  • Dr. John E. Harmon

ArcView Extension
  • Low Cost – 40$ (site license available)
  • Single file  svgm2.avx sent by e-mail
  • Place in c:\ESRI\AV_GIS30\ArcVIew\Ext32
  • http://www.svgmapper.com/
  • Also requires free Scalable Vector Graphics Viewer client from Adobe http://www.adobe.com/svg/viewer/install/main.html



3
What Does it Do?
  • Creates a set of html, Scalable Vector Graphics files and javascript file from an ArcView view through the extension
  • Requires a template html file that comes with the program.
  • Writes out the data you specify to an xml file (\data\i_00.xml)
  • You can specify map tip field also
4
SVG Files (just xml – you can edit with text editor)
  • View.svg – main map
  • Legend.svg – legend file
  • Overview.svg – small overview map
  • Info.svg – information file, e.g. scale, x/y values, map tip information
5
Html and Javascript files
  • Map.htm – main file
  • \data\data.js – contains the Java scripting that makes it work
  • Browser must be Java-enabled


6
English Template File (template_en.htm)
  • Uses html tables to arrange the map, legend, info, overview, search, and other table elements on a 1024 by 768 pixels or large screen

8
MAP.HTM
  • Principle access file (URL in browser, e.g. http://cgissrv1.ccsu.edu/website/mexico/map.htm)
  • SVG viewer software allows for interaction with svg files embedded in table elements, e.g. turn layers on and off (legend.svg), pan/zoom (view.svg), show X/Y values of clicked on features (info.svg)
9
\data\data.js
  • Contains all the Javascript functions to interact with the map
  • Functions accessed from map.htm
10
i_00.xml
  • Contains the data – as it was when the website was created
  • There is no direct link to live data; this is a snapshot of what the view looked like and what the attribute data were the instant you made the web site.
  • This data pops up in an html window/table on the left-click on feature (identify button in ArcGIS)
  • See next page for sample data

Strengths and Weakness
  • Simple to construct
  • Few server services involved; client does most of the work
  • Inexpensive – compares well to programs costing 10 x as much
  • Easy to modify
  • Simple structure
  • Only runs on ArcView 3 – no plans to update to ArcMap 9.x
  • Requires client software other than browser
  • No direct data link
  • Weak query functions
  • Not well designed for large numbers of users
