IMPORT_ONLINE

Updated

IMPORT_ONLINE

The IMPORT_ONLINE command imports data from some types of streaming online data sets. The following parameters are supported by the command:

  • SOURCE_TYPE - Type of online source. Supported values are:
    • EPT - streaming Lidar using Entwine interface
    • EsriRaster - ESRI Image or Mosaic server
  • NAME - name of the online source
  • BASE_URL - specifies the base URL for the source

Cloud Connection

If a connection to a cloud service (like AWS) is required for the source, the parameters below can provide information about that service:

  • CLOUD_TYPE - cloud type. Currently, only AWS is supported, as in CLOUD_TYPE="Amazon's AWS S3".
  • CLOUD_IS_REQUESTER_PAYS - specifies if the cloud is a Requester Pays cloud. Defaults to true, so use CLOUD_IS_REQUESTER_PAYS=NO to disable.
  • CLOUD_KEY1 - first access key (Public Key for AWS S3).
  • CLOUD_KEY2 - second access key (Private Key for AWS S3).
  • CLOUD_FOLDER - folder where the file exists in the cloud (Bucket for AWS S3).
  • CLOUD_LOCATION - location where the folder exists (Region for AWS S3).
  • CLOUD_FILE - the name of the file as it exists in the cloud.

Specify Bounds for Layer

  Use the parameters below to define the bounding box to import from the source:

  • ADDRESS - address to download data near. Use with RADIUS to specify the bounds with an address and radius rather than a specific bounding box.
  • RADIUS - radius in kilometers around ADDRESS to search.
  • LAT_LON_BOUNDS - specifies the bounds to import in latitude/longitude degrees relative to the WGS84 datum. There should be 4 values in a comma-delimited list following the parameter name. The values should be in order of westernmost longitude, southernmost latitude, easternmost longitude, northernmost latitude.
  • LAYER_BOUNDS - specifies that the import should use the bounds of the loaded layer(s) with the given filename. For example, to import to the bounds of the file "c:\test.tif", you would use LAYER_BOUNDS="c:\test.tif". Keep in mind that the file must be currently loaded.
  • LAYER_BOUNDS_EXPAND - specifies that the operation should expand the used LAYER_BOUNDS bounding box by some amount. The amount to expand the bounding rectangle by should be specified in the current global projection. For example, if you have a UTM/meters projection active and want to expand the bounds retrieved from the LAYER_BOUNDS parameter by 100 meters on the left and right, and 50 meters on the top and bottom, you could use LAYER_BOUNDS_EXPAND="100.0,50.0". You can also specify a single value to apply to all 4 sides, or supply four separate values in the order "left,top,right,bottom".
