      EOxClient is a project to unify the needs of EO data visualization into a single configurable client.

      -

      It is currently being developed as an open source project by - EOX IT Services GmbH. We are a small, Vienna based company, - specializing in earth observation data and software needed to access it.

      General

      \ +
      \ +

      Click and drag the map to view the area of interest. Use the \ + scroll wheel or hold shift and draw a zoom box to zoom.

      \ +

      To switch the outlines or the preview layers on or off \ + expand the plus icon on the upper right corner.

      \ +

      Simply clicking on the map will open a window showing \ + information about the dataset(s) available at this position.

      \ +
      \ +

      Selection of Date and Time

      \ +
      \ +

      The begin and end date and time values are used for visualizing \ + datasets which lie within that time period. It is used for both footprint \ + overlays and also for the actual download.

      \ +

      The slider handles can be used to adjust the begin and the end date. \ + Alternatively, in the tab "Date/Time" the dates can be selected via a \ + date picking widget which can be activated by clicking in the date field.

      \ +

      Also the begin and end time parameters can be set in the according time \ + input fields.

      \ +
      \ +

      Selection of Bounds

      \ +
      \ +

      To subset the area of interest, use the "Bounding Box" \ + tab of the control panel. You can either manually set the values \ + of the bounding box, or you can use the "Draw BBOX" function.

      \ +

      Once the "Draw BBOX" button is clicked, the bounding box \ + can be drawed directly in the map. Alternatively it can be adjusted afterwards \ + in the according input fields.

      \ +

      The Bounding Box can be removed by clicking on the \ + "Clear BBOX" button.

      \ +

      If no Bounding Box is given, the map extent of the current \ + view is used.

      \ +
      \ +

      Download of Coverages

      \ +
      \ +

      When the "Download" button is clicked, the download dialog is opened. \ + It contains a list of all coverages that lie within the specified bounds \ + and time span.

      \ +

      All coverages that are checked will be downloaded upon a click on \ + "Start Download".

      \ +

      For Rectified Datasets, an optional size for each dimension can be \ + given. If left empty, the resulting image will not be scaled. Referenceable \ + Datasets cannot be scaled and the value in the size input fields only displays \ + their original size.

      \ +

      In the "Bands" dropdown box a number of bands can be selected, when \ + downloading the image. Multiple bands can be selected by pressing the \ + "Control"-key while selecting the entries.

      \ +

      When the button "Start Download" is clicked, all selected coverages will be \ + downloaded with the given parameters. For large downloads (larger than 1000x1000 \ + pixel) a warning will be shown.
