Spatial data represents locations Which properties overlap? Which roads intersect property or each other? How many stores/restaurants/houses/car dealerships are located within a geographical area? Represented by two primary data types Geometry: small areas where curvature of the Earth isn’t so relevant when making calculations Flat Earth model X, Y coordinates Geography: large areas where the curvature of the Earth does matter when making calculations Round Earth model Latitude and longitude coordinates You query for location information as you would any SQL Server data type Data types dictated by the OpenGIS standard Calculations easy to perform (“black box”)

Spatial data represents locations

Which properties overlap?

Which roads intersect property or each other?

How many stores/restaurants/houses/car dealerships are located within a geographical area?

Represented by two primary data types

Geometry: small areas where curvature of the Earth isn’t so relevant when making calculations

Flat Earth model

X, Y coordinates

Geography: large areas where the curvature of the Earth does matter when making calculations

Round Earth model

Latitude and longitude coordinates

Geospatial data in SQL Server Stored in a proprietary binary format Can be input using simple text Parse methods exist to convert the text into the internal storage format Represents areas using Points Linestrings Polygons MultiPoints MultiLinestrings MultiPolygons GeomCollections Polygonal areas must be defined in counter-clockwise direction Interior areas (“holes”) must be defined in clockwise direction Inherently support various calculations and methods Spatial Reference ID (SRID) identifies ellipsoid used (flat/round, meters/feet) Only instances with like SRID can be directly compared

Essentially an OR/M tool Models relational data using entities Can model any relational data source for data access (provider may be required) Application-specific domain You can work at a higher level of abstraction Appropriate amount of information returned Lazy-loaded What is an entity? Structurally like an object Has scalars and relationships Has identity Represent nouns in your application domain Not tied specifically to SQL Server
