![]() Perform bundle block adjustmentīundle block adjustment is the process of refining image orientation and geometric parameters by solving a mathematic model established from a set of control points. Once a mosaic dataset is authored, the next step is to perform bundle block adjustment. For more information on raster types, see What is a raster type.īelow is a footprint view of a mosaic dataset created from UAV images. Add the data using the Add Rasters to Mosaic Dataset tool, choosing the appropriate raster type for the data.Create a mosaic dataset using the Create Mosaic Dataset tool.The ortho mapping workflow starts from authoring a mosaic dataset from the images of your study area. Generate a point cloud from a mosaic dataset.Ī mosaic dataset is the data model in ArcGIS that is used to manage and process a collection of images such as satellite images, aerial images, scanned aerial photos, and UAS and UAV images.There are six tasks in the ortho mapping workflow: Below is a diagram of the high-level workflows for generating ortho mapping products. #Add multiple images mosaic pro erdas softwareThe software can generate ortho mapping products such as orthomosaics, DTMs, and DSMs from the bundle block adjustments. In cases where high geometric accuracy of the output image mosaic is needed, you should derive high-resolution DSMs and DTMs from stereo pairs.ĪrcGIS Desktop supports bundle block adjustment of satellite and aerial imagery. The digital elevation model (DEM) used in the image orthorectification plays a very important role in the geometric accuracy of the final image mosaic, especially for areas with diverse terrains. Geometric accuracy and reduce the misalignment, bundleīlock adjustment, also known as image triangulation, needs to be performed Images come with geometric errors, as wellĪs misalignments between adjacent image scenesĭue to systematic and nonsystematic factors. When many images are required to fully cover your study area, you need to mosaic these images Model (DTM), and a digital surface model (DSM), from a set Generating ortho products, such as an image mosaic, a digital terrain
