2025.
• GIS data’s biggest usage portion is navigation.
• GIS software use has grown due to the development of smart cities and widespread urban planning projects.

• Engineering. GIS generates data for the building of power plants, communication network towers, and other public infrastructures such as roads and waterways.
• Retail. The retail industry uses GIS to locate the best area to build a new store. On the other hand, marketers use it to recognize which locations require a certain type of marketing and which stores can have the potential for maximum revenue. Supply chain personnel can also use the software to map out the most efficient routes to improve logistics.
• Disaster management. GIS is used by governments across the world to effectively respond to natural calamities such as hurricanes. Meteorologists also use it to pinpoint and predict weather and climate trends.
• Science. Biologists turn to GIS to observe animal migration and examine similar phenomena. Meanwhile, geologists can outline geographical features for natural resource management. GIS tools also help marine ecologists study marine ecosystems and create different types of nautical charts.
