Cleaning OGR imported data (Simple Feature data)
The import of areas with v.in.ogr requires a subsequent run of v.clean to update the map to a topologically valid structure (removal of duplicate collinear lines etc).
"Cleanup" is a generic label and is a subset of "maintenance". It encompasses all remedial work that needs to be done, whereas other maintenance lists may contain suggestions for improvement to intact articles.
Clean out M:\
Because raster grid datasets take up a lot of space, you should delete any unnecessary files from M:\. Delete everything from your removable drive before starting the exercise.
Clean: Process for identifying and correcting potential errors in digital map line work.
Cleaning up After Mistakes in ArcCatalog

5-69. Keep the lenses and reflectors clean. Always use lens paper or other material intended for cleaning optics (antistatic lens paper, a cotton wad, or a lens brush).
Raster Cleanup
ArcScan for ArcGIS also supports tools for performing simple edits on raster images. You can draw, fill, and erase raster cells, all within an edit session.

cleaning
Improving the appearance of scanned or digitized data by correcting overshoots and undershoots, closing polygons, performing coordinate editing, and so on.
The clean dichotomy of discrete/continuous is muddled by cross-over data such as speed limits (ratio) assigned to the features on a road map (choropleth).
Wearing clean white cotton gloves when handling microfilm will prevent the naturally occurring oils, acids, and residues on your hands from coming into contact with the emulsion and film.
"Katrina Clean Up"

Admittedly, the cleaning-up process took Dr. Wheller a few hours ... thinning out nodes, labeling all the arcs he wanted to keep, adding new arcs where the linework on the original map wasn't too good, ...
What is needed is cleaner land-use data separate from elevation contours. One convenient source of this type of data is the USGS Digital Line Graphics (DLG) data base.
dangle length Minimum length allowed for dangling arcs during the CLEAN process. CLEAN removes dangling arcs that are shorter than the dangle length.
Batch Processing of Address DataOften also called Address Cleaning, this is the automated process of updating or correcting addresses.
Such soils ought to be regularly summer-fallowed once in six, or at least once in eight years, even when they are comparatively in a clean state, as they contract a sourness and adhesion from wet ploughing, ...

If you make significant or multiple edits after following the processes in GIS Settings for FPA-PM and Shapefile Creation , you may have to convert the shapefile back to a coverage and use ArcMap or ArcInfo to build or clean the coverage, ...
GnssObs reads, cleans, and decimates the RINEX data and converts the data into the NAPEOS internal tracking-data format.
It defines the resolution of a coverage resulting from the CLEAN operation or a topological overlay operation such as UNION, INTERSECT, or CLIP.
G
gazetteerA work of geographic reference that supplies place name and location information.
In a vector based GIS, boundaries between polygons of common reclassed values should be dissolved to create a cleaner map of homogeneous continuity. Raster reclassification intrinsically involves boundary dissolving.
The net result was a database, with all coverages cleanly lining up and attribute information available at every level. The integration was performed within 80 hours by two analysts.
it is unlikely that the building and cleaning operations will be able to automatically sort out area objects unambiguously from the resulting jumble
some systems require the user to identify junctions between digitized "noodles" explicitly ...

These reductions have come through innovations that are delivering cleaner, more energy-efficient aircraft and engines as well as ground equipment.
The real question is: What do I want to learn from this mathematical distortion of a roundish, lumpy, untidy world depicted on a clean, flat sheet of paper? Maps for different purposes use different projections.
