Remote Sensing Certification

The Remote Sensing Certification is a free intermediate-level, 20-minute skill test from Science of Apps. It tests remote sensing — gathering information about the Earth from satellite and airborne sensors — for GIS analysts, earth scientists and surveyors. Covers the fundamentals (the electromagnetic spectrum, reflectance, passive and active sensors, platforms and the four resolutions), sensors and data (optical, multispectral, hyperspectral, thermal, radar/SAR and LiDAR, plus Landsat and Sentinel), image processing (corrections, band combinations, spectral indices and classification), and applications and analysis. Written to NASA Earthdata, USGS and ASPRS references for 2026. Score 70% or more on its 20 questions to earn a verifiable Remote Sensing Proficiency certificate (SOA-RSX). Every question is based on published standards and research — including Remote sensing backgrounder (NASA Earthdata), American Society for Photogrammetry and Remote Sensing (ASPRS), Copernicus Sentinel missions (European Space Agency) — and each answer is explained with its source.

Science of Apps offers a free Remote Sensing Certification, updated for 2026 and 2027. It measures fundamentals, sensors and data, image processing and applications and analysis and gives instant results with a shareable certificate.

Read the four skill areas on this page, then take the 20-minute test online — no fee, course or sign-up. You see every answer explained when you finish. Score 70% or more and you get a Remote Sensing Proficiency certificate straight away, on screen, as a PDF and by email, with a credential ID anyone can verify.

Yes. The questions are original scenarios written by Science of Apps, and each one is based on a public source you can read: Remote sensing backgrounder (NASA Earthdata); American Society for Photogrammetry and Remote Sensing (ASPRS); Copernicus Sentinel missions (European Space Agency); Landsat missions and data (US Geological Survey). The source is shown under each question and linked in the answer review. Science of Apps doesn't copy questions from other tests.

Four skill areas with five questions each, drawn from a bank of 10 per area so a retake brings new questions: Fundamentals (Spectrum, Sensors and Resolution); Sensors and Data (Optical, Radar and Satellites); Image Processing (Correction, Indices and Classification); Applications and Analysis (LandCover, Change and Accuracy). Every question is an original scenario written to the 2026–2027 standard, with the published source named under it.

GIS or geospatial analyst, Earth or environmental scientist, Surveyor or mapping professional, Agriculture or forestry analyst and Remote sensing student. It suits anyone who wants a quick, verifiable way to show Remote Sensing knowledge in 2026 and 2027, from students and career switchers to experienced professionals.

Remote sensing is the science of obtaining information about objects or areas from a distance, typically from satellites or aircraft, by measuring the electromagnetic energy they reflect or emit. It is used for mapping land cover, monitoring vegetation and water, assessing disasters and tracking environmental change over time.

Passive sensors measure natural energy, usually sunlight reflected by the surface or thermal energy emitted by it, so many depend on daylight. Active sensors, such as radar (SAR) and LiDAR, supply their own energy and measure the return, so they can operate at night and radar can see through clouds.

Yes. The test is online, in English and free everywhere — people take it from India, the US, the UK, Europe, Africa, Latin America and Asia-Pacific. Your certificate is dated with your own local date and can be verified from anywhere at scienceofapps.com/certification/verify/.

20 questions — 5 from each of 4 skill areas — with a 20-minute limit. You need 70% (14 of 20) to pass and 90% for distinction.

We rate it Intermediate: assumes hands-on experience in the role. It has 20 scenario questions — 5 from each of 4 skill areas — and a 20-minute limit. You need 70% (14 of 20) to pass and 90% for distinction.

Nothing. There is no fee to take a test, to receive the certificate, to have it emailed or to verify it, and no sign-up.

On our server, not in your browser. The answers never reach the page until you submit, so a certificate can only be earned by passing. Each certificate gets a unique credential ID stored by Science of Apps.

You see your score for each area and every question with the correct answer and why, with the published source behind it. You can retake after 30 minutes, and the retake draws questions you haven't seen yet.

No. Every certificate is dated, so it always shows when you passed. Retake a test any time for a newer date or a higher score.

Yes. After you pass, Add to LinkedIn opens the Licenses & certifications form with the certificate name, Science of Apps as the issuer, the issue date, your credential ID and the verification link filled in. You can also download it as a PDF or PNG, and it's emailed to you as a PDF.

Every certificate has a credential ID and a QR code. Scanning it, or entering the ID at scienceofapps.com/certification/verify/, shows the holder's name, the certification, the score and the issue date from our records.

No. They are Science of Apps' own assessments of applied skill. They aren't issued by a university or standards body, and they work best alongside a portfolio that shows the skills in real work.
