VerticalGeo is one of the few companies that can extract airfield features from stereo imagery to create 3-D airfield maps.  We use a system that includes BAE’s Socet GXP and Socet for Arc tied to ESRI’s ArcGIS Desktop 10.x software to create 3-D features.  We also use ESRI’s Data Reviewer and other tools ensure attribute data and topology are accurate.

We have been producing 3-D airfield maps for the past 2 years and have collected 36 airfields 3all across the globe.

We provide deliverable products in shapefile, ESRI file geodatabase, or Google Earth (KML) formats.  Shapefile are the most common open data standard mapping deliverable, while the ESRI file geodatabase is probably the most widely used.

Here is a screenshot of an airport terminal and parking ramp that we extracted using stereo imagery.

VerticalGeo has been tasked to produce a comprehensive vertical obstruction dataset that includes power-related and cultural data layers using targeted feature extraction over focused AOIs.  This project utilizes open source information and current vertical obstruction database to target feature extraction using imagery over the selected AOIs.  VerticalGeo has verified the information of over 500,000 known obstructions and located over 300,000 previously unknown vertical obstructions since 2015.

We have finished an update of the vertical obstruction database in the following areas:
– Northeast US                                   – Hawaii
– Libya                                                  – Morocco
– Algeria                                               – Tunisia
– Indonesia                                          – Thailand
– Bolivia                                                – Paraguay
– Mozambique                                    – Malawi
– China                                                  – India
