Getting Familiar with NJ MAP
A Resource for the Garden State

Our themes are packaged to provide a guided approach to a number of environmental topics. We are continually expanding and developing our environmental themes.

Each municipality has a locator map, list of available themes, neighboring municipalities as well as up-to-date information regarding municipal resources, Sustainable Jersey certification status and a link to the municipal web page. Every theme uniformly presents a relative scale map with a brief overview, chart and controls tab.

Structure Our Approach

Why Themes and not Layers?

Many web-based GIS platforms provide the user with every possible layer. While seemingly "full disclosure", is actually limiting, as it requires significant investment in exploring the available layers to determine what is relevant. While this method may be the manner in which most GIS professionals operate, it is confusing and inaccessible to the average person. An "idea at a glance" is what is offered through our themes. By taking a thematic approach to the available data, NJ MAP aims to provide the public with an easy-to-navigate map and opportunities to explore the data further. Simply providing a list of layers forces the user to explore first, before he or she can get the "big picture" view of the issues effecting the area.

Map MarkerCustomizing the Map

Each theme is presented using a common framework. The map is on the left hand side. Use the +/- to zoom in and out of the current map extent. The cursor allows you to pan the map. By clicking on any point within the map, Bird’s Eye View will appear over the navigation panel on the right. To exit this, click the red “X” in the top-right corner of the Bird’s Eye display.

At the right is a control panel, divided into a series of tabs. Present on every theme is the “Controls” tab, through which you are able to:

  • Toggle theme layers on or off
  • Adjust opacity – use the slider bar to set the transparency of all layers – 0% will render all layers invisible.
  • Change the background aerial imagery by year, 1930, 1995, 2002, 2007, 2012

In order to maintain fast load times, parcel boundaries are drawn only at the two highest zoom levels. In addition, the GeoLab understands that many themes would benefit from the ability to search by address or block and lot. This functionality is currently under development and will be offered in future update to NJ MAP.


In addition to the thematic viewer, NJ MAP conducts workshops throughout the year to share best practices on idea execution in a focused setting. Workshops are occurring throughout New Jersey and can be requested at anytime by emailing

QuestionsFrequently Asked Questions

  1. What is NJ MAP?

    NJ MAP (Municipal Asset Profiler) is a publicly accessible, municipally-focused portal that takes a thematic approach to data visualization.

  2. What does NJ MAP do?

    NJ MAP provides non-GIS experts the ability to explore the massive amount of environmental GIS data available in a guided fashion.

  3. Who is NJ MAP intended to serve?

    NJ MAP is intended to serve municipal stakeholders involved environmental, land use and sustainability decision making. Intended users include Sustainable Jersey Green Teams, municipal planning boards, environmental commissions, land trusts, watershed organizations and concerned citizens among others.

  4. What makes NJ MAP Different than other NJ mapping services?

    The NJ MAP vision is to make GIS data and usage as easy to access and utilize as a smart phone. In fact the interface is designed to work well on a smart phone and allow anywhere access to information that can benefit sound decision making.

  5. How does NJ MAP coordinate data from different sources?

    In the first phase of NJ MAP development, a "data bridge" was created that allows sharing of data between various web-based mapping servers. Data from governmental, NGO and private sources can be integrated into NJ MAP's thematic-based delivery approach.

  6. Who are the Current Collaborators partnering in the NJ MAP project?

    To date, direct partners in NJ MAP development include the Geraldine R. Dodge Foundation, NJ DEP ENSP - Landscape Project, NJ SADC, and Green Map Systems. The Rowan GeoLab will continue to establish partnerships and collaborations with the NJ MAP project. Through the extensible nature of NJ MAP, other on-line mapping services will be able to coordinate and share data.

  7. What is the long term vision of NJ MAP?

    We envision NJ MAP becoming ubiquitous throughout New Jersey municipalities to be used as a first line of geospatial and environmental information for better decision making. NJ MAP’s thematic approach is modular and continually expandable to meet future needs. Future development will allow crowd-sourcing of data to facilitate local users creating data that can further develop NJ’s geospatial data resources.
