Shape Files

Spatial information services are part of the NSTA system of record, and shape files are available directly from the NSTA GIS services.

However, it is possible for users to export specific content from the NDR Map.

This applies to map layers that are unique to the NDR, primarily for sub-layers relating to seismic surveys that can be used to display polygons for surveys that include post-stack, pre-stack or original seismic data.

Look for the export button next to supported layers (white triangle in blue box). Clicking this will download the selected layer as a GeoJSON file. (GeoJSON is an open standard format that represents geographical information in WGS84 Lat Long coordinates).

Other layers that are not generated from the NDR can be sourced from their source locations as indicated in the attribution button on the map (blue square with a white ‘i’ in the lower right corner).
