Geo queries

Stanag On Demand server allows you to query a mission database for different types of geographical information. You can efficiently process vast amounts of ISR data using various query criteria.
For example :

• Find all missions that were recorded during the selected time period at the specific location.
• Find all flights over a specific area.
• Find a video taken at a specific location.
• Find out when the UAV / plane was in the area of interest.
• Etc.

Area Of Interest (AOI)

Before we perform any query we have to select the desired area of interest:

• Filmed area - query filmed area information (based on corner points)
• Frame center trail - query center of FOV trail
• Platform path - query platform's swath path

Of course, you can only get results when the relevant metadata is present in a mission database. For example, if there are no corner points (offsets or full) it is impossible (without calculating them from FOV and other data) to get the filmed area information.

Query types

Filter missions

This query type can be used for finding missions that have video content geographically related to the specific area of interest:
Perform query by drawing one of the following shapes on a map:

• Polygon (intersect)
• Rectangle (intersect)
• Point (include)

To find missions that contain a video taken at the particular region of interest, select Filmed area query type in the map menu.
Use Drawing tools on the map to select the desired area. You can draw a rectangle, polygon or just set a marker point.
Your web client will now query the server and return a list of missions that covered the selected area. Mission panel should now only contain the relevant missions.
You can add additional criteria to your search, for example, restrict the search to a specific time range.

Query one particular mission

This query type can be used for a relevant part of video using geo coordinates.

• Polygon (intersect)
• Rectangle (intersect)

It is effectively a video coverage query - an extremely useful tool is a map query that graphically shows where exactly in the video clip you can find the places selected on the map. As shown below, the place selected on a map had been only filmed at the beginning of the mission, so if this is the only location we're interested in, there is no need to go over the entire video.

Show filmed area

The area polygon is calculated from corner points (offsets or full).

Show area of interest (heat map)

The heatmap emphasizes the area the operator focused the camera most of the time.

Show path

This query shoes a swath path built from the platform's coordinates.
