Tuning Spatial Point Data Queries in SQL Server 2012

Spatial Point Data queries require particular tuning efforts to enhance performance and improve overall application through put. SQL Server 2012 introduces a few key new features and improvements to assist you in that goal.

Standardize data storage for geography spatial data type in SQL Server

Geography is one of the spatial data types introduced in SQL Server 2008. One of the characteristic of the geography data type is that it can accommodate any supported geometry based on any supported spatial reference system in the same field. So if the data that is stored in a column of geography data type is not standardized, it can be a very tedious and resource intensive task to figure out the geometry and spatial reference system associated with each value. To deal with this issue, we need to standardize the data stored in a field of that has the geography data type and in this tip we will look at how to deal with this issue.

Working with Spatial Data Part IV - Developing a Geospatial Dashboard (GIS)

In Part IV of the Geo-Spatial series, an interactive dashboard is developed to present and interact with the data.

Working with Spatial Data Part III - Reporting Spatial data using Reports Builder 3.0

Part III of our spatial data series, continues building a demo spatial data app and uses Reports Builder for detailed visual mapping.

Working with Spatial Data Part II - Plotting Shapes and Storing Geocoded Data

Continuing from Part I of the Spatial Data series we model an in-memory/persistent data repository for storing geocoded data and plot the data.

SQL Server Geography Data Type

We are working on the migration to SQL Server 2008 and have geospatial data that we would like to move over as well. As part of our application we house information on locations across the globe. Which data type should we use?

SQL Server 2008 Spatial Index Performance

The institution I work with has decided to migrate their database system to SQL Server 2008. One of the applications uses geospatial data, which consists of millions of rows. I understand that their are indexes that can be used for geospatial data, but have not worked with them. What's the scoop on them?
