MSSQLSpatial - Microsoft SQL Server Spatial Database

Introduction

Starting with version 2008, Microsoft SQL Server has a builtin functionality to work with spatial queries. SQL Server supports two spatial data types: the geometry and the geography.

NOTE

At the moment MapSurfer.NET supports only geometry type.

Configuration

This section describes configuration parameters used in MSSQLSpatial data source provider. They are:

Parameter NameValue TypeDescriptionRequired
ConnectionStringDefines the string used to open a SQL Server database.Yes
TableStringThe table name.Yes
GeometryColumnStringDetermines a spatial column that contains data of a spatial data type (e.g., geometry or geography).Yes
SpatialIndexStringDefines the name of a spatial index.Yes
QueryStringThe query used to select data from a database.Yes
ExtentStringSets the extent of spatial data in a table. It is used by MapSurfer.NET Studio to speed up Zoom To Layer function.No

IMPORTANT:

For MSSQLSpatial plugin, SQL Server Management Objects (SMO) and [Microsoft.SQLServer.Types](https://www.nuget.org/packages/> Microsoft.SqlServer.Types/) are required to be installed on a computer. You can also install the required assemblies manually by copying the following files Microsoft.SqlServer.ConnectionInfo.dll, Microsoft.SqlServer.Management.Sdk.Sfc.dll, Microsoft.SqlServer.Smo.dll, Microsoft.SqlServer.SqlEnum.dll, Microsoft.SqlServer.Types.dll into the folder MapSurfer.NET_Installation_Folder\Core\Plugins\Providers\MsSQLSpatial. Dynamic link libraries msvcr100.dll and SqlServerSpatial120.dll need to be copied into Native.x64 (for 64-bit OS) or Native.x86 (for 32-bit OS) directory respectively.

OGR is another data source provider that can access spatial data from Microsoft SQL Server.
