Types of Geospatial Data

  • Geospatial information systems (GIS) -The mapping of data inside visual representations is a function of geospatial information systems (GIS), as in the case of storm maps overlaying lightning strike potential zones. This makes it possible to visualize the place, the time, and prospective lightning strikes.
  • Vector and raster data are information stored combined with a geographic indicator as geospatial data. Points, lines, and polygons are used in vector data to represent buildings, cities, highways, mountains, and waterbodies.
  • Raster data comprises pixelated or griddled cells with row and column identifiers, which results in more intricate imagery like photos and satellite images. Both formats offer insightful information about a location’s numerous features.

     

    Examples of geospatial data

  • Vectors and attributes: Location-specific details, such as points, lines, and polygons.
  • Point clouds: a group of nearby recorded points that can be retextured to create 3D models.
  • Raster and satellite imagery: high-resolution aerial photographs of our planet.
  • Census data: released census information for the analysis of community patterns in specific geographic locations.
  • Cell phone data: Satellite-based call routing based on GPS coordinates.
  • Drawn images: CAD photos of buildings or other structures that provide both architectural data and location information
  • Social media data: Data scientists can examine social media posts to spot new trends.

Geospatial Technology & Python

Geospatial technology includes satellite technology for mapping and analyzing the Earth and gathering, storing, and organizing geographic data. It incorporates related technologies, including remote sensing, GPS, geofencing, and GIS. Python, a widely used programming language, is well suited for working with geographical data because it can accommodate both vector and raster data, the two formats in which geospatial data is generally stored. Utilizing tools like Fiona and GeoPandas, vector data may be handled. A program like an array can be used to manipulate raster data.

Its insights have an impact on issues like national Intelligence and resource management. The geospatial analysis enables the simultaneous examination of several occurrences, gathering pertinent information and empowering businesses to make wise business decisions. It assists firms in making more informed decisions by monitoring hundreds or thousands of events.

  • Utility companies can evaluate the efficiency of tens of thousands of kilometers of electricity lines.
  • By identifying nearby resources, wind, and solar systems can specify environmental conditions.

What is geospatial data analysis?

Collecting, integrating, and visualizing various geospatial data types are all part of geospatial data analysis. Making predictions based on patterns in the relationships between locations is done using it to model and portray how people, things, and phenomena interact in space. In other words, geospatial data analytics adds components of geography and time to data to make it more understandable. In the context of a visual representation of how the world looks, information that would be challenging to understand by reading line after line in a table or spreadsheet becomes much easier to understand. As a result, patterns including distance, closeness, the density of a variable, changes through time, and other interactions are more accessible for individuals to notice.

Geospatial data in analytics: 4 advantages

Trends in geography and time are more visually evident thanks to geospatial big data analytics than in a substantial raw data set. This provides numerous benefits over studying datasets without this kind of context. Here are 4 advantages of integrating geographic data in analytics as examples:

  • Recognizing geographical patterns and trends: Certain interactions and linkages cannot be comprehended without taking into account “where” (or “when”).
  • More significant segmentation potential: When location is included in an analysis, you may start to segment and filter depending on geography, which gives your study more specificity.
  • Modeling the real world: Since everything has a location, any analysis that ignores location already lacks an essential element. You may simulate the real world with geospatial data, frequently in real time.
    When you examine a phenomenon over time in a specific region, you understand better why it happens, where and when it does. Accurate predictions lead to better decision-making. This makes it easier to predict what will happen and when and where. You can plan how to respond to (or perhaps affect) upcoming occurrences.

the top 5 practical uses of geospatial data analysis

The growing integration of geospatial data into a variety of sectors and corporate operations shouldn’t come as a surprise. After all, it offers much more details and context than most other data types. Only a few commercial strategies now use geospatial data analysis techniques.

  • Visit Attribution- Calculate the number of customers who entered your store instead of just passing it by using property and mobility data.
  • Investment Research- In order to determine which companies are worth investing in, examine consumer behavior and movement patterns.
  • Competitive Intelligence- Based on their locations, determine which surrounding establishments and attractions are harming (or even benefiting) your stores.
  • Risk Assessment- The structure’s size, shape, location, use, and occupancy all assist insurance in determining how accident-prone it or its occupants are.
  • Consumer Insights- To carefully plan the locations and inventory of your business, look for trends in the other stores your customers frequent and the brands they choose to purchase.

The changing geospatial data analytics market & industry

Analysts forecast that between 2021 and 2026, the geospatial data analytics market will nearly double in size. Retail, private equity, insurance, utility companies, and governments are just a few of the many different industries of use. Geospatial data is used to foresee service outages, optimize maintenance, and enhance emergency response protocols. Self-driving cars and high-resolution bespoke maps might be developed as machine learning and geospatial data analysis converge. Geospatial data is typically visualized using maps, although the map utilized can affect the analysis’s outcomes. The methods for visualizing geospatial data will be covered in the following chapter.

Geospatial applications by industry

Governments can use weather, illness, and health data to inform the populace during emergencies and natural catastrophes. Electric utilities can foresee service interruptions and best use personnel and maintenance schedules. Insurance companies can predict risks properly and alert policyholders to probable problems. Agricultural and farm lenders can lower default rates and raise credit risk scores.
