ER Mapper is a powerful new raster image processing product designed to run
on Sun-4's and Sparcstations. It enables users to develop and apply
sophisticated image processing algorithms without having to write special
software. The product is designed to be easy to use for both expert and
novice using the X Window System with the OpenLook user interface.
ER Mapper has been used to process many different types of data including
satellite, geophysical, geochemical, and seismic.
User applications
-----------------
Environmental studies
Environmental Impact monitoring
Mining Exploration
Vegetation Mapping
Forestry
Natural Resource Management
Land Management
Waste and Pollution Management
ER Mapper Features
------------------
- Multiple image windows may be opened (including windows on other
displays on the network).
- Supports 1 bit, 8 bit and 24 bit X-11 displays. A copy of X11R4 is
supplied that supports the RasterOps 24 bit display on SPARCstations
under X-windows.
- The following data types are supported: signed or unsigned 8, 16, and 32
bit integers, and 4 or 8 byte IEEE floating point. The handling of the
various types is done automatically by the software.
- Datasets that can be processed with ER Mapper include: Landsat TM and
MSS, SPOT MSS and panchromatic, AVHRR (NOAA), DTM, VLF,
radiometrics, magnetics, geochemical, gravity, AVIRIS and resistivity.
Examples of most of these types of datasets are supplied with the
product.
- There is no limit to the size of datasets or the number of bands per
dataset.
- Different datasets can be combined in a single image.
- Formulae for combining bands (eg: ratios, differences, principal
components, NDVI's etc) can be defined by the user and saved under a
specific name for later re-use. All standard operators (+, -, /, *) and
mathematical functions (log, exp, sin, cos, etc) are available for use in
formula.
- Statistics (including number of cells, minimum, maximum, mean, median,
covariance matrix, correlation matrix, eigenvalues, and eigenvectors)
can be calculated for specified regions and used within formulae.
- Filters (convolutions) can be defined by the user and saved under a
specific name for later re-use. Floating point numbers may be specified
in convolutions and there is no size limit for a filter.
- Images can be artificially shaded from any elevation or sun angle.
- A real-time sun angle shading facility is provided.
- Classification of images is supported.
- Vector data may be overlayed on top of the raster image. Vector data
is stored as true vector data, not as rasterised data.
- Output to hardcopy devices is supported. These include colour printers
and film-writers. ER Mapper automatically strip prints to generate large
hard copy printouts.
- Many data formats can be read with the import utilities supplied with
ER Mapper.
