In an open source environment, remote sensing analysts perform techniques such as image classification, atmospheric correction and even radar decomposition.

A list of open source remote sensing software

The choices for commercial remote sensing software has increased over the years.

But what you may not know is the abundance of choice for open source remote sensing software.

The big plus:

They are for public use at no cost.

Without further ado, here is the big list of 13 open source remote sensing software packages.

1 The Sentinel Toolbox

The Sentinel Toolbox consists of 3 separate applications:

• Sentinel-1 Toolbox (SAR applications)
• Sentinel-2 Toolbox (High resolution optical applications)
• And Sentinel-3 Toolbox (High resolution optical applications)

Sentinel-2 has become the gold standard for open satellite data. In order to process the vast amounts of data collected by Sentinel-2A/2B, users can use the Sentinel Toolbox. One of the highlights of the Sen2cor plugin which allows users to correct for atmospheric effects and classify images.

If you download Sentinel-1 synthetic aperture radar data, you can process your data with the Sentinel-1 toolbox. For example, you can perform interferometry, speckle filtering and coregistration.

For your assistance, the open STEP Forum is a vibrant community of remote sensing enthusiasts to help answer questions you have.

2 QGIS Semi-automatic Classification Plugin (SCP)

4 ORFEO Toolbox (OTB): Optical and Radar Federated Earth Observation

The ORFEO toolbox was a cooperative project developed by France and Italy primarily built on the shoulders of the open source community.

This image processing library specifically aims at high spatial resolution data. ORFEO provides a wide range of remote sensing functions including radiometry, PCA, change detection, pan sharpening, image segmentation, classification and filtering.

One really interesting aspect of this software is the capability to do Large-Scale Mean-Shift segmentation (LSMC). This type of object based image analysis is a rare feature seen in software nowadays.

5 GRASS: Geographic Resources Analysis Support System

GRASS GIS is full of functionality. For example, it offers image classification, PCA, edge detection, radiometric corrections, 3D, geostatistics analysis and filtering options.

Gibson Ridge Radar Software

Another key feature of GRASS is the LiDAR processing and analysis. You can filter LiDAR points, create contours and generate DEMs. Next time you see a LAS file, see what GRASS can do with it.

6 PolSARPro

For synthetic aperture radar, you may want to look into PolSARPro. This software can handle dual and full polarization SAR from ENVISAT-ASAR, ALOS-PALSAR, RADARSAT-2 and TerraSAR-X.

There’s a wide range of tools like importing, conversion, filtering, decompositions, inSAR processing and calibration. Another neat part of this software is the graph processing framework where users can automate workflow. This functionality is similar to ArcGIS model builder and easy to set up.

Overall, PolSARPro is a very sophisticated piece of open source remote sensing software. You need to take a look at PolSARPro if you’re working with full or dual polarization SAR data.

7 Opticks

The neat part about Opticks software is the long list of extensions you can add. There are plugins for raster math, radar processing and hyper/multispectral.

Before downloading an extension, make sure to check the compatibility. Actually, you might have to scale back your Opticks version in order for the extension to work properly

8 OSSIM: Open Source Software Image Map

Not only has it been actively developed for almost two decades but interesting enough, it’s being funded through US departments such as in intelligence and defense.

OSSIM is a high performance open source remote sensing software application. Some of the key features is compatibility with more than 100 raster and vector formats and over 4000 different projections and datums. Ni usb 6501 manual.

It supports a long list of sensors but some may require additional plug-ins. If you need some remote sensing direction for high spatial resolution imagery, OSSIM might be the answer you have been searching for.

9 InterImage

InterImage is a bit different from the other open source remote sensing software on this list. It specializes in automatic image interpretation, which is pretty neat.

The core theme of automatic image interpretation is object-based image analysis (OBIA). This involves segmentation, exploring their spectral, geometric and spatial properties and then classification.

Radar Data Analysis

Although InterImage was developed in Brazil, documentation is available in English.

10 ILWIS: Integrated Land and Water Information System

For more than 25 year, ILWIS has been used from GIS enthusiasts. Actually, since its first release it has over 27,000 downloads. But it wasn’t until recently that it has become available for public use.

A dynamic and effective tool for data analysis and presentation.

Radar chart is a frequently used method for comprehensive evaluation, particularly useful for holistic and overall assessment through multivariate data. Its advantages lie in vivid visualization and ease of use. Through comparison and analysis, people can figure out their current situation: improving or falling behind. For those time-crunched managers, they can understand the situation at a glance. Generally speaking, there are 3 types of results in data analysis through Radar charts.

1. Vivid and visual description.
2. Realization of dynamic analysis.
3. Scientific depiction of industrial development track.
4. Effective mastery of dynamic data for relevant department.
5. Easy application and promotion, making the assessment concise, intuitive and fast, which will encourage people to pursue progress and excellence.

For example, we can compare students' test scores with the average score on subjects such as math, computer science, and biology. A radar chart has multiple axes along which data can be plotted. Each axis is a category. The data is shown as points on the axis. The points belonging to one data series can be joined or area so enclosed is filled. A point closer to the center on an axis indicates a lower value and vice versa. In some applications, low values may be more desirable than high values, e.g. price/earning, price/sales, price/book of stocks.

From the above radar chart example, we can figure out the following information:

1. Class 1 is excellent in computer science and didn't do well in Chemistry scoring only 68 points, the lowest among all subjects.
2. Lucy excels in study with all subjects above the average.
3. Tom should pay more attention to study since most of his scores are below the average. His strength is computer science in which he scores high and much higher than average.

You can draw a radar chart manually which is complex and time-consuming. Or you can let Edraw help you crack the hard-nut for you. It offers many pre-formatted templates so that users just need to make some modifications before use. Edraw doesn't require any drawing skill at all with the drag and drop interface.
