1 Introduction

The IER Map Display Extension to ESRI ArcView V3.2 is designed to enable users of the toxicity assessment to visualize analysis of toxicity indexes of the HCMC industrial zones This image processing and manipulation is designed exclusively for ESRI ArcView Version 3.2 The interface helps users in numerically and graphically displaying toxicity indexes for wastes discharged by all industrial establishments located within HCMC metropolis region The interface is available

to all users with a minimum of operator ArcView GIS status It is aimed primarily

at providing non-expert GIS users, i.e users unfamiliar with the ESRI ArcView software

When a model is loaded into the ArcView it is possible to perform importing map data for viewing, comparison of extension maps both visually and numerically and

to exporting analysis results into readily printing layouts The extension is intended

to equip DSF users with the tools they need to exploit DeltaMapper binary raster data for creating and maintaining their GIS content within the ESRI ArcView system With the release of the IER Map Display GIS Extension for ArcView V3.2, additional graphical and database functionalities are available to users to improve their workflows

The IER Map Display Extension also provides a way to organize storing the user’s binary raster data sets into databases It is the best not only for the software to perform data analysis but it is also an excellent recommendation to affectively later data processing performed by the other environmental software users

2 Setting-Up the Extension

The following section describes the procedures for preparing and loading the IER Map Display Extension into ESRI ArcView and then running a sample session The documentation assumes the user has some knowledge of the ESRI ArcView package as the different basic ArcView operations are referred to without explanation The user can find a full explanation of the ESRI ArcView operations

in the ESRI ArcView software guide

In some cases the user may have to import additianl ESRI Extensions for ArcView (Spatial Analysis, Database, etc.) which are normally available together with the ESRI ArcView installation

The setup process comprises only one running of the installation file (Setup-MapToxicity.exe) The user can use either the run command in WinXP Start-up menu or by double-click the set-up file in Window Explorer A familiar welcoming window of IER Map Display installation process will be displayed and the user will have to follow all instructions apearing on the computer screen

If the installation file is not available, the user has an alternative to unzip intalation file “Steup.zip” into C drive

The user’s computer hardware and software should meet the following minimum requirements

Drive

v.3.2 with Spatial Analysis, Database extensions

The more powerful PC will enable the IER Map Display run faster and with better performance

2.1.2 Data Requirements

Data used by the IER Map Display are toxicity indexes obtained from chemical and biological analysis of wastes discharged by 12 industrial zones located in HCMC metropolis area

The organization of folders should

be in hierarchical order as follows

o MapDisplay as parental level

o Map-IndZones, ToxicityData and Help as secondary level folders

A visual organization of the folders is presented in Figure 2.2

2.2 Testing the Installation

If the installation of the IER Map Display Extension was successfully, the menus and tools system of the ArcView will look like in Figure 2.3 when the user loads the extension into a ArvView project map (the user is advised to refer to ArcView User Guide for manage extensions in ArcView)

Figure 2-3 Pull-down menus and tools created by the extension

Figure 2.2 Folder organization

The user has to follows every step described in the present report to make map analysis using standard data provided in the Installation CD-ROM

3 Using the Extension

The IER Map Display Extension is accessed by selecting the appropriate name from the ArcView File pulldown menu and then clicking the ‘IER Map Display’ checkbox When the extension starts up the user is presented with the display shown in Figure 3-1 This consists of new tool item and e new button in addition

to default menus and tools of ESRI ArcView

Figure 3-1 IER Map Display Extension start-up screen

3.2 Toxicity View

The IER Map Display Extension enables user to visualise the toxicity data previously stored in a database file

Figure 3-2 Accessing IER Toxicity tool

When the toxicity tool is activated, by clicking the button , the user can press left-mouse button at any of 12 industrial zones (green cycles on the map) to get access to dialog window for examinning toxicity idexes as shown in Figure 3-3

Figure 3-3 Window for starting displaying toxicity values.

Figure 3-4 Pull-down combo box for showing toxicity at other IZ.

The user can use this dialog window to brow to other IZ (Figure 3-4) for examinning their toxicity parameter values or to displaying graphs to compare toxicity levels from different IZs

As stated in the previous section, by using graph button in the dialog window the user can draw graphs to visually compare toxicity data sets The user is also provided with the facilities to locate what IZ wastes are at critical toxicity levels or

to display a variety of additional information and to change the configuration of the view

A “X” sign is displayed closely to a value of index means that index has value greater than allowed value (standard value or tolerance) An example of an IZ with many critical toxicity levels is presented in Figure 3-5

Figure 3-5 Critical values were identified by an “X” sign.

The process to get graphs for comparison values of toxicity from different IZ is started by pressing button “Do thi” located in the lower-left corner of the dialog window (Figure 3.6)

Figure 3-6 Button “Do thi” for starting graph session.

Once the desired index is selected, the tool will draw a graph as shown in Figure

3-8 The user then can use ESRI ArcView tools either to modify or to print the graph

Figure 3-8 Graph for toxicity comparison.

The user is expected to save the selected graphs to new names because all these graphs will be removed in case the button “OK” is pressed

The IER Map Display Extension provides users with the facilities to manage the toxicity databases including standard values by using the pull-doen menu (Figure 3-9

Figure 3-9 Pull-down menu for database management.

A summary of updating toxicity databases is as follows:

• Selection of item “Update Database” from the pull-down menu The dialog for updating DB will be displayed on the computer screen

• Browse to desired IZ by using the combo box “Khu Cong nghiep Khac”

• Enter new data values wherever necessary

• Press the button “Save” to replace old values with the new ones

Figure 3-10 Dialog window for database management.

Figure 3-11 Dialog window for database management.

The process to update standard values is similarly with the procedure for storing new toxicity values The only difference is the apperance of the dialog window (Figure 3-12)

Figure 3-12 Dialog window for tolerance database management.

3.5 Getting Coordinates of Industrial Zones

The MRCS-IER Map Display Extension includes also a popup tool for manually getting Cartesian coordinates of industrial zones This tool will be available (Figure 3-13) when the user point the mouse to an IZ location on the map and right-click the mouse help

Figure 3-13 The popup menu after pressing the right-button of the mouse.

The “Get Point Coordinate” item on the menu allows users to save the current location’s X-Y coordinates into the toxicity database in a friendly procedure as shown in Figures 3-14 and 3-15

Figure 3-14 The list of IZ locations.

Figure 3-15 The popup menu confirmation window for updating coordinates.

In addition to the above mentioned tools, the MRCS-IER Map Display Extension also provides help tools for improving users’ convenience The help system can be accessed at different locations and stages of the software using process

4 Recommendations for Further

Developments

The present user guide was composed with the purpose to provide users of the IER Map Display Series as detailed as possible the procedure to successfully carrying out GIS analysis of toxicity data obtained previously from chemically, mechanical and biological analysis of wastes discharged by HCMC industrial zones The user should have a minimum level of ESRI ArcView V3.20 user knowledge and a sound acquaintance of file and folder management A higher level of ESRI ArcView and its extension such as Spatial Analysis, Geoprocessing, and Imagery Data Format is desired

Due to limited available time for the development, the present version of the software is obviously still lacking a number of useful features The future releases

of the package will rectify the following shortages

• Vietnamese text in every interfaces, e.g dialogs, labels, which will make the software expectedly to be more user-friendly with Vietnamese;

• More statistical analysis of toxicity data;

• Development of wider toxicity databases which contains not only physical, chemical and biological wastes analysis data but also other spatial and temporal feature data related to the industrial zones, e.g addresses, industrial characteristics, population, etc.;

• Further development of the package in the direction of representation of real environmental data of IZ in an advanced GIS technological package
