Loading temporary and permanent SOCET GXP software licenses

Joey Medina

Joey Medina

Prior to launching SOCET GXP, a license must be installed to unlock all software functionality. The license is provided as a text file that contains modules purchased.

Occasionally, a temporary license is required to test a workflow with the current version of SOCET GXP prior to transitioning to a permanent license.

When installing a new, permanent license to the GXP License Manager, the temporary license must be removed before the permanent license can be installed. This scenario is only necessary if the license is for the same version of SOCET GXP (i.e., SOCET GXP v4.0).

Use the following steps to complete the process.

Using the Jump to Coordinate tool in SOCET GXP

Use the Jump to Coordinate tool in SOCET GXP to navigate quickly from one location to another on a georeferenced image or map. Simply type (or copy and paste) known coordinates into the Jump to Coordinate: box — there is no need to specify the coordinate system or format type. SOCET GXP identifies the coordinate format based on the input and re-locates to the coordinates.

How to use the Jump to Coordinate tool

  1. Copy a coordinate, using one of the recognized formats, into the Jump to Coordinate: box. For example the coordinate,
    Zone 11N 479054.791139155920E3616167.689144271900N, matches the
    UTM format, Zone ##N ######E######N.
  2. Click the Go button, or press ENTER.
  3. The cursor location jumps to, and re-centers on that geocoordinate.

The Jump to Coordinate tool recognizes the following formats

Coordinate format Order Sample format
Geographic
  • Must be in latitude, longitude
  • The format must specify if coordinates are in the Northern, Southern, Western, or Eastern hemisphere. For example, latitude of 40.0 degrees is treated as 40.0 degrees North of the equator, while a latitude of -40.0 is treated as 40.0 degrees South of the equator. A longitude of 113.6 is treated as 113.6 East of Greenwich, while a longitude of -113.6 is treated as 113.6 West of Greenwich.

What to do with unwanted edge pixels

In a virtual mosaic, sometimes areas are obscured by overlapping images with void pixels. Void pixels are gaps between valid imagery and the actual image edge. These often are black but can be other solid colors. When displayed in a virtual mosaic, this kind of image can cause undesirable breaks in the coverage.

SOCET GXP provides functionality to make these void pixels transparent.

To control void pixel behavior:
  • In preferences, select Multiport > Virtual Mosaic Display panel, select the Hide Void Pixels check box to turn void pixels on, and the underlying images in the mosaic fill any black areas.

This process cleans up visible artifacts when the mosaic inputs have solid border pixel areas. If the void areas have a range of pixel values, set a minimum and maximum value. In most imagery, void pixels typically have the same minimum and maximum value set. For example, 0 is a very common pixel value used to represent transparency in imagery.

What to do when the mouse reaches the edge of a Multiport

The following tip is helpful to know when a user is annotating a polyline or using any tool such as the magnifying glass.

  • When approaching the edge of a Multiport, do not exit the current tool and roam to the next portion of the screen to continue the task.
  • While annotating or using any other tool and the mouse reaches the edge of a Multiport, a small dashed-line box appears.
  • After the dashed-line box appears, press the space bar to continue roaming in the direction of the mouse.
  • Press the space bar again to stop and continue the current task.
  • This prevents the user from having to add vertices and connect disjointed annotations that span more than the extent of a Multiport.

Copying a map from one Multiport to a different Multiport

When copying an auto-map from one Multiport to another, it may appear that a blank box copies instead of the map.

  • In this instance, the user has copied an auto-map image.
  • Copying an auto-map copies the function. The copying function reads the image metadata for the country code and creates an auto-map on the image it is pasted on.
  • If the pasted image does not have a country code in the metadata, the user can add it manually.
  • Maps are stored in the SOCET GXP® installation directory\Config\Country Maps.

Interpolation Methods

Pixel interpolation is the process of determining a value for an unknown or new pixel, based on known, and typically nearby, pixel values. SOCET GXP supports four pixel interpolation methods for zooming and for generation of reduced resolution datasets (RSets). When selecting an algorithm for use, consider the time constraints and image quality requirements of the products to be created.

The following are the supported methods in highest complexity (slowest) to lowest complexity (fastest) order: lagrange, bicubic, bilinear, and nearest neighbor. The term complexity generally corresponds to image clarity; however this depends greatly on the raster dataset being interpolated, and the type of analysis to be performed.

Guidelines for use:

  • Lagrange provides the best overall and best zoom-in quality
  • Bicubic is a good choice when zooming out, but upon zooming in, the smoothing tends to blur the image
  • Bilinear is a good option to use instead of the bicubic method if smoothing becomes a problem
  • Nearest neighbor should be used for speed and performance only, as the quality results in rough, staircase edge artifacts
  • Since bilinear is hardware accelerated, it provides good performance and decent quality
  • The size and shape of a feature in the image does not matter, use any interpolation method
  • For panchromatic or multispectral images, use any interpolation method
  • For SAR data, lagrange is ideal to use with SOCET GXP
  • More artifacts are evident in images with high contrast
  • RSet generation is performed once, therefore, it is worthwhile to use a more complex interpolation method if a group of analysts will be spending time zoomed out on an image
  • Zoom interpolation takes place each time you zoom in or out on an image; a faster algorithm is generally desirable
  • Remember, what you see visually is a tradeoff between processing time and quality

The default RSet generation interpolation method is nearest neighbor. For better quality, change the interpolation method to lagrange for RSet generation. To set preference, from the Workspace Manager, select Tools > Preferences > Load/Unload > RSet Generation, or select b. You can also change the interpolation method from the Multiport main menu; select View > Zoom > Zoom Interpolation.

SOCET for ArcGIS tips

Introduction

SOCET for ArcGIS, a SOCET SET module, adds stereo digitizing to ArcGIS; 3D information is captured directly in the ESRI® environment. Users see their familiar ArcMap® surroundings and Editor functions with a stereoscopic window for data collection, and SOCET SET manages image organization behind the scenes. Everything works in 3D, and photogrammetric expertise is not required. SOCET for ArcGIS works with the geodatabase, whether personal or multiuser, and handles versioning and topology. Users benefit from SOCET SET’s rigorous handling of airborne and satellite imagery – it embeds the photogrammetry into ArcMap.

Tips

Increase performance while loading graphics

Set the stereo viewport graphics mode to Limited. When set to Full, refreshing graphics will redraw every feature loaded in ArcMap, but when set to Limited it will only load features within the viewport.

Use the synchronize cursor functionality to navigate quickly to a feature in the stereo viewport from the ArcMap canvas

  1. Map an accelerator key in ArcMap to the synchronize cursor function.
  2. Toggle on ArcMap tools, press the accelerator key, and move to the feature of interest in the ArcMap canvas.
  3. The stereo viewport will navigate to the image automatically as the cursor moves.
  4. Once you have reached the area of interest, press the accelerator key again to turn off tracking and switch back to the stereo viewport to edit the feature.

Customizing the Multiport in SOCET GXP

Preferences may be created for individual users, entire organizations or multiple sites. The User Preferences file contains custom settings that control the appearance and operation of toolbars and Multiport windows, including size, shape, and location, as well as specific tools to include in each toolbar, which toolbars to display, and where the toolbars are placed within the Multiport. Preferences can be configured through the User Preferences file, or alternatively, as a shortcut, the easiest way to configure preferences for Multiport windows and toolbars is directly through the Multiport window. This allows the user to view changes dynamically on the screen rather than exiting the Preferences file menu each time a new preference is set. The following steps illustrate how to customize toolbars and Multiport windows in SOCET GXP via the Multiport window.

  1. Start SOCET GXP and load an image into the Workspace Manager
  2. Open the image into a Multiport window and associate an Overview window with that image. This is done by right-clicking on the image and selecting Open > Multiport and Overview.

    Note: A Multiport window is where users view their data and gain access to all of the exploitation tools necessary for analysis and product creation. The name Multiport was derived from the term “Multi-Purpose Viewport,” and epitomizes the extreme flexibility that the software offers. The Overview window is a Multiport window that has been scaled down in terms of size and functionality. A user may add or remove functionality to the Overview window.

    Multiport and Overview

    Multiport and Overview

  3. The image is now open in both Multiport and Overview windows. The next step is to resize the primary Multiport window to your satisfaction. This is done by dragging the corner of the Multiport window to a specific size. If you are running a dual display configuration, you may want to move the Multiport to another display.
  4. Repeat this step with the Overview window.
  5. The next step is to review the list of toolbars and activate or deactivate each checkbox based on need. To configure toolbars go to View > Toolbars > Customize. This allows you to add or remove individual pieces of functionality to suit your requirements. You may also experiment with the arrangement of each toolbar.
    To configure toolbars go to View > Toolbars > Customize.

    To configure toolbars go to View > Toolbars > Customize.


    Once the Multiport and Overview are sized and placed correctly and the toolbars have been customized to your specifications, it is time to update the Preferences file with this information.
  6. Click on View > Toolbars > Save Window Layout as Preference. You will notice several options available. First select either User or Common Multiport. If you would like all of the analysts who use SOCET GXP to use this window configuration, select Common to add to the common Preferences file. To activate individual preferences for each user, select User.
    Click on View > Toolbars > Save Window Layout as Preference.

    Click on View > Toolbars > Save Window Layout as Preference.

  7. Do the same for the User or Common Overview.
  8. Now the Multiport and toolbar configuration is part of your Preferences file. Future changes can be made from the Multiport window by selecting View > Toolbars > Save Window Layout as Preference.
