ArcGIS 9.3 Service Pack 1 Topology Validation Patch

ESRI released ArcGIS 9.3 Service Pack 1 earlier this month. SP1 included an enormous number of fixes and enhancements. Since the release an important issue has been discovered which ESRI has released a patch for.

ESRI® announces the ArcGIS 9.3 SP1 (Desktop, Engine, Server) Topology Validation Patch. This patch includes a fix to an issue that only occurs when validating a geodatabase topology. The geodatabase topology may incorrectly modify the shape of true curves in your data. We recommend that you download and install this patch at your earliest convenience to ensure the highest quality experience when working with ArcGIS 9.3 SP1.

Note that ArcGIS 9.3 Service Pack 1 must be installed before you can install this patch.

Some of the ArcGIS 9.3 Service Pack 1 setups have been replaced to address the following additional fix:

• NIM040214 – Validating geodatabase topology containing overlapping curves may produce incorrect results. Please see Technical Article 35833 for more information.

NOTE: If you’ve installed ArcGIS 9.3 Service Pack 1 prior to November 24, 2008, simply install ArcGIS 9.3 SP1 (Desktop, Engine, Server) Topology Validation Patch to fix this issue. You do not need to re-install ArcGIS 9.3 Service Pack 1.

NOTE: If you’ve already installed ArcGIS 9.3 Service Pack 1 and the ArcGIS 9.3 SP1 (Desktop, Engine, Server) Topology Validation Patch, you do not need to re-install Service Pack 1.

NOTE: To check for the presence of ArcGIS 9.3 SP1 (Desktop, Engine, Server) Topology Validation Patch or the updated 9.3 Service Pack 1 (9.3 SP1), right click, properties, version tab of the file GdbTopo.dll under the <installation folder>\ArcGIS\Bin folder. The File version should read:

GdbTopo.dll = 9.3.1.1851
