OversightML Imagery Toolkit v1.4.0rc1

This release contains a preview of the new map tiling capabilities to be introduced in v1.4.0. The changes include giving the GDALTileFactory the ability to create orthophoto tiles using a grid of locations computed using the SensorModel created from the image metadata. These functions can be combined with the WebMercatorQuad tile matrix set to provide support for integrating imagery into a variety of map visualization applications. Preliminary performance tests have not shown issues so long as the imagery has an existing set of pre-generated overviews and auxiliary files with pixel statistics.

Limitations:

  • Only PNGs: This implementation only provides support for PNG formatted output images.
  • Local DRA: The dynamic range adjustments are calculated on a per-tile basis instead of using global image statistics.
  • Simple Elevation: This code does not currently use an external digital elevation model to provide elevation information for points chosen inside a tile.

New Dependency:

  • OpenCV has been added to provide the core image warping required to produce orthophotos.
