PostGIS in motion, moment variation teaches readers of all degrees to put in writing spatial queries that remedy real-world difficulties. It first offers a historical past in vector-, raster-, and topology-based GIS after which fast strikes into interpreting, viewing, and mapping information. This moment variation covers PostGIS 2.0 and 2.1 sequence, PostgreSQL 9.1, 9.2, and 9.3 good points, and indicates you ways to combine with different GIS instruments.

Com> 6 CHAPTER 1 What is a spatial database? 1 shows what the results of such a spatial query might look like. 1 km Suppose you aren’t a mapping user, but are more of a data user. You work with data day in and day out, never needing to plot anything on a map. ” This is the extent of the kind of spatial queries that you can formulate with conventional databases, where data types consist mainly of text, numbers, and dates. ” Without spatial support, these questions would require you to collect or derive additional values for each data point.
Admittedly, Microsoft SQL Server 2012 has probably got the best curve and geodetic support of any database—it’s the only one to support curved geometries in geodetic space. But don’t expect to find numerous output/input functions, such as input/output for KML and JSON, or raster support, or the numerous processing functions that PostGIS has. SPATIALITE Our favorite kid on the block is SpatiaLite, which is an add-on to the open source SQLite portable database. SpatiaLite is especially interesting because it can be used as a low-end companion to PostGIS and other high-end, spatially enabled databases.
PostGIS has always supported the geometry type from its inception. 5. 0 raised the bar more by incorporating raster and network topology support. 1 introduces many more functions, perhaps the most important feature it provides is faster speed, particularly for raster and geography operations: Geometry—The planar type. This was the very first model and it’s still the most popular type that PostGIS supports. It’s the foundation of the other types. It uses the Cartesian math you learned about in high school geometry.
