Overview

Pennsylvania’s Department of Environmental Protection (DEP) developed the eMapPA application to organize and report information about Pennsylvania and the Commonwealth’s regulated facilities.  eMapPA translates location data for facilities from the Environment, Facility, Application, Compliance Tracking System (eFACTS) for display on a statewide graphic map interface.

This document provides an overview of the eMapPA interface and basic functions.  The user determines which information the map displays by selecting data layers.  The user may pan and zoom to navigate to an area and identify the displayed sub-facilities.

User Interface

The eMapPA user interface includes two major sections: the “tabbed pane” and the “map area.” 

Tabbed Pane

The tabbed pane consists of a series of tabs along the top edge which determine the options displayed below the tabs.  Use the right-arrow or left-arrow buttons to scroll through the tabs or click the down-arrow to display a list of tabs.  The available tabs are Layers, Legend, Tasks, and Links.  Each tab provides a different function as described in this document.

Layers Tab

The Layers tab displays groups of data layers available for selection.  Selecting a data layer displays related data points on the map.  A layer name listed in black is visible at the current map scale.  A layer name listed in grey cannot be seen at the current map scale regardless of whether it is selected.  Zoom in closer to see the data.

The data layers are grouped and sub-grouped.  Click the plus icon () next to a layer group to display additional sub-groups or individual layers.  A checkmark () in the checkbox next to each label indicates the data points for that layer are selected for display in the map area.  Click the checkmark to deselect the layer or click an empty checkbox () to select that layer.

Legend Tab

The Legend tab displays the icons, outlines, and shapes used to represent the selected data layers on the map.

Tasks Tab

The Tasks tab is a multi-function tab used to identity and export data, locate specific areas, perform measurements, and generate a printable map.  It contains five tasks: Buffer a Layer, Extract Data, Locate, Measurement, and Print.

 

Buffer a Layer Task

The “Buffer a Layer” task highlights the radius around a point, line, or shape, which is called a buffer.  The minimum buffer distance is 0.1 miles. 

Additionally, the task can create a list of attributes from a selected data layer and show the locations within the buffered area. The resulting list of attributes can be downloaded as a plain-text, comma-separated values file.

 

 

 

 

 

 

 

 

 

Buffer Sensitive Layer (Data Only) Task

The “Buffer Sensitive Layer (Data Only)” task highlights the radius around a point, polyline, or polygon.  The minimum distance for the buffer is 0.5 miles. 

The task creates a list of attributes from the selected data layer.  The locations of the matching attributes are not shown on the map. The resulting list of attributes can be downloaded as a plain-text, comma-separated values file.

 

 

 

Extract Data Task

The “Extract Data” task exports data from specified layers over a specified area in a downloadable file.  The supported formats are Shapefile (SHP), Geodatabase (GDB), Autodesk AutoCAD (DXF), Autodesk AutoCAD (DWG), and Bentley Microstation Design (DGN).

Locate Task

Use the Locate task to locate a point or area by address, county, latitude/longitude, municipality, or zip code.  Clicking one of the buttons under the locate task displays a corresponding pop-up window in the map area to enter or select the related criteria.

Measurement Task

Use the Measurement task to measure the area inside a shape, the distance between two points, or collect the coordinates of one or two points.

Print Task

The Print task generates a PDF copy of the displayed map area for saving, printing, or e-mailing.

Links Tab

The Links tab contains additional resources related to eMapPA.

·         The “Contact Us” link creates a new e-mail to the DEP Geospatial Data Center.

·         The “Help” link contains this document.

·         The “Layer Information” link provides a text description of the data layers available in eMapPA.

Map Area

Four tabs are available in the map area: Map, eFacts Query, and Advanced Query.  The Map tab displays by default.

Map Tab

The Map tab displays one of four selectable map sources with any data layers selected in the Layers tab overlaid. Change the location displayed in the map area using the pan and zoom tools.

Toolbar

Use the toolbar to select a map source, change the displayed location, or identify data points on the map.  Selecting the “ESRI Streets & Imagery” enables a slider that allows cross-fading between the Streets and Imagery sources.

Zoom In

    The “Zoom In” tool changes the map scale to see more detail on the map.  To zoom in on the displayed map first click the “Zoom In” tool to select it.  Then click and hold the left mouse button, move the mouse pointer to draw a box, and then release the mouse button.  When using a mouse or trackpad with a scroll wheel or scrolling gesture, scrolling up will trigger the zoom tool centered on the location of the mouse pointer.

Zoom Out

    The “Zoom Out” tool changes the map scale to see a larger section of the map.  To zoom out on the displayed map first click the “Zoom Out” tool to select it.  Then click and hold the left mouse button, move the mouse pointer to draw a box, and then release the mouse button.  Drawing a smaller box will zoom out further and drawing a larger box will zoom out “less.”  When using a mouse or trackpad with a scroll wheel or scrolling gesture, scrolling down will trigger the zoom tool centered on the location of the mouse pointer.

Zoom to Pennsylvania

    The “Zoom to Pennsylvania” tool displays the entire state of Pennsylvania in the map area.

Zoom to Previous Extent

    The “Zoom to Previous Extent” tool returns the map to the previous location after using the Pan tool or to the previous scale after using the “Zoom In” or “Zoom Out” tools.  This tool can be used repeatedly until returning to the initial map display.

Zoom to Next Extent

    The “Zoom to Next Extent” tool reverts changes made by using the “Zoom to Previous Extent” function.

Pan

    Use the Pan tool to change the displayed map section by clicking on a point and dragging the displayed map section.

Clear Graphics

    The “Clear Graphics” tool removes highlights, user-drawn lines and polygons, points, and labels from the map area.

Identify

    The Identify tool displays a list of attributes at a specific point on the map.  The tool displays attributes from any currently visible data layers selected in the Layers tab.  Click the Identify tool and then click a point on the map to display a pop-up window.  If the pop-up window displays attributes from multiple layers as determined by the text “1 of n” then click the right-arrow to view the next dataset.

Identify by Polygon

    The “Identify by Polygon” tool displays a list of attributes within a user-specified area on the map.  Click the tool and a pop-up window displays.  Select a layer to display attributes from that layer.  After selecting the layer, click a point on the map to begin drawing a shape.  On-screen prompts provide instructions.

Keyboard Shortcuts

Click in the map area to use the keyboard for the pan and zoom tools.  Use the arrow keys ([á], [â], [ß], [à]) to pan the map up, down, left, and right.  Use the [+] and [-] keys on the numeric keypad to zoom in and zoom out.

eFacts Query

Use the “eFACTS Query” tab to search for eFACTS client, site, and facility records that have coordinates associated.  Records located on this tab can be viewed on the Map tab by clicking the magnifying glass icon ().

Advanced Query

Use the “Advanced Query” tab to search for values in the attributes of a specified data layer.  Records located on this tab can be viewed on the Map tab by clicking the magnifying glass icon ().
