GeoMedia

GeoMedia is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand GeoMedia rather than just read about it. In short: Hexagon Geospatial's (a division of Intergraph Corporation) GeoMedia Professional is a geographic information system (GIS) management solution for map generation and the analysis of geographic information with smart tools that capture and edit spatial data. GeoMedia is used for: creating geographic data; managing geospatial databases; joining business data, location intelligence and geographic data together; creatin…

Key takeaways

GeoMedia belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect GeoMedia to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of GeoMedia from memory before moving on to harder problems.

Reference excerpt

Hexagon Geospatial's (a division of Intergraph Corporation) GeoMedia Professional is a geographic information system (GIS) management solution for map generation and the analysis of geographic information with smart tools that capture and edit spatial data. GeoMedia is used for: creating geographic data; managing geospatial databases; joining business data, location intelligence and geographic data together; creating hard and soft-copy maps; conduct analysis in 'real-time'; base platform for multiple applications, geographic data validation, publishing geospatial information and analyzing mapped information. The GeoMedia family consists of 17 applications tailored for regional and local government, national and federal government, military and intelligence, utilities, communications, photogrammetry and transportation markets. The system does not rely on proprietary data, but rather accesses and uses data sources directly or data that adheres to open standards such as those defined by the Open Geospatial Consortium and others. It is an enterprise-based system, providing an organization the ability to access, conduct analysis and distribute information through the organization or over the Web. GeoMedia includes the following Windows desktop software:

GeoMedia Viewer, a free application which allows for map display, simple analysis and output of GeoMedia GeoWorkspace data. It is intended as a distribution mechanism for data created using GeoMedia products; GeoMedia is licensed under three functional tiers: GeoMedia Essentials, allows for dynamic, complex and ad hoc query and perform basic spatial analysis of vector geospatial data across various data sources as well as create layered maps; GeoMedia Advantage, adds to the functionality of Essentials by adding terrain and grid functions which will allow for additional analysis on digital elevation models, flow analysis and contour line generation; or GeoMedia Professional, includes added capability to collect features, linear referencing management, quality assurance and validation tools as well as database schema mapping and management. Besides the desktop platform, there are also server-based GeoMedia products as well as GeoMedia products for various mobile devices to include smartphones and tablet computers. Optional extensions can be acquired separately to increase the functionality of GeoMedia.

History GeoMedia was developed under the Intergraph Corporation. However, on December 2, 2013, Intergraph Security, Government and Infrastructure split its divisions and rebranded as Hexagon Geospatial. The GeoMedia software and resources are currently hosted on the Hexagon website.

Worked examples

Example 1 — a first encounter with GeoMedia

Start with the simplest possible case. Write down what GeoMedia claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to GeoMedia before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about GeoMedia ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of GeoMedia

In research: GeoMedia appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses GeoMedia in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: GeoMedia is common in secondary-school and first-year university syllabi. It links to neighbouring topics GIS software, so understanding it makes those chapters shorter.
In everyday life: Look for GeoMedia outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is GeoMedia in simple terms?

Why does GeoMedia matter?

Because it connects several computer science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study GeoMedia?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
