This will have options to switch between assigned project coordinate reference systems and the World Geodetic System 1984 (WGS84) in various formats e.g. Decimal degrees or degrees,minutes & seconds. This may be useful for translating individual coordinates.

You can also right click on the map to show co-ordinates of the current location.

First tick the options, then select the units and if measuring time enter a vessel speed value. Once configured click points on the map and use right click to finish or minimize the Measure tool.

Drawing Tools

In the bottom left of the map, drawing tools can be opened and closed by clicking the pencil icon. Hover over each icon to see what shape they create. You can add a lebel before drawing by typing in the box. You can view the data in a table by clicking the table icon and download it by clicking download to get a geojson which can be used in GIS software.

To edit shapes e.g. adjusting nodes or moving objects, click the mouse pointer icon.

Adding Map Markers

Temporary map markers can be created using map pin icon. These could be placed manually on the map, specified by Kilometer Point (KP) along the current selected cable or pipeline Asset or by typing the coordinate values. You can switch between coordinate systems at any point by using the Show Coordinates tool. This may be useful for translating individual coordinates.

Please note that these only persist in a single IRIS session and will not be viewable by other users. To add a permanent layer contact the IRIS team.
