Optimize MapTips for the visible scale of layers.Ĭreated dimensions are populated with Null values.ĪrcGIS Pro 2.6.6 fixes the issues listed below and includes the fixes listed under 2.6.0, 2.6.1, 2.6.2, 2.6.3, 2.6.4, and 2.6.5. Stop editing (save) is looping 10x if the call times out with a services workspace. Upgrade can create incorrect conditional index on GDB_Locks table.ĭeadlock can be encountered when multiple connections hold exclusive locks on the SDE_process_information and SDE_table_locks tables.Ĭonnections are blocked by exclusive table lock on SDE_process_information. In ArcGIS Pro, when adding a layer using the ' Add preset - Subtype Group Layer' option, the incorrect version name is displayed under the ' Differences' tab while viewing the version changes.ĭeadlocking may occur on SDE_branches and SDE_branch_tables_modified tables during simultaneous reconcile and post operations. Poor performance when placing trace locations in a utility network with a large number of subnetworks due to query of SubnetLine.

The ArcInfo commands, CLEAN and BUILD, enforce planar topology on data and update topology tables. Adjacent lines are connected through nodes, and this information is stored in the arc-node table. A coverage explicitly stores topological relationships among neighboring polygons in the Arc Attribute Table (AAT) by storing the adjacent polygon IDs in the LPoly and RPoly fields. An ArcInfo coverage is a familiar topological data structure. In GIS, topology is implemented through data structure. Because features can exist only on a plane, lines that cross are broken into separate lines that terminate at nodes representing intersections rather than simple vertices. Through planar enforcement, spatial features can be represented through nodes (0-dimensional cells) edges, sometimes called arcs (one-dimensional cells) or polygons (two-dimensional cells). Mathematical topology assumes that geographic features occur on a two-dimensional plane. Today, topology in GIS is generally defined as the spatial relationships between adjacent or neighboring features. The problem that led to Euler's work in this area, known as "The Seven Bridges of Königsberg," is described in the accompanying article "Conundrum Inspires Topology." More recently, the United States Census Bureau, while preparing for the 1970 census, pioneered the application of mathematical topology to maps to reduce the errors in tabulating massive amounts of census data. In 1736, the mathematician Leonhard Euler published a paper that arguably started the branch of mathematics known as topology. Why should GIS users care about topology? What are the advantages and disadvantages of storing polygon data in shapefiles rather than coverages? But ask these same folks about how topology is handled in shapefiles and the nodding heads give way to shrugging shoulders. When asked if topology is a key concept of GIS, most GIS users will nod their heads in agreement.
