3D City Model Program

XEOS Imaging is deploying a program that aims to capture quality, high precision data of every medium and large Canadian cities. The data will be renewed every 2 years. By-products can be bought online on a 1 km² tile basis or citywide datasets.

3D City Model

The 3D City model is a realistic 3 dimensions representation of a city. The 5 cm per pixel resolution model and its accurate positioning enable the navigation throughout the city; measurements; mapping; and develop multiple 3 dimensions interactive applications.

XEOS Imaging’s program aims to cover all medium and major Canadian cities every two years.

Key Features

  • Image resolution: 5 cm for vertical images and 5.5 cm for oblique images
  • Tiled using a 1 km x 1 km tiling grid
  • Web application enabling the 3D navigation directly from any standard web browsers (Google Chrome, Mozilla Firefox, …)
  • File format compatible with Open Geospatial Consortium (OGC) international standards, ESRI (.SPLK) and many others.

LiDAR Point Cloud

Aerial LiDAR (Light Detection and Ranging) technology provides highly accurate 3D location of the ground and its features (trees, houses, powerlines, etc.). Each point of the resulting point cloud is classified to indicate whether it originates from the ground, the water, a three or a building.

Data acquisition is planned to ensure that each feature is scanned from two different directions in order to minimize obstructed areas without points.

XEOS Imaging’s program aims to cover medium and major Canadian cities and to update the data every two years.

Key Features

  • Elevation absolute accuracy: better than 10 cm (RMSE) on hard flat surface
  • Point density: 30 points/m²
  • LAZ v1.2 file format compatible with most geographic information systems (GIS)
  • Possible classification schemes:
    • L1: ground, water, unclassified
    • L2: ground, water, vegetation, buildings, unclassified
    • L3: ground, water, vegetation, buildings, poles, powerlines, unclassified
    • L1c, L2c, L3c: Classification scheme L1, L2 and L3 with colored LiDAR points based on the true orthophotos
  • Mapping projection: Modified Transverse Mercator (MTM), NAD83 CSRS
  • Vertical datum: CGVD28 HT2.0

True Orthophoto

Compared to conventional ortho mosaic where the image rectification is only done at ground level, every visible feature on a true orthophoto is perfectly rectified, whether it’s on the ground or above. Therefore, buildings, lampposts, poles, etc., are rectified in a perfect plan view.

XEOS Imaging’s program aims to cover medium and major Canadian cities and to update the data every two years.

Key Features

  • Image resolution: 5 cm in urban centers 20 cm elsewhere within city boundaries
  • Planimetric accuracy: better than 5 cm (RMSE)
  • Tiled using a 1 km x 1 km tiling grid
  • Geotiff (.TIFF) file format compatible with most geographic information systems (GIS)
  • Mapping projection: Modified Transverse Mercator (MTM), NAD83 CSRS
  • Vertical datum: CGVD28 HT2.0

RGB and Infrared Stereo Models

The XEOS aerial photos allows stereoscopic vision and mapping.  Their resolution is 5 cm and they offer a high x,y,z accuracy. The stereo models can be used in color RGB and infrared false color to facilitate the interpretation of vegetation.

XEOS Imaging’s program aims to update the stereo models of medium and major Canadian cities every two years.

Key Features

  • Photo type: Vertical (NADIR)
  • File format: TIFF RGBi compressed JPEG95
  • Photo resolution: 5 cm
  • Aerotriangulation accuracy: better than 5 cm in XY and 21 cm in Z (RMSE)
  • Forward overlap: 80%
  • Lateral overlap: 65%
  • Image orientation parameters: provided in Summit Evolution format (.smtxml)
  • Radiometry: RGB or infra-red false color
  • Mapping projection: Modified Transverse Mercator (MTM), NAD83 CSRS
  • Vertical datum: CGVD28 HT2.0

Oblique Aerial Photography

The XEOS oblique aerial photography allows for the vision at a 43° angle from the vertical. For each vertical photos, 4 oblique photos are taken: forward, backward, to the left, to the right. The image resolution is 5.5 cm closest to the aircraft.

XEOS Imaging’s program aims to update the oblique images of medium and major Canadian cities every two years.

Key Features

  • Photo type: 43° oblique
  • File format: TIFF RGBi compressed JPEG95
  • Photo resolution: 5.5 cm
  • Forward overlap: 80%
  • Lateral overlap: 65%
  • Image orientation paramaters: provided in Summit Evolution format (.smtxml)
  • Mapping projection: Modified Transverse Mercator (MTM), NAD83 CSRS
  • Vertical datum: CGVD28 HT2.0

Digital Elevation Model (DEM)

XEOS Digital Elevation Models (DEM) are generated based on high accuracy 30 pulse per square meter LiDAR data. They represent the bare-earth surface (Digital Terrain Model or DTM) or the earth surface including buildings, vegetation, etc. (Digital Surface Model or DTM) with an unparalleled level of details

Key Features

  • Data type: Digital Terrain Model (DTM) and Digital Surface Model (DSM)
  • File format: GeoTIFF
  • Altimetric accuracy: better than 10 cm (RMSE) in flat terrain
  • Resolution: 25 cm
  • Mapping projection: Modified Transverse Mercator (MTM), NAD83 CSRS
  • Vertical datum: CGVD28 HT2.0

XEOS 3D Browser

The XEOS 3D browser enables the display of the 3D Model as well as the true orthophotos and allows the navigation through the data in a direct line using any standard internet browser on any device. Basic tools enables distance, area and height measurements. It is also possible to draw points, lines and polygons. The drawn objects can be exported in a KML file.
