Since v.4.5

Introduction

Objects can store optional location coordinates. These coordinates can be delivered during import and later on used in various scenarios like display on a map, proximity search or pointcloud navigation. 

System provides translation mechanism that allows to provide the coordinates in any valid Spatial reference system. The data can be then fetched in the same or any other reference system.

You can use the https://spatialreference.org site to locate proper EPSG number. 

Data Import

Supported formats

Import of location data (point) is supported in the following formats:

Import domain (EID)

Below is a simple example of a domain that will be used to import coordinates from an Excel file. 

We have added external columns that contain location data (X, Y, Z). 

Open

These coordinates must be mapped in Coordinates section for every object class. In this case the name of the coordinates match, but it could be any name in the source package.

Open

Import profile

It's important to provide correct SRID (Spatial Reference System ID) during the import, if coordinates are imported. 

It must be a correct reference system that the data is represented in. It is not relevant for later use (e.g. when we need coordinates in another system, like WGS84) but its critical for proper registration of coordinates. 

Sample data package

This is a simple data package for import via Excel. Please note the class name (1), columns with coordinates (2) and a GUID/ID field for matching of objects (3).

System settings

The only system setting for this functionality is the default SRID that can be set in main section:

Accessing Data

Data is access by the system in various scenarios, but can also be accessed via system data API.

• api/object/json/108/608128?location=true&srId=4326

• api/perspective/metadata/json/11?childClassId=108&offset=0&limit=30&location=true&srId=4326

Two query parameters can be used to control location data returned:

Example of return data when SRID 4326 is given as argument:

Values are expressed in WGS84 (World Geodetic System) https://spatialreference.org/ref/epsg/wgs-84/

Example of return data when SRID 3011 is given as argument:

(Data is presented in EPSG projection 3011 - sweref99 18 00)

Proximity Search

planned

Ability to search object with one of the criteria being distance from given point or another object.

Display on a map

planned

Ability to display symbols representing objects in given map area. 

Using data for pointcloud navigation

 Viewing point-cloud requires a separate account at Navvis Ivion.

Configuration

Enable point cloud viewer in System settings:

Using the viewer

When the viewer is enabled, a new view type preference will become available: PC (PointCloud)

When this view type is enabled, a system will attempt to fetch Geo location of the object. 

If the location data is available, a system will search for a nearby site in Navvis system. When the site is located and opened, a navigation to scan position will be performed:
