Spatial Data Type In Entity Framework Ms sql server 2008 introduced two spatial data types, geography and geometry. the geography type represents data in a round earth coordinate system and geometry represents data in a euclidean (flat) coordinate system. This tutorial is part of "entity framework 5.0: what's new" with expert instructor don kiely. this tutorial will be covering spatial data in entity framework.
An Introduction To Spatial Database Spatial Data Types And Spatial The video and step by step walkthrough shows how to map spatial types with the entity framework designer. it also demonstrates how to use a linq query to find a distance between two locations. Spatial type support was introduced in entity framework 5. a set of operators is also included to allow queries to analyze spatial data. for example, a query can filter based on the distance between two geographic locations. The video and step by step walkthrough shows how to map spatial types with entity framework code first. it also demonstrates how to use a linq query to find a distance between two locations. In entity framework 5.0 spatial data types are supported so now we can create linq queries to query nearby locations, calculate distances and check if locations intersect with an area.
Developing The Future What S New In Entity Framework 5 0 The video and step by step walkthrough shows how to map spatial types with entity framework code first. it also demonstrates how to use a linq query to find a distance between two locations. In entity framework 5.0 spatial data types are supported so now we can create linq queries to query nearby locations, calculate distances and check if locations intersect with an area. Entity framework 5 brings many improvements and spatial data type support in code first is one of them. in this article, i'll use simple steps to develop a console application with entity framework code first and then will explore spatial data types. Entity framework supports spatial data types dbgeography and dbgeometry since version 5.0. let's see how we can use these data types. for demo purposes, we have changed the data type of the location column of course table to geography in sql server 2008 as shown below:. Many developers have been asking since the release of sql 2008 for support of spatial data types in the entity framework. learn more in this post. In this post i show how basic sql spatial data works and then how you can utilize the new features in ef 5.0 to directly access spatial data using your codefirst models.
