MRF Clean 8.0.2
MRF Clean is a multi-level, multi-tolerance 2D data cleaner.
MRF Clean cleans linear elements, unshared cells and circular arcs. Shapes,
complex shapes, complex chains and curves can also be cleaned if first stroked
to line string elements. You have the option of cleaning circular parametric
arcs in their native form, or stroking them prior to processing.
MRF Clean can:
-
Correct over-shooting
-
Correct under-shooting
-
Perform line weeding
-
Remove duplicate or near-duplicate points and lines
-
Create intersections in crossing linework to ease building of topology
-
Remove or flag dangles
-
Join singly-connected line strings with identical attributes to form longer ones
-
Merge linework which has approximately the same geometry (conflation)
-
Identify free end points for manual review and editing
-
Reduce design file size to save disk space and increase display speed
MRF Clean Graphical User Interface
MRF Clean allows you to maintain inter-level geometric consistency. MRF Clean has the following modules:
- MRF Stroke - It will stroke certain non-linear elements into line strings. The purpose of doing this is to reduce the complexity of the MRF Clean process.
- MRF Simplify – It involves the removal of line string vertices based on a specified tolerance.
- MRF Short Element Processor - MRF Short Element Processor is used to flag or delete elements that have lengths smaller than specified tolerances.
- MRF Extend - MRF Extend is a tolerance-controlled module that is used to extend certain elements—correcting for undershoot—while maintaining linework direction.
- MRF Intersect - It flags and/or creates true and fuzzy intersections. It has element intersection, clustering, and splitting sub-functions.
- MRF Duplicate Remover – It is used to remove duplicate elements from a two-dimensional design file.
- MRF Join – It joins singly-connected elements into longer ones. The benefits of joining are:
- Reduced design file size
- The number of geographic features is reduced, making many mapping/GIS operations more efficient—there will be fewer elements to edit or attach database attributes to.
- MRF Conflation – It changes the geometry of one linear element to match that of another, if the two are approximately the same to begin with.
- MRF Dangle Processor - It either flags the dangle elements (deadends) with a letter "D" at the user specified level or deletes them (if the delete option is chosen).
