| Web-based Geo-Referenced
Image Manager (WebGRIM) |
|
WebGRIM is an advanced software application that
allows users and operators to control all aspects of
imagery collection and post processing. WebGRIM, combined
with a GI-Eye system, collects
high resolution imagery (taken from the air or the ground)
and precise camera location and orientation information.
This data is stored in an Oracle spatial database for
quick and reliable access to virtually unlimited amounts
of imagery. WebGRIM provides the tools to display, sort,
manage, and use that imagery for photogrammetry and targeting. |
| |
Key features |
|
- Quickly locate and manipulate collected imagery.
- Map-based displays provide context for data
allowing the user to rapidly locate the data of
interest.
- User-friendly interface allows the operator
to control camera collection parameters on-the-fly,
e.g., shutter speed, gain control, and data collection
rate.
- Near real-time orthorectification and mosaicking
of collected imagery makes situational awareness
and target identification quick and easy. Users
can generate their own maps on demand from the
collected data.
- Point-and-click targeting—using proprietary
high-accuracy NAVSYS algorithms—provides
target quality coordinates from aerial imagery
at the click of a mouse. For aerial and terrestrially
collected imagery, triple-shot targeting can provide
similar coordinates.
|
- WebGRIM mapping software is compliant with OGC standards
allowing the system to display third-party maps, imagery,
and live data (such as weather radar) obtained over
the Internet. Additionally, WebGRIM could act as a
Web Mapping Server (WMS) allowing third-party applications
to seamlessly import data from WebGRIM.
|
- Web-based system allows collaboration between multiple,
simultaneous users, and requires no software be installed
on client computers.
|
- WebGRIM, when coupled with the GI-Eye InterNav™ software, could use local-area DGPS data from
a customer-run reference station, or wide-area data
obtained over a network, to provide ultra-accurate
imagery registration.
|
- Auto-DEM module will allow the generation of precision
digital elevation models from collected imagery.

In this image, WebGRIM is displaying
the “footprints” (magenta)
of images from an aerial collection. The
background imagery in this case is being
downloaded from the USGS over the Internet.
The user has further narrowed the area-of-interest
by drawing the red box. The raw images
within this box are shown at the bottom
of the screen.

The image above shows the user performing
single-shot targeting. After selecting
a raw image from the map display, the
user clicks on any point on the image.
Targeting-level accuracy coordinates are
generated for that point.

Shown above is a small, user-built
mosaic of UAV imagery (color) overlaid
on historical (black & white) USGS
imagery. To build a mosaic, the user
has only to identify the geographic area
of interest.
