(Joint Venture) Superserve Corporation - Geodata Systems Technologies, Inc. Sec 1 Version 1.0 of 14

1 Introduction

This is the User’s Manual for the National Housing Authority-Geographic Information System (NHA-GIS) Web Map application. The NHA-GIS Web Map application is a browser-based GIS app that allows authorized users of NHA to navigate and access information on project locations and lot properties on a GIS map-based interface. Although the application can be accessed using any web browser, the application works best when using any of the following:

Internet Explorer 10 or higher

Microsoft Edge

Google Chrome

Mozilla Firefox

Safari 3 or later It is important that users have reliable network and Internet connection to be able to use the application. Furthermore, users of the app will be required to input a username and password in order to successfully get into the application and access its various functionalities. For any concerns or questions regarding the NHA-GIS Web Map application, you may contact the Corporate Systems and Operations Office (COSO) of NHA.

NHA-GIS User’s Manual National Housing Authority Querying and Searching on the Map


3 Querying and Searching on the Map

3.1 Make area and distance measurements

Aside from map viewing and navigation, the user can also make ground area and distance measurements on the map.


2. Select Measurer.

The Measurer panel will appear on the upper right side of the application’s webpage.

3. To make area measurements, click the leftmost button having the icon .

a) Click the dropdown list and select a preferred unit of measure.

b) Draw a polygon on the map display by clicking once for every polygon corner to be drawn, then double-click to finish drawing.

4. To make distance measurements on the map, click the button and select Measurer. Just the same with the first step, the Measurer panel

opens. In the Measurer panel, click the middle button having the icon .

a) Click the dropdown list and select a preferred unit of measure.



b) Draw a line on the map display by clicking once for every line corner, then double-click to finish drawing.

When measuring distance, a icon is produced once you click on the map.

3.2 Determine coordinate locations

The coordinates of locations may also be determined in the application. This functionality can help the users define the location of a parcel/lot or a point immediately.


2. Select Measurer. The Measurer panel will appear on the upper right side of the application’s

webpage. 3. To display coordinates of the mouse cursor, click the rightmost button

having the icon .

a) Click the location whose coordinates must be determined.

The Measurer panel displays the coordinates of the location in longitude-

latitude format.



3.3 Display project or lot information

Essential information about a project location or lot polygon of interest can be accessed readily from the map. To know the information about a specific project location or lot polygon:

1. Place your cursor over a project location or a lot polygon.

2. Click the selected project location or lot polygon to show its attributes in a pop-up window.

3.4 Find a project location

Aside from displaying information about a project location on the map, the application also allows for finding a project’s location based on its name.


2. Select Tasks. The Tasks panel will appear on the upper right side of the application’s

webpage.

3. Click the Find a Project tab.

4. Type in the name of a project in the text box.

The text box is designed to be predictive, such that suggested values

dynamically show up every time a character is typed in.

5. Click to select any of the values suggested, then click the icon or press Enter on the keyboard to start searching.



The map display zooms in to the location and highlights the lot polygon related to the encoded value. A pop-up window also displays, showing the common code and phase-block-lot number of the selected lot polygon.

3.5 Find lots

Aside from finding project locations, the application also allows finding lot polygons based on known identifiers: common code, beneficiary ID, or phase-block-lot number.


2. Select Tasks.

The Tasks panel will appear on the upper right side of the application’s

webpage.

3. Click the Find a Lot tab.

4. Click a radio box button depending on what information to provide for the lot to be searched i.e. beneficiary ID, common code, or project-phase-lot-block number.

6. Type in the value in the text box (if searching based on beneficiary ID or

common code); or choose values from the dropdown list (if searching based on project-phase-lot-block number).

Similar to the Find a Project tab, the text boxes in the Find a Lot tab are also designed to be predictive, such that suggested values dynamically

show up every time a digit is typed in.

7. Click to select any of the values suggested, then click the icon or press Enter on the keyboard to start searching.

The map display zooms in to the location and highlights the lot polygon related to the encoded value. A pop-up window also displays, showing the common code and phase-block-lot number of the selected lot polygon.



If the value that the user has entered is not yet assigned to a lot polygon in the NHA-GIS database, the application prompts “No result(s) found”.

the query to be run.

6. Click the third dropdown list labelled in this housing project and select a

housing project to be queried.

7. Click OK to run the query.



The map refreshes and pans to the selected housing project and highlights the lot polygons satisfying the query.

Also, the number of records satisfying the query versus total number of lots in the selected housing project is displayed, plus a pie chart showing number of selected records versus unselected records.

Note: The selected lot polygons satisfying the query may not be consistent

with the number of records satisfying query since not all lot polygons are currently assigned with common code values.

8. Optionally, generate a report of the query results by following steps in

section 4: Generating a report.
