The following image represents the distributions of cities and towns across the United States and is one example of the interesting operations you can perform on spatial data. In this section: Spatial Data [page 4] Spatial data is data that describes the position, shape, and orientation of objects in a defined space. Spatial Types and Functions [page 70] The spatial data types can be considered like data types or classes. Each spatial data type has associated methods and constructors you use to access the data. 1.1 Spatial Data Spatial data is data that describes the position, shape, and orientation of objects in a defined space. Spatial data is represented as 2D geometries in the form of points, curves (line strings and strings of circular arcs), and polygons. For example, the following image shows the state of Massachusetts, representing the union of polygons representing ZIP code regions. SQL Anywhere Spatial Data 4 PUBLIC SQL Anywhere Server - Spatial Data Support Two common operations performed on spatial data are calculating the distance between geometries, and determining the union or intersection of multiple objects. These calculations are performed using predicates such as intersects, contains, and crosses. The spatial data documentation assumes you already have some familiarity with spatial reference systems and with the spatial data you intend to work with. Note Spatial data support for 32-bit Windows and 32-bit Linux requires a CPU that supports SSE2 instructions. This support is available with Intel Pentium 4 or later (released in 2001) and AMD Opteron or later (released in 2003). The software provides storage and data management features for spatial data, allowing you to store information such as geographic locations, routing information, and shape data. These information pieces are stored as points and various forms of polygons and lines in columns defined with a corresponding spatial data type (such as ST_Point and ST_Polygon). You use methods and constructors to access and manipulate the spatial data. The software also provides a set of SQL spatial functions designed for compatibility with other products. Example Spatial data support lets application developers associate spatial information with their data. For example, a table representing companies could store the location of the company as a point, or store the delivery area for the company as a polygon. This could be represented in SQL as: CREATE TABLE Locations( ID INT, ManagerName CHAR(16), StoreName CHAR(16), Address ST_Point, DeliveryArea ST_Polygon ) SQL Anywhere Spatial Data SQL Anywhere Server - Spatial Data Support PUBLIC 5 The spatial data type ST_Point in the example represents a single point, and ST_Polygon represents an arbitrary polygon. With this schema, the application could show all company locations on a map, or find out if a company delivers to a particular address using a query similar to the following: CREATE VARIABLE @pt ST_Point; SET @pt = ST_Geometry::ST_GeomFromText( 'POINT(1 1)' ); SELECT * FROM Locations WHERE DeliveryArea.ST_Contains( @pt ) = 1 In this section: Spatial Reference Systems (SRS) and Spatial Reference Identifiers (SRID) [page 7] In the context of spatial databases, the defined space in which geometries are described is called a spatial reference system (SRS). Units of Measure [page 9] Geographic features can be measured in degrees of latitude, radians, or other angular units of measure. Support for Spatial Data [page 11] There are several spatial data types supported by the software. Recommended Reading on Spatial Topics [page 22] Consider the following resources for learning about spatial data. Creating a Spatial Column (SQL Central) [page 22] Add spatial data to any table by adding a column that supports spatial data. Creating a Spatial Column (SQL) [page 25] Add spatial data to any table by adding a column that supports spatial data. Indexes on Spatial Columns [page 26] When you create spatial index, do not include more than one spatial column in the index, and position the spatial column last in the index definition. Spatial Data Type Syntax [page 27] The SQL/MM standard defines spatial data support in terms of user-defined extended types (UDTs) built on the ANSI/SQL CREATE TYPE statement. How to Create Geometries [page 31] There are several methods for creating geometries in a database. Viewing Spatial Data as Images (Interactive SQL) [page 32] View a geometry as an image using the Spatial Preview tab to understand what the data in the database represents. Viewing Spatial Data as Images (Spatial Viewer) [page 34] View multiple geometries as an image to understand what the data in the database represents using the Spatial Viewer. Loading Spatial Data from a Well Known Text (WKT) File [page 36] Add spatial data to a table by using a Well Known Text file (WKT) that contains text that can be used to load spatial data into a database and be represented as geometry. Creating a Unit of Measure [page 40] Create a unit of measure that is appropriate for your data. Creating a Spatial Reference System [page 41] SQL Anywhere Spatial Data 6 PUBLIC SQL Anywhere Server - Spatial Data Support Create a spatial reference system (SRS) that uses an existing one as a template on which to base your settings using the Create Spatial Reference System Wizard. Advanced Spatial Topics [page 43] Several topics are provided for a more in-depth understanding of spatial data. Tutorial: Experimenting with the Spatial Features [page 56] This tutorial allows you to experiment with the spatial features.

STANDARDS TSB 003 MAY1999 BOARD Issued 1965-06 400 Commonwealth Drive, Warrendale, PA 15096-0001 STANDARD Revised 1999-05 Superseding TSB 003 JUN92 Submitted for recognition as an American National Standard Rules for SAE Use of SI (Metric) Units Foreword—SI denotes The International System of Units (Le Système International d’Unités). SI was established in 1960, under the Treaty of the Meter, by Resolutions and Recommendations of the General Conference on Weights and Measures (Conférence Générale des Poids et Mesures, CGPM) and the International Committee for Weights and Measures (Comité International des Poids et Mesures, CIPM) on The International System of Units. The abbreviation "SI" is used in all languages. In 1969, the SAE Board of Directors issued a directive that "SAE will include SI units in SAE Standards and other technical reports." During the ensuing several decades, SAE metric policy evolved and implementation progressed. The SAE’s current metric policy is, "Operating Boards shall not use any weights and measures system other than metric (SI), except when conversion is not practical, or where a conflicting world industry practice exists." Principal driving forces for SAE metrication were: worldwide movement to metric units; enactment of United States Federal metric legislation and the resultant national metrication activity; the international trend in industry and business throughout the world, and the growing international scope of SAE. Currently, the widespread, strong support for international standards harmonization is another key motivating factor in the global metrication movement. TSB 003 (formerly SAE J916) has been updated periodically, to reflect SAE metric policy evolution—as well as developments in the specific, formal content of SI; and in the correct, consistent usage and application of SI...which sometimes is referred to as "the modern version of the metric measurement system." The content of TSB 003 is consistent with international and U.S.
