1. Fixed the bug affecting the resizing of panels under the latest release of Firefox. However, we still don't know why it did not work for the release 1.5 and later.
2. Due to the licensing limitation, we can not redistribute the ASTER images in its original formats. However, users can download its product, such as NDVI.

1. To be added

1. A new approach is used to generate grid points from images, which will not cause displancement of grid points with respect to the center points of pixels. In the grid points file, the 1st column is longitude, 2nd column is latitude, and the columns 3 and above are values for each band depending on the type of image. For example, to download the entire 7 bands of a Landsat image in a grid format, choose 'Original Image' from the Product Type drop down menu after selecting a Landsat image, then select the radio button 'Text', and click 'Download' button. If you choose a product such as NDVI, the grid data downloaded will be longitude, latitude and a 3rd column for NDVI.

   Due to the signigicant size increase (5-6 folds) in converting binary image to a grid format, the grid image is (ZIP) compressed, and needs to be extracted first.

   Note: the reflectance values for the original images have been multiplied by 400. For example, a value of 200 gives a reflectance of 0.5 or 50%. Also the index values, such as NDVI or Green DNVI, should be subtracted by 100 and then divided by 100. For example, a value of 150 in NDVI product corresponds to the actual value of 0.5.

2. The track of AeroCam flight and images it acquired during 2005 campaign was added as a GIS layer (AeroCam 2005). The AeroCam flight track is defined as a serious points, each of which is denoated with an image id. You can also request AeroCam image through DNGP interface by access it through AOI menu (for registered users and registration is free). Remember to include the image ID and the year in your request.

1. The resize for panels, such as image list or GIS layers, does not work under the latest version of Mozilla Firefox 1.5 or later. It works for the earlier versions of Firefox and for the Internet Explorer. We do not know the causes yet and we are working to address the issue.

1. You can now download an image in a text format, where the 1st column is longitude, 2nd column is latitude, and the columns 3 and above are values for each band depending on the type of image. For example, to download the entire 7 bands of a Landsat image in a grid format, choose 'Original Image' from the Product Type drop down menu after selecting a Landsat image, then select the radio button 'Text', and click 'Download' button.

2. Animation of a series of images. To access, click the icon with two arrowed half circles, which pops up the slide control panel. To create an animation:
   1. Display the first image;
   2. Click 'Add' buton on the slide control panel;
   3. Repeat the previous 2 steps to add the rest of images.
   4. Click 'Delete' to delete the last image just added.
   5. Click 'Clear" to clear the animation or start a new animation.
3. You can send request for AeroCam and AgCam image acquistion. Must be a registered user to access. Once login, under the AOI menu, there are two links, one for the AeroCam and the other for the AgCam. Follow the instruction then.

1. There are difference in defining a line return among UNIX/Linux, Windows and Mac OS; Unix/Linux uses line feed '\n', Mac uses carriage return '\r', while Windows uses both (line feed and carriage return). The format of grid data is for Windows platform. If you open the grid data on a Linux platform, you will see ^M at the end of each line.

1. Add a new function for making and displaying slides of a series of images. To access, click the icon with two arrowed half circles, which pops up the slide control panel. It works by adding the image showing in your current window into a slide queue.
2. Under IE, there is a period of freezing when the website is first loaded; the issue is not found for Mozilla type of browsers, e.g., Netscape, Mozilla, or Firefox. Removing span blocks that were used in formatting each individual image under the List of Images seemed to mitigate the problem, even though the initial loading speed is still slower in IE than in Mizilla types of browsers. We still don't know why.
3. Due to ever increasing number of images, we have to limit the numer of image items to be downloaded at one time to improve the performance. Therefore, only images of the selected remote sensor are listed at one time. Different sensors can be selected from the sensor list and the list of images for the selected sensor will be updated.
4. Cosmetic changes to panels for the GIS layer and the Image List.
5. Mouseover MODIS 250 meter images will not trigger drawing the footprint, which covers the entire UMAC region anyway.
6. The interface was rewritten to accommodate various resolutions of a monitor.
7. Codings were simplified.

1. Metadata does not render in IE. This is caused by the security settings of IE limiting the access to the metadata style sheet on a different domain. To fix it, go to Control Panel -> Internet Options -> Security -> Custom Levels (with Internet icon highlighted) -> Miscellaneous -> Access data sources across domains. It is usually disables, enable it.
2. Metadata style does not apply in Mozilla or Netscape. This is caused by the security feature that Mozilla won't load XSLT stylesheets from a different domain. It is fixed by using local domain in metadata style sheet

1. The entire Javascripts codes were reviewed and modified towards efficiency.

2. The server side image processing programs, mostly written in C/C++, were rewritten in a more consistent way.

3. The image and user managements were reviewed and modified towards efficiency and code clearness.

1. The layout of the interface has been modified to fit into most of the monitor resolutions.

2. A context area is added just above the map window. The information in the context area are dynamically updated according to actions a user takes. The information include the action taken, what you are currently viewing, and what can be done next, and etc.

3. Improved the tooltips.

1. The check mark for the selected image becomes unchecked once the image is zoomed in.

2. Query returns only county and state information even when additional layers selected.

3. The progress bar was not properly renewed, preventing the time step from being re-initialized after the progress bar was stoped, especially under Mozilla type of browsers.

1. When you mouse over through the image list, the boundary of a partial covered image is displayed on the map.

2. The layout of the main page is changed.

3. When you create AOI or delete AOI through menu items on top menu bar, the updated AOI list is displayed automaticaly in main page.

4. A text area is displayed on the bottom of map frame which display short message to users. For now, we only display action information when users zoom in, zoom out or pan on the map. We will display more information on this area according to users' needs.

1. The major change: Instead of autoloading the most recent satellite image as a certain scale is reached, what will be auto-displayed is the high resolution (up to 1 meter/pixel) digital photograph (DOQ) that is hosted at TerraServer USA.

2. Instead of using two scale bars (one for miles and one for kilometers), there is only one scale bar showing miles, and the other one showing scales in terms of meters per pixel.

3. The default mode for showing an image is the true color band combination.

4. Some minor bugs are fixed.

5. The code has been cleaned and is tighter than before.

1. The new version currently does not function properly under Mac, and we are working on this issue.

2. Under windows Internet Explorer, when you drag the panel around, you may notice some panel components floating above the rest of the panel components. This is a known issue for the Windows Internet Explorer and we are working towards an alternative.

1. Fast: The DNGP version 3 discards the use of Java Applet which is slow and has been used in all the previous versions for zoom in and out, pan, and query. Now we use lightweight Javascript to furnish these functions. As a result, an image will show up much quicker than it used to be.

2. Appearance: The new version also features a modulized interface design resembling the Windows enviornment that most of our users are used to. There are five independent panels for map, reference map, image list, layers, and controls; each of them can be independently moved, resized and minimized. Also there is a status bar showing progress for "impatient" users including ourselves.

3. Interoperability: From the DNGP version 3 website, you can seamlessly access high resolution aerial photogran (DOQ) and digitized paper map (DRG), both of which are actually hosted at TerraServer USA. However, instead of searching around, you can display a DOQ photograph in your familiar DNGP environment plus numerous vector layers at your hand to be overlaid.

1. Redesigned Map window (panel). Your mouse movement over the Map panel is continuously tracked and its location (latitude and longitude) is updated just below the map. Quickly print what you see and download what you see. You can find these two quick access buttons on the right side of Map panel.

2. Expanded layers now contain all kind of information on census, land cover, water, trace metal, and etc. And best of all, we keep adding.

3. More remote sensing sensors. We are now archiving data from SRTM (Shuttle Radar Topography Mission), and ASTER (Advanced Spaceborne Thermal Emmision and Reflectioin Radiometer) on Terra, in addition to the traditional MSS, TM and ETM+ from LandSat series.

4. Improved control panel. You can change band combination for multispectral images and color scheme for single band images, alter brightness, choose various remote sensing products, and download images and products in GeoTIFF format.

1. The new version currently does not function properly under Mac, and we are working on this issue.

2. Under windows Internet Explorer, when you drag the panel around, you may notice some panel components floating above the rest of the panel components. This is a known issue for the Windows Internet Explorer and we are working towards an alternative.

3. There will always be some issues unknown to us now, please report to us once you find one.
