ImageStation: Production Mapping and High Volume Photogrammetry Software
Unparalleled Processing, Accurate Results for CAD and GIS-Based Workflows
The ImageStation software suite enables digital photogrammetry production workflows, including project creation, orientation and triangulation from aerial and satellite imagery. It provides stereo GIS feature collection and editing, digital terrain model (DTM) collection and editing, as well as orthophoto production and editing. ImageStation is specially designed to move large quantities of raw spatial information to an actionable or exploitable format for government, commercial photogrammetry, and mapping agencies worldwide.
Large orthophoto projects, such as the National Agriculture Imagery Program (NAIP), generally use multiple terrain elevation datasets with different formats and coordinate systems. Generating such large elevation surfaces is labor-intensive and time- consuming. ImageStation’s simplified project creation and highly automated processing gets your projects up and running quickly.
Early verification of orientation and triangulation quality means less labor lost trying to fix problems later on in the process. GIS and CAD-based 3D feature collection and editing saves time by working directly with the native database. Digital terrain model (DTM) collection and editing ensure the accuracy of your elevation data with a few simple validation steps.
Dense matching with a Semi-Global Matching (SGM) algorithm creates highly dense, highly accurate point clouds from your imagery, eliminating the need for more expensive data collection flights. Streamlined, multi-user orthophoto production using aerial frame, ADS line scanner, UAV, and satellite imagery puts the power of state-of-the-art technology to work in creating planimetrically and aesthetically accurate orthophotos.
Using ImageStation within the GeoMedia context facilitates the creation of continuous, topologically accurate, and attributed map layers stored in a variety of open formats. This integration further enhances the process of creating and/or updating your GIS using photogrammetric techniques which directly store your data as an asset within a corporate database.
Your ability to capture and maintain data is easier with ImageStation Stereo for GeoMedia. It focuses on GIS workflows, which allow you to create intelligent geographic features rather than merely place lines. Emphasis is placed on ensuring the accurate collection of the geospatial data the first time and reducing the need for time-consuming cleanup or editing after data collection.
