Spatial Layers
Overview
nVIRO supports integration of GIS layers, which can be displayed in a site plan and in nSITE Explorer.
Managing Spatial Layers
To manage spatial layers, navigate to Admin > Lookups > Spatial Layers.
Use the sort buttons or filters at the top of each column to locate a specific spatial layer. When using a filter, the list dynamically updates to display all spatial layers that match the entered value.
Click a layer name to open it for editing. To create a new layer, click the Add New Spatial Layer button. To delete one, click the vertical ellipses (⋮) at the far right of the row, then click the Delete button.
nVISAGE dynamic spatial layers are not displayed in this list. For more information, see the Dynamic Spatial Layer Configuration (from an nVISAGE Report) page.
Editing Spatial Layers
Fields available for editing on the Edit Spatial Layer page are described below.
To save changes, click the Save button. To cancel changes or return to the list after saving, click the Cancel button.
Field | Description | Notes |
Layer Type | The spatial layer type. Options include:
| arcgis layers appear as in the image below:  Example arcgis-type layer For more information on Esri ArcGIS feature layers, see ArcGIS Online. xyz layers appear as in the image below: Example xyz-type layer For more information on Esri Tile layers, see OpenLayers. |
Layer Name | The name for the layer. | The layer name must be unique. |
Group Name | The name of the group name in which the layer will be placed. | Layers are organized within groups in the map interface. |
Display Order | The layer’s position within its layer group. | The display order determines the order in which layers appear on the map. For example, a layer with a display order of 10 will appear above a layer with a display order of 5. Base layers must have a display order of 0. |
Base Layer | Indication of whether the layer is a base layer. |
|
Base Type | For base layers, the base layer type. | This field does not apply to feature layers. The following base types are often associated with ArcGIS base layers:
|
Layer is Visible by Default | For base layers, indication of whether this layer is the default one shown when the map first loads. | This field does not apply to other layer types. |
Layer is Available in Site Plan | Indication of whether the layer is available in site plans. |
|
Layer is Available to Authorized External Users | Indication of whether the layer can be enabled in site plans by authorized external users. | If separate versions of nSITE Explorer are installed for internal and external users, this setting also determines whether the layer is available in the public-facing version. This option only applies if the Layer is Available in nSITE Explorer checkbox is selected. |
Preset Layer(s) | Layers that can be collectively toggled on or off in a site plan. |
|
Layer is Searchable on Site Plan | For SQLSpatial layers, indication of whether layer attributes can be searched. | This field does not apply to other layer types. |
Intersect Warning | The warning message displayed to users and included in the intersect report when a selected feature intersects with this layer. |
|
Layer is Available in nSITE Explorer | Indication of whether the layer is available in nSITE Explorer. |
|
Layer URL | The URL associated with an arcgis, Bing, or WMS layer. | This field does not apply to other layer types. Entering a value in this field auto-populates the Layer Legend URL field with the correctly formatted ArcGIS value. The system validates the Layer URL format based on the selected layer type. For more information, see the next section. |
ArcGIS Mapservice Layer ID | For acrgis layers, the layer value associated with the source layer in ArcGIS. | This field does not apply to other layer types. Entering a value in this field auto-populates the Layer Metadata URL field with the correctly formatted ArcGIS value. |
Include Intersect Fields | Indication of whether the intersect fields are appended to the intersect query to define what information is returned from the service. |
|
Intersect Fields | Fields to display on the site plan when the Inspection Intersections tool is used to display layer properties. | Multiple fields must be separated by commas. Enter an asterisk (*) to include all fields. Including invalid fields will prevent intersections from being returned. For arcgis layers, available fields are shown in ArcGIS under the Fields section of the layer details. |
Layer Intersect Metadata URL | The URL associated with displaying metadata for the layer. | This information is automatically generated by a stored procedure upon save and cannot be edited manually. |
Layer Opacity | A decimal value between 0 and 1 representing the layer’s transparency. | A value of 1 displays the layer fully opaque (solid), while lower values increase transparency. The default is 1. |
Spatial Layer Validation
When creating or editing spatial layers, the system validates the Layer URL format based on the selected layer type. Valid formats for each type are listed below.
Layer Type | URL Format |
|---|---|
arcgis (or arcgissecure) | URL ending in “/export” |
arcgisfeature | URL ending in “/FeatureServer” |
Bing | Any valid URL |
SQLSpatial | N/A, field hidden |
WMS | Any valid URL |
xyz | URL ending in “/tile/{z}/{y}/{x}” |
If the URL format does not meet the requirements for the selected layer type, an error message appears.
