Some characteristics of Satellite images such as: digitally format, production up-to dated data, wide viewing angle swath width , multispectral as well as multi temporal and revisiting time of data acquisition with high speed on data transformation make those be considered as valuable information on the natural resources management. Based on proposed methodology, some pre-Processing practices which involve geometric and radiometric correction were implemented by applying Pci Geomatica 9.

Image processing was conducted on the next step based on Object Oriented method by applying eCogenation software. Followed step related to classifying of SPOT image based on proposed classes 18 classes: irrigated agriculture, dry farming area, bare soil, apricot orchards.

To set the Elevation Information From the list under the elevation file you selected, select the DEM layer. Click Setup. These layers will be used in the atmospheric correction.

Slope The Slope layer contains values between degrees. These values are calculated as the slope of the plane formed by the vector connecting the left and right neighbours and the vector connecting the upper and lower neighbours of the pixel.

Aspect The Aspect layer contains values from relative to the top of the image. Aspect at a point is calculated as the orientation of the plane formed by the vector connecting the left and right neighbors and the vector connecting the upper and lower neighbors of the pixel: the angle between north top of image and the projection of the normal vector of this plane onto the horizontal plane.

Sky View The Sky View layer is calculated with a ray tracing program and ranges from 0 to 1, with 1 indicating a full hemispherical view. The Sky View factor determines the fraction of the hemispherical diffuse sky flux and determines the fraction of radiation reflected from surrounding mountains onto the considered pixel. Shadow The shadow layer is a binary file where shadow pixels are coded with 0 and sunlit pixels with 1.

It includes self shadowing and cast shadow effects. Self shadowing consists of pixels oriented away from the sun with slopes steeper than the solar elevation angle. The cast shadow calculation is based on a ray tracing algorithm and includes shadow regions caused by higher surrounding mountains.

The Elevation Data Setup dialog box closes and you are returned to the Atmospheric Correction Configuration dialog box. The Band Setup dialog box contains a table where you specify the relationship between the sensor band numbers and the channel numbers in the input file.

You can also specify the input file bands you want to correct. There are a number of calibration files provided with the software. Once the sensor type is selected, the available calibration files are listed for that sensor. There is also a Browse option to select a different file, if one has been provided with the scene. NoteIn most cases, the standard calibration files should be used for reflectance images.

The Atmospheric Definition parameter lets you choose a condition to determine the coefficients used during the correction process. The choices are dependent on the sensor type and scene conditions.

The Condition parameter lets you choose from a list of atmospheric conditions at the time of acquisition. Thermal Atmospheric Definition allows you to choose an atmospheric condition to determine the coefficients for creating a temperature map image.

The file choices are dependent on the sensor type and scene conditions. Because you are not processing a thermal band, this option can be ignored. The Solar Calculations dialog box opens. This allows you to automatically calculate the solar zenith and azimuth by entering the date, time and position of the image.

The azimuth, when in reference to the South is usually called the bearing. If the sun is East of South, the bearing is positive, else the bearing is negative. TermThe Solar Zenith Angle is the angle between the line of sight to the sun and the local zenith any point directly above the ground site. See Figure 2. The figure below is a graph for the image region at latitude 47 and longitude By lining up the date May 22 on the x-axis and time on the y-axis, you can calculate the sun azimuth for this region.

Using the graph, you can see the sun azimuth changes throughout the day and over the span of a year. Figure 2. The Visibility box lets you enter a constant visibility value in kilometers.

About this Training Guide The scope of this guide is confined to the core PCI software applications included in the Geomatica suite; however, some remote sensing concepts are reviewed in the modules and lessons.

The following modules are included in this course: Module 1 – Image Classification Module 2 – Performing Atmospheric Correction Module 3 – Spatial Analysis in Focus Module 4 – Publishing Map Projects Module 5 – Working with Geomatica Modeler Each module in this book contains a series of hands-on lessons that let you work with the software and a set of sample data.

Geomatica II 2 PCI Geomatics Geospatial Data Structures Data for the geospatial applications are stored in complex files that are often incompatible with specific software packages and operating systems.

PCI Geomatics 3 Figure 1 GeoGateway in Geomatica With GeoGateway technology you can work through a mapping project by assembling raster and vector data from different sources and different file formats without having to preprocess or reformat the data.

Figure 3 Geomatica Toolbar When you pass your mouse over a button on the toolbar the name of the application appears as a ToolTip beside your mouse pointer. Menu bar B. Toolbar C. Maps and Files tree tabs D. Work area E. View area F. NoteThe data listed in the Files tree is stored in the source file on your system hard disk. Working with Geomatica Project Files Focus project files.

Starting Your Work In the lessons that follow, you will have an opportunity to work with several Geomatica applications and to carry out several tasks using Focus. Supervised Classification Supervised classification is more closely controlled by you than unsupervised classification.

Supervised training requires you to construct your information classes from a priori knowledge of the data, such as: What type of classes need to be extracted? Lesson 1. Starting a New Classification Session To begin working on this module, make sure Focus is open on your desktop. On the Project toolbar, click Open File. A File Selector dialog box opens.

The Session Selection dialog box opens. This channel will store your classification results. In this lesson you: Started a new classification session Initialized an unsupervised classification Ran a classification and reviewed the report Lesson 1.

To set up the reference image Turn off the visibility of the Classification Metalayer. Turn on the visibility of the Classification Metalayer. The Channel Setup dialog box opens. The Aggregate dialog box opens. Under View Controls, select Current Classes. This displays the classes currently selected in the Input Classes list. The name and color changes will be written to the output file. The metalayer is removed. In this lesson you: Combined classes into new aggregate classes Table 1: Remaining Aggregate Classes Aggregate Class Input Classes 32 10, 11, 13, 15, 17, 22, 24, 26, 28 33 1, 5, 6 34 3, 4, 12, 14, 16, 18, 19, 20, 21, 23, 25, 27, 29, 30 Lesson 1.

Initializing Supervised Classification Like unsupervised classification, supervised classification is initialized as a session in Focus. The Session Configuration dialog box opens. To configure the session In the Description box, type Supervised Classification.

Beside the Description box, click Add Layer. The Add Image Channels dialog box opens. Specifying the Reference Image Recall that supervised classification requires you to rely on your own pattern recognition skills and a priori knowledge of the data to help Focus determine the spectral signatures for classifying the data.

Next, you will select three bands to be displayed as a reference image in the Focus view area. This channel will store the classification results. To create a new class In the Name column, type bare soil. Collecting Training Sites After naming bare soil in the Training Site Editor, you can use the Focus Editing Toolbar commands to draw training sites for this class over the image in the Focus view area.

On the Editing toolbar, click the New Shapes arrow. Select Polygon. Click the reference image within the bounds of the subject area where you want to start the training area outline. Use your mouse pointer to draw a line to the next point of your polygon and click once. Trace the outline of the polygon by clicking at the end of each line segment as shown in the figure below. Add three new classes called planted fields, urban and forest.

To erase training sites Use your mouse to trace around the training area you want to erase from the image. Double-click to erase. You should see an irregularly shaped lake with an island. Changing Training Site Colors Focus automatically assigns colors to new training classes. In the Training Site Editing table, click the color sample for the training site you want to change.

A color adjustment dialog box opens for the training site you selected. Signature Statistics The Signature Statistics dialog box displays the number of samples in the training area indicating whether you have collected enough pixels to accurately represent the land cover.

The Signature Statistics dialog box opens. Next, you will display a histogram to check the reliability of your training sites. To create a histogram for a training site: From the Tools menu in the Training Site Editor dialog box, select Histogram. Alternatively, you can select a class, right-click and select Histogram. The Signature Separability dialog box opens. The Scatter Plot dialog box opens.

For each class, select both the Plot Mean and Plot Ellipse option. In the Training Site Editing table, under the Threshold column for the urban class, type 2.

The Supervised Classification dialog box opens. In the next lesson you will examine tools for post-classification analysis. The classes are loaded under the Assign Reference Class to Sample section. A false color composite is loaded in the view area.

Next, a random sample of points will be generated for the dataset. The Generate Random Samples dialog box opens. Zoom into the image at a resolution of or higher. Continue to assign classes to the remaining points in the Random Sample List. In the Accuracy Assessment dialog box, click Save.

A New Item Detected dialog box opens. Click Save. The Accuracy Report dialog box creates three types of reports: Sample Report Listing: Shows which samples are correctly classified.

To produce an Accuracy Report On the Accuracy Assessment dialog box, click Accuracy Report. The Accuracy Report dialog box opens. Click the Error Confusion Matrix tab. Click Generate Report. Click the Accuracy Statistics tab. In the Output Ports section, clear the check mark from the Viewer-Grayscale option.

Select the Viewer-PCT option. A pseudocolor image opens in the view area. Improvement for Data Analysis There are several ways atmospheric correction of satellite images improves data analysis: The influences of atmosphere and solar illumination are removed or greatly reduced.

Sensors that are currently supported in Geomatica are listed in Table 1. The Atmospheric Correction Configuration dialog box opens. Set the Height to 0. For the Units, select Kilometers. Lesson 2.
