The program is proposing to create a new file for your geometrically corrected images. Your cache administrator is webmaster. Click Ignore Zero Stats, so that the pixels filled with zeros are excluded when statistics are calculated for the output file. The image viewer is split into 3 panes: The largest, right-hand pane shows a portion of your image at full resolution (1 screen pixel = 1 image pixel).

Usually the goal of geometric correction is to obtain an error within plus or minus one pixel of its true position(see Figure 9.4.3). a. Provide a short Name for your project that will be shown in lists of similar project files. Your cache administrator is webmaster.

Note that in the Corrected Image pane, much information has already been filled in for you. To edit a GCP value, click on it and you will be able to enter new coordinates in the upper section of the GCP Collection window. After the geometric correction has completed, you can: Close the Geometric Corrected Image Production window; request a Residual Report by selecting Reports from the Processing Step pull-down menu; do a final Related Content Join the 15-year community celebration.

Try to make sure all areas of your image are represented - i.e., near the corners and near the middle. The Open Image panel lists images that you have previously worked on in this OrthoEngine project. Now you can specify the size of the pixels in the corrected image that will be created. The values in the Residual column are the combined x- and y- residuals.

The tangent correction for an optical mechanical scanner is a type of system correction. When you close the Polynomial Properties window, a GCP Tool Reference dialog opens (you can also get this dialog by clicking on the cross hair symbol in the GeoCorrections Tools window). the RMS is the overall error estimate for this set of points. The system returned: (22) Invalid argument The remote host or network may be down.

You can also adjust how your uncorrected image is displayed by clicking on the RGB Mapper and/or Enhancements buttons. Now position the cursor exactly over the identical location in your geocoded image. Highlight the Vector Segment you want to use and then click Load & Close. When the Project Information panel appears, fill in the following: Give your project a Filename.

This will transfer the georeferenced coordinates for your point into the GCP Collection pane. Reload the page to see its updated state. Click Accept. Select the appropriate UTM Zone and Row for the area of your image.

To do this, click on the Select icon (the arrow) in the GCP Tools window, then move the arrow to the desired GCP and drag the GCP to the correct location. Choosing Ground Control Points (GCPs) Go into the class folder for this lab and display band 2 of the image tmAtlanta.img as a gray scale image (you can do this To evaluate the accuracy of the current polynomial, refer back to the GCP Collection window: Examine the RMS (root mean squared) error estimates. By convention, this is usually an even divisor of 100 that is the same, or slightly smaller than the resolution of the uncorrected image. (Note: although the output pixel spacing may

The system returned: (22) Invalid argument The remote host or network may be down. There won't be an exact match for each point because a variety of imprecisions in the way the satellite acquires the image, the way maps are made, and in the method To give you an idea of how accurate the conversion process will be, the program uses the polynomial transform to calculate the proposed location for each of your points. it.

The bottom-left pane shows an overview of your image. road network), or a good map covering the area in your image. All the adjustment procedures require that you have a number of sites on the image with known coordinates. You then shift the pixels in the image to fit those coordinates. Select the image that you want to correct: Click on the Open a new or existing image button.

Click on Use as GCP. Compare tmAtlanta_1st_near, tmAtlanta_2nd_near, and tmAtlanta_3rd_near. Which image or images seem to provide the best spatial portrayal of locations relative to the SPOT image? (Bring up the Spot image in a viewer, Part II. Error Checking As you entered your GCPs, you probably had some moments of doubt as to whether your locations for the GCPs were correct. You are not alone
