Metric Zone Definitions

The zones for Atrius Insights follow the GeoJSON specification. All zones should be polygons; other types of geometry types will be rejected by the API. Zone features should include the following properties (note IDs will be provided by related APIs):

  • zoneID – Unique Zone Identifier (Only required on update)
  • site_ID – Site Assignment
  • floor_ID – Floor Assignment
  • name – Zone Name
  • enterTrigger – Action Zone Enter flag (Not required for metric zone)
  • exitTrigger – Action Zone Exit flag (Not required for metric zone)
  • dwellTriggerMS – Action Zone Dwell Flag (Not required for metric zone)
  • messageContent – Action Zone Message Info (Not required for metric zone)
  • lvl – Level Identifier, pulled from floor lookup

Geo-rectified Map Tiles

Atrius Insights uses base map services that follow the industry standard tiled slippy map format. Both the ArcGIS Server and the OGC implementation of this standard are supported.

Requirements of the map tiles inclue:

  • The SRID for the map service should be Web Mercator (EPSG 3857)
  • We provide some flexibility with the URL template to support ArcGIS Server or OGC
    • OGC: http://host-url/mapservice/{z}/{x}/{y}.png
    • ArcGIS: http://host-url/mapservice/{z}/{y}/{x}
  • Atrius Insights supports ArcGIS Online authentication or MapBox token based authentication
  • Atrius Insights requires additional zoom levels in addition to the zoom levels defined in the standard. Here is a list of all the zoom levels that Atrius Insights requires:

Floorspace Background Image Requirements

When associating a raster image via Atrius Admin (UI or API) as a background to a Floorspace, the image file must meet the following requirements:

  1. Image Type – raster (.png or .jpeg)
  2. Image Size – Minimum 2732 pixels in one dimension
  3. Meters/Pixel – The ratio of meters to pixels must be provided with each image
  4. Spatial reference information for the image.
    • As part of the geo-reference service provided by Acuity, spatial reference information for the image will be generated and will be compatible with GDAL and ArcGIS. The projection for this image will be Web Mercator (EPSG 3857) and will exactly match the map service.
