ArcView Documents
ArcView documents are the primary objects of ArcView.
Each type of ArcView document stores a specific type of information.
Each type of ArcView document provides a different means of interacting with the data.
The ArcView documents are:ViewsTablesChartsLayoutsScript editors

Adding a Theme
A Theme is a digital spatial dataset that has been
added to a View and that has specific properties.
![Page 7: ArcView Documents Francisco Olivera, Ph.D., P.E. Department of Civil Engineering Texas A&M University](https://reader030.vdocuments.net/reader030/viewer/2022032704/56649d6c5503460f94a4b476/html5/thumbnails/7.jpg)

Table Document
Tables are arrays of data organized in rows (i.e., records) and columns (i.e., fields).
Tables can be:stand-alone arrays of data with no geographic information included.components of digital-spatial-datasets in which each record includes a feature shape.
Feature shape
Table name Attribute name
Tables which are components of a digital-spatial-dataset have the attribute “Shape” and are called “Attributes of <theme name>”

Table Properties
Visible allows the user to
hide/unhide table fields.
Alias allows the user to display
a field with a user name.
Visible and Alias do not modify
the table’s original data, but do
affect how a table is exported.

Table Display
Table records can be sorted in ascending or descending
order based on a selected field.

Chart Document
Charts are plots of table attribute values
dynamically linked to Views and Tables.
Chart name
One point per table record

Chart Properties
In the Chart Properties
window the user selects the
Table and the fields of the
Table to be plotted.

Chart Display
Charts can be displayed in six different formats:
Area, Bar, Column, Line, Pie and X-Y.

Layout Display
A Layout can have Live links to the Views, Tables
and Charts displayed in it.
Live links update the Layout automatically
whenever the Views, Tables or Charts are
modified.
Live links should be disabled when the current
display of the View, Table or Chart is satisfactory.
![Page 17: ArcView Documents Francisco Olivera, Ph.D., P.E. Department of Civil Engineering Texas A&M University](https://reader030.vdocuments.net/reader030/viewer/2022032704/56649d6c5503460f94a4b476/html5/thumbnails/17.jpg)
Script Editor DocumentScript editors are text editors for writing scripts in the ArcView programming language Avenue.
Avenue scripts allow the user add further capabilities to ArcView that are not available in the original GUI.
Script name
Avenue code

Script Editor GUI
Scripts can be:
Compiled and run
Debugged
Loaded from the system
or from a text file, or
written to a text file.
![Page 19: ArcView Documents Francisco Olivera, Ph.D., P.E. Department of Civil Engineering Texas A&M University](https://reader030.vdocuments.net/reader030/viewer/2022032704/56649d6c5503460f94a4b476/html5/thumbnails/19.jpg)
ArcView GUI
Default pull-down menus, buttons, tools and
extensions constitute the standard ArcView GUI.
The ArcView GUI can be customized, which means
that the user can develop his/her own scripts, define
pull-down menus, buttons or tools to launch them,
and consolidate them in extensions.
![Page 20: ArcView Documents Francisco Olivera, Ph.D., P.E. Department of Civil Engineering Texas A&M University](https://reader030.vdocuments.net/reader030/viewer/2022032704/56649d6c5503460f94a4b476/html5/thumbnails/20.jpg)
ArcView GUI
Pull-down menus are controls that launch scripts that perform system functions (i.e., File/Save), or spatial analysis (i.e., Zoom to themes).
Buttons are controls that launch scripts that perform system functions (i.e., File/Save), or spatial analysis (i.e., Zoom to full extent). Most buttons are shortcuts for pull-down menus.
Tools are controls that launch scripts that perform spatial analysis based on additional on-screen input (i.e., Zoom in).
Extensions are systems of scripts and corresponding controls, consolidated in a single entity, that can be added-in to ArcView.
![Page 21: ArcView Documents Francisco Olivera, Ph.D., P.E. Department of Civil Engineering Texas A&M University](https://reader030.vdocuments.net/reader030/viewer/2022032704/56649d6c5503460f94a4b476/html5/thumbnails/21.jpg)
ArcView Project
ArcView Project files are text files with extension apr that can be opened with ArcView, and that store all information of the ArcView documents.
ArcView Project files store how the data is displayed in an ArcView document and in which specific ArcView document.
ArcView Project files contain pointers to the digital spatial data, table data and extensions used in the project, but do not contain the data or extensions themselves. However, unless a script is part of an extension, it will be stored in the ArcView Project file.
ArcView Project files cannot be open in other computer unless they are “repathed” and the data are transferred with them.
