<H1>GeoTools Demos and Tutorials Package</H1>
<H2>Introduction</H2>
<P>The GeoTools open source java mapping toolkit is a flexable library of rutines and objects that can be used
to build interactive web based applets as well as stand allone applications.</P>
<P>The GeoTools package is not an application in its own right however, only a toolkit, so in order to place a
map on the web, or into an application small amounts of additonal code is required.</P>
<P>This package aims to provide a suite of small applets, and latter applications, that can either be used 'as
is', or used as a starting point for more addvanced programs. (Or you might just want to canabalise bits out of
each one)</P>
<H2>Requirements</H2>
<P>GeoTools 0.7.9dev1 (included in jars folder) <BR>
Java 1.1 or later<BR>
suns Collections package (available in full from the geotools ftp site, jar file can be found in jars directory)</P>
<P></P>
<H2>The Demos</H2>
<P>The following demonstrations have been ilustated with the aim of providing clear examples of GeoTools usage, as a result
there is a minimum of non-geotools related code, for example code for error handling is not as much in evidence
as perhaps it should be.</P>
<P>
<H3>Example 1</H3>
<P><A HREF="Example1.html">View</A><B></B></P>
<P><B>Description:</B></P>
<P>A very simple applet that shows how a shapefile can be read and displayd in an applet along with a standard
toolbar.</P>
<P><B>Customizing:</B></P>
<P>The applet tag contains a single param tag 'shapefile' that specifies the relative address of the shapefile
to load.</P>
<P><B>Key classes introduced</B></P>
<P>geotools.ShapefileReader<BR>
geotools.Theme<BR>
geotools.Viewer<BR>
wideges.ToolBar</P>
<H3></H3>
<H3>Example 2</H3>
<P><A HREF="Example2.html">View</A><B></B></P>
<P><B>Description:</B></P>
<P>An extension of example1 that show how to set up tool tips</P>
<P><B>Customizing:</B></P>
<P>The applet tag contains two tags :<BR>
'shapefile' the relative address of the shapefile to load.<BR>
'tooltip' the name of the colum to pull the tooltips from</P>
<P><B>Key classes introduced</B></P>
<P>geotools.GeoData</P>
<P></P>
<H3>Example 3</H3>
<P><A HREF="Example3.html">View</A><B></B></P>
<P><B>Description:</B></P>
<P>An extension of example2 that show how to shade a map</P>
<P><B>Customizing:</B></P>
<P>The applet tag contains three tags :<BR>
'shapefile' the relative address of the shapefile to load.<BR>
'tooltip' the name of the colum to pull the tooltips from<BR>
'shadeby' the name of a data column </P>
<P><B>Key classes introduced</B></P>
<P>geotools.Shader<BR>
geotools.ClassificationShader<BR>
geotools.Key<BR>
</P>
<H3>Example 4</H3>
<P><A HREF="Example4.html">View</A><B></B></P>
<P><B>Description:</B></P>
<P>A simple extention of Example 3 introducing a new navigation widget</P>
<P><B>Customizing:</B></P>
<P>The applet tag contains three tags :<BR>
'shapefile' the relative address of the shapefile to load.<BR>
'tooltip' the name of the colum to pull the tooltips from<BR>
'shadeby' the name of a data column </P>
<P><B>Key classes introduced</B></P>
<P>widgets.ZoomLevelPicker<BR>
</P>
<H3>GraphApplet Example</H3>
<P><A HREF="GraphApplet.html">View</A><B></B></P>
<P><B>Description:</B></P>
<P>A fairly complete applet showing how a graph and chart can be linked through a highlight manager.</P>
<P><B>Customizing:</B></P>
<P>The applet tag contains a large number of tags :<BR>
param name="shapefile" value="nameOfShapefileWithoutExtension"<br>
param name="tooltip" value="nameOfColumn"<br>
param name="groups" value="numberOfGroups"<br>
param name="groupXcol" value="nameOfColumn" // for each group<br>
param name="groupXcolor" value="#rrggbb hex colour reference"<br>
param name="groupXname" value="Description of group"<br>
<P><B>Key classes introduced</B></P>
<P>widgets.PieChart<BR>
geotools.GeoLabel<br>
