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.
