There's a good answer over at Stack Overflow, which goes a little something like this: The geography type is a little bit more restrictive than geometry. It can't cross different hemispheres and the outer ring must be drawn counter-clockwise. The rest can be found here. Another article goes into some more detail: If you’re looking for the ...

No, you do not need ArcGIS Server to edit your MS SQL Server database. If you want to continue to interface with ArcMap/ArcCatalog without a ArcGIS Server license you do have at least one other (albeit non-free, but definitely cheaper than an ArcGIS Server License) option. I need to be able to connect to the ms sql server and import, export, create, and ...

To be able to work with a geodatabase stored in SQL Server you would need at least ArcGIS Server Basic Workgroup (see matrix here). You can work with simple features in ArcMap, but no geodatabase editing or alike will be available. Since you have ArcGIS Desktop (I assume you have Standard or Advanced), you get automatically access to geodatabase stored ...

Maybe check out the properties of Projected Coordinate Systems, to get a view into their utility? There are 3 aspects or properties presented in Projected Coordinate Systems that establish their utility and rationale. Any projection of 3D space on a 2D surface will of course exhibit distortion versus reality. Depending on your application, using a specific ...

You may use ListWorkspaces method (once you make the connection) to list the existing databases within SDE: Lists all of the workspaces within the set workspace. Search conditions can be specified for the workspace name and workspace type to limit the list that is returned. workspaces = arcpy.ListWorkspaces("*", "SDE") for workspace in ...

ArcGIS is very sensitive to database names. You cannot restore data unless the database name is identical. You will need to use Feature Class to Feature Class or a copy/paste, or any of the other ways to copy data with Desktop or ArcPy (the list of options can be daunting). All transfers should be done as the data owner(s), not as the administrative 'sde' ...

The fix is defining a filterType parameter in the OpenLayers.Control.GetFeature constructor: new OpenLayers.Control.GetFeature({ filterType: OpenLayers.Filter.Spatial.INTERSECTS, ... The default filterType is OpenLayers.Filter.Spatial.BBOX that results correctly in an uncertain Filter() query in SQL Server, when a spatial index is set. If ...

The reason databases implement R-tree indexes for spatial is because they are faster than geohashes or searches on separate x and y indexes. The problem with geohashes, is that you have to search 9 quadrants, not just 1, to do proximity type searches -- see geohash limitations. They are useful in databases that lack R-trees, to allow the expression of an ...

That data appears to be in the following coordinate system based on the files I found here. You need to reproject/transform all of your data to be in the same coordinate system, whether it be on the fly in GIS software, or permanently in the data itself. Clarke_1866_Albers Authority: Custom Projection: Albers, False_Easting: 0.0, ...

Look into this article. It explains how to apply schema changes with replicas and sync those changes back to the parent. http://resources.arcgis.com/en/help/main/10.1/index.html#//003n000000t2000000
