3D Geo Analytics

Project Background

Creation of Three Dimensional Enterprise Geo Analytics

By using high resolution aerial images from UltraCam, Pixelo created a 3D Geo Analytics of existing public and private infrastructure for 20 municipalities in France.

In 2018, a Belgium based Aerial Photogrammetric company, engaged the services of Pixelo in order to have the entire existing infrastructure mapped and created into a Geo Analytics system.

Pixelo performed mapping of 20 municipalities covering 180 sq.km.

The mapping was carried out using high resolution UltraCam images and involved preparation on base map at a scale of 1:1000. Once the base map is created the data is converted into an ESRI geodatabase. Once the geodatabase is created, required topological relationships are built and the data is made into a Geo Analytics system.

Activities are performed by Pixelo

1. Base Map Preparation:
The Aerial images are oriented using the Image Station SSK photogrammetry suite. Using the stereo methods, the following classes of features are captured.

  • Public Limits: Roads, Road Dividers, Side Walks, Public Parking Space Alignments, Public ways, Alleys, Green Areas, Railways
  • Private Limits: Private Domains, Private Parking Spaces, Private Gardens
  • Hydrography: Canals, lakes, pools
  • Woods: Tree lines and Isolated trees, Forest Areas
  • Street Furniture: Poles, Flag posts, Lamp Posts, Man holes, Pylons, Post Boxes
  • Buildings: Buildings, Roof ridges, Terrace Lines
  • Traffic Information: Painted Arrows, Traffic Signals, Pedestrian Crossings

2. Geodatabase Design
An Enterprise Geodatabase is designed to cater the objective of the system. The database is created in Oracle 10G and the GIS data is migrated to the Geodatabase. The attributes such as geographic areas of the Private Properties and Public Properties are created. The database enables Municipalities to manage the Public resources, infrastructure and improve the Revenue collection.

By choosing Pixelo as their outsourcing partner, the customer is clearly able to demonstrate the advantage of Pixelo’ skilled man power and cost effective solution, thereby saving a lot of money in terms of not having to tie up customer’s internal resources.
