PCI Geomatica

PCI Geomatica 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 PCI Geomatica rather than just read about it. In short: PCI Geomatica is a remote sensing and photogrammetry desktop software package for processing earth observation data, designed by the PCI Geomatics company. The latest version of the software is Geomatica 2018.

Key takeaways

PCI Geomatica 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 PCI Geomatica to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of PCI Geomatica from memory before moving on to harder problems.

Reference excerpt

PCI Geomatica is a remote sensing and photogrammetry desktop software package for processing earth observation data, designed by the PCI Geomatics company. The latest version of the software is Geomatica 2018. Geomatica is aimed primarily at faster data processing and allows users to load satellite and aerial imagery where advanced analysis can be performed. Geomatica has been used by many educational institutions and scientific programs throughout the world to analyze satellite imagery and trends, such as the GlobeSAR Program, a program which was carried out by the Canada Centre for Remote Sensing in the 1990s. A very popular edition of Geomatica is known as Freeview, which permits users to load multiple types of satellite images as well as geospatial data that is stored in different formats. The software is available for download over the web, and has registered several thousands of downloads.

Image processing packages Geomatica is one of several software packages available to the educational, commercial, and military users. Other similar packages include Erdas Imagine, Envi, and SocetSet (or Socet GXP). Geomatica has also been compared to Envi and Erdas Imagine as it relates to orthorectification.

Educational institutions using Geomatica Over 2,700 educational institutions worldwide have used Geomatica as part of their Remote Sensing course delivery, some of which are listed here

Open Geospatial Consortium Geomatica includes a web coverage service interface that complies with the OGC Web Coverage Service (WCS) Interface Standard, which is a key area in which PCI Geomatics has contributed. Remote Sensing data providers distribute data in diverse formats, which makes sharing information across many different platforms challenging. WCS seeks to alleviate some of the data sharing challenges by publishing the geographic information and layers openly over the web.

Contributions to open standards Geomatica adheres to open standards to promote sharing and collaboration of earth observation data. An SDK that makes the PCIDSK file format available to the community is available.

Worked examples

Example 1 — a first encounter with PCI Geomatica

Start with the simplest possible case. Write down what PCI Geomatica 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 PCI Geomatica 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 PCI Geomatica 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 PCI Geomatica

In research: PCI Geomatica 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 PCI Geomatica 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: PCI Geomatica is common in secondary-school and first-year university syllabi. It links to neighbouring topics Photogrammetry software, Remote sensing software, so understanding it makes those chapters shorter.
In everyday life: Look for PCI Geomatica 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 PCI Geomatica in simple terms?

Why does PCI Geomatica 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 PCI Geomatica?

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.
