Sites Type

This type holds a list of locations on Earth. The sites can be defined in different coordinates reference systems (CRS). They are converted into the destination CRS when added to a product.

Add Sites to the Asset Library

Add Sites from Placemark File

Sites can be imported from the placemark files SNAP uses. Either the text or the XMl files. The styling of the placemarks is stored with sites and applied when added to a product later.

Add Sites from CSV File

A CSV file can be used to import Sites into the Asset Library too.

This CSV file has only minimal requirements to the content format. Each line of the file represents a site. Each site must provide the following columns in this order:

• Name: The name of the site.
• X coordinate: The X coordinate of the site.
• Y coordinate: The Y coordinate of the site.

Lines can be marked as comment by starting this line with the # character and thus be ignored. The columns must be separated by one of four separator characters.

• comma ','
• tab '\t'
• space ' '
• semi-colon ';'

It is configurable when importing the sites which separator is used. If the CSV separator is used within one of the column values, then it must be enclosed in double quotes.

Optionally each site can be amended with additional information. Additionally, a description, the CRS and the styling can be provided as fourth, fifth and sixth column.
The description provides a short descriptive text, the CRS column provides the coordinate reference system in which the coordinates are given. The CRS must be specified as EPSG code (e.g., EPSG:32645). If the CRS is not explicitly defined, then WGS-84 is assumed. The style column can be used to change how the sites are displayed.

The styling follows a CSS format. There are 6 attributes available.

• symbol - The symbol to mark the coordinate. Can be one of plus, cross, star, square, circle or pin.
• fill - Defines the fill color of the symbol. The color can be provided in hexadecimal format (e.g., "#FFFFFF") or given by comma-separated values, such as "255,255,255".
• fill-opacity - Defines the opacity of the fill color. Between 0 an 1.0.
• stroke - The color of the outline. The color can be provided in hexadecimal format (e.g., "#FFFFFF") or given by comma-separated values, such as "255,255,255".
• stroke-opacity - Defines the opacity of the stroke color. Between 0 an 1.0.
• stroke-width - Defines the width of the outline stroke.

Example of a CSV file using a comma as separator:

Add Sites to a Product

When adding sites to a product you have several options on how these are added.

• Only include within bounds - Only sites in the geographical bounds of the product will be included.
• Add to pins - This will add the sites to the pins of the product.
• Add to GCPs - This will add the sites to the GCPs of the product.
• Add to a vector node - This will add the sites an existing vector node. You can choose which one from selection box.
  • Vector node -  The sites will be added to the node selected.
• Create a new vector node - This will create a new node and add the sites to it. You can specify the name of the new node.
  • Name of node - Specify the name of the new node.
