Opticks, a Free & Open Source Remote Sensing And Imagery Analysis Software
If you’ve used commercial tools like: ERDAS IMAGINE, RemoteView, ENVI, or SOCET GXP, then you need to give Opticks a try. Opticks is a free & open source remote sensing and imagery analysis software that supports the following file formats: NITF 2.0/2.1, GeoTIFF, ENVI, ASPAM/PAR, CGM, DTED, Generic RAW, ESRI Shapefile, HDF5, AVI, MPEG, JPEG, GIF, PNG, BMP.
Optics general features :
- Load large imagery (>16 GB).
- You can pick if the data is loaded entirely into RAM or processed iteratively off the disk based upon your needs.
- You can view metadata from the image without loading the image.
- Choose a single band/frame/channel from the image to display as either gray-scale or colorized using color maps/tables. You can visually create a custom color table.
- Choose any three bands/frames/channels from the image to generate a false or true color image. Actually any bands/frames/channels from any loaded images can be used if they are the same size (same # of x,y pixels).
- Support for complex data and the ability to display either the Phase, Magnitude, In-phase (I) and Quadrature (Q).
- Choose from a variety of histograms when colorizing a chosen band/frame/channel: linear, exponential, logarithmic and histogram equalization. Also select the end points using: raw values, percentage, percentile and standard deviation.
- Create an animation that will flip through all of the bands/frames in an image and then export it as a video (MPEG or AVI).
- Link two or more views and have the pan, zoom, and rotate actions in one mirrored in the others. This can be done with or without georeference information.
- Band Math allows you to perform mathematical calculations using the bands/frames in an image to generate a 2-D result. For example, NDVI (Normalized Difference Vegetation Index).
- Convolution allows you to specify a convolution filter (e.g. moving window kernel) to an image to generate a new image.
- Georeference an image. You can use the built-in georeference algorithms or write your own extension to work best with your imagery.
- Wizard Builder. Drag-and-drop functional blocks onto a canvas and then connect them together in order to automate a series of manual steps. Capability provided by custom extensions can also be added as functional blocks.
- Use product mode (similiar to powerpoint) to arrange your results into a single window and then export the window as a picture (jpeg, png, bmp).
- Export windows, images, and layers to one of the following file types:
- GeoTiff, KML, ENVI, NITF, Shapefile, PNG, TIFF, JPEG, AVI, MPEG1, BMP, PostScript, ENVI Spectral Library, CGM
- Opticks specific formats for: Raster, Annotation, AOI, GCP, Tie Point, Psuedocolor, Metadata
- Create your own exporter as an extension.
