Can I process aerial photos scanned from prints?
Yes. There is a pre-processing step in EnsoMOSAIC, that co-registers scan-outs into a common image coordinate system using corner or side fiducials of the photos. After co-registering the processing is as with any other images. The scan-outs can be from a simple table scanner or from a high-end professional scanner. Back

Does EnsoMOSAIC georectify also individual images?
Yes. In addition to a georeferenced orthomosaic EnsoMOSAIC calculates also individual orthoimages. These can be exported as an option, as individual orthos are not normally needed in applications. Back

Is there a university license available?
Yes. There is a non-profit non-commercial license available for strictly educational use only. The educational license allows collecting and processing imagery for internal use, but distributing imagery or orthos for third parties is not allowed. Back

Is there an evaluation license available?
Yes. The evaluation license allows you to process a real image block of your own, or test the sofware with an example data set. The evaluation license can be downloaded after contacting us. Regret, there is no evaluation license compiled of EnsoMOSAIC 3D. Back

Does EnsoMOSAIC process satellite images?
No. EnsoMOSAIC is designed to process images collected with any frame camera, for example any digital camera images and photos from aerial film cameras. These images are in central projection and the entire image exposed at once. Most satellite images are formed of line scanned data thus not suitable for EnsoMOSAIC. Similarly, data from aerial line scanners, such as AISA or CASI, cannot be processed with EnsoMOSAIC. Back

Is EnsoMOSAIC suitable for UAVs?
Yes.
Software: EnsoMOSAIC software can process images collected by UAVs (Unmanned Aerial Vehicles) equipped with any compact or SLR digital camera, such as Canon ixus or Pentax A30.
Hardware: EnsoMOSAIC imaging system is suitable for UAVs that have sufficient payload capacity, but the system is not applicable for the lightest UAV-category. Back

Can I do 3D data acquisition in EnsoMOSAIC?
You cannot do stereo acquisition in the core EnsoMOSAIC software, but it is easily carried out with EnsoMOSAIC 3D, which directly reads EnsoMOSAIC blocks and sensor models. It is also possible to export EnsoMOSAIC blocks for 3D processing in external applications, such as ArcGIS Stereo Analyst. Back

Can EnsoMOSAIC handle partitioning of long and narrow datasets?
Yes. EnsoMOSAIC handles splitting the orthomosaic into manageable pieces (tiles). Common tile sizes are 2km x 5km or 10km x 10km, depending on the user application. The tile size is depends on image resolution and size and division of map sheets. Back

Can EnsoMOSAIC process thermal images?
Yes. EnsoMOSAIC handles also single band images. All depths are supported from 8 to 32 bits. Also 2 and 4 bits are accepted but there is hardly enough information content worth processing. Back

Are EnsoMOSAIC UAV licenses upgradeable to the full version?
Yes. Both UAV licenses are upgradeable to higher ones for clients with software maintenance agreement. The license fees already paid are compensated for the upgraded license. Back

Does EnsoMOSAIC do image stiching?
No. Image stiching means joining images together by non-photogrammetric means. EnsoMOSAIC does not perform simple image stiching. Instead it carries out image orthorectification, which corrects for lens distortion, aircraft orientation and ground topography. The resulting orthomosaic is measurable GIS-ready image map, instead of a simple combination of images. Back

Are elevation models accurate?
EnsoMOSAIC outputs elevations from two processes:
1. EnsoMOSAIC calculates elevation models within aerial triangulation and uses those internally in orthorectification. These models are good to describe elevations generally.
2. EnsoMOSAIC 3D calculates elevations that are accurate at pixel level. If error sources are controlled these models and contours are good for cadastral surveys and topographical mapping.

Does EnsoMOSAIC only work with vertical imagery or can it also handle oblique imagery?
EnsoMOSAIC can triangulate also oblique imagery, providing that there is sufficient image overlap and reasonably accurate initial orientations available. Back
