MFworks provides a streamlined graphical environment to allow
users to quickly and easily manipulate their data. The analysis
features of MFworks make use of this environment to improve the new
user learning experience, and to add flexibility to experienced
Raster GIS analysis is critical when trying to identify and
quantify specific relationships within or between images or data
sets. Raster analysis is ideally suited to working with varying data
sets such as elevation, aspect, slope, precipitation, density,
population and other continuous characteristics. MFworks raster
analysis will add a powerful new dimension to your GIS projects.
MFworks was developed to emphasize the potential of raster
analysis. The latest version of MFworks optimizes this technology by
extending the boundaries of traditional GIS analysis. A key feature
to MFworks is the extensive set of standard operations which enable
you to easily execute and visualize detailed analysis. MFworks also
offers a unique, yet simple full featured scripting facility which
is designed to allow you to easily construct, edit and save custom
spatial operations or models.
The analysis features of MFworks offer you the flexibility to
test new ideas, explore new concepts and make more informed
decisions in a quick and efficient manner. MFworks represents the
highest level of raster GIS analysis available on a desktop system.
Expand the scope of your GIS project by applying the powerful raster
analysis capabilities of MFworks.
[ Introduction to Raster Based GIS | MFworks Operations ]
The new MFworks Scripting Dialog Interface had been added to the Operation and Translator modules. This interface contains controls and fields to select operand map layers, set execution options, and to specify additional parameters. The dialog interfaces can also be used to interactively generate spatial modelling scripts when accessed through the Script window.
These Operation Dialog Boxes also provide a Contextual Help
feature which prompts the user and gives a general explanation of
the field they are working with.
MFworks still comes with a full
featured scripting window that allows users to construct, edit and
save cartographic models.
Text can be imported into a script window from other applications
using a text file, or via the clipboard.
The script window makes use of pull down menus and standard cut
and paste techniques.
An Operations Menu has been added to
the main menu bar. This menu accesses the new Operation dialog
interface and allows Operations to be executed one at a time without
having to write a script.
Balloon Help has been added to the system for all the main
windows in MFworks.
Special contextual help is included in all the module dialog
boxes. This help system is automatic and is always available when a
dialog box is open.
A "Commands" menu has been added to the Script window. This menu
allows users to create scripts which: export map layers, import
text/color into legends, export legends as text/PICT files, save
files to disk, delete files from disk, specify information
parameters, and define color sequences.
A pop-up color menu has been added to make it easier to change the
color of a map zone, the color of the drawing zone, and the end
points of a color sequence. The "Other..." item at the bottom of the
pop-up menu can be used to display the standard color picker dialog.
Two items have been added to the "Map/File Names" menu. These
items allow for interactive insertion of input and output file names
using the standard file Finder dialogs.
An extensive set of single map and multiple map layer
transformations that produce spatial measurements, area based
statistics, filtering, and layer superimposition.
Arithmetic functions that can be applied to single and multiple
map layers include: addition, subtraction, multiplication,
division, exponent, summary statistics, as well as trigonometric
and logarithmic functions.
Map data can consist of either single precision floating point
or 32-bit fixed point (integer) values. Floating point data use
six decimals of comparative precision.
A complete self-documenting record is maintained for all maps.
This record includes the histories of all maps used to create the
current map. History information can be used to view the steps
taken to produce a map, or as the basis for new scripts.
