Frequently asked questions
- How high is Essex County, New Jersey, and how steep is it?
- The high point of Essex County, New Jersey is 684 ft and its lowest land sits at 0 ft, with an average slope of 4.6% across the county. Elevations are measured from the USGS bare-earth elevation model inside the county boundary.
- Is this topographic map free to use?
- Yes. This map is free to view. A free Land Owl account unlocks the other data layers, parcel boundaries and ownership records.
- Where does this data come from?
- Land Owl draws contour lines from the USGS 3D Elevation Program (3DEP) bare-earth digital elevation model, served through AWS Terrain Tiles, and the elevation figures on this page are measured from that same model inside the county boundary. It is a screening surface at roughly 30-foot ground resolution, not a survey: it will not find a small berm, a ditch or a cut, and no lender, engineer or building department will accept it in place of a site survey.
- What contour interval does this map use?
- The interval changes with zoom, the way it does in the Land Owl app: 50-foot contours with a 200-foot index line when you are looking at the whole county, tightening to 10-foot and then 5-foot contours as you zoom into a parcel.
- Can I use these contours to plan a build or a drainage design?
- To shortlist land, yes — this is enough to tell a flat lot from a steep one and to see which way water leaves a property. To design on, no. These are bare-earth contours off a national elevation model at roughly 30-foot ground resolution; a driveway grade, a pad elevation or a drainage plan is drawn off a site survey.
