shows the development process for a web site using a specific set of technologies: the Apache web server, the MySQL database system, and the PHP scripting language. It takes the reader through the construction of a complete application driven site from design to deployment. Each chapter in the book identifies a task to be accomplished that is necessary for the construction of the site. It suggests a way to go about the required programming, and finally implements a solution based on the discussion. The ideas that are presented and the code that is written are indicative of the way real world tasks are being completed.

The objective of the National Park Service (NPS) Vegetation Inventory is to classify vegetation as ecological community types in each of more than 250 NPS Inventory and Monitoring park units ("parks") in the United States outside of Alaska and to map vegetation to that classification scheme developed for the unit. This guidance is a revision and update of the 1994 guidance on vegetation classification within the NPS Vegetation Inventory (The Nature Conservancy and Environmental Systems Research Institute 1994) and supersedes the 1994 version.

This guidance is a revision and update of the 1994 guidance on thematic accuracy assessment for the NPS Vegetation Inventory (Environmental Systems Research Institute et al. 1994). The revision incorporates the sampling design and analysis principles described by the 1994 version as a sound starting framework and by augments them with practical experience gained by the NPS and its cooperators and contractors at more than 100 NPS parks over 15 years. NPS staff informally interviewed many individuals in and outside the NPS who have been involved in project production and oversight. We evaluated specifically thematic accuracy assessment practices in the field and in analysis at more than 30 NPS parks. As a result, this guidance is designed to be scientifically sound, but also practical to implement. While it specifically addresses NPS objectives, it may also be found useful as guidance for other organizations that assess the accuracy of vegetation maps.
