editing Flashcards
topology
spatial relationships between features, adjacency, connectivity, intersection, or overlap; must be maintained to ensure logical consistency
dangle
lines that are supposed to connect but don’t actually, creating an error in logical consistency
snapping
ensures that nodes of lines and vertices of polygons match up preventing dangles
snap tolerance
how close the cursor must be to existing features for snapping to happen
point snapping
matches a new vertex to an existing point in a point feature class
end snapping
matches a new vertex to the endpoints of existing lines
vertex snapping
matches a new vertex to any vertex on an existing line or polygon
edge snapping
constrains added features to meet the edge of an existing line or polygon
coincident boundaries
share exactly the same x,y pairs for two polygons boundaries, if not, there will be gaps or overlaps
schema changes
modify the structure of the data itself such as adding or deleting fields
editing
changes that affect only features within a feature class via the edit ribbon
create features pane
adds new features to a data set, contains at least one feature template for every layer of a map, includes construction tools for each layer
sketch
provisional object shown when a line or polygon feature is being created showing each x,y vertex and the segments connecting them
general editing menu
opened by right clicking the map while the edit ribbon is open, contains selection, repositioning, and modification tools
sketch menu
when sketching, contains specifications of angles, length, or distances
