MRF
Clean for MapObjects is a standalone map cleaning software package
running in Windows platform. It cleans ESRI Shapefile. MRF Clean for
MapObjects 2.0 packed MRF Clean and MRF Flag Editor together. It provides
a graphical user interface for shape file displaying, cleaning and
editing. MRF’s industry-leading Multi-Layer, Multi-Tolerance data clean
technology make MRF Clean For MapObjects very unique and powerful. Figure
1 is a general user interface of the product.

MRF
Clean can:
- Correct
over-shooting and under-shooting
- Perform
line weeding
- Remove
duplicate or near-duplicate points and lines
- Create
or flag intersections in crossing line work to ease building of
topology
- Flag
or delete short elements and dangles
- Join
singly-connected polylines with identical attributes to form longer
ones
- Merge
line work which has approximately the same geometry (conflation)
- Identify
free end points for manual review and editing
- Reduce
shape file size to save disk space and increase display speed
Multi‑Layer,
Multi-Tolerance capability is one of the key features
offered by MRF Clean. To the best of our knowledge, MRF Clean is the only
multi-level, multi-tolerance data cleaning package on the market. With
multi‑tolerance data cleaning technique, points with a larger tolerance
will be moved to points with a smaller tolerance. In this way,
inconsistencies such as the overlap or gap between different boundaries
can be corrected by moving the less accurate boundary to the more
accurate boundary. When input points have identical tolerances, the
movement of points are performed in such a way that straight lines are
kept straight - a very desirable behaviour for many GIS/LIS applications.
MRF
Clean is the result of many years of research and
development. The state of the art technology pioneered by MRF Systems
Corp. makes MRF Clean extremely efficient and robust. Extensive testing
and user feedbacks indicate that MRF Clean can improve the quality of
data conversion and data editing for mapping, GIS, and AM/FM
applications, and, at the same time, increase productivity by two to ten
times.
MRF
Flag Editor
MRF
Flag Editor is designed for use in conjunction with MRF Clean. It
assists the user in identifying and editing the flags, such as flag free
end points “D”, intersections “X”, and short elements “S”. See Figure 2.
MRF Flag Editor is designed to guide the user directly to these flags so
the user may review the line work and make editing changes to the
linework.

Editor for MapObjects
MRF
Flag Editor allows the user to visit each flag efficiently. It makes the
current flag the window center, and highlights the flag with the current
highlight color. The user can zoom in and zoom out while keeping the
current flag highlighted. The user can edit (delete or modify) the
flagged elements using editing tools provided in the product.
