Microsoft finally adding support for spatial types to the Entity Framework

May 8, 2011

Microsoft introduced the spatial data types to SQL Server in 2008. Since then, they’ve released multiple versions of the entity framework and Visual Studio, but support in Microsoft’s developer frameworks and toolkits for the spatial data types has always been virtually non-existent. This has required developers to implement “creative” workarounds when integrating SQL Server spatial [...]

Virtual Earth and SQL Server 2008 – A Match Made in Heaven?

May 1, 2008

Johannes Kebeck has an interesting post showing how to get the benefits of the MapPoint Web Service method, FindNearRoute, through the use of SQL Server 2008. He uses a newly-added feature of the Virtual Earth API that allows developers to gain access to a complete returned route-geometry when performing a route. This new feature, however, [...]

Connecting MapDotNet Server 2007 to ArcSDE 9.2

May 11, 2007

I’ve been experimenting quite a bit recently with MapDotNet Server 2007 (from hereon, referred to as MDNS), and I’ll say that I’m pretty impressed. Building maps in MDNS is admittedly more difficult than simply publishing an .mxd with ArcGIS Server – MDNS uses MapServer’s map file format, but the power of gaining access to Virtual [...]

Using ASP.NET AJAX’s CascadingDropDown with SQL Server Database

November 9, 2006

I’ve been using Microsoft’s ASP.NET AJAX implementation since the early “Atlas” beta days, but am just now starting to feel comfortable enough with its stability to use it in actual projects. Most of the sample controls that are included with the framework are remarkably easy (and fun) to setup and use. It’s pretty amazing how [...]

Geodatabase Design and Documentation

I’ve been looking for a better way to design, diagram, and document my geodatabase designs. Visio is my tool of choice for database design. It is easy to use and allows me to visualize and demonstrate the capabilities and limitations of my data model before actually creating the geodatabase. Using Visio, I can generate a [...]

PostgreSQL/PostGIS Installation

August 30, 2006

I’ve worked with PostgreSQL for a while now, but everytime I perform a new install (usually with PostGIS added on soon after the initial install) I am amazed at how simple it is and how smoothly it goes. In the past, I’ve worked on some pretty complex database installs – especially complex, at least for [...]
