Data Layers

Once a project is activated, you can manage the visibility and accessibility of all your project data layers. Layer Settings are found on the upper-right side of the MultiViewer window.

Standard TI project have 4 layer groups: Cover Map, Thematic Layer, Vector data, Panoramic Images.

Cover Map: This group includes various layers used as a background and the basis of data visualization for your project work, which is typically orthophotos and OpenStreetMap

Thematic Layer: It includes different raster layers. E.g. a vector layer containing delimitation of the project area, etc.

Panoramic images: This group includes all panoramic image layers that contain detailed images for inspection

Vector data: This group includes all WFS vector layers (editable). It is used for observations.

Layer management

Layers are, by essence, datasets that can be managed individually. The layer set up is used to better organize projects. Each layer’s visibility and accessibility can be controlled separately by the checkboxes in front.


Cover Map

Left checkbox: turn on/off as main map (shown on the left if split mode is activated) Right checkbox: turn on/off as secondary map (shown on the right if split mode is activated) There can only be one main map and one secondary map activated at the same time, and this will activate split-screen mode. When in split-screen mode, an orange slider will appear on the screen so you can scroll between the two cover maps.

One cover map activated
Two cover maps activated (split screen mode)

Thematic & Vector Data Layers


These types of a layer can be turned on/off by ticking/unticking the checkboxes left to their layer names

Panoramic Images


Left checkbox: turn on/off the visualization of perspective centers on the cover map
Right checkbox: turn on/off a layer for spatial search

Workspace

A typical MultiViewer workspace consists of cover maps and viewports.
Cover maps show where you are and what you see (through OpenStreetMap, orthophoto)
Viewports (there can be max. 4 viewports open at the same time) present details of target area/object for inspection through images where registrations and quick notes can be made. For panorama images, multiple viewports can be open by holding CTRL + left-mouse-click on the image icon on the cover map.

Cover Map Workspace

Search: activate spatial search function by entering an address. The spatial search function is further explained in the structural inspection section

User Menu: activate or change projects, manage project data, and read more about MultiViewer

Toolbox Menu: access tools for inspection and workspace settings

Layer Settings: manage visibility and accessibility of your project data layers. A detailed explanation can be found in the layer management section

Notification Center: see all project activity history for your current MultiViewer session

Navigation panel: navigation in the cover map through on-screen buttons. A detailed explanation can be found in the next section, cover map navigation

Vector layer property window: manage and modify your inspection sweep plan and registrations, more details can be found in the structural inspection section

Geographical coordinates: the geographical coordinates of your cursor

Image View Direction: Showing the direction to which you are looking.

Cover Map Navigation

Once you enter a project, it is possible to navigate your view using both on-screen buttons and your mouse.

Reset to project origin: left click to reset project view (the view when you first activate your project)

The red color arrow shows the direction of the north. Double click on the icon will reset the view direction and tilt to its origin*
* Works only in 3D mode

Zoom in: left click on + sign

Viewport Workspace

To open a panoramic image, click the photo point. Holding down [Ctrl] while clicking on a photo point opens the image in a new window. You can open up to a total of 4 windows.

If you have enabled spacial search in the layer control, you can search the layer. Select [Alt + S] and then click anywhere on the map to open the nearest image with the center at that point.

If you have multiple searchable layers open (for example, two vintages of street photos), the closest image from each layer opens in its own window.
OBS: You can, in agreement with Hexagon, change the basic setting so that the search function is activated only by clicking on the map.


You can move the street photo window by dragging the move icon and you can resize the window by dragging pages or corners. Dragging the window beyond the edges of the browser window will lock the window and your screen will now be split into two windows. You can lock multiple windows. Use 'Swap Window' to release the window again.


Click 'Maximize' to get the street photo window swapped with the main window



If you click somewhere where there is no photo point, the panorama will close unless you have locked it by clicking Button pin so it turns red. The first window is locked as a starting point. Clicking Button Pin again closes the window.

To turn on/off vector layer visibility on the image.


You can view the current image location on the overview map.


You can adjust the image quality in the image and insert annotations.


The brightness and contrast for each window are adjusted by dragging the slider.

In 'Traffic mode' you can choose between 'Speed' and 'Quality'. In Speed mode, the image does not load at full resolution until you zoom in / out of the image. It allows fast switching between images in a continuous sequence. In Quality mode, the image is loaded at full resolution immediately.

In addition, you can draw/write notes . Select the note type and character with the left mouse button. Finish with right-click.
You can resize a text tag. First, right-click. Activate the note by left-clicking and adjust the text size by scrolling with the mouse wheel.
You can delete a single note by activating 'Delete note', holding down the left mouse button and dragging the cursor over the object. You can delete all notes by enabling 'Delete all notes'.
You can download the entire panorama.



Toolbox



Center overview map at current position
Especially useful when working on mobile devices. Remember that location must be turned on on the device.

Upload own photos/videos (GeoDropBox)

Requires separate agreement with Hexagon.

Measurement

There are functions for measuring horizontal distance, vertical height and horizontal area. Measurement in street images is associated with considerable uncertainty.
Therefore, the measurement function is only activated if agreed between Hexagon and the individual customer, and the function is only active within 20 m from the camera position…











If street photo access is available, you will get a warning in the bottom left corner that the measurement is uncertain. If street photo measurement is not available, you will be notified that metering is not allowed in street photos and the feature will not work.

The measurement is displayed in all open windows, but please note that the position of the measurement figure will be different in the individual windows due to the image orientation uncertainty.
Horizontal distance If the measurement includes only one line segment (horizontal distance by two points), both distance and now a compass direction are indicated for the line segment in the overview map (If you are working in 3D mode, distance is not indicated as a label on the overview map, but in a field at the bottom of the map window. Right-click to complete measurement).


Vertical Altitude First, activate a reference surface that defines how far away from the camera the altitude measurement is. If you do not use the reference surface, it is assumed that the measurement is done close to the camera, and therefore the specified height will be too large (right-click to complete measurement) .

Point to

Horizontal area Draws a closed polygon and the area is indicated in m² (right-click to complete measurement)


Delete all measurements



Save measurements: All active measurements are stored in a text file with the following syntax: [Geometry (x1 y1, x2 y2, x3 y3,….); length; area; height]


Green button to complete measurement used on mobile devices(on the desktop app it is an additional way to complete measurement). Red button to cancel measurements used on mobile devices(on the desktop app it is an additional way to complete measurement).



Before you print, you can insert a comment and your own logo. You can also adjust the image so that you do not get the thumbnail window in the print (check the box in 'Fullscreen only') or omit the indication of any measurements taken (check the box 'Hide last measurement').



Adjust the Workspace



Switch between 2D (Open Layers) view and 3D view map (Cesium) views. The default setting is the 2D view because the 3D view reduces performance for some users, but the 3D view selection option can be enabled by agreement with Hexagon. \ Switch to Full-Screen \ Enable Sync (see below).

Synchronizes the view when multiple windows are open. When Sync is enabled, the viewer automatically opens the street image closest to the center of the overview map. If multiple street photo layers are open, all open street photo layers are synchronized, and if you center a street photo at a point (right-click at the point), all open street photo layers are centered (center syncing only works at points near terrain).



Synchronization

You can synchronize the display of the open map and picture windows.

If you pan in the overview map , syncing means that:  

If you are panning in oblique photo , synchronization means that:

If you pan in a street photo , nothing happens. If you switch to a new street photo , syncing means that:

Thermal Inspection

To begin the inspection activate the thermal orthophoto layer in the Layer Settings under Covermap group.



































In Properties window select your vector layer (WFS).



































Properties window is divided into the following parts:

  1. Vector layer Name - List of available vector layers
  2. Filter - You can filter by different categories which observations to show in the observation list. Default value “Show all
  3. Observations list - List of observations
  4. Template - Before you started a new observation you can choose what kind of geometry you will use
  5. Add/Remove - By clicking Add you will add new observation in the list. Remove will remove selected observation from the list.



































To begin observation:
1. Click Add in Properties window
Message on the middle-top window will inform that observation mode is activated.
2. Mouse left click to start obeservation
3. Mouse right click to complete observation
By default new observation is selected, that's why it is in pink color and in Properties window under observations list it is marked in orange.

Observations Attributes

Each observation has its attribute table. To open the attribute table click on observation and the table will appear bellow Properties window. In this case, we have only two attributes “klasse” and comment:

Class types and names are flexible and can be modified to fit client needs. It is possible also to add more attributes to an observation.

Report

All observations made are automatically saved in an inspection report. Your inspection observations can be exported in Shapefiles (.shp). To download your observations as Shapefiles, choose the observation layer in the property window. Then click



To see your observations report, click on the Print inspection report button in the toolbox menu.
